The *Classic of Difficult Issues* (Jing Yun) states: The presentation of Wei Wind (Stomach Wind) is characterized by excessive sweating in the neck and aversion to wind, difficulty swallowing food and drink, obstruction in the chest and diaphragm, frequent abdominal distension, bloating upon exposure to cold, and diarrhea after consuming cold food. On examination, the body appears emaciated while the abdomen is distended.
Wei Wind refers to swelling of the head and face, with a wiry, moderate, and floating pulse at the right Guan position. It is often caused by being exposed to cool air after eating. Yu Jiayan stated that there are five variations of Wei Wind. The first is called "Wind transforming into Cold-Heat," meaning wind enters the Stomach and inevitably affects the Liver Wood, as wind Qi connects with the Liver. When Liver Wood is excessive, it overacts on Spleen Earth, generating alternating chills and fever. Quack doctors often mistake this for an external contraction, for which Xiao Chai Hu Tang (Minor Bupleurum Decoction) is appropriate. The second is called "Dan transforming into Xiao Zhong" (Gluttony transforming into Middle Consumption), where Dan refers to heat. Heat accumulating in the Stomach leads to voracious appetite but easy hunger, which is the harm of Fire; Bai Hu Jia Ren Shen Tang (White Tiger Decoction plus Ginseng) is appropriate. The third is called "Jue transforming into Dian Ji" (Reversal transforming into Head Disease), where Jue means reversal, referring to Stomach Qi reversing upward to the head, causing diseases of the vertex, such as vertigo; Xiong Xin Tang (Ligusticum and Asarum Decoction) is appropriate. The fourth is called "Long-term Wind leading to Sun Xie" (Undigested Diarrhea), meaning wind fire in the Stomach is intense, causing immediate diarrhea after eating without retention. If wind enters the Blood level, bright red blood is passed; if complicated by damp-heat, stool resembling bean dregs is passed; Ren Shen Wei Feng Tang (Ginseng Stomach Wind Decoction) is used, adding Fang Feng (Saposhnikovia Root) if there is bleeding. The fifth is called "Pulse Wind leading to Li" (Leprosy), meaning wind in the Stomach brews for a long time, causing Ying Qi (Nutritive Qi) to become hot and turbid, resulting in the collapse of the nasal bridge and deterioration of complexion, with muscles gradually ulcerating. Mild cases present with body numbness, eye twitching, lockjaw, facial swelling, and ability to eat; Sheng Ma Wei Feng Tang (Cimicifuga Stomach Wind Decoction) is appropriate. These five conditions are collectively known as Wei Wind disease.
Po Shang Feng (Broken Injury Wind / Tetanus) occurs when skin and flesh are broken by trauma, allowing wind pathogens to invade, causing fever and swelling. The treatment method is similar to that for common cold. Furthermore, after various sores ulcerate, wind pathogens may invade due to deficiency. This condition is most acute and is often mistaken for ordinary ailments, leading to various complications and often untreatable cases. There are also cases where sore heat stagnates, forming white scabs, closing the wound, blocking Qi circulation, and generating wind from extreme heat. Or, using herbal washes allows dampness to enter through the wound, causing coma and heaviness. Or, using moxibustion or fire baking forces fire Qi inward, causing irritability and fever. One must distinguish: flat wounds without exudate indicate Po Shang Feng; wounds oozing yellow fluid indicate Po Shang Shi (Broken Injury Damp); red and swollen wounds indicate Po Shang Huo (Broken Injury Fire). The toxicity from these injuries is similar to Po Shang Feng. The pathogenesis spreads through meridians, blazing the True Qi, causing alternating chills and fever. Severe cases present with lockjaw, strabismus, rigid body, and opisthotonos, with death imminent. Treatment should follow the principles of Shang Han (Cold Damage), differentiating between exterior, interior, and half-exterior/half-interior patterns. He Jian said: For Tai Yang exterior patterns, use sweating methods; for Yang Ming interior patterns, use purgation; for Shao Yang half-exterior/half-interior patterns, use harmonization. However, if the affected area becomes red and swollen again, accompanied by coma and poor appetite, regardless of meridian involvement, use Shan Zha (Pangolin Scale) 1 qian, Wu Gong (Centipede) powder 0.5 qian, and She Xiang (Musk) one character dose, taken with strong decoction of Cong Bai (Scallion White) and Dou Chi (Fermented Soybean). Apply a paste of Cong Ti (Scallion Sap) and fried Fei Mian (Washed Flour) to the site. The text mentions only the Three Yang meridians because treating early according to the law cures wind pathogens in the Yang meridians. If it transmits to the Three Yin meridians, the condition is critical. Use Tian Ling Gai (Human Skull Cap) 1 qian, Shan Zha 0.5 qian, and She Xiang one character dose, powdered and taken with strong Cong Bai Dou Chi decoction. If abdominal fullness with spontaneous diarrhea, dry mouth and throat, curled tongue and retracted testicles, sweat beads on forehead not flowing, oily sweat on body, small eyes staring straight, and severe limb pain unrelated to the injury occur, these are death signs.
For Po Shang Feng with pathogen in the exterior, use Jiu Wei Qiang Huo Tang (Nine-Ingredient Notopterygium Decoction); for half-exterior/half-interior, use Xiao Chai Hu Tang; for profuse sweating with muscle spasms and convulsions, use Sheng Ma Tang plus Huang Qi (Astragalus Root). If excessive use of wind-dispelling herbs like Wu Gong causes spontaneous sweating, use Bai Zhu (Atractylodes Macrocephala Rhizome), Huang Qi, Fang Feng, and Sheng Gan Cao (Raw Licorice Root) decocted and taken warm. For constipation and dark scanty urine, or continuous sweating from hot medicines, rapid purgation is needed. First use Xiong Huang Tang (Ligusticum and Astragalus Decoction) two or three doses, then Da Xiong Huang Tang. If ineffective and spasms worsen, use Qiang Huo (Notopterygium Rhizome), Du Huo (Angelica Pubescens Root), Fang Feng, Xing Ren (Apricot Seed), and Di Yu (Sanguisorba Root) decocted in water frequently, named Juan Jing Tang (Spasm-Relieving Decoction). For fecal impaction, use bile suppository or honey suppository methods. For chronic weakness, nourish Blood with Si Wu Tang (Four-Substance Decoction) plus Gao Ben (Ligusticum Wallichii Rhizome), Fang Feng, Xi Xin (Asarum Root), and Bai Zhi (Angelica Dahurica Root). For sore Po Shang Feng with body pain, wind attacking causing spasms, itching, numbness, dizziness, and lockjaw, use Fang Feng, Gao Ben, Qiang Huo, Di Gu Pi (Lycium Bark), and Jing Jie Sui (Schizonepeta Flower Spike) powdered and taken with wine. For blocked scabs with internal heat generating wind, use Jiu Wei Qiang Huo Tang. For damp injury with thin pus, first use Chu Shi Tang (Dampness-Expelling Decoction) two or three doses, then Yi Wei Bai Zhu Gao (Single-Ingredient Atractylodes Paste) or wine infusion. For fire injury with redness/swelling, headache, fever, and irritability, use Xiong Huang Tang plus Bo He (Mint), Jing Jie, and Fang Feng; if ineffective, add Jiu Huang Lian (Wine-processed Coptis Rhizome) 4-5 fen, Hei Shan Zhi (Black Gardenia Fruit) 2 qian. If urination is difficult, combine with Dao Chi San (Directing Away Red Powder). For severe lockjaw, roast one Wu Gong, powder finely, rub teeth; salivation will release and consciousness return. Alternatively, use Zuo Long Wan (Left Dragon Pill). For swelling unable to drain pus, use Zhu Sha (Cinnabar), Nan Xing (Pinellia Tuber), Du Huo, Shan Zha, and Ren Zhi Jia (Human Nail) roasted and powdered, taken with wine twice or thrice. Externally, apply Nan Xing and Fang Feng powdered with Ginger Juice.
Shi Wan said: Broken injury differs significantly from ulceration. Trauma from metal or falls causes chills, fever, headache, facial swelling, chest oppression, floating-wiry pulses, or indistinct pulses. Transmission resembles Shang Han but is more severe, allowing surface-releasing methods. However, harsh wind-dispelling herbs should be avoided because blood vessels are damaged ("loss of blood precludes sweating"). Ulceration breaking open causes sudden swelling, insensitivity to pressure, generalized numbness,牵引 pain, chest fullness, confusion, wiry-thin or deficient-large indistinct pulses. Although wind-toxin attacks the body, surface-releasing drugs must not be used; sweating causes muscle twitching and spasms ("sores cannot be sweated, sweating causes spasms"). Mild cases: Cong Bai Dou Chi Tang plus Lin Qi Jia (Pangolin Scale), Bai Zhi, Wu Gong. Severe cases: Cong Bai Dou Chi Tang plus Huang Qi, Rou Gui (Cinnamon Bark), Yuan Zhi (Polygala Root), Fang Feng, Lin Qi Jia, Xi Jiao (Rhinoceros Horn). Critical cases: Wan Ling Dan (Ten-Thousand Spirit Pill) taken with Cong Chi decoction. Vomiting and inability to eat indicates wind-toxin attacking the Heart; urgently give Hu Xin San (Heart-Protecting Powder). Externally use Cong Yun (Scallion Fomentation). If constipated, do NOT use Xiong Huang Tang; use honey suppository only. As severity recedes, use Bao Yuan Tang plus Yuan Zhi, Rou Gui, Xi Jiao, Lin Qi Jia to resolve residual toxin, combined with Ren Shen (Ginseng Root) and Huang Qi to prevent stagnation. Tonification and purgation depend on individual constitution; flexibility in clinical practice is key.
[Diagnosis] Floating and weak pulse indicates Tai Yang; long and forceful pulse indicates Yang Ming; floating and wiry indicates Shao Yang; surging and rapid indicates Fire injury; deep and fine indicates Damp injury. Deficient-fine and choppy pulses are untreatable. Yu Hengde treated a man who broke his brow bone in a fight, developing Po Shang Feng with massive head/face swelling and fever. He used Jiu Wei Qiang Huo Tang to induce sweating and externally applied almond paste mixed with flour and fresh water to the wound. Swelling subsided, fever resolved, and he recovered. This method proved effective repeatedly.
