Uses of mercury with mica

Matsyakshi, girikarnika, shikhishikha, jangharuha and kshirini (the commentary: machheci, white kinihi, shikhi, kalihari, janghavriksha and milky-sap trees) are said to bring about the nirmukha union of mica and mercury, and the commentary says that using mica and mercury with their juices is beneficial in many diseases. With arama-shitala and vrishchika (the commentary: bidhuva grass) mica is fed to the mercury as its food, and the commentary says it then digests the mercury well.
