Tamarinds, cream of tartar, sal polychrestum, and stibiated nitre, agree best with hot climates, bilious constitutions, in the heat of summer, bilious diseases, attended with a violent heat, as in a continual double summer tertian, a burning fever, with intolerable thirst, because they restrain the intestine motion of the sulphureous parts of the blood and bile.
