Zhongqi (Qi Stagnation/Strike), caused by internal injury from the Seven Emotions (Joy, Anger, Worry, Thought, Sorrow, Fear, Fright). The disease arises from rebellious Qi, manifesting as flooding phlegm, unconsciousness and obstruction, and lockjaw. Although all Seven Emotions can cause this Qi disturbance, those triggered by anger are particularly common. The symptoms are generally similar to Zhongfeng (Wind Strike), making it difficult to distinguish between Wind and Qi pathologies. Treating Wind with Qi-regulating herbs is acceptable, but treating Qi disorders with Wind-dispelling herbs is not. Upon the initial sensation of Zhongqi, administer Suhexiang Wan (Styrax Pill) immediately. After the patient regains consciousness, follow up with Bawei Shunqi San (Eight-Ingredient Qi-Smooth Powder) or Tiaoqi San (Qi-Regulating Powder). Zhongqi resembles Zhongfeng; the distinction lies in the fact that in Wind Strike the body is hot, whereas in Qi Strike the body is cold. After regaining consciousness, if residual phlegm remains and the body has not fully recovered, Siqi Tang (Four-Seven Decoction) and Xingxiang San (Star-Aromatic Powder) should be administered frequently. If the patient inherently has deficiency with phlegm, with rebellious Qi causing blockage at the diaphragm, obstructing the ascending and descending of Qi, or experiencing constipation due to deficiency, Sanhe Dan (Three-Harmony Pill) should be used. This approach applies to various Qi stagnation conditions, not solely Zhongqi.

The syndrome of Zhonghan (Cold Strike) presents with rigidity of the body, lockjaw with inability to speak, trembling of the four limbs, aversion to cold (Shasha Ehan), slight fever (Xixi Refa), or sudden vertigo. This is caused by being struck by Cold Toxin. Initially, administer Suhexiang Wan mixed with wine. For mild cases, administer Wuji San (Five Accumulations Powder) with added Cyperi Rhizoma (Xiangfu, 1 qian) and Moschus (Shexiang, a small amount); for severe cases, use Jiangfu Tang (Ginger and Aconite Decoction). If the patient gradually revives, the body warms up, and speech resumes, inquire about other accompanying symptoms after a short while. If accompanied by Qi attack causing stabbing pain, add Aucklandiae Radix (Muxiang, 0.5 qian) to Jiangfu Tang; if accompanied by Qi stagnation leading to numbness, add Saposhnikoviae Radix (Fangfeng, 1 qian); if accompanied by Dampness causing swelling and pain, add Atractylodis Macrocephalae Rhizoma (Baizhu, 1 qian); if tendons and vessels are pulled tight, add Chaenomelis Fructus (Mugua, 1 qian); if joint pain occurs, add Cinnamomi Ramulus (Guizhi, 2 qian).

The syndrome of Zhongshu (Summerheat Strike) manifests as a greasy face, chest oppression, fainting, unconsciousness, spontaneous cold sweat, slightly cold hands and feet, vomiting or diarrhea, wheezing, or fullness. One must absolutely avoid using cold water or highly cooling agents. Instead, Xiaoshu San (Summerheat-Relieving Powder) can be administered mixed with water. Alternatively, Laifu Dan (Reviving Life Pill) powder can be combined with Suhexiang Wan and administered with decoction. Or, Laifu Dan powder can be administered with decoction. Once the patient slightly revives, Xiangru Yin (Elsholtzia Decoction) should be used. Boil Elsholtziae Herba (Xiangru, 麻黄 is often associated but here refers to Elsholtzia in this context, specifically Elsholtzia splendens or similar aromatic herb) until cooked, remove dregs, and add a small amount of Moschus (Shexiang) for oral administration. Alternatively, insert garlic flesh into the nose, or crush garlic and administer the water solution. This is because Summerheat toxicity injures the person, with external Yin cold and internal Yang heat. Most summerheat remedies contain warming agents, such as Zingiberis Rhizoma (Shengjiang, Ginger) and Cinnamomi Cortex (Rougui, Cinnamon) in Dashun San; Eugeniae Caryophyllati Flos (Dingxiang, Clove) in Pipaye Ye San; and Elsholtziae Herba (Xiangru) in Xiangru Yin. Xiangru is pungent and warm; garlic is also pungent and warm. Moreover, garlic has a strong odor capable of opening orifices. Generally, substances with extreme odors or aromas can open orifices.

Upon initially feeling summerheat strike, immediately apply heated roof tiles, or cloths dipped in hot water, alternating to moxa/iron the epigastrium, abdomen, and below the umbilicus. Urgently administer Erqi Dan (Two-Qi Pill) powder mixed with decoction.

A guest once suffered from deep summerheat strike with confusion, cold extremities, profuse cold sweat like rain, nakedness desiring to jump into water, and overflowing salivary foam. This indicated deep summerheat strike with separation of Yin and Yang, which is difficult to cure. There is also a "Summerheat Journey" syndrome, which resembles summerheat strike but is milder, characterized by desire to sleep and reluctance to speak. For excess patterns, use Xiangru Yin with added Coptidis Rhizoma (Huanglian, 1 qian); for deficiency patterns, use Xingxiang Yin with added Elsholtziae Herba (Xiangru, 1 qian). After revival, if cold sweat persists, extremities remain cold, and there is irritability, oppression, and excessive thirst, use Xiangru Yin. If after revival, the physician over-administered cooling agents, causing persistent vomiting and diarrhea, external heat with internal cold, irritability, excessive thirst, and desire to undress, resembling Taiyang disease (Shaoyin/Shanghan pattern), this is Yin Excess repelling Yang. Warming herbs should be used: Xiangru Yin with added Aconiti Lateralis Radix Praeparata (Fuzi, Prepared Aconite Root), taken after soaking in cold liquid. For thirst, Suopi Yin (Spleen-Constricting Drink) with added Fuzi, also taken after soaking in cold liquid.
