Abstract
Extract of tea leaves or (-)-epigallocatechin gallate as the principal ingredient of the extract forms a complex with active aluminum hydroxide. The animal test using rats has established that these complexes have therapeutic effect for gastric ulcers, e.g. pylorus-ligated ulcer and indomethacin-induced ulcer, when orally administered. Tests were also undertaken for the effect on the secretion of gastric juice and acute toxicity of these complexes using rats and mice as the test animals.
