The Kidney governs the feet. If Kidney Qi is deficient, Wind-Dampness pathogens invade and attack the feet and knees, a condition known as Xianggangjiao (Hong Kong Foot / Podagra). Due to the stagnation of Qi and Blood and the prevalence of Damp-Toxicity within the skin, it is difficult to heal.

Crush and sieve the above ingredients into a powder. Take 4 qian per dose. Add 1 zhongzhan of water and 0.5 banfen of fresh ginger. Decoct until reduced to 6 fen. Strain. Take at any time.
For treating Hong Kong Foot with Wind-Toxicity causing sore swelling and pain, the Qinjiao Powder Formula (Qinjiao San Fang).

Crush and sieve the above ingredients into fine powder. Mix with refined honey and pound 200-300 times. Form pills the size of paulownia seeds. Take 30 pills at any time, washed down with warm wine.
