Astringes Jing and restrains vaginal discharge
Traditional Chinese Uses
Long Yan Hua is the dried flower of the longan tree (Dimocarpus longan, Sapindaceae; Flos Longanae), used as an astringent herb entering the Liver and Kidney channels. Its role is to astringe Essence (Jing) and restrain leakage of fluids: it is used for spermatorrhea and seminal loss and for excessive or persistent vaginal discharge (leukorrhea), and by extension for turbid, frequent urination associated with Kidney insufficiency. It is a relatively minor materia medica item, far less used than longan fruit flesh (Long Yan Rou).
The flower is typically prepared as an infusion or decoction. It is best suited to consolidating, deficiency-type leakage patterns and is usually combined with tonifying and stabilizing herbs; it should be used under professional guidance rather than as a stand-alone remedy.
