Taken as a water-milled liquid, it is effective for injuries caused by snakes, insects, bees, scorpions, wild wolves, dog bites, and poisoned arrows; applied externally as a powder, it is also excellent. (Recorded by Famous Physicians) [Origin] (Bencao Yan Yi states) It originates from Mount Emei, resembling crystal in clarity and transparency. When illuminated by sunlight, it displays five colors like the halo of a Buddha, hence its name. It is rarely used by contemporary physicians. (Mingyi Bie Lu records) In Jiazhou, Mount Emei, there is Pusa Shi, which people often collect. Its color is bright white and lustrous, similar to the wild wolf tooth stone from Mount Tai or the rock crystal from Shangrao Prefecture. Sunlight shining upon it produces five-colored light, resembling the circular halo of a Buddha's head. [Harvest] (Growth) No fixed season. (Collection) No fixed season.

Posuo Shi (Mo Suo Stone / Malachite variant): Primarily resolves all drug toxicities, heat oppression, headache caused by miasma epidemics. (Recorded by Famous Physicians) [Name] Mo Suo Shi. [Origin] (Bencao Tujing states) Produced in the South Sea, Hu people value it highly. Those without spots and containing gold stars, when ground into a milky liquid, are of the highest grade. Decorated with gold to make finger rings, they are held in the mouth and sucked several times before and after meals to prevent poisoning. Currently, a piece the size of a fingernail commands a very high price. There is also Dou Ban Shi (Bean-spotted Stone); although it can resolve toxins, its efficacy is inferior. There is also Elv Shi, which has grain patterns and turns iron into copper color when ground; people often use this as a substitute, not the true product. To verify authenticity, grind with water and drop onto fresh chicken comb blood; if it dissolves into water, it is genuine. [Harvest] (Growth) No fixed season. (Collection) No fixed season.
