Plants Used for Medicine by The Ancient Celts
Unlike the popular image often bestowed upon the Celts as a primitive, unruly people, they were actually quite an advanced and industrious society. They were traders in copper and tin, and they were one of the first peoples to meld the two precious metals into bronze—a craft in which they became masters, and very wealthy ones, at that.
The Celts of old were also a very holistic and spiritual people and it seems the opinion held of them by the majority today is an inaccurate and unfair one. This is due in large part to Hollywood often portraying them as a wild-eyed bunch of bloodthirsty warrior types who rush into battle waving their primitive weapons—with no idea of an actual battle plan or even an understanding of why or what they are fighting for. Their enemies in these films are often portrayed as more civilized and intelligent. However, modern knowledge of the Celts has shown that they were far from uncivilized.
The Celtics were a rural people by choice, preferring to live close to nature because of their love of the land and their view of themselves as being the caretakers of Mother Earth. The Druids were the spiritual guardians of the Celts and made sure that each Celtic citizen led a healthy, holistic lifestyle. Exercise and proper diet were important as was a healthy spirituality, reflected in the many festivals of the Celts. The Celtics practiced animism, a religious belief that all things contained a spirit: the water, trees, rocks, the land itself, and for this reason showed extra care towards nature, lest they grieve a spirit.
Trees, in particular, held a special place in Celtic religion, and they developed their alphabet around different trees. The Druids were also the shamans of the Celtics, the ancient "witchdoctors" and they used trees for medicine. In this article, I'll discuss some of the herbs used for medicine by the Celts. All are found in Ireland and are also found throughout the rest of Europe in varying quantities and regions, especially of course in Britain and Wales. This page is for information purposes only. I am not a qualified physician or herbalist, and any herbal treatments should be conducted under the supervision of a qualified and licensed herbalist or naturopath.
It’s easy to imagine the ancient Celts wandering through the forests or along the riverbanks and bogs of the south midlands of Ireland where Bilberry is abundant, gathering baskets of them to take back to their villages, munching handfuls of them as they delighted in their work. Places like Glenbarrow and the Slieve Bloom Mountains are excellent areas to experience this type of transportation back in time, where one can walk along nature trails and experience a glimpse of what life may have been like back then.
Among the natural remedies used by the Celts, Bilberry was probably one of the most beneficial and easiest to administer, as you merely have to chomp on a handful.
Otherwise known as Huckleberries or Whortleberries, Bilberries contain powerful antioxidants, protecting the venial and arterial walls from being populated by dangerous fats, and protecting veins from other damage. They are also believed to strengthen the blood-brain barrier, a membrane that separates the brain from the blood flowing around it. This prevents harmful substances thought to accelerate aging from reaching the brain and therefore helps to prevent debilitating diseases like Alzheimer's.
They are also very strong anti-cancer agents and contain anthocyanidins, a class of flavonoid, organic compounds widely distributed in higher plants; some are pigments and others have physiologic properties. These anthocyanins also protect our immune systems and have anti-histamine properties as well. Bilberries are also good for the skin, helping it to maintain its elasticity and tone. During the war, pilots ate bilberry jam before night missions to aid night vision.
It’s easy to use Bilberry to implement Bilberries into your diet by simply eating about a cup every day in a fruit salad, with your breakfast cereal, in a jam on toast, or as a delicious dessert. If you don't have or can't get Bilberries in your area, don't worry, Blueberries make a great substitute and have similar properties and health-giving benefits.
The Celts revered Bilberry so much that they celebrated their ripening with the Festival of Lughnasa which took place on the Sunday closest to the first day of August, and the harvesting of the berries was part of the celebrations. In some parts of Ireland, they still celebrate this festival as Fraochán Sunday.
Considered an invasive weed by many gardeners, Burdock was held in high esteem by the Celts who used it as a medicine and food, its roots being cooked as a vegetable or eaten raw. Unlike the gardeners of today, the Celts considered nothing as a weed and understood that every plant had its values and served a purpose.
Burdock has been found to be an excellent detoxifying herb due to its ability to stimulate the body to eliminate toxins. It triggers all of the excretory systems, lungs, liver, kidneys, sweat glands and lymphatic and urinary systems to expunge toxins and excess fluids, unblocking and detoxifying them.

The Druid shaman may have given Burdock root to pubescent teenagers suffering from acne, as it has been shown that Burdock improves this condition as well as eczema and psoriasis and also helps to regulate the hormonal system due to its containing plant sterols, which also have powerful cholesterol-lowering properties.
Burdock would also have been given to the elderly who suffered from arthritis, sciatica or gout. It is highly alkaline and anti-inflammatory and is used by herbalists today to treat these conditions. You can see why it would have been one of the major plants used for medicine by the Celts.
Burdock grows just about anywhere due to its resilience but prefers soil with high clay content. I have seen it growing near the South Lagoon at Sandymount Strand in the Clontarf Road area of Dublin. It's quite easy to use Burdock as a detoxifier, simply by making a tea of the roots, which are best harvested in July when they are at their peak medicinal value.
The natural habitat for Nettle would be Woodland and Pond areas as it naturally needs fertile soil, abundant sunlight and moisture to thrive. It wasn't until man first began cutting down the forests for his building projects that nettle began to grow elsewhere. Being a hardy plant that has survived, according to archaeologists several Ice ages, the Nettle has followed man around, and as we all know will make its home just about anywhere and everywhere. Who among us hasn't felt the sting of the Nettle as a kid!
What causes the stinging sensation of the Nettle is the penetration of our skin by the many needle-like hairs that cover the plant. This causes our immune system to releases histamine, a chemical found in some of the body's cells. The immune system mistakenly believes that this usually harmless substance is actually harmful to the body, and the histamine then acts on a person's eyes, nose, throat, lungs, skin, or gastrointestinal tract, causing allergy symptoms.
But the Nettle is significant among herbs used by the Celts in that it was probably one of the most widely used due to its ability to prevent hemorrhaging and stop bleeding from wounds. They would have used it to treat the wounds their warriors received in battle and also to help reduce excessive menstruation in the women.
Nettle also contains fibers which the ancient Celts would have likely used to make cloth for their clothing. Nettle was used to make cloth by the Germans during World War II when cotton was in short supply. Recently it has been found that lectin found in Nettles is useful in treating Prostate enlargement and is widely prescribed for this in our times.
Nettles also have a place in ancient Celtic folklore. Known as "Devil's Claw", Nettles were believed to indicate the living place of fairies, and their stings protected one from witchcraft or sorcery.
Mistletoe was most likely imported to Ireland via the Greeks, who traded with the Celts and exchanged medical knowledge with them. Reference to Mistletoe is strewn throughout Greek Mythology, the goddess Athene used it as a curative and Aeneas took it with him to the underworld in order to assure his safe return to the world above.
The Druids became great cultivators of Mistletoe, and can be found in Waterford today growing on old apple trees. The Celts had a special name for Mistletoe growing on apple trees, calling it silver bough, and it was considered sacred to the Celtic god Manannan, the sea god. It is now quite rare however, and can only be found in about a dozen places throughout Ireland today.
The Druids used Mistletoe in their celebrations of the festival of Alban Arthuan, held during the Winter Solstice around December 21st. The Greek writer Pliny mentions the Druids cutting Mistletoe on the new moon at the end of the Celtic year (around December 21st) and using it to decorate the oak trees surrounding they area where they would partake of the ceremonial meal. They would later use these Mistletoe boughs in conjunction with the sacrifice of a bull to appease the Oak God Hu, who they believed would impart sexual vigor to them.
Being hallucinogenic when consumed in large quantities, the Mistletoe berries were most likely used by the Druids in their rituals of prophesying and entering the "other worlds". Of all the natural remedies of the Celts, this was one of the most powerful.
In recent times Mistletoe has been investigated for its possible treatment of various cancers, and a drug named Iscador was developed by Rudolph Steiner and a team of physicians, pharmacists and scientists in the 1920s. Since then a plethora of Mistletoe-based drugs have been patented by various companies with names such as Plenosol, Helixor and Isorel.
Modern herbalists also use Mistletoe juice or tincture to treat cancer, however Mistletoe is extremely powerful, and I reiterate, should only be taken under the supervision of a qualified and licensed herbalist. Such precautions should be taken due to risk of toxicity as quoted below:
The Phoradendron species contain a toxin called phoratoxin, which can cause blurred vision, nausea, abdominal pain, diarrhea, blood pressure changes, and even death. The Viscum species of mistletoe contain a slightly different cocktail of chemicals, including the poisonous alkaloid tyramine, which produce essentially the same symptoms.
In April throughout Ireland beautiful fields of Dandelion can be seen growing in abundance. Dandelion is one of the most common wild plants found growing in Ireland, and around the world for that matter, and was another of the plants used for medicine by the ancient Celts. The ancient Celts celebrated February 1st as a festival to the White Goddess, whom Christianity later adopted and renamed St.Brigid, and one of her symbols was the Dandelion. The Celts would have used dandelion to treat fever such as malaria and jaundice as dandelion root stimulates the liver. This is supported by the 12th century medical text The Physicians of Myddfai and folk medicine records from CountyMeath in Ireland.
They may also have made Dandelion coffee from its roots, which they did in Counties Cork and Kerry during the Emergency years of WWII, and which is common among naturalists today.
Dandelion was later cultivated in medieval monasteries and was featured in the repertoire of natural medicines of the time. A tonic made from the sap and was taken at springtime as part of a rejuvenation and "spring cleaning" process. This would be in accord with the practices of the ancient Celts who were very much in tune with the cycles of nature.
Dandelion is today used as a great detoxifier, blood cleanser and digestive aid. It strengthens the liver and aids it in breaking down toxins and it also stimulates the kidneys in order for the toxins to be eliminated rapidly. The flow of bile into the intestine stimulated by Dandelion enables better digestion and prevents the formation of gallstones.
In the Turraun bogs of Co. Offaly lies the water-loving Willow, another of the herbs used for medicine by the ancient Celts. The Willow was sacred to the Celts, representing the month from the 18th of March to the 15th of April on the Celtic calendar, and may have been used by the Celts to combat rheumatism, common in the dampness of the bog areas. Willow was also sacred to the Moon goddess Arduinna and the Druid god Beli.
Acetyl salicylic acid, derived from the bark of the Willow, has perhaps been used by us all at one time or another. It is commonly known today as aspirin!
The common mode of administering Willow bark for anti-inflammatory conditions by herbalists is in a tea, several grams of the bark being boiled in a pint of water and administered about 3 times per day. Always consult a specialist before ingesting a medicinal remedy.
Comfrey (Lus na Cnámh Briste)
The Gaelic name for Comfrey means "the plant for broken bones," and is used as a poultice today for treating sprains, sprains, bruises and swellings. Until recently it was used by families in the Aran Islands, Kerry, Limerick and other parts of the country as a poultice for healing broken bones, knowledge which has probably been passed up through the generations from the ancient Celts. Comfrey can be found growing along the river at Shanganagh and near Loghlinstown, and in the past, in parts of Co Louth along the river Boyne.
Due to their active lifestyle and the Druids being master botanists and herbalists, it would have been stable in the Celtic medicine chest. Comfrey is perennial; it grows year round and would have been widely available to Celtic physicians. The astringent properties of Comfrey make it effective in stopping internal hemorrhage, and it is taken in a decoction to do so.
There has been some controversy about the toxicity of Ccomfrey as mentioned by a reader in the comments. This statement has been removed as the controversy is ongoing and nothing has been proven.
Comfrey is prolific in terms of its effects in promoting rapid healing of tissues, and would have been used regularly to treat open wounds and injuries. In 2002, the F.D.A. advised against ingestion of comfrey due to toxicity and the potential for serious side effects.

I just love "experts", they know everything, everything there is to know and know nothing. If one is in touch with OneSelf as are the Druids (Shaman) One Knows, as Knowing is not of one's personal expert self, Knowing Is and this is what One Knows. An expert is an intellectual in denial of OneSelf and out of touch with Nature all around, so can only speak from a book or "credits", where those credits are a credible acknowledgement of fellow intellectual bookworms.
Knowing comes first, the details come later.

I'm researching Irish herbs so appreciate you posting information on Irish Herbs but as Joe commented 2 months ago your resources are not cited and that would have been so helpful. I'm currently studying Advanced Herbalism at the Colorado School of Clinical Herbalism.
Joe on October 23, 2013:
Hello there, I know that I am a few years late but I hope you will still see my comment. I am studying Medicnial Botany, and I'm currently researching the Celtic medicine traditions of Ireland and Scotland for paper. I thank you for your very informative article, I was just wondering if you could provide any of the sources where you found this information so I can do further investigation. Thanks again!

Your comment re Viscum Album that it is highly toxic is incorrect. As a Medical Herbalist I can legally use Viscum in Britain and also in the occupied territory of the Six Counties of Northern Ireland.
Also re comfrey, the socalled scientific basis for claiming that it too is highly toxic is based on evidence that has no relevance to it's actual medical use . While you acknowledge that people should consult a herbalist , there are many levels of competence among those that are trained as herbalists in Ireland. Your comments on the herbs overall then scares people off and makes our job as professional medical herbalists more difficult . So , I would suggest that before you publicise information on herbs that you present a more balanced picture.
The Irish Institute of Medical Herbalists (IIMH) and it's members are the professional practitioners of herbal medicine and can give you help and guidance on such matters . My text is critical but I am grateful that there are people like you to help promote the cause of herbal medicine. Thank you . Emmett Walsh
