Cathartic Diaphoretic Emetic Errhine Sternutatory Stimulant Tonic
Asarabacca has a long history of herbal use dating back at least to the time of the ancient Greeks, though it is little used in modern herbalism[268]. The root, leaves and stems are cathartic, diaphoretic, emetic, errhine, sternutatory, stimulant and tonic[4, 7, 9, 13, 21, 46, 240]. The plant has a strong peppery taste and smell[244]. It is used in the treatment of affections of the brain, eyes, throat and mouth[4, 19]. When taken as a snuff, it produces a copious flow of mucous[268]. The root is harvested in the spring and dried for later use[7]. Use with caution[21], see the notes above on toxicity. An essential oil in the root contains 50% asarone and is 65% more toxic than peppermint oil[240]. This essential oil is the emetic and expectorant principle of the plant and is of value in the treatment of digestive tract lesions, silicosis, dry pharyngeal and laryngeal catarrh etc[240].

Plant Propagation
Seed - best sown in a cold frame as soon as it is ripe in the summer[134]. Stored seed will require 3 weeks cold stratification and should be sown in late winter[134]. The seed usually germinates in the spring in 1 - 4 or more weeks at 18°c[134]. When large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in the greenhouse for at least their first winter. Plant them out when large enough in late spring. Division in spring or autumn. Plants are slow to increase[200]. It is best to pot the divisions up and keep them in light shade in the greenhouse until they are growing away strongly.
