Latin NameEndothelium Corneum Gigeriae Galli

Modern Research Perspective

Experimental work on gizzard lining peptides and minerals suggests effects on gastric motility, digestive enzyme activity, and urinary crystallization in laboratory or animal models. Human clinical use has mainly been described in small observational or combined-herb studies for dyspepsia and urinary stone symptoms. Evidence is low certainty because preparations, doses, and co-treatments vary; controlled human trials and long-term safety data are scarce.

Traditional Function

In traditional Chinese medicine, gizzard lining is a thin, slightly sweet and astringent medicinal tissue used to support digestion, reduce food stagnation, and assist the movement of urinary stones.
