*Chiao* (those with purple backs and thick flesh, also known as *Chang'e*), 1 fen; raw *Gancao* (Licorice Root), 1 fen; *Qingfen* (Calomel), half a qian in weight.
Calcine the *Chiao* sealed with salt mud, obtain one liang of the powder, mix with *Gancao* powder, and grind uniformly with *Qingfen*. Take four qian bi (small spoonfuls) mixed with strong decoction of *Gualuo* wine. Administer at the fifth watch (early morning); continue until foul matter is discharged. If ineffective, prepare another dose. One *Gualuo* per dose, boiled in one bowl of wine until reduced to one bowl.

Slowly boil the ingredients in a silver or earthenware vessel until they form an ointment. Take two large spoons each time, mixed with warm wine, administered at any time.

When the surrounding swelling subsides, further concentrate the small sore heads, then apply the subsequent medicine.
