| Remarks | Usage of Pipaye: At first, the underside hairs of the leaf are eliminated. It is roasted for antitussive and expectorant uses. In order to regulate the stomach and relieve vomiting, the raw leaves are used. In Edo Period, the formulation "Biwayoto", of which the main ingredient is dried leaves of Biwa [Eriobotrya japonica (Thunb.) Lindl.] without hairs, was used to beat the summer heat. It is consisted of Huoxiang, Muxiang, Wuzhuyu, Rougui, Pipaye, Gancao and Ezhu. Though it is said to be a Japanese formulation, it dates back to Chinese Ming Dynasty. | |||||
