Aversion to wind and spontaneous sweating are characteristics of Wind Strike (Zhong Feng, 中风). (Zhang Zhongjing refers to Wind Strike as Shang Feng, 伤风.) The body is hot, the head aches, and the disease severity is intense. The hands and feet are not cold, and there is mental restlessness. The facial color is normal, without a pale or ghastly appearance. (Explanation is found in the previous chapter.) A floating and moderate pulse is the sign of this syndrome. Sometimes, a large cun pulse and a weak chi pulse may be encountered. (Although the pulse of Shang Feng is floating and moderate, *Huo Ren Shu* states: there are cases with a weak chi pulse and a large cun-kou pulse. Zhang Zhongjing states: Yang [cun] is floating and Yin [chi] is weak. Floating Yang indicates spontaneous heat; weak Yin indicates spontaneous sweating.) Guizhi Tang (Cinnamon Twig Decoction), Baidu San (Poison-Expelling Powder), Duhuo (Radix Angelicae Pubescentis) and similar herbs should be selected for use. (*Huo Ren Shu* states: Medicines for treating Zhong Feng should include Guizhi Baidu San or Duhuo San.) For neck stiffness, Guizhi Jia Gegen Tang (Cinnamon Twig Decoction with Pueraria Root) is indicated. (Zhang Zhongjing states: In Taiyang disease, if there is stiffness in the neck and back, accompanied by sweating and aversion to wind, Guizhi Jia Gegen Tang should be administered.) For leakage of sweat (Lou Feng, 漏风), adding Fuzi (Radix Aconiti Lateralis Preparata) can achieve efficacy. (Zhang Zhongjing states: In Taiyang disease, after inducing sweating, if sweating continues unceasingly, accompanied by aversion to wind, difficulty in urination, slight rigidity of the four limbs, and difficulty in flexion and extension, Guizhi Jia Fuzi Tang should be administered.) How to distinguish between Shang Feng and Shang Han? The pulse for Cold pathogen is tight and choppy; the pulse for Wind pathogen is floating and moderate. Shang Han necessarily involves aversion to cold, whereas Shang Feng involves only aversion to wind. Shang Feng presents with spontaneous sweating, while Shang Han presents with no sweating. (Explanation is found in the previous chapter.)

Aversion to cold without restlessness, with slightly cold extremities. The pulse is floating and moderate but forceless. Aversion to wind with restlessness, with warm hands and feet. The pulse is tight, floating, and choppy. Shang Han unexpectedly presents with the pulse of Shang Feng, while Zhong Feng unexpectedly presents with the pulse of Shang Han. In such cases, Da Qing Long Tang (Great Blue Dragon Decoction) is appropriate. It harmonizes Wei (Defensive) and Ying (Nutritive), addressing both aspects. (Zhang Zhongjing states: In Taiyang Zhong Feng, if the pulse is floating and tight, with fever, aversion to cold, body pain, no sweating, and restlessness, Da Qing Long Tang should be administered. He also states: In Shang Han, if the pulse is floating and moderate, with no body pain but heaviness, occasionally alleviating, and without Shaoyin disease signs, Da Qing Long Tang should be administered. Zhong Feng typically presents with a floating-moderate pulse, but now it is floating-tight; Shang Han typically presents with a floating-tight pulse, but now it is floating-moderate. This represents Zhong Feng showing Cold pulses and Shang Han showing Wind pulses.) One must ascertain whether the patient has restlessness before administering this formula to ensure accuracy. If the pulse is faint, with spontaneous sweating and aversion to wind, misusing Da Qing Long Tang will lead to Jue Ni (Cold Reversal, 厥逆) and Jin Ti Rou Dong (Muscle Twitching, 筋惕肉瞤). (Zhang Zhongjing states: With a faint pulse, sweating, and aversion to wind, this formula must not be used. Administration leads to Jue Ni and muscle twitching, which constitutes an adverse reaction. Therefore, Wang Shi advocated using Guizhi Mahuang Ge Ban Tang [Half-Guizhi Half-Mahuang Decoction].)
