Description
Wa Leng Zi (瓦楞子), botanically known as Concha Arcae — the shell of the blood clam (Scapharca subcrenata) or closely related Arcidae species — is a traditional mineral-shell decoction piece used in Traditional Chinese Medicine (TCM). Also written as 煅瓦楞子 (calcined Wa Leng Zi) when it has been heated to a friable state, this shell has long been prized as a softening, transforming, and stomach-harmonizing substance used to ease distension, support digestion, and address accumulations of phlegm and stagnant qi. Its nature is sweet, salty, and neutral, making it a gentle yet focused shell herb for regulating the middle burner and soothing the Stomach.
