What is it?

It is the very astringent and bitter bark of the Willow that has been historically used in herbal medicine. Willow is of course the well-known tree found in many parks and gardens. Willow’s graceful drooping branches give it a sweetly melancholic appearance; ‘the weeping willows’.

How has it been used?

Willow branches are more pliable and less likely to split than most types of wood and so it has been used since the earliest civilisations for making baskets, fish traps, items of wicker and even the framing of homes.

It is certain that Willow bark and leaves were also widely used as a natural anti-inflammatory treatment for many thousands of years throughout our history. White Willow grew on the banks of the river Nile and the ancient Egyptians saw the weeping Willow as a symbol of joy! The 110 pages of the Ebers Papyrus, dated to 1534 BC lists over 700 herbal remedies but the most important plant species is tjeret or salix, known today as Willow. The Ebers papyrus describes the use of Willow as a general-purpose tonic and as an anti-inflammatory pain reliever for aches and pains.

The Physicians in ancient China used White Willow bark to relieve pain and the ancient Greek physician Dioscorides wrote of its power to ease inflammation. Thomas Bartram describes how Willow Bark combined with Celery Seed and Black Cohosh can help treat rheumatoid arthritis.

King's Dispensatory writes 'Willow bark is tonic, antiperiodic, and an astringent bitter. It has been given in intermittent dyspepsia, connected with debility of the digestive organs, passive haemorrhages, chronic mucous discharges, in convalescence from acute diseases, and in worms. In chronic diarrhoea and dysentery, the tonic and astringent combination of the willow renders it very eligible. It may be given in substance, in doses of 1 drachm of the powder, repeated as indicated; or of the decoction, 1 or 2 fluid ounces, 4 or 5 times a day. The decoction has also proved efficient as a local application to foul and indolent ulcers'

Pain and inflammation are reliably reduced if sufficient amounts of Willow are taken so it was the subject of early scientific enquiry. In 1828 the French chemist Henri Leroux was the first to isolate one of the ingredients in Willow that was able to treat pain and inflammation; salicin. A small amount of it was as effective as a much larger dose of the crude herb but it caused such terrible stomach aches that it wasn’t for another 70 years when the German chemist Felix Hoffmann developed salicin into the much more digestible acetylsalicylic acid that the drug started to achieve the fame that it continues to enjoy to this day. Hoffmann’s employer; the now-giant pharmaceutical company Bayer, called this new substance aspirin.

Science on Willow Bark

~ There is a great deal more to Willow Bark than just the chemicals in it that act as the precursors to aspirin. Modern studies have led to some intriguing insights into Willow that suggest that it is constituents such as its flavonoids and polyphenols that are the real reason why it can be so helpful for painful mobility disorders such as back pain and arthritis.

~ Traditionally, willow bark has been used as an analgesic, and many clinicians have evaluated the effectiveness of white willow bark in the treatment of chronic lower back pain of unknown origin. Willow bark has been compared to placebo and to cyclooxygenase-2 inhibitors, and many of the studies found willow bark to be as effective or superior to other methods (Chrubasik S, Eisenberg E, Balan E, et al. Treatment of low back pain exacerbations with willow bark extract: a randomized double-blind study. Am J Med 2000;109:9-14) (Chrubasik S, Kunzel O, Model A, et al. Treatment of low back pain with a herbal or synthetic anti-rheumatic: a randomized controlled study. Willow bark extract for low back pain. Rheumatology (Oxford) 2001;40:1388-93)

~ Willow bark is a traditional analgesic therapy for osteoarthritis. The benefits of willow bark extract on patients that suffer from osteoarthritis have been studied in several trials. All treatment groups were compared to placebo to establish effectiveness. All studies showed a significant difference between willow bark extract and placebo in the treatment of chronic pain (Schmid B, Ludtke R, Selbmann HK, et al. Efficacy and tolerability of a standardized willow bark extract in patients with osteoarthritis: randomized placebo-controlled, double blind clinical trial. Phytother Res 2001;15:344-50) (Mills SY, Jacoby RK, Chacksfield M, Willoughby M. Effect of a proprietary herbal medicine on the relief of chronic arthritic pain: a double-blind study. Br J Rheumatol 1996;35:874-8)

Safety of Willow Bark

Unlike aspirin It is pretty much impossible to do harm with high doses of Willow Bark because to reach the levels that would equate to a toxic level of salicylates you would need to take in over half a kilo of Willow Bark a day, which would be virtually impossible however much you tried to!

That said Willow bark should be avoided whilst breast-feeding so as not to pass extra salicylates on to an infant who may then go on to develop a sensitivity to them. There are no known issues with using Willow in pregnancy and in most cases it will be tolerated fine by the young or old.

General safety note on herbs

Therapeutic substances, and this certainly all includes all medicinal herbs, can do good and, therefore, also have the potential to do harm. The maxim that 'the poison is in the dose' precisely describes how too much of anything can be bad for us and the ancient rule to 'firstly, do no harm is, to this day, held as the core directive by all practitioners of traditional herbal medicine. So, not only are we careful to do our best to use the right herbs but, equally, we take care to not give too much of them or use them overlong.

For some years now, against this old, proven and safe way of herbalism, there has been a rising tide of excessive caution and scare-mongering in many parts of the world. The same authorities and medical publications that no so long ago decried herbal medicines as ineffectual have now taken up a different kind of adversarial position. That they are dangerous substances that should not be taken for a long list of reasons and really should only be prescribed by Doctors, who of course have zero training in them.

Lists of '10 popular herbs and why you should avoid them' include things like Garlic and Ginger that might 'thin your blood'. It is absurd to the point of the ridiculous, but fear is a universal driver, and fear has also been long proven to be effective when used to manipulate and control others.

I realise that the reader who comes to a page like this is unlikely to be swayed by such misinformation, but I nevertheless want to remind you that the reason that herbs cannot be patented or owned by any individual or corporation is that they are the people's medicine. They belong to us all and it is my great hope that you will learn how to use them safely and wisely for yourself and the people you care for. Be safe but do not be afraid.

Personal experiences

As is always the case with herbal medicines, there are far more healing ingredients in Willow Bark than only its salicylates and using the whole herb conveys deeper, albeit slower acting, benefits to the body.

I have found Willow bark to be a superb, natural anti-inflammatory. Its action is deep, gentle and sure. However, it really is very difficult to take as a tea or tincture, it's not just the bitterness, Willow is full of tannins as well (a massive 13%) and drinking a cup of strong Willow tea is about as face-puckering an ordeal as you could imagine! Still, in the olden days, if you had a choice between hideous pain or drinking the tea I doubt it was difficult for anyone to make up their mind.

I think that Willow bark tea is not well suited to internal use unless a more gentle anti-inflammatory option is unavailable however where it can be of terrific help is as an external wash for wounds or infections, see the 'Willow Bark Wash' below to see how to do it.

My personal prescribing of Willow Bark internally is nearly always as a concentrated powder that I give to people combined with a Turmeric concentrate in capsule form. I will gladly use quite high doses of these two herbs in combination when needed and they have given great benefit to many people in easing pain and suffering.

Willow bark achieves its best effects when used patiently over a few days, here you can see a lasting benefit in the way it helps the body to move through a healing process. The proof of this is when the pain or inflammation resolves and does not come back when you stop using the herbs.

Willow bark combines perfectly with Turmeric. It may also be used with much benefit alongside such herbs as Black Cohosh, Celery Seed, Licorice root, Chamomile or Peppermint.

Constitutional note

Much of the information here about the traditional uses of Willow is consistent with the model of thinking whereby one may treat problem A with herb B. There is value in this approach in how it helps us pass on useful knowledge to one another but where it falls short is that people are not all cut from the same cloth! Willow might work brilliantly for one person but less well for another with the same sort of symptoms -- why is this?

Part of the reason is that people vary in their constitutions as to whether they are either hotter or cooler and, at the same time, either dryer or damper. This useful and rather fascinating subject is introduced further here

Another big part of using the right herb when it is most needed comes from understanding the need to treat what is going wrong for the person that had led up to their getting a health condition. In this light, Willow can particularly offer its benefits when a cleansing action is needed in the 'cycle of healing' - more about that here

Please understand that I cannot advise you, including on products or dosage, without seeing you in person in my clinic but for ideas on how you might find a good herbalist in your area read here

This living 'book' is my labour of love so, wherever you are, I wish you peace & good health!
