The Da Cheng Qi Tang (Great Order the Qi Decoction) from *Jin Gui Yao Lue* is used to treat: patients with stiff body, distended head, locked jaw unable to speak, inability to lie flat with back touching the bed (lying without back contact), cramped and urgent legs, and even teeth grinding together. In such cases, this formula may be administered.
See the original text of this formula for details.

Commentary: This is a medication for the Yangming channel. The Yangming channel governs all sinews (tendons and fascia). If pathogenic factors of wind, cold, dampness, or heat enter the Stomach, causing the failure of fluids to circulate, the sinews lose nourishment. Therefore, it is urgent to use this decoction to purge.

*Xuan Ming Lun Fang* states: For conditions presenting with eyes closed, locked jaw, back stiffness resembling a bow, body swaying while lying down, and convulsions of hands and feet, it is generally appropriate to purge using San Yi Cheng Qi Tang (Three-One Order the Qi Decoction). This follows the same principle. However, unless one carefully differentiates the syndrome and confirms the presence of interior excess-heat, it should not be used lightly.

Fang Feng Dang Gui San (Saposhnikovia and Angelica Decoction) from *Nan Zhi* is used to treat patients who, after excessive sweating, develop fever, shaking of the head and face, sudden locked jaw, and opisthotonos (back arching backward). It is appropriate to employ methods to dispel wind and nourish blood.
Ingredients: Fangfeng (*Radix Saposhnikoviae*), Danggui (*Radix Angelicae Sinensis*), Chuanxiong (*Rhizoma Chuanxiong*), Dihuang (*Radix Rehmanniae Praeparata*) (each 1 liang).
Preparation and Administration: Coarsely crush the herbs. Take 1 liang per dose, decoct in water, and drink.

Respectfully noted: For individuals suffering from excessive sweating or internal deficiency of qi and blood, medication should be prescribed according to the specific syndrome. Ancient formulas often lack detailed records for such situations. This formula is recorded here merely to illustrate the intent. As for drugs that disperse wind-cold and unblock meridians, there are many; various warming drugs for treating yin collapse in *Huo Ren Shu*, and meridian-specific prescriptions in *Nan Zhi*, are not included here, aiming to explore the original intent of this book.

*Nei Jing* states: Wind qi travels along the Taiyang channel through the various shu points, dispersing between the muscle intervals. It interferes with Wei Qi (Defensive Qi), obstructing its pathway, thereby causing muscles to ulcerate. When Wei Qi stagnates and fails to circulate, the flesh becomes insensible (numb). Leprosy (Li Feng) arises from excessive heat in Ying Qi (Nutritive Qi) and Wei Qi, leading to turbid qi. This causes the nasal bridge to collapse, complexion to deteriorate, and skin to ulcerate. When wind-cold lodges in the vessels and does not depart, the disease is called Li Feng (Leprosy).

*Nei Jing* also says: In severe wind diseases characterized by heavy joints and loss of eyebrows and beard, it is termed Da Feng (Great Wind). Acupuncture at the muscle spaces induces sweating for one hundred days; acupuncture into the bone marrow induces sweating for one hundred days; draining the stagnant heat of Ying Qi. After one hundred days, when eyebrows and beard regrow, needling should cease. This is because the stagnant heat has been cleared, Yin Qi has recovered internally, leading to profuse sweating and regeneration of hair. *Ling Shu* states: For patients with Li Feng, repeatedly prick the swollen areas. After initial pricking, use a sharp needle to puncture the site, pressing out evil qi until the swelling subsides. Maintain regular dietary habits and avoid foods that might trigger the disease.

*Bing Ji* cites *Nei Jing*: "Wind entering the pulse becomes Leprosy," commonly known as Lai Bing (Leprous Disease). First, consume Hua Pi San (Birch Bark Powder), increasing the dosage gradually over five to seven days. Then, moxa the Chengjiang point (CV24) seven times. If the moxibustion blister is mild, apply moxa again; wait for the blister to heal before applying moxa three more times. Thereafter, administer Er Sheng San (Two-Sages Powder) to clear heat and expel wind pathogens from the blood. Abstain from sexual activity for three years. Discontinue herbal medicine and moxibustion upon recovery. *Shu Lei Xiang Xing* describes this as a method for treating Lung Wind. However, this disease is not confined to the Lung organ; it is called Lung Wind because it manifests on the nose. Nasal swelling, redness of the tip, enlargement, and ulceration occur due to blood following qi transformation. When qi fails to distribute, blood accumulates; when blood accumulates, flesh rots and worms are generated. The generation of worms is governed by the Jueyin Liver Wood. Jueyin belongs to Wind-Wood and governs the production of five types of worms. This is because excessive fire in the Triple Burner Shaoyang controls Metal (Lung); when Metal is weak, Wood overacts upon it. One should use agents that drain fire and promote the flow of wind pathogens, so that worms will naturally not generate. Thus, the nature of blood-heat in this disease is evident. Treatment should involve gentle purgation and drainage. One may use Sheng Ma Tang (Cimicifuga Decoction) from the Bureau Formulary to deliver Qian Shi's Xie Qing Wan (Drain Green Pill). Other symptoms should be treated according to their respective meridians.

Commentary: In Leprosy, the skin, hair, blood, and vessels are affected first. These two aspects are governed by Ying and Wei Qi, hence it is referred to as Lung Wind. Regarding internal necrosis and worm generation, these belong to the Yangming and Jueyin systems. Therefore, the medications used primarily vent Lung Qi and eliminate heat pathogens in the blood level. Moxibustion on the Chengjiang point, which is the intersection of the Yangming and Ren Mai (Conception Vessel), serves to unblock blood vessels and disperse wind.
