Botanical Description
Pi Shuang is the Chinese name for refined arsenic trioxide (As2O3), historically prepared by sublimation of arsenical ores such as arsenolite or realgar (Pi Shi). It appears as a white, crystalline, odorless powder, extremely toxic in even minute oral doses, with a recorded fatal dose under 100 mg. Classical Chinese materia medica employed Pi Shuang externally for malignant ulcers and obstinate skin lesions, and internally in trace amounts within compound formulas for chronic asthma and certain malignancies. Modern pharmacology has confirmed activity of arsenic trioxide against acute promyelocytic leukemia, where it is administered as a tightly controlled pharmaceutical (Trisenox). Unregulated internal use is universally discouraged due to severe systemic toxicity, carcinogenicity, and risk of fatal poisoning.
