Dittany is an old English word which in England often means Dictamnus albus, a plant of the rue family. The name is supposed to be derived from Mt. Dicte, in Crete, where the ancient dittany grew. The Cretan dittany is supposed to be Origanum Dictamnus, a plant of the mint family, and of the same genus with the wild marjoram. The plant commonly called dittany in the eastern United States is Cunila origanoides, Brit. (C. Mariana, Linn.), another mint, native in dry lands. See Cunila. It has been used as a substitute for tea, and is a gentle aromatic stimulant. All these plants yield an oil used as a mild tonic.
