(med) Bezoar. Synonym : gi wang. glang chen ghi wang / ba glang gi ghi wang / phag ghi wang, Concretion in elephant's entrails, Bezoar from cattle, concretion from pig (Phrin Las 1987). ghi wang (Bezoar) and rdo mkhris (gallstones) are depicted in the thangka images (Phrin Las 1987) as rather amorphous masses, whereas dbang ril (enteroliths, 'treating stones') are depicted as round stones. In modern publications ghi wang seems to be considered as gallstone.
A bezoar is a compact mass or concretion of indigestable organic or inorganic material found in the gastrointestinal system. The concretions may develop into enteroliths. The term has both a modern (pathological, scientific) and traditional usage. Food boluses (or boli) have the archaic and positive meaning of bezoar. The word is derived from the Persian pād-zahr, "antidote", and remained popular in Europe until the 18th century. It was believed that a drinking glass which contained a bezoar could neutralize any poison. Modern examinations show that when bezoars are immersed in an arsenic-laced solution, they can remove the poison. The toxic compounds in arsenic are arsenate and arsenite; each is acted upon differently by the bezoars: arsenate is removed by being exchanged for phosphate in brushite found in the stones, while arsenite is bound to sulfur compounds in the protein of degraded hair, which is a key component in bezoars (wikipedia).
