Formulas Name : Mercury and Leech Oil
Chinese Name : 汞蛭油
Drug Formulation
1 liang of mercury, 7 dried leeches (ground into powder).
Source
*Shengji Zonglu*, Volume 101.
Processing
Combine the two ingredients in a small container made from 3 liang of silver. Place the mercury and leeches inside, then seal it with a mud mixture made from earthworms and soil, about half a finger thick. Bury it deeply in horse manure; after 49 days, remove it—it will have turned into black oil.
Instructions for Use
Use a fish bladder as a finger sleeve; periodically dip a small amount onto the mustache, and the oil will naturally flow backward to the root of the mustache, turning it black.
