We studied biblographically on the origin of Zitanxiang which is commonly used at Oriental Traditional and Herbal Drugs Clinic. Results are as follows. We can find out that ; 1. In China, Pterocarpus indicus Wild. and Pterocapus santalinus L. which are duramen of woody parts of the plants of Leguminosae are used as Zitanxiang medicinal stuff. 2. In Korea, Sabina chinensis(L) Antoin (= Juniperus chinensis L.) which is the woody parts of Chinese cypress which is evergreen arbor and one of the plants of Cupressaceae is used as Zitanxiang medicinal stuff. Therefor, it is thought that comparison research have to be studied on these different Zitanxiang medicinal stuffs on the basis of efficacy.
