Bai Bo Feng (Vitiligo) is caused by wind-pathogens of the Lung channel flowing and accumulating between the skin, persisting for a long time without resolving. It mostly occurs on the neck and face, presenting as scattered white patches, but without sores or ulcers.

The above herbs are burned together on the night of a lunar eclipse, during the peak of the eclipse, ground finely into a powder. Each dose consists of one qian mixed with warm wine, taken three times daily. Additionally, apply vinegar topically to the affected area.
Formula for treating Bai Bo:
Liu Huang (Sulfur, 1 liang, finely ground), She Tui Pi (Snake Slough, one strip, calcined to ash), Cao Jue Ming (Cassiae Semen, 1 liang, raw use), Ban Xia (Pinellia Rhizome, 1 liang, raw use), Shu Pi (Tree Bark, 1 liang).
The above herbs are pounded and sieved into a fine powder, mixed with clear lacquer, and thinly applied to the white patches. Before applying the medicine, first cut a fresh Ba Dou (Croton Seed) in half and rub it on the white patch until the skin becomes slightly red.
