中风病出现发热症状，经过六七天仍未缓解且伴有烦躁不安，既有表证又有里证，口渴想喝水，但水喝进去就吐出来，这种情况叫做“水逆”。主治方剂为五苓散。
中风病发热，到了六七天本应当自愈。如果未自愈，出现烦躁，说明邪气仍在体表。口渴想喝水，说明邪气传入体内。如果体内热势严重，就能消耗水分，水喝进去就不会呕吐。如果体内热势轻微，就不能消耗水分，导致水液停积不散，饮水后就会吐出清水。因为是因为水饮导致呕吐，所以名叫“水逆”。给予五苓散，以调和表里，消散停积的水饮。
娄氏说：既然说是体内热势轻微，不能消耗水液，使用五苓散治疗，那么之前治疗烦躁和消渴症的效果就显得更加清晰明了。
在切脉之前，病人双手交叉捂住心口。医生于是教他试着咳嗽，但他不咳嗽，这一定是双耳失聪，听不见声音。之所以这样，是因为过度发汗导致正气虚弱所致。
发汗过多，导致亡阳，胸中阳气不足的病人，会双手交叉捂住心口。医生看到外在证候，知道是阳气不足。又通过让他试咳却不即咳的反应，判断出耳聋。由此可知阳气虚损确凿无疑。耳聋是因为阳气虚弱，精气不能上通于耳窍所致。
王三阳说：诊治此病，应当经常思考少阳病的柴胡汤证，只是病情的轻重程度有所不同罢了。
发汗之后，如果饮水过多，必然会导致气喘。如果用冷水浇洗身体，也会导致气喘。
气喘属于肺系疾病。饮水过多导致气喘，是因为饮用冷饮损伤了肺气。因用冷水浇洗身体而导致气喘，是因为形体受寒损伤了肺气。
发汗之后，水药无法入口，这是逆证。如果再次发汗，必然导致呕吐和下利不止。
发汗之后，水药无法入口，称为吐逆。这是因为发汗导致亡阳，胃中虚冷。如果再次发汗，则会进一步损耗阳气，使胃气极度虚弱，因此出现呕吐和下利不止。
发汗、催吐或泻下治疗后，出现虚烦不得安睡的症状。如果病情加重，必然会出现翻来覆去、坐卧不安，心中懊恼郁闷。主治方剂为栀子豉汤。
发汗、催吐或泻下治疗后，邪热乘虚侵入胸中，称为“虚烦”，这属于热证。胸中烦热郁闷而不得发散，就是这种情况。热气伏留于体内的喜欢睡觉；如今热气浮越于上，扰乱阳气，所以不得安睡。心恶热，热势严重时必然导致神志昏乱。因此病情严重者，会反复颠倒而不安，心中懊恼郁闷。“懊恼”一词，通俗说法叫“鹘突”（糊涂不清）。《内经》说：病位在高处的，采用涌吐的方法祛除邪气。给予栀子豉汤，以涌吐胸中的邪气。
Fuling (Poria, two liang, sweet flavor, neutral nature) Guizhi (Cinnamon Twig, two liang, peeled, pungent flavor, hot nature) Shengjiang (Fresh Ginger, three liang, sliced, pungent flavor, warm nature) Gancao (Licorice Root, one liang, sweet flavor, neutral nature)
The above four herbs. Decoct with four sheng of water, reduce to two sheng. Remove the dregs. Divide into three doses and take warm.
The sweetness of Fuling (Poria) and Gancao (Licorice Root) benefits the body fluids and harmonizes the Wei Qi (Defensive Qi). The pungency of Guizhi (Cinnamon Twig) and Shengjiang (Fresh Ginger) assists Yang Qi and releases the exterior.
In Wind-Strike (Zhong Feng) with fever, if unresolved after six or seven days accompanied by vexation, presenting both exterior and interior signs, thirst with desire to drink water but vomiting immediately upon ingestion, this is named Water Reversal (Shui Ni). It is primarily treated with Wuling San (Five-Ingredient Powder with Poria).
Wind-Strike with fever should resolve by the sixth or seventh day. If it does not resolve and vexation occurs, the pathogen remains at the exterior. Thirst with desire to drink indicates the pathogen has transmitted to the interior. If interior heat is severe, it can consume water, so drinking will not cause vomiting. If interior heat is mild, it cannot consume water, leading to stagnation and accumulation; thus, drinking causes vomiting of clear fluid. Because the vomiting is caused by water retention, it is named Water Reversal. Administer Wuling San (Five-Ingredient Powder with Poria) to harmonize the exterior and interior and dissipate retained fluid.
Lou stated: Since it is said that interior heat is mild and cannot consume water, using Wuling San clarifies the efficacy of previous treatments for vexation and excessive thirst.
Before taking the pulse, the patient crosses their hands over the heart. The physician instructs them to try coughing, but they do not cough. This indicates bilateral deafness and inability to hear. This occurs because excessive sweating has depleted the healthy Qi.
Excessive sweating leads to loss of Yang. Patients with insufficient Yang Qi in the chest cross their hands over the heart. Observing these external signs, the physician knows Yang Qi is insufficient. By testing for cough and noting the absence thereof, deafness is confirmed. Thus, Yang deficiency is clearly established. Deafness results from deficient Yang Qi, preventing Essence and Qi from ascending to the ears.
Wang Sanyang stated: When treating this condition, one should constantly consider the Shaoyang syndrome (Lesser Yang Syndrome) Chai Hu Tang (Bupleurum Decoction) pattern, though the severity differs.
After sweating, if water intake is excessive, wheezing (Chuan) will inevitably occur. Washing the body with cold water also causes wheezing.
Wheezing is a lung disease. Wheezing due to excessive water intake is caused by cold drinks injuring the Lung. Wheezing due to washing with cold water is caused by external cold injuring the Lung.
After sweating, if water and medicine cannot be taken orally, this is a counterflow (Ni) syndrome. If sweating is induced again, it will inevitably lead to continuous vomiting and diarrhea.
After sweating, if water and medicine cannot be taken orally, it is called vomiting and counterflow. This is due to sweating causing loss of Yang and cold deficiency in the Stomach. If sweating is induced again, it further damages Yang Qi, causing extreme deficiency of Stomach Qi, hence continuous vomiting and diarrhea.
After sweating, vomiting, or purging, deficiency vexation occurs with insomnia. If severe, the patient tosses and turns restlessly, feeling deeply troubled and stifled in the chest. Zhi Zi Chi Tang (Gardenia and Fermented Soybean Decoction) is primarily indicated.
After sweating, vomiting, or purging, pathogenic heat enters the chest due to deficiency, termed "deficiency vexation," which is a heat syndrome. Vexation, heat, depression, and stifling in the chest without dispersion constitute this condition. Heat lurking internally favors sleep; now heat floats upward, disturbing Yang Qi, causing insomnia. The Heart dislikes heat; severe heat leads to mental confusion. Therefore, in severe cases, the patient tosses and turns restlessly, feeling deeply troubled and stifled. "Ao Nao" (deeply troubled) is colloquially known as "Hu Tu" (muddled/confused). The *Nei Jing* states: Where the pathology is high, use emesis to expel the pathogen. Administer Zhi Zi Chi Tang (Gardenia and Fermented Soybean Decoction) to emetic the pathogen from the chest.
