The dried Forsythia fruit has been used since ancient times as an antidote, an anti-inflammatory agent and a diuretic in Japan, Korea and China [9]. In Japan, the dried fruit originating from F. suspensa Vahl or F viridissima Lindley (Oleaceae) is listed in the Japanese Pharmacopeia XIV as crude drugs Forsythiae Fructus . The dried fruit from F koreana Nakai is also used as crude drugs in Korea. On the other hand, the Forsythia leaves are used as health tea for cold in China.
