“ TURMERIC, the tuberous root of Curcuma longa, L., an herbaceous perennial plant belonging to the natural order Zingiberaceæ. It is a native of southern Asia, being cultivated on a large scale both on the mainland and in the islands of the Indian Ocean. Turmeric has been used from a remote period both as a condiment and as a dye stuff, and to a more limited extent as a medicine. In Europe it is employed chiefly as a dye, also as an ingredient in curry powder and as a chemical test for alkalies. ”
