OBJECTIVEHerein, the synthesis, component, microstructure and pharmacological and toxicology researches of the Synthetic Mercury Sulfide (S-HgS) a kind of common drug in Chinese, Mongolia, Tibetan medicine, and Indian medicine system were summarized. The similar cognition about mercury toxicity & pharmacological action from some Asian regions was analyzed, and it can supply some useful direction for the traditional Asian medicine system.

METHODRecent literatures both domestic and abroad were summarized and analyzed.

RESULTS-HgS is the basis of Vermilion, Mongolia-Vermilion, Zuotai, and Ras-sindoor. Athough the processes of synthesis are very different, but the microstructure and pharmacological & toxicology of S-HgS is similar.

CONCLUSIONS-HgS has a far-ranging application,and unique curative effect. New technology such as nanotechnology can be used for improving the advancement of traditional Asian medicine.
