1. Overview
Wǎ Léng Zǐ (瓦楞子) — cockle / clam shell (Arcae Concha) — is a traditional animal-derived substance of the Chinese Materia Medica, historically placed in the category of herbs that resolve phlegm. It is described here for information and reference only. I do not use or prescribe Wǎ Léng Zǐ or any other animal product; I prescribe plant and mineral herbs in their place, matched to each patient's TCM pattern.

5. Why it is not prescribed
Although Wǎ Léng Zǐ may be used by some practitioners, I do not prescribe any animal-derived substances; plant and mineral herbs are used instead. All Chinese herbs should be prescribed by a fully qualified herbalist registered with the Register of Chinese Herbal Medicine (RCHM), which prohibits the use of endangered species. Dr (TCM) Attilio D'Alberto is a member of the RCHM and the British Acupuncture Council and does not use animal products of any kind.
