copper, for the Bhávaprakása says it contains some copper and therefore possesses some of the properties of that metal.* It is described in this work as astringent, emetic, caustic, and useful in eye diseases, skin diseases, poisoning etc. It is purified for internal use, by being rubbed with honey and ghee and exposed to heat in a crucible. It is then soaked for three days in whey, and dried. Sulphate of copper thus prepared is said not to produce vomiting when taken internally. Dose, one to two grains.
