Oyster Shell Powder (Ostrea gigas) — Fine Food-Grade Mineral Powder, 500g Bulk

Oyster Shell Powder (Ostrea gigas) is the finely milled, sun-dried shell of the oyster, a mineral-rich food herb known in Traditional Chinese Medicine (TCM) as Mǔ Lì (牡蛎). Revered for centuries as a heavy, settling, and yang-anchoring substance, Mu Li has been prized for calming the spirit, subduing rising yang, and harmonizing the Liver. Its nature is salty, astringent, and slightly cold, making it a grounding yet gentle mineral ingredient for traditional food wellness and external preparations.

It is also used in traditional congee and medicinal food preparations, and in external poultices and foot soaks where its heavy, settling nature is applied topically. As a daily food herb, it is added in small amounts to broths and grain dishes for its mineral character.
