凡治风之法，宜察浅深虚实及中经中脏之辨。盖中经者，邪在三阳，其病犹浅；中脏者
，邪入三阴，其病则甚。若在浅不治，则渐入于深；在经不治，则渐入于脏，此浅深之谓也
。又若正胜邪者，乃可直攻其邪；正不胜邪者，则必先顾其本，此虚实之谓也。倘不知此，
则未有不致败者。
一、大风大寒直中三阴致危者，必用《金匮》续命汤去石膏治之。若风寒在经，而头疼
恶寒，拘急身痛者，宜麻黄汤、麻桂饮随证加减主之。甚者亦宜续命汤。若头疼有汗恶风者
，宜桂枝汤，或五积散。若风邪在经，热多寒少，而为偏枯疼痛发热者，宜大秦艽汤主之。
甚者，愈风汤亦可。
一、风寒诸病，无非外感证也。如轻浅在肺者，则为伤风。稍深在表里之间者，则为疟
疾。留连经络者，则为寒热往来。遍传六经，彻内彻外者，则为伤寒、瘟疫。久留筋骨者，
则为风痹、痛风，或为偏风。风热上壅者，则为大头时毒。风湿相搏者，则为大风、疠风。
浮在肌肤者，则为斑疹、疮毒。感在岭南者，则为瘴气。凡此者皆外感风寒之病，俱有门类
，方论具载各条。舍此之外，但无表证者，均不得指为风也。
许胤宗治唐柳太后病风，脉沉欲脱，云∶服汤药无及矣。即以黄 防风煮汤数十斛，置
床下熏薄之。是夕果语，更药之而愈。
王克明治卢州王守道风噤不能语，以炽炭烧地热，洒以药汤，置病者于上，须臾小苏。
若此二者，以病至垂危，药不能及，亦治风之权变也。
In general, the treatment of wind diseases requires distinguishing the depth and superficiality of the pathogen, the deficiency or excess of healthy Qi (Zheng Qi), and whether the pathogen has invaded the meridians (Jing) or the zang-fu organs. Generally speaking, when the pathogen invades the meridians, it affects the Three Yang meridians, and the disease is relatively shallow; when the pathogen invades the zang-fu organs, it penetrates the Three Yin meridians, and the disease is severe. If a disease at a superficial level is not treated, it will gradually deepen; if a disease in the meridians is not treated, it will gradually enter the zang-fu organs. This refers to the distinction between depth and superficiality. Furthermore, if healthy Qi is strong enough to overcome the pathogen, one can directly attack the pathogen; if healthy Qi is insufficient to overcome the pathogen, one must first protect the root (healthy Qi). This refers to the distinction between deficiency and excess. Failure to understand these principles will inevitably lead to therapeutic failure.
1. In cases where severe wind and cold pathogens directly invade the Three Yin meridians causing critical conditions, one must use Xu Ming Tang (Cure Wind Decoction) from *Jin Gui Yao Lue* (Essential Prescriptions of the Golden Cabinet), removing Shi Gao (Gypsum Fibrosum). If wind-cold remains in the meridians, presenting with headache, aversion to cold, limb stiffness, and body pain, Ma Huang Tang (Ephedra Decoction) or Ma Gui Yin (Ephedra and Cinnamon Twig Drink) should be used, modified according to the specific syndrome. For severe cases, Xu Ming Tang is also appropriate. If there is headache accompanied by sweating and aversion to wind, Gui Zhi Tang (Cinnamon Twig Decoction) or Wu Ji San (Five Accumulations Powder) is suitable. If wind-pathogen remains in the meridians, with heat predominating over cold, presenting with hemiplegia, pain, and fever, Da Qin Jiao Tang (Large Notopterygium Decoction) is indicated. For severe cases, Yu Feng Tang (Wind-Extinguishing Decoction) may also be used.
1. Various diseases caused by wind and cold are essentially exterior syndromes. Mild cases affecting the Lung system constitute Shang Feng (Wind-Cold Invasion). Cases slightly deeper, situated between the exterior and interior, constitute Nue Ji (Malaria). Pathogens lingering in the meridians manifest as alternating chills and fever. Pathogens spreading through all six meridians, penetrating both inside and outside, constitute Shang Han (Cold Damage) or Wen Yi (Plague). Pathogens remaining long-term in the sinews and bones result in Feng Bi (Wind-Bi Syndrome), Tong Feng (Gout-like Pain), or Pian Feng (Hemiplegic Wind). Wind-heat congesting upwards results in Da Tou Shi Du (Big Head Plague). Wind-dampness intertwining results in Da Feng or Li Feng (Leprosy/Malignant Wind). Pathogens floating on the skin and muscles present as Ban Zhen (Macules and Papules) or Chuang Du (Sores and Toxins). Infections in the Lingnan region constitute Zhang Qi (Miasma). All these belong to exterior wind-cold diseases, each categorized under specific headings, with formulas and discussions detailed in their respective sections. Outside of these categories, any condition lacking exterior signs cannot be classified as a wind disease.
Xu Yinzong treated Empress Dowager Liu of the Tang Dynasty for wind disease. Her pulse was deep and nearly imperceptible. He stated, "Administering decoctions orally is no longer effective." Therefore, he boiled Huang Qi (Astragali Radix) and Fang Feng (Saposhnikoviae Radix) into dozens of hu (a unit of volume) of medicinal soup, placed it under the bed, and fumigated the patient with the steam. That evening, the patient indeed regained the ability to speak. After further medication, she recovered.
Wang Keming treated Wang Shoudao of Luzhou for wind disease resulting in trismus and inability to speak. He heated the ground with hot charcoal, sprinkled medicinal soup upon it, and placed the patient on top. The patient soon regained slight consciousness. These two cases illustrate that when a disease reaches a critical stage where oral medications cannot reach the site of action, such methods represent expedient variations (Quan Bian) in the treatment of wind diseases.
