Mu Li-Oesterschelp-Concha Ostreae

Mu Li (Oyster Shell) is a salty, astringent, and cool mineral substance in Traditional Chinese Medicine (TCM), traditionally used to anchor Yang, calm the spirit, soften hardness, and prevent leakage of fluids. It is particularly effective in cases of anxiety, insomnia, night sweats, palpitations, and hot flashes, especially when caused by Yin deficiency or Liver Yang rising. In calcined form (duan Mu Li), it has enhanced astringent effects and is widely used to stop leakage disorders.

Mu Li is also valued for its ability to soften hardness and disperse masses such as nodules or lumps due to phlegm or stasis.
