    Mentioned in the Shen Nong Ben Cao Jing as part of the superior class of minerals which can, with protracted taking, make the body light and prevent senility. This may suggest it was part of supplementing the diet when engaging in an "avoiding grain" (Bigu 辟穀) fasting regime to cultivate life (Yangsheng 養生). However, prolonged taking could result in copper toxicity (see below).

Suggested Daily Dosage: 0.3 - 1 g ground into powder and taken internally as pills, or applied externally to the eyes.


Cautions: Some sources list this substance as toxic although it is not mentioned in the Shen Nong Ben Cao Jing and considered non-toxic in the Ben Cao Gang Mu. Its toxic consideration probably comes from the potential of copper poisoning from over-consumption.
