Botanical Description
Wen Ge is not a plant but the shell of the Asiatic hard clam, Meretrix meretrix (Linnaeus), a bivalve mollusc in the family Veneridae inhabiting sandy intertidal and shallow subtidal zones along the coasts of eastern and southeastern Asia. The shell is solid, equivalve, triangular-ovate to subtrigonal, typically 4-9 cm long, with a smooth, polished exterior bearing fine concentric growth lines and variable coloration ranging from cream and grey-brown to glossy purplish-brown with darker zig-zag patterns. The interior is porcelain white, often tinged purple at the posterior margin. For medicinal use the shells are collected, cleaned, sun-dried, and frequently calcined before being pulverised.

Cultural & Historical Context
Traditional Chinese Uses
Wen Ge (meretrix clam shell, clamshell) is a cold, salty mineral-rich substance used in Chinese medicine to clear Heat, transform stubborn Phlegm, and soften hard accumulations. It is commonly used for coughs with thick, sticky Phlegm, goiter and thyroid nodules from Phlegm accumulation, and excessive thirst and acid regurgitation from Stomach Heat. In its calcined form, it strongly neutralizes stomach acid for hyperacidity-related pain. Applied externally as a powder, it dries and soothes eczema, skin sores, and weeping lesions.
