For cases where medication is ineffective.
Dig a basin-shaped pit in the ground, six to seven cun deep, just large enough to accommodate the feet. Heat charcoal until red-hot, then spray strong vinegar over it. Spread clean scallions (with skins and roots intact) evenly across the bottom.

To treat persistent rheumatic pain in the feet.

Zhongnan's Method

Four taels of fresh ginger, decocted into a strong bath solution, will cure the condition immediately.

Fengyan Cao (Phoenix Eye Herb), which refers to the clustered pods growing on the Toon tree (*Toona sinensis*). Burn these pods into charcoal, leach with water to extract the juice, and use it to wash the hair. After one year of use, the eyes will become clear like those of a child. Adding charcoal made from Toon bark is even better.

In the past, Song Zhongfu of Wusheng Army suffered from this condition for twenty years. Using this method for two years restored his vision completely.
Fresh green mulberry leaves are finely ground and dried by baking. They are processed monthly according to the days, burned in situ to retain their medicinal properties (Cun Xing). Take one he (a traditional unit of volume) per dose, decoct in a porcelain vessel until reduced by two parts, pour out the clear liquid, and wash with the warm solution.

Wash the affected area with dozens of snails; it will be cured after two treatments. Three bowls of water are sufficient to decoct thirty snails.

When swelling occurs, use equal parts of *Pueraria lobata* root (Zi Ge), *Polygonum aviculare* (Tian Qiao Mai), *Lonicera japonica* stem (Ren Dong Teng), and *Carex* species (Jin Si Cao), decoct in water, and wash. When ulceration occurs, use Angelica dahurica (Bai Zhi), Licorice root (Gan Cao), Notopterygium root (Qiang Huo), and Scutellaria root (Huang Qin), and expose/wash [text implies application or washing].

Equal parts of Phellodendron bark (Huang Bo) and Mirabilite (Pi Xiao) are ground into fine powder. For already ulcerated lesions, use seven parts Huang Bo and three parts Pi Xiao; for non-ulcerated red and swollen lesions, use half and half; for early-stage lesions, use seven parts Pi Xiao and three parts Huang Bo.

Four liang of Mugwort wool (Ai Rong), shaped to match the size of the lesion, mixed with four liang of Sichuan Peppercorn (Chuan Jiao).
