(The British Herbal Pharmacopoeia.)The root gave isoquinoline alkaloids 2-3%; palmatine, jaterorrhizine and its dimer bis-jateorrhizine, columbamine; bitters (including chasmanthin and palmanin). Volatile oil contains thymol.The alkaloid jateorrhizine is sedative, hypotensive. Palmatine is a uterine stimulant.As calumba contains very little volatile oil and no tannins, it is free from as- tringency which is common with other bitter herbs.The root alkaloids exhibit narcotic properties and side effects similar to morphine. It is no longer used (in Western herbal) as a digestive aid, and is rarely used as an antidiarrhoeal agent. (Natural Medicines Comprehensive Database, 2007.)
