---Constituents---An acrid, volatile oil, brown colouring matter, gum, starch, chloride of calcium, woody fibre and a yellowish colouring matter named curcumin; this is obtained by digesting tumeric in boiling alcohol, filtering and evaporating the solution to dryness, the residue being digested in ether, filtered and evaporated.

---Medicinal Action and Uses---Tumeric is a mild aromatic stimulant seldom used in medicine except as a colouring. It was once a cure for jaundice. Its chief use is in the manufacture of curry powders. It is also used as an adulterant of mustard and a substitute for it and forms one of the ingredients of many cattle condiments. Tincture of Turmeric is used as a colouring agent, but the odour is fugitive. It dyes a rich yellow. Turmeric paper is prepared by soaking unglazed white paper in the tincture and then drying. Used as a test for alkaloids and boric acid.
