Zedoary, dried rhizomes, contains a number of terpenoids, including curcumene, curcumenone, curdione, curcumenol. Curzerenone, furanogermenone, germacrone, germacrone epoxide; a volatile oil (1.0—1.5%) resembling ginger oil, and starch (50%).
Zedoary is thought to stimulate bile production (due to sesquiterpene ketones) and gall bladder emptying (due to cucuminoid constituents).
The sesquiterpenes, germacrone, germacrone epoxide, curzerenone and curcumenol showed CNS depressant properties. Curzerenone also showed a potent protective effect against induced lesions in rats. Both curzerenone and curcumenol showed a moderate analgesic action.
The terpenoid furanogermenone exhibits antiallergic activity. (Powdered zedoary, mixed with fructose, is used as an antiallergant in Japan.)
