“Turmeric,” turˌmeˈric. A name given to the tuber-like root of a plant found in Asia. As prepared for commerce the roots are of the size of the little finger, and two or three inches long, of a yellowish color. They have an odor like ginger, and an aromatic taste. They form an orange-yellow powder, which is used in dyeing. Prussian blue is prepared from prussic acid, potassium, and a solution of sulphate of iron. Gypsum is a native sulphate of lime, that, when calcined, forms plaster of Paris.
