Common Asarabacca. Nat. Ord. AristolochiAe. Linn. Syst. Dodecandria Monogynia. Hab. England.
Med. Prop. and Action. The dried leaves and the dried root were formerly much used as emetics, but they are so violent in their operation that they are deservedly discarded. They are also cathartic and diuretic. The powder of the leaves is occasionally used as an errhine. It excites a copious discharge of mucus from the nose, which has been observed to continue for two or three days. Its action is that of a counter-irritant. Active principle, Asarine.
As an errhine (the leaves should be very finely powdered and well snuffed up the nostrils), Asarabacca has been employed in - 1, Severe Headaches; 2, Chronic Ophthalmia; 3, Chronic Affections of the Brain; 4, Paralysis of the Mouth and Tongue; 5, Toothache. (See Errhines, part ii.)
