Chinese Sumach, Ailanthus glandulosa. Not official. Is given brief notice in Homeopathic and Eclectic literature. It is an emeto-cathartic and anthelmintic exceedingly disagreeable to the taste and, in sufficient dosage, is depressing to the nervous system. It contains a volatile oil which, when inhaled, produces a peculiar nausea. In spasmodic asthma, petit mat, palpitation of the heart, and other spasmodic affections it relieves the symptoms in 2- to 10-drop doses of the fl., but is so disagreeable it is not apt to become popular as a remedy. From my trials of the drug, I am convinced of its activity; but patients objected to it on account of its very disagreeable characteristics.
