The formula from *Tu Jing*: Most widely used for treating sores and rashes, it can also treat leprosy-like conditions. The method involves taking five jin of *Sophorae Radix* (Kushen), cutting them into pieces, and soaking them in three dou of fine wine for twenty days. Drink one he each time, without interruption daily. If numbness is felt, the condition will improve.

Another formula: Treats severe wind disease, promoting eyebrow regrowth. Use nine steamed and nine sun-dried leaves of *Platycladi Cacumen* (Cebaiye), sifted into powder, mixed with refined honey to form pills the size of paulownia seeds. Take thirty pills each time, washed down with warm boiled water. Take twice a day and once at night.

Yet another formula: Treats wind-leprosy causing pulling pain in the hypochondrium, vomiting upon onset, and tinnitus like cicada chirping. Use *Asparagi Radix* (Tianmendong) pounded into powder. Take three qian each time, mixed with wine, taken long after meals. Long-term use by humans can also prolong life.

Vitiligo refers to the skin on the face, neck, body, and limbs turning white, differing from normal flesh color, without itching or pain, hence called Vitiligo. This arises from wind pathogen clashing within the skin, leading to disharmony of Qi and Blood. Purple vitiligo often occurs on the limbs or body, presenting as purple nodules resembling red bean carbuncles. This results from the stagnation and accumulation of wind-heat. The treatment method for both red and white vitiligo uses the same formula.
