Wenzhong's Melon Decoction (Wenzhong Gua Yin), a formula for treating Hongxiangjiao (Foot Qi disease) with vomiting, regurgitation, and inability to eat.
Fresh Melon (one melon, cut into four pieces, boiled in nine sheng of water until five sheng remain, strained) Baizhu (Atractylodis Rhizoma, four liang) Gancao (Glycyrrhizae Radix et Rhizoma, one liang, honey-fried) Shengjiang (Zingiberis Rhizoma Recens, two liang)
The above four herbs: chop the three herbs other than the fresh melon, add them to the juice of the fresh melon, boil until two sheng remain, strain, and take warm, divided into three doses. Avoid eating plums, peaches, sparrow meat, seaweed, and Songcai (Chinese cabbage). (Note: "Fresh melon" likely refers to Mugua [Chaenomeles Fruit], see Volume 9.)
Yannian's Poria Decoction (Yannian Fuling Yin), a formula primarily for Hongxiangjiao (Foot Qi disease) presenting with swelling, shortness of breath, rebellious qi ascending, stuffy heat and irritability in the heart and chest, vomiting, regurgitation, and inability to eat.
Fuling (Poria, three liang) Zisuye (Perillae Folium, three liang) Xingren (Prunus Semen, three liang) Jupi (Citri Reticulatae Pericarpium, three liang) Shengma (Cimicifugae Rhizoma, three liang) Chaihu (Bupleuri Radix, three liang) Shengjiang (Zingiberis Rhizoma Recens, four liang) Xijiao (Rhinocerotis Cornu, two liang, shaved) Binglang (Arecae Semen, twelve pieces, crushed including peel and seed)
The above nine herbs are chopped. Boil in eight sheng of water until two sheng and five he remain, strain, and take warm, divided into three doses. The interval between doses should be equivalent to the time it takes a person to walk eight li. Avoid vinegar-preserved foods. (From Volume 19.)
According to the *Bingyuan* (Source of Diseases), this condition arises from wind-damp toxic qi battling with blood and qi. When righteous qi clashes with pathogenic qi, but the righteous qi cannot disperse freely, pain results. When pathogens reside in the skin and cou-li (pores and interstices), blood and qi flow sluggishly, causing the skin to thicken. Scratching feels like touching fabric through clothing, with no sensation perceived; this is termed "Bu Ren" (loss of sensation/anesthesia). (From Volume 13.)
Su Gong's treatment for early-stage Hongxiangjiao characterized by loose skin on the feet and legs, numbness and loss of sensation in the feet, pain below the knees, twitching of the eyebrows and eyes, qi sensation under the left hypochondrium, exacerbation after full meals, heat above the diaphragm, cold below the umbilicus, deficiency of the heart with sweating in the yin regions accompanied by pain. This includes a supplementary decoction powder formula.
Huangqi (Astragali Radix) Renshen (Ginseng Radix) Duhuo (Angelicae Pubescentis Radix) Xiong (Ligustici Chuanxiong Rhizoma) Fangfeng (Saposhnikoviae Radix) Danggui (Angelicae Sinensis Radix) Guixin (Cinnamomi Ramulus) Bixie (Dioscoreae Hypoglaucae Rhizoma) Fangji (Stephaniae Tetrandrae Radix) (each six liang) Fuling (Poria) Baizhu (Atractylodis Rhizoma) Danshen (Salviae Miltiorrhizae Radix) (each eight liang) Fuzi (Aconiti Lateralis Radix Preparata, raw use) Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried) (each four liang) Xingren (Prunus Semen, peeled and core removed) Shengdihuang (Rehmanniae Radix Recens) Shengjiang (Zingiberis Rhizoma Recens) Cishi (Magnetitum) (twenty fen, crushed to the size of small beans)
The above eighteen herbs are all chopped. Divide into thirty doses. For each dose, use Shengjiang (two liang), Shengdihuang (one liang), and Xingren (fourteen pieces, crushed). Boil in two sheng of water until seven he remain, strain through cloth, and take at once. Take usually in the evening or at night; this will not interfere with official duties. If vomiting occurs, add Banxia (Pinelliae Rhizoma, one liang) and follow the previous method.
Additionally, there is Cezizi Wine, primarily for Hongxiangjiao (Foot Qi disease). It is indicated when symptoms flare in spring and summer, subsiding in autumn with reduced swelling and stabilized qi, but leaving weakness in the legs, inability to flex and extend, numbness in the feet, distension and stuffiness in the fingers preventing movement, and paralysis of the limbs, waist, neck, and back.
Cezizi (Aconiti Lateralis Radix Preparata, raw use) Ganjiang (Zingiberis Rhizoma, five liang each; fresh is better) Danshen (Salviae Miltiorrhizae Radix) Niuxi (Achyranthis Bidentatae Radix) (six liang each) Jinya (Chalcanthitum, crushed and wrapped in silk) Cishi (Magnetitum, as above) Dihuang (Rehmanniae Radix, ten liang each; use eight liang if dried) Fangfeng (Saposhnikoviae Radix) Guixin (Cinnamomi Ramulus) Tianxiong (Aconiti Kusnezoffii Radix, raw use) Renshen (Ginseng Radix) Xiong (Ligustici Chuanxiong Rhizoma) Danggui (Angelicae Sinensis Radix) Baizhu (Atractylodis Rhizoma) Xixin (Asari Radix et Rhizoma) (two liang each)
The above twenty-five herbs are chopped. Store in a silk bag, soak in six or seven dou of clear wine for seven days. One serving is one small cup, taken two to three times daily, adjusting the amount slightly according to individual tolerance.
