Treating dry and damp Hong Kong Foot in men and women. Zhao Sheng Zuoyuan Shancan transmitted this from a military officer in Xinzhou.
Xuan Hu Suo (Rhizoma Corydalis), Wei Ling Xian (Radix Clematidis) (remove nodes, each half liang), Po Gu Zhi (Fructus Psoraleae) (one liang, half raw, half stir-fried), Hei Qian Niu (Semen Phytolaccae) (one liang, half raw, half slow-roasted with water until fragrant, remove paper and do not use Ba Dou), Xuan Zhou Mu Gua (Fructus Chaenomelis) (one fruit, cut off the lid, fill with Ai Ye (Folium Artemisiae Argyi), replace the lid, tie tightly with hemp thread).

From Jing Qin's Prescription.
Quan Xie (Scorpio) (half liang), Tian Ma (Rhizoma Gastrodiae) (three qian), Cang Zhu (Rhizoma Atractylodis Chinensis) (remove coarse skin, one liang), Cao Wu Tou (Radix Aconiti Kusnezoffii) (remove skin and navel, two qian, used raw), Hei Fu Zi (Radix Aconiti Lateralis Preparata) (text missing here, inferred context only).
Grind into a fine powder and mix well. For Kidney Qi deficiency symptoms, mix one large qian with Dou Lin Jiu (Soybean Dripping Wine). Black soybeans can eliminate pain in the waist, feet, tendons, and bones; the effect is like magic. When the medicinal energy reaches the affected area, there will be slight numbness for a moment, and the disease will suddenly heal with the medicinal energy. If the pain is in the bone marrow, administer with Walnut Wine. This medicine treats both Shang Han (Cold Damage) and Zhong Feng (Wind Stroke) at their root. Chen Fengyuan, Prefect of Zhongzhou, recounted that while serving as Prefect of Fangzhou, he ate melons to cool down during summer heat. In autumn, he suddenly suffered pain in his right waist and leg, extending to the knee and shin, making flexion and extension difficult. His right foot was hard to move for a month. All medicines for waist and leg pain were ineffective. His son, Yun'an Penal Judge, seemed to obtain Yang Shen San (Kidney-Nourishing Powder) from Assistant Teacher Shang Xi.
The Alcohol Supervisor, nearly forty years old, with bodily deficiency, could not walk with both legs. He tried this medicine. After the first dose of two qian, his thighs became numb but he could stand. After the second dose of two qian, his big toe and little toe became numb, and he could gradually walk. After the third dose, he ran as before. Tai Shi Ju Shi obtained this prescription. During the Ji Chou year of the Gandao era, while in the prefectural staff office, Song Panyuan Shenyan suffered from chronic weakness in the feet and knees, unable to walk. He received the prescription. Days later, he expressed gratitude. Having suffered for years and taken every medicine without success, upon receiving this prescription, he prepared it immediately. Two doses showed results; five doses led to significant recovery, gaining strength to bow and rise. Days later, he added that after bathing, thin skin peeled off like paste, and his muscles and bones became clear and bright. The effect was like magic!
