The armpits, palms and soles of the hands and feet, inner thighs, and scrotum often have sweat that stains clothes, hence the name.
Main Formula: Gouqigen (Root of Lycii), Qiangweigen (Root of Rosae Rugosae), Gancao (Licorice Root) (each 1 liang); Shanglu (Radix Phytolaccae), Qianfen (Lead Carbonate), Huashi (Talcum) (each 5 qian). Grind the above herbs into a fine powder, mix with a small amount of vinegar, and apply frequently to all affected areas until healed.
Simple Prescription: Mutoutou (Ficus hirta growing on walls) decocted in water to wash the affected areas, followed by application of Mituosen (Litharge) ground into powder.
Zhangqi (Miasma) arises in Fujian, Guangdong, and the Lingnan region. Mountain mists cause dampness; minerals and stones generate water; there is much fog and little wind, leading to stagnation and steaming heat. Winters are not very cold, causing pores to open and sweat to flow; summer months feature continuous rain, where latent summerheat and cold invade. Cold and heat are uneven, and yin and yang contend. Travelers and scholars stranded away from home suffer from irregular diet and physical exhaustion due to rough journeys, damaging qi and causing deficiency. Those with mild exposure experience aversion to cold and shivering resembling malaria, called Lengzhang (Cold Miasma). Severe cases involve accumulated heat causing mental confusion and lethargy, as if lying in hot ashes, called Rezhang (Hot Miasma). The most severe cases result in immediate loss of voice upon illness onset, called Yazhang (Mute Miasma). Recurrence during the journey home is called Huitouzhang (Return Miasma); symptoms resemble Shanghan (Cold Damage), but profuse sweating, emesis, or purgation are contraindicated. Treatment can follow Shanghan methods. Jaundice should be treated according to Shanghan jaundice protocols. Folk wisdom states: "Do not drink wine at Mao hour (5-7 AM), do not eat rice at Shen hour (3-5 PM)." It is also said: "Miasma infects those who labor excessively and have weak constitutions; excessive drinking is harmful, but eating well prevents issues." After recovery, wash the face after seven days, comb hair after fourteen days, and for twenty-one days abstain from alcohol, pungent/fishy foods, and sexual activity. All treatment methods are detailed under Wanbing Yushu Dan (Universal Medicine Jade Pivot Pill, see Gu Du chapter). At the first sign of discomfort, take it dissolved in water; or chew and swallow frequently, combined with Suhe Xiang Wan (Styrax Pill, see Zhong Han chapter). If feeling cold, drink hot wine, ginger soup, or boiling water. For Lengzhang (Cold Miasma), use Zhengqi San; in summer months, use Liuhe Tang; for Rezhang (Hot Miasma) and Yazhang (Mute Miasma), use Caozi Fa (Grass Seed Method); for body heat and headache, use Hejie San. If initially exposed to cold transforming into fever, irritability, and thirst, yet unable to swallow water, Fuzi Tang (Aconite Decoction) is still appropriate, decocted raw and taken cold (resembling Yin syndrome presenting as Yang). For severe irritability, add Zhuru (Bambusae Caulis in Taeniam); for severe thirst, add Renshen (Ginseng Radix) and Wuweizi (Schisandrae Fructus); for hiccup, add Dingxiang (Caryophylli Flos) and Danzhuye (Lophatheri Herba); for severe irritability and thirst, use Zhuye Shigao Tang (Leaf and Gypsum Decoction) minus Shigao (Gypsum Fibrosum), plus Shufuzi (Prepared Aconiti Lateralis Radix), or take with cold water; for cold feet and deficient sweating on the head/forehead, use Jiangfu Tang (Ginger and Aconite Decoction) and moxa Qihai (CV6, 2 cun below umbilicus). Do not pre-administer Fuzi (Aconite) unless there is upper heat and lower cold. Upon initial exposure, use the Main Formula, then Hejie San. If Shanghan headache and fever occur, take Qianghuo Chonghe Tang. If chills and fever alternate, give Xiaochaihu Tang (Minor Bupleurum Decoction) temporarily. Only administer Fuzi (Aconite) and other hot medicines after confirming cold syndrome. To dissipate blood stasis, use Heishen San (Black Divine Pill, see Chan Hou chapter).
