Formula固涩剂· 固表止汗

牡蛎散

Mǔ Lì Sǎn

Oyster Shell Powder

From Tai Ping Hui Min He Ji Ju Fang, this formula treats generalized vacuity with spontaneous sweating that worsens at night, palpitations, shortness of breath, and lassitude—from exterior insecurity with yin fluid leaking outward. The original formula contains mu li, huang qi, ma huang gen, and fu xiao mai. This data entry is structurally simplified; clinical use requires the complete original formula.
