What is it?

In herbal medicine we use the roots of 'Poke'; an impressive looking plant reaching 4 meters in height and having strong purple-green stems that support flourishes of drooping flowers eventually giving way to large clusters of purple berries.

How has it been used?

Poke Root is regarded as one of the most important of the American indigenous plants and one of the most striking in appearance. M. Grieves writes headaches of many sources are benefited by it... the extract has been used in chronic rheumatism and it is also stated to be of undoubted value as an internal remedy in cancer of the breast. As with all herbal authors on Poke Root Grieve emphasises the need for caution describing its potential action in higher doses as a slow emetic and purgative with narcotic properties.

Poke Root is a powerful cleansing remedy, used to help especially when the lymphatic system has become congested. This may show up in the early stages as being chronically tired with slightly swollen glands but by the time the lymph has really sludged up things may have gone all the way down to advanced rheumatism, respiratory disease or auto-immunity issues; conditions that Poke Root has traditionally been used to treat.

The following is an excerpt from a detailed description of the actions and indications by one of the great Eclectic physicians of the late 19th century; H Felter
Actions: 'Physiologically, phytolacca acts upon the skin, the glandular structures, especially those of the mouth, throat, sexual system, and very markedly upon the mammary glands; also upon the fibrous and serous tissues, and mucous membranes of the digestive and urinary tracts. It is principally eliminated by the kidneys. Applied to the skin, either in the form of juice, strong decoction, or poultice of the root, it produces an erythematous, sometimes pustular, eruption. The powdered root when inhaled is very irritating to the respiratory passages, and often produces a severe coryza, with headache and prostration, pain in chest, back, and abdomen, conjunctival injection and ocular irritation, and occasionally causes violent emeto-catharsis. Upon the gastro-intestinal tract doses of from 10 to 30 grains of it act as an emetic and drastic cathartic, producing nausea which comes on slowly, amounting almost to anguish, finally after an hour or so resulting in emesis. It then continues to act upon the bowels, the purging being prolonged for a considerable length of time. Large doses produce powerful emeto-catharsis, with loss of muscular power -occasionally spasmodic action takes place, and frequently a tingling or prickling sensation over the whole surface. Dimness of vision, diplopia, vertigo, and drowsiness are occasioned by large doses not sufficient to produce death. Phytolacca slows the heart’s action, reduces the force of the pulse, and lessens the respiratory movements. It is a paralyzer of the spinal cord, acting In poisoning by this agent tetanic convulsions may ensue. The treatment of poisoning by phytolacca is that of gastro-enteritis'
Internal Use: 'Medicines which act directly upon the glandular structures are not numerous. Among those that do so act, none is more direct than phytolacca. The experience of many years with phytolacca with success in what has been understood to be alterative effects, is a matter of Eclectic record. That it powerfully impresses the glands of the skin, lymphatic system, buccal, nasal, and sexual systems, and particularly the tonsils, ovaries, testicles, and mammary glands, we are certain.
Phytolacca is pre-eminently a remedy for swollen or engorged glands and adenitis. Without phytolacca we should be at a loss to know how to treat glandular affections undergoing swelling or inflammation. Its most direct indication is hard, painful enlargement of the glands with associated pallid mucous membranes. It is not so direct a remedy for suppurating glands. It is of signal value in mumps, and inflammation of cervical, axillary, and inguinal glands, when not due to tuberculosis. Even then its influence is often shown by its power to reduce the glands more or less, but exceedingly slowly; while in those enlargements due to syphilis its effects are more prompt and decided. Its beneficial control over tonsillitis and swelling of the submaxillary glands is well known. In acute mastitis phytolacca is by far our best remedy. This treatment, with mechanical support, gentle withdrawal of the milk, if possible, or sometimes strapping of the gland with adhesive plaster may avert suppuration. After surgical measures for the liberation of pus the use of phytolacca should be continued to reduce any remaining engorgement of the organ. Sore nipples and mammary tenderness, and morbid sensitiveness of the breasts during menstruation are relieved by phytolacca, and it is decidedly useful in the mammary swelling which sometimes occurs in infants. Though its action upon the reproductive glands is less decided than upon other specialized glands and upon the lymphatic nodes, it is not without value sometimes in orchitis and ovaritis. It is most effectual in the former when the inflammation is occasioned by the metastasis of mumps.
Phytolacca is important in dermatological practice.The condition which calls for it internally in skin diseases is one of indolent action of the skin, usually associated with vitiated blood and hard glandular enlargements. There may be scaly, vesicular, pustular, or tuberculous eruptions, and lymphatic enlargements with pain. The skin may be inflamed, but does not itch because there is not activity enough in the part. It is often indicated in chronic eczema, syphilitic eruptions, psoriasis, tinea capitis, favus, and varicose and other ulcers of the leg'

From earlier in the 20th century another great Eclectic physician, Finlay Ellingwood, writes the following on Poke Root 'this agent must now have especial attention in its influence in the treatment of acute inflammations of the throat. It makes but little difference what forms of throat disease we have, from the simplest forms of pharyngitis, through all the variations of tonsillitis, to the extreme forms of diphtheria, this remedy may be given in conjunction with other indicated agents. But few of our physicians neglect its administration in these cases, and they are unitedly profuse in their praises of its influence. If there be an infection of the local glands of the neck, from the throat disease, the agent should be applied externally, as well as administered internally. In the treatment of goitre there is a consensus of opinion concerning the value of this remedy, but it is almost universally administered in these cases, with other more direct remedies. Dr. J. V. Stevens is enthusiastic in his opinion that adenitis needs no other remedy than phytolacca americana. Whatever the cause of the disease or of however long standing, he saturates the system with this remedy, and persists in it, applies it externally and claims to cure his cases. He has used it for many years with success. Others combine other active alteratives as general conditions demand.
Too much cannot be said of its very positive and invariable influence in the treatment of acute inflammations of the breast during or preceding lactation. It should be given every two hours at least in doses of perhaps ten drops in extreme cases, or five drops in the incipiency of the disease, or mild cases.
The writer has, through a long experience, gotten into the habit of adding this remedy to alterative compounds. This is especially true of those prescribed for children's glandular and skin disorders. It is an efficacious remedy in any of the forms of skin disease, common to childhood. Given in the incipiency of eczema and in some forms of chronic eczema, especially that of a dry character, where there are cracks or fissures in the skin, these promptly yield to the internal administration of this remedy'

King's Dispensatory writes 'Physiologically, Poke Root acts upon the skin, the glandular structures, especially those of the buccal cavity, throat, sexual system, and very markedly upon the mammary glands. It further acts upon the fibrous and serous tissues, and mucous membranes of the digestive and urinary tracts. In certain conditions of the system which might come under the head of dyscrasia (bad blood), it proves a most valuable alterative. Scrofulous, syphilitic, and rheumatic conditions are invariably benefited by it. It is best suited to chronic rheumatism, and syphilitic and rheumatic joint affections. The condition which calls for it is one of indolent action of the skin; it is often indicated in chronic eczema, syphilitic eruptions, psoriasis, tinea capitis, favus, and varicose and other ulcers of the leg. In diseases of the mouth and throat it is highly esteemed. It is useful in acute and chronic mucous affections, as in tracheitis, laryngitis, influenza, catarrh, and especially in those affections where there is a tendency to the formation of catarrh and phlegm'

The British Herbal Pharmacopoeia (BHP) describes Poke Root's actions as antirheumatic, anticatarrhal, mild anodyne, emetic & purgative in large doses, and says it is indicated for chronic rheumatism, chronic respiratory catarrh, tonsillitis, laryngitis, adenitis, mastitis & mumps and specifically indicated for inflammatory conditions of the upper respiratory tract, lymphatic adenitis. The BHP suggests a dose of 0.03 - 0.3 gms or by decoction and suggests a tincture in the ratio of 1:10 in 45% ethanol with a dose of 0.2-0.6mls (approx 4-12 drops)

Thomas Bartram describes Poke Root's actions as 'lymphatic, alterative, anti-neoplastic, parasiticide, anti-rheumatic & anti-inflammatory'. He gives many potential uses for it, including 'swollen glands and lymph nodes, mumps, tonsillitis, sore throat, inflammation of prostate gland, ovaries or testicles. Chronic irritative skin disorders, ringworm, eczema, psoriasis, pityriasis, acne & lupus. Ulceration, internal or external, polymyalgia, rheumatism, arthritis. Breasts; mastitis, mammary abscess, fissured nipples, fibrotic nodules and hard lumps that have been diagnosed benign. Chronic fatigue syndrome. Obesity; eliminating excess fat in fatty degeneration. Mercurial poisoning from dental amalgam in teeth fillings. Lipoma with persistent use. Some forms of cancer spread via the lymphatic system for which Poke Root has an inhibitory effect'. Bartram suggests a dose of not more than 8mls in a week.

Science on Poke Root

~ Unsurprisingly, given its potential for toxicity, there are no clinical studies on people using Poke Root but there has been a little laboratory research that has shown that the saponins in Poke Root have anti-inflammatory activity (Woo WS, Shin KH, Kang SS, Soul Tachakkyo Saengyak Yonguso Opjukipip 1976;15:103-106)

~ It has also been conjectured that the immune system effects of Poke Root may be caused by the presence of substances called mitogenic lectins in the plant which may interact with gut associated lymphoid tissue and may be absorbed in small quantities. These lectins are used pharmacologically to stimulate cell division and increase the production of antibodies within white blood cells (Basham TY, Toyoshima S, Finkelman F et al. Cell Immunol 1981;63(1):118-133)

Safety of Poke Root

Poke root should not be used medicinally by the young and nor should it be taken whilst pregnant or during breast-feeding. Excess doses of Poke Root may harm the liver and the kidneys and do lasting and severe damage to the nervous system. This is a herb that should only be prescribed by a qualified herbalist who is experienced in its safe use.

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

The first rule of medicine is; primum non nocere, ‘firstly do no harm’. I have great respect for Poke Root and have used it thousands of times in my work with people who need deep cleansing support; however this is a herb that must be used with great care. By the time you are taking enough Poke Root for it to do its healing and cleansing thing, there is a narrow threshold before it starts acting as a poison.

Too much Poke Root can definitely do considerable harm, but the much more common mistake made with Poke Root is to use it before the body is ready for the kind of cleansing it can produce. Unless it is used in very small dosages where its action will be rather diluted it is best to make sure the bowel and kidneys are working well before using Poke Root at any kind of strong medicinal dose.

Delving into its historical use, or simply reading the list of potential uses in, for example, the snippet from Bartram in the 'how it has been used' section above, one could easily say 'how could this remedy possibly be good for so many different kinds of problems?' It is not that the herb can cure all these conditions, rather that by virtue of it so powerfully influencing the cleansing process, it helps the body to heal itself.

In my own practice I will often give a drop or two and listen carefully to my patients pulse to gauge whether it strengthens or balances the pulse and also to get a sense of the degree of sensitivity - this ancient process is talked about in more depth here When I then use Poke root I typically measure the dose in drops per days and depending on the person I might use as little as 2 or 3 drops in a dose or as much as 12-15 drops in rare cases of acute need. This is from a fairly potent 1:5 tincture made in 40% ethanol. The average amount that I use in a treatment formula equates to about 4 drops per dose. You can see this dose practically demonstrated in the sample formula given in the page on detoxification found here

I always combine it with other herbs in formula. Likewise, the length of treatment could be as little as a week or it could be much more. Each time you use it you have to be thinking about how it will best work for that one individual. It is a herb to use with great care and respect and a willingness to appreciate how it may best exert its ability to influence that singular person's healing process...

Poke Root combines powerfully with Calendula and Cleavers to achieve deep and lasting cleansing for chronic stuck conditions. It also can work exceptionally well with Devil's Claw for arthritis and with Red Clover for stubborn skin problems.

Constitutional note

Much of the information here about the traditional uses of Poke Root is consistent with the model of thinking whereby one may treat problem A with plant B. There is value in this approach, especially in how it helps us pass on useful knowledge to one another, but it falls short in one vital area; and that is that people are not all cut from the same cloth! Something that works brilliantly for one person may do less for another -- 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, Poke Root can particularly offer its benefits when a cleansing action is needed in the 'cycle of healing', more about this 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!
