Arca shell (calcined)

Ingredient Profile

Chinese Name煅瓦楞子
PinyinDuan Wa Leng Zi

Modern Research Perspective

Calcined Arca Shell contains calcium carbonate and trace minerals. Experimental research has examined acid-buffering, mineral, bone, and tissue-related effects, but bioavailability depends on particle size, purity, and preparation.

Clinical evidence for a standardized single shell material is sparse. Contaminants, calcium exposure, renal and gastrointestinal safety, dose, and interactions require further evaluation.

Traditional Function

Calcined Arca Shell is traditionally salty and neutral. It is used to soften hardness, disperse nodules, resolve phlegm, and control acid regurgitation or bleeding in selected patterns. Calcination and shell identity are essential.
