[Prescription Verse] Bai Bo Feng (a disease characterized by white patches on the skin) arises on the face and neck; wind pathogen contends with healthy qi, forming white spots. In severe cases, it spreads over the whole body without pain or itching. Treatment should employ dispelling wind and applying ointments for recovery.
[Annotation] This condition starts from the face and extends to the neck; the skin color suddenly turns white, resembling spots, without itching or pain. It is caused by wind pathogen contending within the skin, leading to disharmony of Qi and Blood. Treatment should be initiated early; if delayed for a long time, it may spread to the entire body in severe cases. Initially administer Fuping Wan (Duckweed Pill), followed by Cang'er Gao (Xanthium Ointment). Externally, scrape the affected area first with pieces of pangolin scales until dryness and pain are felt, then apply eel fat three times daily. Another method involves washing the affected area with warm water collected from tree holes; after washing, grind equal parts of Cinnamomi Cortex (Guixin) and Ostreae Concha (Muli) into fine powder, mix with flour oil, and apply. Apply three times during the day and once at night; both methods are effective.

When using, scoop one spoonful with a mulberry wood spoon, hold in the mouth, and swallow with yellow wine. After taking the medicine, if there are areas where wind toxin exits, small sores the size of bean grains will appear; this indicates the expulsion of wind toxin. Pierce them to drain all fluid, and they will heal. Avoid pork.
