Salty, astringent, slightly cold, non-toxic. Enters the Hand-Shaoyin Heart Meridian and Foot-Shaoyin Kidney Meridian.

It treats enuresis and seminal emission (slippage syndromes), eliminates goiter (thyroid enlargement) and scrofula/tubercles (lymph node tuberculosis or subcutaneous nodules). It descends Gallbladder Qi to eliminate epigastric fullness/stagnation, and astringes the Heart Spirit to calm palpitations and fright. It clears deficiency heat and vexation from consumptive diseases, and reduces the chills and fever of warm malaria. It treats prolapse due to metrorrhagia (heavy uterine bleeding), dysentery, and leukorrhea; and knots caused by hernia, zheng-jia masses (abdominal lumps), and accumulations.
