Nature’s Traditional Stomach Soother — Why Meadowsweet Was Used Long Before Antacids

The Fragrance of Summer

Long before I learned about salicylates, herbal medicine, or the traditional uses of Meadowsweet, I fell in love with its fragrance.

Every summer, as the creamy flower heads begin to open along the roadsides, ditches and damp meadows of Wexford, the air fills with a scent unlike any other native plant.

Some describe it as honey-like.

Others detect hints of almond, vanilla, or marzipan.

To me, it simply smells like summer has arrived.

Our ancestors appreciated this fragrance too. In times before air fresheners and scented candles, Meadowsweet was often gathered and brought indoors. Bundles were hung in homes, churches, and gathering places, not necessarily for drying, but simply to perfume the air. The flowers were also strewn across floors during celebrations and special occasions, releasing their sweet scent whenever they were walked upon.

It is easy to understand why.

Even today, I find myself pausing whenever I pass a stand of flowering Meadowsweet. Its perfume is unmistakable, and once recognised, it is never forgotten.

Meeting Meadowsweet

Meadowsweet (Filipendula ulmaria) is a member of the Rose family (Rosaceae) and has been treasured throughout Europe for centuries. It thrives in damp habitats, favouring meadows, ditches, riverbanks and wet roadside verges.

In Ireland, it is one of the plants that quietly announces the arrival of midsummer.

The plant grows tall, often reaching well over a metre in height. Its reddish stems support clusters of creamy-white flowers that appear almost frothy from a distance. Beneath them are deeply veined, serrated leaves that are often overlooked in favour of the spectacular blooms.

For me, Meadowsweet is one of the most recognisable wild plants of summer. Once you learn to identify it, you begin to notice it everywhere.

The Queen of the Meadow

Few wild plants have been held in such high regard as Meadowsweet.

Among Celtic peoples, Meadowsweet was considered one of the sacred herbs. It was associated with celebration, abundance and hospitality, and often featured in seasonal gatherings and ceremonies. Some traditions place it among the most revered plants of the ancient Druids, valued not only for its beauty and fragrance but also for the comfort it brought to everyday life.

Its common name reflects the habitats in which it thrives. Growing in damp meadows and along waterways, it often forms large, striking stands that seem to glow in the summer sunshine. When in full bloom, entire roadsides can become awash with creamy-white flowers, creating a spectacle that is difficult to ignore.

Meadowsweet growing along a roadside verge in County Wexford. Its sweet fragrance often reaches you before the flowers come into view.

Historically, Meadowsweet was known as a strewing herb. Before the days of modern cleaning products and air fresheners, fragrant plants were scattered across floors in homes, halls and churches. As people walked across them, the flowers released their scent into the air, helping to freshen living spaces and mask less pleasant odours.

Bundles were also gathered and hung indoors simply for their perfume. While many herbs were dried for medicinal use, Meadowsweet was often appreciated for the fragrance it brought into the home.

Standing beside a flowering patch today, it is easy to understand why our ancestors valued it so highly. The scent drifts on the breeze long before the flowers come fully into view.

Even now, whenever I harvest Meadowsweet, I find myself bringing a few stems indoors. The fragrance lingers gently in the room, connecting us to a tradition that stretches back hundreds of years.

Traditional Uses

Beyond its beauty and fragrance, Meadowsweet has a long history of medicinal use throughout Europe.

Traditional herbalists valued the flowering tops for supporting comfort during fevers, colds and seasonal illnesses. It was also widely used for digestive complaints, including indigestion, heartburn and stomach discomfort.

The herb’s gentle nature made it particularly popular as a tea. In many households, Meadowsweet was considered a comforting plant to turn to when feeling under the weather.

Historically, it was also used to support aching joints and general discomfort. Long before modern medicines existed, people relied on plants such as Meadowsweet to help ease the ordinary aches and pains of daily life.

Today, herbalists continue to appreciate Meadowsweet for many of these traditional uses, particularly in teas, tinctures and seasonal herbal preparations.

While modern science seeks to understand the compounds responsible for these effects, generations of herbal practice have already left us with a rich history of experience and observation.

The Aspirin Connection

One of the reasons Meadowsweet is so often mentioned in herbal literature is its historical connection to aspirin.

The plant contains naturally occurring salicylate compounds, and its traditional use for discomfort, fevers and aches attracted the attention of early researchers. In fact, Meadowsweet played a role in the story that eventually led to the development of aspirin as we know it today.

This connection often becomes the headline whenever Meadowsweet is discussed.

Yet I sometimes feel that focusing solely on aspirin overlooks something important.

For centuries, people valued Meadowsweet not because they understood its chemistry, but because they understood its effects. They gathered it, brewed it, shared it and passed their knowledge from one generation to the next.

The science is fascinating, but the relationship between people and this plant existed long before laboratories became involved.

As with all herbs, Meadowsweet is not suitable for everyone. People with aspirin sensitivity should avoid it, and those who are pregnant, taking medications, or living with specific health conditions should seek appropriate professional advice before use.

My Experience with Meadowsweet

Every herbalist has certain plants that earn a permanent place in their apothecary.

Meadowsweet is one of mine.

As someone who has lived with asthma for many years, respiratory infections have always commanded my respect. Like many people, I have experienced winters where a simple viral illness seemed determined to linger far longer than welcome.

It was during one such winter that I found myself returning repeatedly to Meadowsweet.

The cough was persistent.

The temperature was exhausting.

Recovery felt frustratingly slow.

During that time, Meadowsweet became one of the herbs I reached for most often. Whether taken as a tea or prepared in herbal formulations, it became a trusted companion throughout that period.

Of course, every person is different, and herbs affect individuals in different ways. What works well for one person may not suit another.

Yet some plants leave an impression that stays with you.

For me, Meadowsweet earned its place not through theory, but through experience.

It supported me during a difficult season and has remained one of the herbs I value most ever since.

Why I Continue to Harvest Meadowsweet

Each summer I find myself returning to the same roadsides and damp meadows in search of those familiar creamy flower heads.

I enjoy watching the plant’s journey from tightly packed buds to full flowering clouds of white blossoms.

I admire the rich reddish stems rising above the surrounding grasses.

I appreciate the beauty of the leaves, which are often overlooked in favour of the flowers.

Looking closely at the flowers, I was struck by how much each tiny blossom resembles a miniature Hawthorn flower. Individually delicate and easily overlooked, together they create the creamy clouds that make Meadowsweet one of the most recognisable plants of the Irish summer.


It is only when you pause and examine a flower head closely that you realise you are not looking at one flower at all, but hundreds of tiny blossoms working together.

But more than anything, I look forward to that fragrance.

The scent of freshly cut Meadowsweet is difficult to describe adequately. It is sweet without being overpowering. Delicate yet unmistakable. A fragrance that seems to belong entirely to the Irish summer landscape.

Perhaps that is why our ancestors brought it indoors.

Perhaps that is why it has remained loved for so many centuries.

And perhaps that is why, despite all the modern books, research papers and scientific explanations, I still think of Meadowsweet first as a plant that brings simple pleasure.

Some herbs earn our respect.

Others earn our affection.

Meadowsweet has earned both.

Final Thoughts

Every year, as the first flowers begin to open, I am reminded that some of the most valuable plants are often growing quietly along the roadsides we pass every day.

Meadowsweet asks for little attention.

It simply flowers, perfumes the air, supports pollinators, and continues a relationship with people that stretches back hundreds of years.

For me, it remains one of the true treasures of the Irish summer.

And each year, when that familiar fragrance drifts across a meadow or roadside verge, I know summer has truly arrived.

I hope you feel inspired. Look after your body, and it will keep you healthy.

The Common Weed That Soothes Bites, Burns, Cuts and Coughs

The Humble Wayside Herb That Earned My Respect

There are certain plants that become more than herbs.

They become part of your story.

For me, Plantain is one of those plants.

During the Covid years, when hand disinfectants became a constant part of daily life, many healthcare workers began experiencing severe skin reactions. I was one of them.

What started as tiny blisters quickly became something much worse.

The photographs below show the progression of the skin reaction I experienced during that period, from the early blister stage through to healing and skin peeling.

The itching was intense.

The pain was extraordinary.

My hands developed clusters of fluid-filled blisters that spread across my palms. As they healed, layers of skin peeled away, leaving raw, tender tissue underneath. Simple tasks became uncomfortable. Washing my hands became an ordeal.

Like many others, I sought conventional treatment. Steroid creams were prescribed and oral steroids were tried. Unfortunately, in my case, the problem persisted.

Desperate for relief, I began researching alternatives.

That search led me to a plant that had been growing quietly around me all along.

Plantain.

I gathered fresh Ribwort Plantain leaves from the cliffs near my home, returned to my kitchen and blended them with olive oil to form a simple green mash.

Then I immersed my hands in it.

The relief was almost immediate.

The burning eased.

The itching settled.

The pain diminished.

For the first time in weeks, my hands felt comfortable.

Over the following two weeks, my skin gradually healed.

Years later, I still remember that experience every time I see Plantain growing beside a path or pushing through a crack in the pavement.

Many people see a weed.

I see one of the most useful herbs I have ever encountered.

By Dr Catherine W Dunne MSc.D | M.H.I.T. | Registered Nurse

Meeting Plantain

Plantain belongs to the genus Plantago, with two species most commonly encountered in Ireland:

  • Ribwort Plantain (Plantago lanceolata)
  • Broadleaf Plantain (Plantago major)

Both produce distinctive leaf rosettes from ground level and send up flower spikes during the growing season.

Ribwort Plantain has narrow spear-shaped leaves with prominent parallel veins.   

Broadleaf Plantain produces larger oval leaves that lie close to the ground.

Once you learn to recognise them, you begin to notice them everywhere.

A Plant That Followed Humanity

Plantain has such a close relationship with people that some Native American tribes referred to it as “White Man’s Footprint” because it seemed to appear wherever European settlers travelled.

The seeds cling easily to footwear, animals and equipment, allowing the plant to spread naturally along pathways and roadsides.

Its success lies in its remarkable toughness.

While many plants struggle in compacted soil, Plantain often thrives.

It is a survivor.

Traditional Uses

For generations, Plantain has been valued as a household remedy.

Traditional herbal uses include:

  • Minor cuts and scrapes
  • Insect bites and stings
  • Skin irritation
  • Minor wounds
  • Sore throats
  • Coughs and respiratory discomfort

A freshly crushed leaf was often applied directly to the skin as a simple field remedy when nothing else was available.

Many country children learned this long before first-aid kits became commonplace.

What Modern Herbalists Appreciate

Modern herbalists continue to value Plantain for its gentle and versatile nature.

The leaves contain a variety of naturally occurring compounds including mucilage, tannins and iridoid glycosides.

Traditionally, Plantain has been used to:

  • Support healthy skin
  • Soothe irritated tissues
  • Support respiratory comfort
  • Provide gentle digestive support
  • Calm minor irritation within the body

Its actions are generally regarded as soothing and restorative rather than stimulating.

Plantain does not force the body in a particular direction.

Instead, it offers support while the body’s own healing processes do the work.

Harvesting Plantain

The leaves are usually gathered during the growing season while young and healthy.

 Fresh leaves may be used immediately, tinctured, infused into oils or dried for later use.

In my own herbal preparations, Plantain is one of the plants I return to again and again.

It finds its way into infused oils, balms and herbal blends, earning its place through reliability rather than reputation.

Why I Grow It

The irony of Plantain is that most gardeners spend their time trying to remove it.

Meanwhile, herbalists are often quietly collecting it.

Perhaps that is part of its charm.

Plantain does not demand attention.

It does not produce spectacular flowers.

It simply grows where it is needed, surviving drought, foot traffic, poor soil and neglect.

Yet beneath this unassuming appearance lies one of the most respected herbs in traditional herbalism.

Sometimes the most valuable plants are the ones growing right beneath our feet.

Final Thought

Several years after my own experience, a patient showed me hands that looked remarkably similar to mine had during that period. She too had tried prescribed treatments with little success. I prepared a Plantain-based salve for her. Months later she returned, eager to show me the improvement. It was a reminder that sometimes the most overlooked plants can leave the deepest impression.

Do you have Ribwort Plantain or Broadleaf Plantain growing in your garden? Have you ever used it traditionally? I’d love to hear your experiences in the comments below.

I hope you feel inspired. Look after your body, and it will keep you healthy.

Always Tense? The Forgotten Herb Our Grandparents Used for Stress, Headaches and Digestion

The Herb That Once Had a Remedy for Everything

There are some plants that quietly occupy our gardens without asking for attention.

Betony is not flashy. It does not produce enormous blooms or dramatic colours. Yet for centuries it was considered one of the most respected medicinal plants in Europe.

The old herbalists held Betony in such high regard that a common saying emerged:

“Sell your coat and buy Betony.”

While that may sound excessive today, it reflects the esteem in which this humble member of the mint family was once held.

Today, Betony is largely forgotten.

Yet it continues to grow faithfully in gardens, meadows and hedgerows, offering the same gentle qualities that made it a favourite of generations past.

By Dr Catherine W Dunne MSc.D | M.H.I.T. | Registered Nurse

Meeting Betony

Betony (Stachys officinalis) is a perennial herb belonging to the mint family (Lamiaceae).

It produces upright square stems crowned with whorls of deep pink-purple flowers that bloom through summer.

The leaves

form attractive basal clumps and are softly textured, with a slightly crinkled appearance and finely toothed margins.

Like many members of the mint family, Betony is a valuable plant for pollinators. Bees seem particularly fond of its flowers, and on warm summer days the flower spikes can be alive with activity.

In my own garden, the bees arrive almost as soon as the flowers open.

A Long History of Traditional Use

Betony has an impressive herbal history stretching back to Ancient Rome and Medieval Europe.

Traditional herbal texts describe its use for:

  • Headaches
  • Nervous tension
  • Stress and anxiety
  • Digestive discomfort
  • General weakness and fatigue
  • Minor wounds and bruises

In medieval monasteries it was considered one of the essential medicinal herbs to cultivate.

Many herbal traditions regarded Betony as both a physical and emotional tonic—supporting the body while also helping to calm an overworked mind.

What Modern Herbalists Appreciate

Modern herbalists tend to view Betony as a gentle nervine and restorative herb.

Traditionally it has been used to:

  • Encourage relaxation
  • Ease tension headaches
  • Support nervous system balance
  • Promote a sense of calm during periods of stress
  • Aid recovery during convalescence

Its action is generally considered mild rather than dramatic.

Betony is not the herb that forces change.

Instead, it works quietly in the background, helping the body find its own equilibrium.

Harvesting Betony

The aerial parts of the plant are usually gathered while flowering.

Both leaves and flowering tops can be used.

Fresh material may be tinctured, while dried herb can be prepared as a tea.

This year, my own Betony patch has flourished, producing a beautiful display of flower spikes and providing plenty of material for winter stores.

Some will be dried carefully for teas.

Some will find its way into tinctures.

And some may eventually become part of infused oils and herbal preparations.

This year my Betony has been one of the stars of the garden. The bees seem to adore it, and its flower spikes have provided colour for weeks. As I gathered some for drying, I found myself reflecting on how many generations before us would have recognised this plant immediately.

Why I Grow It

Part of the joy of growing herbs is reconnecting with plants that previous generations knew intimately.

Many of these herbs have slipped quietly from common awareness, replaced by newer remedies and modern conveniences.

Yet Betony remains exactly as it has always been.

Reliable.
Beautiful.
Bee-friendly.
And steeped in centuries of herbal tradition.

Perhaps that is why it continues to earn a place in my garden.

Not because it shouts for attention.

But because, like many of the best herbs, it simply gets on with the job.

Have you ever grown Betony in your garden, or encountered it in the wild? I’d love to hear about your experiences in the comments below.

I hope you feel inspired. Look after your body, and it will keep you healthy.

Self Heal (Prunella vulgaris): The Humble Lawn Herb with Extraordinary Potential

Walk through almost any wildflower meadow or unmown lawn in Ireland during summer and you may find a small purple flower quietly growing beneath your feet. Known as Self Heal, Heal-All, or Carpenter’s Herb, Prunella vulgaris has earned a reputation over centuries as one of nature’s most versatile healing plants.

Despite its modest appearance, Self Heal has been valued in traditional European, Chinese, and Native American herbal medicine for generations.

By Dr Catherine W Dunne MSc.D | M.H.I.T. | Registered Nurse

A Plant with a Long History

The common name “Self Heal” reflects the herb’s traditional reputation for supporting the body’s natural restorative processes. Historically, it was used both internally and externally for wounds, sore throats, digestive complaints, and periods of convalescence following illness.

Traditional herbalists often regarded Self Heal as a herb that helped restore balance when the body was under stress or recovering from physical challenges.

Modern Interest in Prunella

Modern research has identified a range of naturally occurring compounds within Prunella, including:

  • Rosmarinic acid
  • Flavonoids
  • Tannins
  • Triterpenes
  • Polysaccharides

These compounds are being studied for their antioxidant, soothing, and immune-supportive properties.

While research continues, traditional use remains one of the strongest guides to understanding this remarkable plant.

How to Recognise Self Heal

Self Heal belongs to the mint family (Lamiaceae), a large family of plants that includes familiar herbs such as Mint, Thyme, Sage, Lemon Balm, Rosemary, Betony, Ground Ivy and Dead Nettle. While many mint-family plants are aromatic, others such as Self Heal and Dead Nettle have little noticeable scent but still display the family’s characteristic square stems and opposite leaves.

Like many members of the mint family, Self Heal displays several distinctive characteristics:

  • A square stem rather than a round stem
  • Opposite pairs of leaves growing directly across from each other
  • Fine hairs on the stems and leaves
  • Purple or reddish tinges on stems and flower bracts
  • Dense flower heads formed from stacked bracts

The flowers are typically blue-violet to purple and emerge from a compact, cone-like flowering head. As the flowers open, they appear in rings around the flower spike, creating the distinctive appearance that makes Self Heal easy to recognise once in bloom.

The leaves are oval to lance-shaped with gently toothed margins and are usually slightly hairy. Young plants can look quite different from mature flowering specimens, often appearing as low-growing clusters of leaves before sending up flowering stems.

Self Heal commonly grows in lawns, meadows, field margins, pathways, and other grassy areas throughout Ireland. It often thrives where mowing is infrequent, creating beautiful patches of purple flowers during summer.

Once you learn to recognise the square stems, opposite leaves, and distinctive flower heads, you may be surprised to discover how often Self Heal has been growing unnoticed beneath your feet.

Self Heal as a Tea

One of the simplest ways to use Self Heal is as an herbal tea.

Traditionally enjoyed for:

  • Sore throats and hoarseness
  • Mouth and gum comfort
  • Digestive upset
  • Seasonal wellness
  • General convalescence and recovery

The dried flowering tops and leaves make a mild, pleasant tea that combines well with:

  • Plantain
  • Betony
  • Lemon Balm
  • Meadowsweet
  • Thyme

For many herbalists, Self Heal tea is a valuable addition to the winter medicine cupboard.

Self Heal as a Tincture

Fresh or dried flowering tops can be extracted in alcohol to create a tincture.

Traditional uses include:

  • Supporting normal immune function
  • Swollen glands and throat discomfort
  • Seasonal challenges
  • General constitutional support

A tincture offers a concentrated preparation and provides a convenient way to use the herb throughout the year.

Self Heal in Vinegars and Oxymels

Self Heal No photo description available.combines beautifully with apple cider vinegar and honey.

An oxymel containing Self Heal, Thyme, Plantain, and seasonal herbs has traditionally been used to support:

  • Winter wellness
  • Throat comfort
  • Respiratory health
  • Family immune support

The addition of honey makes this preparation especially suitable for children and those who dislike herbal teas.

External Uses

Traditionally, Self Heal was used externally as:

  • A wash for minor skin irritations
  • A compress for cuts and abrasions
  • A soothing rinse for the mouth and throat

These uses contributed greatly to the herb’s reputation as a “heal-all” plant.

Harvesting Self Heal

The best time to harvest Self Heal is when the flower heads are fully developed and actively flowering.

Harvest on a dry day after the morning dew has evaporated.

The flowering tops can be:

  • Dried for tea
  • Tinctured fresh
  • Added to vinegars
  • Used in oxymels
  • Infused into oils

Self Heal for Hoarseness, Reflux and Recovery

One of the most interesting modern uses of Self Heal may be in supporting irritated tissues of the mouth, throat, and upper digestive tract.

Many people experience symptoms such as:

  • Persistent throat clearing
  • Hoarseness
  • A burning sensation behind the breastbone
  • A feeling of throat irritation despite normal investigations
  • Lingering throat sensitivity following viral illnesses

Traditionally, herbalists often turned to soothing and restorative herbs when tissues appeared irritated or inflamed.

Self Heal combines particularly well with:

  • Plantain (Plantago spp.)
  • Betony (Stachys officinalis)
  • Thyme (Thymus vulgaris)

Together these herbs create a gentle tea traditionally used to support throat comfort and general respiratory wellbeing.

While Self Heal is not a replacement for medical assessment or prescribed treatment, many people find herbal teas containing these plants offer a soothing and supportive addition to their overall care plan.

Traditionally, Self Heal has also been valued as a restorative herb during periods of convalescence, particularly when the throat, mouth, or upper digestive tract remain sensitive following illness.

Why Self Heal Has Earned a Place in My Herbal Garden

Over recent years, Self Heal has become one of the herbs I reach for most often. Although frequently overlooked as a common lawn flower, I have found it combines beautifully with Plantain, Betony and Thyme in teas intended to support throat comfort, hoarseness and seasonal wellness.

Each summer I harvest and dry the flowering tops for use throughout the winter months. It is one of the simplest, most accessible, and most versatile herbs growing naturally in the Irish landscape.

Sometimes the most valuable remedies are not found in distant rainforests or exotic mountain ranges. Sometimes they are growing quietly beneath our feet.

A Final Thought

In an age where many people search for exotic herbs from distant countries, Self Heal reminds us that some of the most valuable plants may already be growing beneath our feet.

Small, resilient, and quietly powerful, Prunella vulgaris continues to live up to its ancient reputation as one of nature’s most trusted herbal allies.

I hope you feel inspired. Look after your body, and it will keep you healthy.

Cancer, Sugar, Carbohydrates and Iron – Why Metabolism is Receiving Greater Attention Today

Many people today are asking whether nutrition, metabolism, chronic inflammation and certain plant compounds may play a role in the development or growth of cancer. Topics such as high sugar intake, heavily processed carbohydrates, iron metabolism and medicinal plants are increasingly being discussed, both within modern research and integrative health approaches.

Science is showing more and more clearly that cancer is not solely a genetic disease, but may also be closely connected to metabolic processes, inflammation, hormonal changes and the overall health of the body.

At the same time, interest is growing in traditional medicinal plants such as Artemisinin (Artemisia annua), Prunella vulgaris and Sutherlandia frutescens, whose compounds have shown possible supportive properties in laboratory studies.

However, one important point remains:

This article is not intended as a cure claim or a replacement for medical treatment. Rather, it aims to bring together current scientific understanding, traditional plant knowledge and holistic health perspectives in a clear and understandable way.

Because sometimes health begins not only with the question:

“How do we fight disease?”

but also with:

“How do we strengthen the person?”

By Dr Catherine W. Dunne, MSc.D., RGN (GPN)
Holistic Healthcare Wexford | Co-founder, Aumvedas Academy

In recent years, researchers have become increasingly interested in why certain metabolic states may influence the growth of cancer cells.

Particular attention has been given to:

  • elevated blood glucose levels
  • diets high in processed carbohydrates
  • chronically raised insulin levels
  • changes in iron metabolism

It is important to understand that the human body requires both glucose and iron for survival. The brain, muscles, immune system and virtually every cell in the body depend upon them. Nevertheless, many studies suggest that cancer cells often “exploit” these systems more aggressively in order to grow rapidly.

The Relationship Between Cancer and Sugar

Many cancer cells consume significantly more glucose than normal cells. This phenomenon has been recognised in oncology for many years and is even the basis of modern PET scans, where radioactive glucose is used to identify metabolically active tumours.

One well-known concept related to this is the so-called Warburg effect, in which cancer cells often favour rapid sugar metabolism (glycolysis) even when oxygen is available.

This does not mean:

“Sugar automatically causes cancer”
or
“Cancer can simply be starved.”

Human metabolism is far more complex than that.

Even during very low-carbohydrate diets, the body continues to produce glucose because it is essential for vital functions.

What may matter more is the overall metabolic environment:

  • chronically elevated insulin levels
  • insulin resistance
  • obesity
  • visceral abdominal fat
  • inflammatory processes
  • lack of movement
  • chronic stress
  • highly processed foods

Particularly problematic are often:

  • refined sugars
  • heavily processed carbohydrates
  • constant snacking
  • sugary drinks
  • ultra-processed foods

Over time, these factors may contribute to chronic inflammation and hormonal imbalance.

Interestingly, chronic stress itself can raise blood glucose levels because cortisol stimulates glucose release from the liver. In other words, the body may remain in a prolonged “high-glucose state” even without excessive sugar intake.

Cancer and Iron – An Often Overlooked Connection

Iron also plays an important role in relation to cancer.

Iron is essential for:

  • cell division
  • oxygen transport
  • energy production
  • DNA synthesis
  • mitochondrial function

Because cancer cells divide rapidly, they often require large amounts of it.

Some tumour types even increase iron uptake into their cells. Researchers have therefore observed altered iron metabolism in several cancers, including breast, bowel and liver cancers.

However, too much free iron may also become problematic.

It can promote oxidative stress and generate free radicals capable of damaging cellular structures and DNA.

Particularly interesting is the fact that after menopause, iron levels naturally rise in many women because monthly blood loss stops. At the same time, inflammation, metabolic dysfunction and hormonal changes often increase.

This does not automatically indicate danger.

However, it helps explain why researchers are paying closer attention to:

  • ferritin levels
  • chronic inflammation
  • metabolic health
  • liver health
  • insulin resistance

Ferritin Is Not Just “Iron”

An important point:

Ferritin is often viewed simply as an iron marker. In reality, ferritin is also an inflammatory marker.

Elevated ferritin levels may occur in:

  • chronic inflammation
  • fatty liver disease
  • infections
  • alcohol burden
  • metabolic syndrome
  • autoimmune disease
  • cancer processes

This is why ferritin should always be interpreted within the wider clinical picture.

The Modern Perspective

Modern research increasingly views cancer as a metabolic disease as well as a genetic one.

This does not mean that sugar or iron alone “cause” cancer.

Rather, a chronically inflamed and metabolically stressed environment may support the growth of already-damaged cells.

For this reason, many integrative approaches today focus on:

  • stable blood sugar regulation
  • reducing heavily processed foods
  • regular movement
  • maintaining healthy muscle mass
  • good sleep
  • stress reduction
  • anti-inflammatory nutrition
  • supporting mitochondrial health

The goal is not fear —
but a better understanding of how deeply nutrition, metabolism, hormones and long-term health are interconnected.

Or more simply:

The body needs sugar and iron to survive.

But when metabolic systems become dysregulated, those same systems may also be exploited by cancer cells.

Possible Supportive Plant Compounds: Artemisinin and Prunella vulgaris

Alongside nutrition, metabolism and inflammation, researchers are increasingly interested in certain plant compounds that may potentially influence the growth or spread of cancer cells.

However, it is important to state clearly:

Many of these approaches remain within the realm of laboratory research, animal models or early experimental studies. They are not currently scientifically confirmed cancer cures.

Nevertheless, there are some interesting observations.

Artemisinin – Originally Known from Malaria Treatment

Artemisinin is derived from the plant Artemisia annua and first became known through malaria treatment.

What made Artemisinin particularly interesting in cancer research was its relationship with iron.

Cancer cells often contain elevated iron levels and increased iron metabolism. Artemisinin reacts with iron and may generate free radicals capable of damaging cancer cells more strongly than healthy cells.

This mechanism attracted significant scientific attention.

Laboratory studies have shown indications of:

  • slowed tumour growth
  • inhibition of cell division
  • promotion of apoptosis (programmed cell death)
  • possible reduction of metastatic activity

Research has included:

  • breast cancer
  • bowel cancer
  • leukaemias
  • prostate cancer
  • lung cancer

Artemisinin is particularly discussed today in relation to:

  • oxidative stress within cancer cells
  • mitochondrial changes
  • iron-dependent metabolic processes

Nevertheless:

Large-scale human clinical trials confirming Artemisinin as a cancer treatment are still lacking.

Therefore, it should never be viewed as a replacement for oncology care, but rather as a possible supportive research avenue within integrative approaches.

Prunella vulgaris – Self-Heal

Prunella vulgaris, also known as Self-Heal, has been traditionally used for centuries for inflammatory swellings, lymphatic congestion and “lumps.”

Modern studies suggest that certain plant compounds may possess possible anti-cancer properties.

These include:

  • rosmarinic acid
  • ursolic acid
  • flavonoids
  • triterpenes
  • polysaccharides

Laboratory findings have suggested:

  • inhibition of breast cancer cell growth
  • possible reduction in cell migration and metastasis
  • anti-inflammatory effects
  • immune-supportive actions
  • promotion of programmed tumour cell death

Interestingly, Prunella vulgaris was historically used long before modern medicine for “breast lumps” and glandular swellings.

Again, however, the evidence currently comes mainly from:

  • cell culture studies
  • animal models
  • early experimental research

There is currently no scientifically confirmed evidence that it cures cancer in humans.

Integrative Support Rather Than False Cure Claims

Modern integrative research is increasingly exploring how:

  • metabolism
  • inflammation
  • immune function
  • mitochondrial health
  • iron metabolism
  • nutrition
    and plant compounds

may interact together.

The focus is less on “miracle cures” and more on the question:

How can the body be supported in a way that is less inflammatory and less metabolically burdensome?

For this reason, many people now also seek support through:

  • anti-inflammatory nutrition
  • stable blood sugar balance
  • stress reduction
  • sleep optimisation
  • movement
  • holistic support
  • plant-based compounds

while conventional medical treatment continues to play a central role.

Because modern research continues to show one thing above all:

The human body is far more complex than simple headlines suggest.

Sutherlandia frutescens – The South African “Cancer Bush”

Another plant attracting increasing interest in integrative research is Sutherlandia frutescens.

Native to South Africa, it is traditionally known as:

  • Cancer Bush
  • Balloon Pea
  • Kankerbos

For centuries it has been used within traditional African herbal medicine to support:

  • chronic illness
  • exhaustion and weakness
  • inflammation
  • stress burden
  • weight loss and wasting
  • weakened immunity

Researchers became interested after laboratory studies suggested possible:

  • antiproliferative effects
  • antioxidant properties
  • immune-modulating actions
  • anti-inflammatory mechanisms

Investigated compounds include:

  • L-canavanine
  • pinitol
  • GABA
  • flavonoids
  • triterpenoids

Some experimental studies suggest that Sutherlandia frutescens may potentially influence the growth of certain cancer cells.

At the same time, the plant was traditionally viewed less as a “tumour destroyer” and more as a strengthening support herb during severe illness.

Many traditional healing systems followed this same philosophy:

Not only treating disease itself —
but supporting the whole person:

  • strength
  • appetite
  • sleep
  • stress regulation
  • immune function
  • overall resilience

Again, it is important to state clearly:

There is currently no scientifically confirmed evidence that Sutherlandia frutescens cures cancer in humans.

It should therefore never replace medical diagnosis or oncology treatment.

Nevertheless, modern research continues exploring how traditional medicinal plants may potentially:

  • modulate inflammation
  • influence oxidative stress
  • support immune function
  • alter metabolic processes within cancer cells

This connection between traditional plant wisdom and modern metabolic research is opening increasingly interesting questions within integrative medicine.

I hope you feel inspired. Look after your body, and it will keep you healthy.

Cleavers: The Herb You’re Probably Cutting Down Without Realising

By Dr Catherine W. Dunne, MSc.D., RGN (GPN)
Holistic Healthcare Wexford | Co-founder, Aumvedas Academy

At this time of year, cleavers starts appearing everywhere. It weaves its way through hedgerows, climbs over other plants, and sticks to your clothes as you pass.

Most people know it as “that clingy weed” and cut it back without a second thought.

It’s a pity – because it’s one of the most useful seasonal herbs growing right outside the door.

Cleavers (Galium aparine) has a long history of traditional use, particularly in supporting the lymphatic and urinary systems. While modern research is still developing, there is enough evidence, combined with long-standing herbal practice, to show it has a valuable role when used correctly.

What Cleavers Supports

Cleavers is best known for its effect on fluid movement in the body.

It supports the lymphatic system, which plays a key role in immune function and waste removal. When this system becomes sluggish, people may notice swollen glands, fluid retention, or a general sense of heaviness.

Cleavers helps restore movement. It works gently, without forcing the body, making it suitable for ongoing use over a period of time.

There is also a clear link between lymphatic congestion and skin health. Conditions such as eczema, acne, and psoriasis can sometimes reflect what is happening internally. Supporting lymphatic flow may help improve these from the inside out.

In addition, cleavers has mild diuretic properties, helping the kidneys process and eliminate excess fluid. It is also recognised for its anti-inflammatory and antioxidant compounds, which contribute to its overall supportive role.

How to Use Cleavers

Fresh cleavers is always the best option when available.

A simple way to use it is as a tea. A handful of fresh herb can be infused in hot water and taken once or twice daily. It can also be prepared as a cold infusion, which preserves some of its more delicate constituents and is particularly suitable in warmer or more inflammatory conditions.

Cleavers can also be taken as a tincture. A few drops added to a warm herbal tea such as nettle or red clover is an easy and practical way to take it.

For those who prefer a stronger approach, fresh cleavers juice has traditionally been used in small amounts.

As with any herb, consistency matters more than intensity. Taken regularly over time, cleavers supports the body in restoring proper flow.

Cleavers Benefits:

Strong, consistent evidence:

  • Lymphatic support
  • Diuretic action
  • Skin link
  • Anti-inflammatory properties

Emerging / suggestive:

  • Immune modulation

A Simple Reminder:

Not everything useful comes in a bottle.

Sometimes the most effective support is already growing nearby – unnoticed and often removed before it’s ever given a chance.

Cleavers is one of those plants.

Moringa: Truth vs Hype

“Moringa tea won’t fix you – but it will quietly support you.”

Moringa has been called everything from a “miracle tree” to a “superfood powerhouse.”
And like most things that get that level of attention, the truth sits somewhere in the middle.

So let’s strip it back – no hype, no dismissal – just what actually matters.

By Dr Catherine W. Dunne, MSc.D., RGN (GPN)
Holistic Healthcare Wexford | Co-founder, Aumvedas Academy

Let us look at what generalised information is given to us, when we see their ads flashing past us on Social Media Posts:

Moringa oleifera is a plant with numerous health benefits that have withstood the test of time. The leaves have been utilized as food medicine for thousands of years. (There are, however, side-effects with the root and the bark (listed below), so avoid them.)

Moringa leaves and flowers were first discovered around 2,000 BC in northern India where traditional physicians quickly became aware of the therapeutic value. As a result of the leave’s high levels of valuable nutrients, moringa was diligently used by members of royal families and other aristocrats.

Moringa, the “Miracle Tree” contains over 92 Nutritional Values – all in perfect balance!
Vitamins:
A (Alpha and Beta-Carotene), A B-Complex, C, D, E, K, Folate, Biotin, and many more.

Minerals:
Calcium, Chloride, Chromium, Copper, Fluorine, Iron, Manganese, Magnesium, Molybdenum, Phosphorus, Potassium, Sodium, Selenium, Sulphur, Zinc.

All 18 Amino Acids and many other beneficial nutrients, like Chlorophyll, Carotenoids, Flavonoids, Omega (3,6,9) Oils, Plant Sterols, Polyphenols, and still more.

While this sounds impressive, the presence of nutrients does not automatically translate into a therapeutic effect in the body.

Multiple studies show consuming moringa can improve blood sugar response. This is likely, at least in part, due to its fibre and protein content. This nutritional profile helps lower and level out blood sugar spikes. And balanced blood sugar is crucial for hormonal health, a healthy weight, and energy levels.

Antibacterial properties:
This plant produces substances to protect itself from bacteria in its environment. We receive these same antibacterial properties when we eat or apply it topically. In fact, in a 2011 study, researchers discovered that moringa extract inhibits the growth of S. aureus, V. parahaemolyticus, E. faecalis, and A. caviae.

Speeds healing:
Traditionally, many use moringa as a poultice to speed wound healing. We now have research to support that: Applying moringa to wounds can enhance wound healing. Moringa encourages blood clotting at the site of a wound. This shortens the time it takes to repair damage and speeds wound healing time.

Facilitates sleep:
As a protein-rich food, moringa packs an assortment of amino acids, some of which (most notably tryptophan) are the backbone of sleep-inducing hormones, like melatonin, priming the body for improved and more restful sleep.

Lowers cholesterol:
Moringa may also lower cholesterol, thanks to high levels of fibre and plant sterols. In a rabbit study, it lowered cholesterol and reduced plaque in the arteries as effectively as medication, without the side-effects.

Reduces severity of asthma:
In one of the few human clinical trials on the plant, adults with asthma took 3 grams of moringa twice daily (added to food) for three weeks. Moringa not only reduced asthma symptoms, but also reduced the severity of asthma attacks.

Reduces inflammation:
As with all plant-based foods, a number of studies show moringa contains phytochemicals that act as anti-inflammatories. Because inflammation is at the root of many diseases, the plant may help protect the body from long-term issues like arthritis, Crohn’s disease, and even chronic pain. (https://pmc.ncbi.nlm.nih.gov/articles/PMC9916933/)

This PubMed study states: “While the entire tree has antitumor activity, the sex hormone-related property is attributable to its ROOT, folk medicine use has also proven.” (I hear the root has been used as an abortifacent in India).
“This plant has been studied in relation to diabetes and thyroid function.” (https://pmc.ncbi.nlm.nih.gov/articles/PMC12003216/)

Moringa: Truth vs Hype

What Moringa Actually Is

Moringa (Moringa oleifera) is a leafy plant traditionally used as both food and medicine, particularly in parts of India and Africa.

The leaves are the part most commonly used and importantly, the safest.

They contain:

  • Plant protein
  • Minerals like calcium, iron, and magnesium
  • Vitamins (especially beta-carotene and vitamin C)
  • Antioxidants such as quercetin and chlorogenic acid

👉 In simple terms:
It’s a very nutrient-dense green.

Where the Hype Comes From

You’ll often see claims like:

  • lowers blood sugar
  • reduces cholesterol
  • boosts immunity
  • aids weight loss
  • supports brain health

Now, here’s the important part:

👉 Most of these claims come from:

  • small studies
  • animal research
  • or early-stage trials

That doesn’t make them false, but it does mean they are not strong enough to stand as treatments.

What Moringa Can Genuinely Do

When you remove the exaggeration, moringa sits in a very useful place:

1. Nutritional Support

It can help in:

  • fatigue
  • recovery
  • low nutrient intake

Think of it as:
👉 “filling in the gaps” rather than correcting disease

2. Antioxidant Support

Its plant compounds help:

  • reduce oxidative stress
  • support the body’s natural repair processes

Not dramatic — but quietly helpful over time.

3. Gentle Metabolic Support

There is some evidence it may:

  • support blood sugar balance
  • assist lipid (cholesterol) profiles

But:
👉 this is supportive, not therapeutic

What It Does NOT Do

Let’s be clear — because this is where people get misled.

Moringa does not:

  • treat diabetes
  • replace cholesterol medication
  • cause weight loss
  • “boost” immunity in any direct way

If something claims to do all of the above…

👉 it’s being oversold.

Who It May Suit

Moringa tea or powder can be useful for:

  • people feeling run down or depleted
  • those recovering from illness
  • general nutritional support
  • mild inflammatory states

It fits best as part of:
👉 a wider approach — not a standalone solution

Safety – What You Need to Know

  • Use leaf only (avoid root and bark)
  • Avoid in pregnancy as a precaution
  • Be mindful if taking:
    • diabetes medication
    • blood pressure medication
    • thyroid medication

As always:
👉 more is not better

How to Use It

Simple and effective:

  • Tea:
    1 teaspoon dried leaf
    Steep 5–7 minutes
  • Powder:
    Add to smoothies, soups, or food

👉 Consistency matters more than dose.

Final Thought

Moringa doesn’t need exaggeration.

It’s not a miracle.
It’s not a cure.

But it is:

👉 a steady, supportive plant that earns its place quietly

And in a world full of noise…

that’s often exactly what the body needs.

I hope you feel inspired. Look after your body, and it will keep you healthy.

How Healthy Are “Zero” Soda Drinks?

Practitioner of Plant and Herb Medicine and licensed Nurse.

Fanta Zero, Coca-Cola Zero, 7-Up Free, Sprite Zero, Lucozade Zero, Pepsi Max and their likes. Here is a little research I have done for you.

I am looking at the health impact of Zero Diet Sodas and what damage they cause to our body.

“Zero” sodas are marketed as the healthier option because they contain no sugar, no calories, no guilt.
But does zero sugar really mean zero impact on health?

The short answer is no.

Let’s look at what’s actually inside these drinks and how they affect the body — particularly the kidneys, bones, metabolism, and gut.

What Are “Zero” Sodas?
“Zero” or diet sodas remove sugar and calories, replacing them with artificial sweeteners and acids to preserve sweetness and flavour.
They typically contain:

  • Carbonated water
  • Artificial sweeteners (most commonly aspartame, often combined with acesulfame-K)
  • Acids (citric acid or phosphoric acid)
  • Flavourings

They are called “Zero” because they contain no calories, not because they are biologically neutral.

Aspartame: The Ingredient Most People Don’t Question
Most Zero sodas contain aspartame.
Aspartame breaks down in the body into:

  • Phenylalanine
  • Aspartic acid
  • Small amounts of methanol

In occasional use, aspartame is generally tolerated by healthy adults.
Concerns arise with regular, long-term daily consumption.

Effects on the Kidneys
Large population studies consistently show that frequent diet soda consumption is associated with:

  • Faster decline in kidney function (eGFR)
  • Increased risk of chronic kidney disease
  • Higher rates of hypertension and metabolic stress

These effects are not caused by carbonation, but are likely related to:

  • Changes in gut microbiota
  • Increased oxidative stress
  • Insulin and blood-pressure dysregulation
  • Chronic low-grade inflammation

Plain sparkling water does not show these associations.

Effects on Bone Health
Many Zero sodas — particularly colas — still contain phosphoric acid.
High phosphorus intake without adequate calcium can:

  • Disrupt calcium balance
  • Increase calcium loss through urine
  • Reduce bone mineral density over time

Long-term diet soda consumption has been linked to lower bone density, especially in post-menopausal women.

Again, these effects are not seen with plain fizzy water.

Effects on Metabolism and Appetite
Despite being calorie-free, artificial sweeteners can:

  • Trigger insulin release in some individuals
  • Disrupt hunger and satiety signalling
  • Increase cravings for sweet foods later
  • Alter dopamine reward pathways

In practice, many people who consume diet sodas regularly do not lose weight, and some gain weight over time.

The body does not like being tricked.

Effects on Gut Health
Artificial sweeteners can alter gut bacteria, leading to:

  • Reduced glucose tolerance
  • Increased inflammatory signalling
  • Impaired mineral absorption

Gut health plays a direct role in kidney health, bone health, and metabolic balance.

What “Zero” Sodas Are — and Are Not

✔ Better than sugar-sweetened sodas
✖ Not kidney-protective
✖ Not bone-supportive
✖ Not metabolically neutral

They remove sugar, not physiological consequences.

Who Should Be Especially Careful?
This is something no General Practitioner (GP)/Family Doctor or Hospital Consultant tells you.
Regular consumption of Zero sodas is best avoided in people with:

  • Kidney disease or reduced kidney function
  • Hypertension
  • Osteopenia or osteoporosis
  • Diabetes or insulin resistance
  • Migraine disorders
  • Gut sensitivity or IBS

Healthier Alternatives
If you enjoy fizz:

  • Sparkling mineral water
  • Sparkling water with lemon or lime
  • Herbal iced teas
  • Kombucha (in moderation)

If you want sweetness:

  • Small amounts of real juice diluted with sparkling water – this is what I like doing.

The Bottom Line
Zero sodas are not toxic, but they are not health drinks.

An occasional one is unlikely to cause harm.
A daily habit over years is where issues quietly accumulate.

Zero calories does not mean zero impact.

I hope you feel inspired. Look after your body, and it will keep you healthy.
