风寒暑湿，皆能中人。惟湿气积久，留滞关节，故能中非如风寒暑之有暴中也。
中湿之证，关节重痛，浮肿喘满，腹胀烦闷，昏不知人，其脉必沉而缓，或沉而微
细，宜除湿汤、白术酒。有破伤处因澡浴湿气从疮口中入，其人昏迷沉重，状类中
湿，名曰破伤湿，宜白术酒。
中气，因七情内伤，气逆为病，痰潮昏塞，牙关紧急。七情皆能为中，因怒而
中者尤多。大略与中风相似，风与气亦自难辨。风中身温，气中身冷。风中多痰涎，
气中无痰涎。风中脉浮应人迎，气中脉沉应气口。以气药治风则可，以风药治气则
不可。才觉中气，急以苏合香丸灌之，候醒，继以八味顺气散加香附三五钱，或木
香调气散。尚有余痰末尽平复，宜多进四七汤及星香散。若其人本虚，痰气上逆，
关隔不通，上下升降，或大便虚秘，宜用三和丹。
中食之证，忽然厥逆昏迷，口不能言，肢不能举，状似中风。皆因饮食过伤醉
饱之后，或感风寒，或着气恼，以致填塞胸中，胃气有所不行，阴阳痞隔，升降不
通，此内伤之至重者。人多不识，若误作中风、中气，而以祛风行气之药，重伤胃
气，其死可立而待。不若先煎姜盐汤探吐其食。仍视其风寒尚在者，以藿香正气散
解之。气滞不行者，以八味顺气散调之。吐后别无他证，只用平胃散加白术、茯苓、
半夏、曲 之类调理。如遇此卒暴之病，必须审问明白，或方食醉饱，或饮食过伤，
但觉胸膈痞闷，痰涎壅塞，气口脉紧盛者，且作食滞冶之。戴云∶人之饮食下咽而
入肝，由肝而入脾，由脾而入胃，因食所伤，肝气不理，故痰涎壅塞，若中风然，
亦有半身不遂者，肝主筋故也，治以风药则误矣。按复庵名医也，饮食下咽而先入
肝，于理难通，其必有谓矣。姑存之以俟问。
Wind, cold, summer-heat, and dampness can all invade the human body. Only when dampness accumulates over a long period and stagnates in the joints does it cause "Zhong Shi" (Dampness Strike), which differs from the sudden onset ("Bao Zhong") seen with wind, cold, or summer-heat.
The syndrome of Zhong Shi (Dampness Strike) presents with heavy and painful joints, edema, asthma, chest fullness, abdominal distension, irritability, and coma with loss of consciousness. The pulse must be deep and slow, or deep and faint/thin. It is suitable to use Chu Shi Tang (Dampness-Expelling Decoction) and Baizhu Jiu (Atractylodes Macrocephala Wine). If there is an open wound where dampness enters through the sore during bathing, causing coma and heaviness resembling Zhong Shi, it is named Po Shang Shi (Traumatic Dampness), and Baizhu Jiu (Atractylodes Macrocephala Wine) is suitable.
Zhong Qi (Qi Strike) is caused by internal injury from the Seven Emotions (Joy, Anger, Worry, Pensiveness, Sorrow, Fear, Fright), leading to rebellious Qi as the pathology. Symptoms include surging phlegm, stupor, blockage, and lockjaw. All seven emotions can cause Zhong Qi, among which those triggered by anger are particularly common. Generally, it resembles Zh Feng (Wind Strike), making it difficult to distinguish between Wind and Qi. In Wind Strike, the body is warm; in Qi Strike, the body is cold. Wind Strike involves much phlegm-saliva, whereas Qi Strike has none. In Wind Strike, the pulse is floating and corresponds to the Renying point (ST 9); in Qi Strike, the pulse is deep and corresponds to the Qikou point (LU 9). Treating Wind with Qi-regulating herbs is acceptable, but treating Qi with Wind-dispelling herbs is not. Upon suspecting Zhong Qi (Qi Strike), immediately administer Suhe Xiang Wan (Styrax Pill). After the patient regains consciousness, follow up with Ba Wei Shun Qi San (Eight-Ingredient Qi-Regulating Powder) plus Xiangfu (Cyperus Rhizome) three to five qian, or Muxiang Tiao Qi San (Costus Regulating Qi Powder). If residual phlegm remains unresolvied, it is advisable to take Sizhi Tang (Four-Seven Decoction) and Xingxiang San (Star Anise and Costus Powder) frequently. If the person is originally deficient, with rebellious phlegm-Qi causing Guan Ge (obstruction), dysfunction of ascending and descending, or deficiency-type constipation, San He Dan (Three-Harmony Pill) is suitable.
The syndrome of Zhong Shi (Food Strike) presents with sudden syncope, coma, inability to speak, and inability to move limbs, resembling Wind Strike. This is all due to excessive dietary injury, after drunkenness or overeating, or following exposure to wind-cold or emotional distress, causing food to fill and obstruct the chest. Stomach Qi fails to circulate, Yin and Yang become blocked, and ascending and descending mechanisms fail. This is the most severe form of internal injury. Most people do not recognize this condition. If mistakenly treated as Wind Strike or Qi Strike using wind-dispelling and Qi-moving herbs, the Stomach Qi will be severely damaged, and death will follow immediately. It is better to first decoct ginger-salt water to induce vomiting and expel the food. Observe if wind-cold remains; if so, resolve it with Huoxiang Zhengqi San (Patchouli Correcting Qi Powder). For stagnant Qi, regulate it with Ba Wei Shun Qi San (Eight-Ingredient Qi-Regulating Powder). If no other symptoms remain after vomiting, simply use Pingwei San (Peaceful Stomach Powder) added with Baizhu (Atractylodes Macrocephala Rhizome), Fuling (Poria), Banxia (Pinellia Rhizome), Qu (Medicated Leaven), etc., for regulation. When encountering such acute conditions, one must inquire thoroughly. If the patient has just eaten or drunk excessively, or suffered dietary injury, and feels chest diaphragm oppression, phlegm-saliva congestion, and a tight/full pulse at the Qikou point (LU 9), treat it temporarily as Food Stagnation. Dai Yun stated: When food is swallowed, it enters the Liver, then the Spleen, then the Stomach. Injury from food causes Liver Qi to fail to flow smoothly, leading to phlegm-saliva congestion resembling Wind Strike, and even hemiplegia, because the Liver governs the sinews. Using wind-dispelling herbs would be a mistake. Commentary: Fu An was a famous physician. The idea that food enters the Liver first upon swallowing is logically difficult to accept; he must have had specific reasoning. I preserve this record here for future inquiry.
