BACK TO HERBAL WIKI INDEX
Zanthoxylum americanum at the Real Jardín Botánico de Madrid  

Prickly Ash is a small tree, large shrub; with large spine-tipped corky lumps in her bark.  Americanum is native to the North Eastern US while Z. clava-herculis is native to Southern U.S.  It is found in old fields that are abandoned and returning to forest.  The sharp thorns keep out intruders and allow nature to reassert her dominion.  So a signature of doctrines-that is a powerful remedy for torturous pain.  
 
(This herb really tastes prickly, it is almost impossible to get cats to eat it voluntary. The herb can be taken homeopathic specific for neurasthenic patients who are thin, emaciated; poor assimilation with insomnia and occipital headache. Actually reading the proving of Xanthoxylum, it sounds like Lyme disease; lots of neuralgic shooting pains, pricking and throbbing sensation with flashes of pain in the hand; sciatica, anterior crural pain. Hmm....)

5. Promotes urination and resolves toxicosis
 
Samuel Thomson used Prickly Ash as one of his "diffusives"- a remedy that causing a diffusing sensation through the nerves and act as stimulating catalysts in a formula.  The Native Americans used the bark of the root as a specific for gonorrhoea.  (only in the BHP, did I find lots of indications of urinary track stuff)  From this came the popular use as a remedy for debility of the mucosa.  It improves capillary circulation, bringing the blood to the skin and mucosa.

Specific indications: Prickly ash impresses the secretions and the nervous and circulatory systems. The bark, when chewed, imparts a sweetish aromatic taste, followed by bitterness and persistent acridity;  The drug has remarkable sialagogue properties.  Swallowed it warms the stomach and augments the secretion of the gastric and intestinal juices, and probably increases hepatic and pancreatic activity.  The action of the heart is strengthened, the pulse slightly quickened, and the glands of the skin are stimulated to greater activity.

Therapy-"Is particularly grateful in stomach disorders.  It is an ideal gastric stimulant, and as a remedy for simple gastric atony it ranks well with capsicum. It is also of value in constipation when due to deficient secretion.  It was greatly valued in spasmodic conditions of the bowels with colic, and in choler amorbus in weak individuals, and to restore tone and normal secretion after attacks of epidemic dysentery.

As a stimulant to sluggish membranes, prickly ash may be given internally in dry, glazed pharyngitis with crusts of adherent, dried mucus.  Of its alterative power there is no question, and prickly ash is an ingredient in "Trifolium compound" (Barbara, do you know what else is in this? I think it might be one part Leptandrin and four parts of Prickly Ash bark but I am not sure) which has been used in extensively in chronic syphilitic dyscrasia. (it renders syphilitics more amenable to reparation of tissues.  A tincture of prickly ash berries is the best drug that can be given in so-called chronic muscular rheumatism; and it is not without value in lumbago and myalgia.  Chewing Prickly ash bark is a domestic custom for the relief of toothache.

It should also be remembered when nerve force is low and in the recuperative stage from attacks of neuritis or other forms of nerve involvement in which function is greatly impaired but is yet capable of restoration.

The circulation, skin, salivary glands ,and lymphatic system feel most of its influence; the serous and mucous tissues, and the kidneys, also being acted on.  It is suited only to languid conditions, an should mot be employed when the stomach is irritable.  A warm infusion favors full outward circulation and is of service in all cases of capillary stagnation with blunted sensibilities, as recent colds from exposure, colic from exposure.  In sub-acute and chronic rheumatism, it is an agent of the most excellent qualities.
 
MATTHEW WOOD - talks about Prickly Ash treating a depressed tissue state:
Specific Indication:
Writhing in agony; torment of the most intense kind; nerve damage; numb, tingling, painful: Hemiplegia ( Bell's palsy), nerve debility, withered, weakness.; Head sores; weak digestion; edema; Cold extremities and joints, arthritis, rheumatism.
 
BHP: acute or chronic urinary inflammation, prostatis, enuresis; small urinary stones due to phosphate or uric acrid.
 
Prickly Ash Berry is like the related Sichuan peppercorn; Chuan Jiao.
