Take 3 qian of Dangguiwei (Tail of Angelica Sinensis Root), 1.5 qian of Badou Rou (Kernel of Croton Seed), and 4 liang of Mahua (Sesame Oil).

Take one large dried Chanha (Toad), 15 grains of Hujiao (Black Pepper), and 7 seeds of Zaoguo (Soap Bean Pod). Place in a clay jar, cover the mouth with a tile, and roast over charcoal fire until smoke ceases but the medicinal nature remains (Cun Xing). Remove and grind into an extremely fine powder.
