The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states: "When the pulse is affected by wind, leprosy (Lifeng, a severe skin disease characterized by numbness and deformity) forms." It also says: "Wind pathogen enters together with the Taiyang (Greater Yang) channel, travels through the Shu (Transport) points of various meridians, and scatters between the muscle layers. When Wei Qi (Defensive Qi) clashes with the pathogen, its pathway becomes obstructed. Consequently, the flesh swells and sores develop. If Wei Qi coagulates and fails to circulate, the muscles become insensible (numb)."
Regarding leprosy, it is caused by heat accumulation in Ying (Nutritive) and Wei (Defensive) Qi, which fails to dissipate. This leads to the collapse of the nasal bridge, deterioration of facial complexion, and ulceration of the skin. When cold and wind pathogens lodge in the vessels and do not depart, the condition is named leprosy, or alternatively, "cold-heat disorder." In cases of "Great Wind" (a severe form), there is heaviness in the bone joints, and loss of eyebrows and hair at the temples. This is called Great Wind. Treatment involves needling the muscles until sweating occurs for one hundred days; then needling into the bone marrow until sweating occurs for another hundred days. After a total of two hundred days, when the eyebrows and temple hair regrow, needling should cease.
In the first month of the Wuyin year, Duan Kusshi suffered from Great Wind. His face and neck were extremely itchy, and his eyebrows had already fallen out. Pouring hot water over the area provided slight relief, which he did several times day and night. Using Bian stones (stone needles) for pricking also brought some relief. My late master said: "Pulse wind is leprosy. Heat accumulation in Ying and Wei Qi causes turbid Qi, leading to nasal collapse and skin deterioration. Great Wind is caused by cold and wind lodging in the vessels. Treatment should involve needling the swollen areas with a sharp needle, pressing to expel evil Qi until the swelling subsides. One should eat only regular meals and avoid other foods. The appropriate prescription is Bqi Xierong Tang (Tonifying Qi and Draining Ying Decoction). This formula breaks blood stasis, clears heat, raises Yang, and relieves itching. It drains Ying heat using acrid-warm dispersants and sweet-warm elevators to unblock the Yangming channel, drains Heart Fire, and tonifies Lung Qi. This is the correct therapeutic approach."
[Bqi Xierong Tang / Tonifying Qi and Draining Ying Decoction]
Shengma (Rhizoma Cimicifugae), Lianqiao (Fructus Forsythiae) [6 fen each]; Jiegeng (Radix Platycodonis) [5 fen]; Huangqin (Radix Scutellariae) [4 fen]; Shengdihuang (Radix Rehmanniae Preparata) [4 fen]; Sumu (Santalum Rubrum); Huanglian (Rhizoma Coptidis); Huangbai (Cortex Phellodendri); Quanxie (Scorpio) [3 fen each]; Renshen (Radix Ginseng); Baidoukou (Fructus Amomi Rotundus) [2 fen each]; Gancao (Radix Glycyrrhizae) [1.5 fen]; Dilong (Pheretima) [3 fen]; Taoren (Semen Persicae) [3 seeds]; Mengchong (Nephentes/Mosquito Larvae? Note: Traditional text implies insect larvae used for breaking stasis, often interpreted as specific local insects or earthworms in some contexts, but literally 'mosquito worm' - here kept as Mengchong) [3 seeds, legs and wings removed]; Hutonglei (Resina Tamaricis) [1 fen, powdered]; Shexiang (Moschus) [a small amount, powdered]; Danggui (Radix Angelicae Sinensis) [3 fen]; Shuizhi (Hirudo) [3 seeds, stir-fried until smoke ceases].
These nineteen ingredients are processed as follows: Except for Lianqiao which is separately cut, Hutonglei is powdered, and Baidoukou is ground into powder. Shexiang, Mengchong, and Shuizhi are also ground into powder. All other herbs are combined as one dose. Add two cups of water and one cup of wine. Simmer together with Lianqiao until one cup remains. Strain the dregs. Re-add the powders of Hutonglei and Baidoukou, along with Shexiang and others. Simmer again over fire until 0.7 cups remain. Take warm. Administer after breakfast and before lunch. Avoid alcohol, wheat products, raw/cold, and hard foods.
