Curcumae longae rhizoma, turmeric root.
Turmeric root consists of the finger-like, often tuber-like, scalded and dried rhizomes of Curcuma longa L. (syn. C. domestica Valeton and C. aromatica Salisbury) [Fam. Zingiberaceae], and their preparations in effective dosage.
The drug contains not less than 3 percent dicinnamoylmethane derivatives, calculated as curcumin, and not less than 3 percent volatile oil, both calculated on a dry-weight basis of the drug.
Unless otherwise prescribed:
Average daily dosage:
- 1.5 - 3 g of drug;
- equivalent preparations.
Comminuted drug, as well as other galenical preparations for internal use.
The choleretic action of curcumin is experimentally well documented. Further indications exist for a cholecystokinetic and a clear antiinflammatory action.
