Abortifacient Antidote Cathartic Diaphoretic Diuretic Emetic Expectorant Sialagogue
Stimulant
Seneca snake root was employed medicinally by several native North American Indian tribes, who used it to treat a variety of complaints[257]. It is still used in modern herbalism where it is valued mainly as an expectorant and stimulant to treat bronchial asthma, chronic bronchitis and whooping cough[254].The root contains triterpenoid saponins, these promote the clearing of phlegm from the bronchial tubes. The root is antidote, cathartic, diaphoretic, diuretic, emetic, expectorant, sialagogue, stimulant[4, 21, 46, 165, 222, 238]. It was used by the North American Indians in the treatment of snake bites[4, 46] and has been found of use in the treatment of various respiratory problems including pleurisy and pneumonia[4, 257]. The root is harvested when the plant dies down in autumn and is dried for later use[4]. Use with caution[4, 21], excess doses cause diarrhoea and vomiting[238]. See also the notes above on toxicity. A tea made from the bark has been drunk in order to bring about a miscarriage[213]. The dried root is used as a stimulating expectorant - it is said to owe its medicinal value to the presence of saponins and in large doses is poisonous[213]. The root is harvested in the autumn[213]. The root has been used to treat snakebites, it is chewed and applied to the bite[213]. The German Commission E Monographs, a therapeutic guide to herbal medicine, approve Polygala senega for cough/bronchitis (see [302] for critics of commission E).
