Hongxiangjiao (a disease characterized by swelling and weakness of the lower legs and feet) arises from constitutional deficiency and infection with wind-toxin pathogens. However, Hongxiangjiao is categorized into dry and damp types, as well as yin and yang syndromes. The dry type presents without swelling, whereas the damp type manifests with swelling and fullness.
The dry type of Hongxiangjiao results from kidney deficiency, lack of moderation in daily activities, exposure to wind while cooling off, sleeping with feet uncovered, standing or walking on wet ground, bathing with cold water during summer months, leading to reduced food intake, emaciation, qi stagnation in the heart and abdomen, constipation, upward rushing of wind-toxin causing mental restlessness and depression, and weakness in the four limbs. Its clinical manifestation is the absence of swelling in the feet and knees; hence it is named dry Hongxiangjiao.
To treat dry Hongxiangjiao where wind-toxin clamps onto the feet and knees, causing dryness within the skin, gradual thinning of the calves, pain in the bones, and occasional mental oppression, Sheng Gan Dihuang Wan (Raw Dried Rehmannia Pill) is indicated:
