For all diseases where the pathogen is located in the diaphragm region, Gouti San (Melon Seed Powder) should be used to induce vomiting. If the exterior syndrome has resolved and the evil heat has entered the interior, knotting in the chest, causing mental irritability, fullness, hunger but inability to eat, slight coldness of the four limbs, and a pulse that is intermittently rapid, it is appropriate to use Gouti San to induce vomiting. Headache caused by Shanghan (Cold Damage) that persists for a long time can lead to loss of vision; this is due to retained phlegm in the chest and diaphragm. One should first employ emesis (inducing vomiting), followed by modified Baihu Tang (White Tiger Decoction).
When heat accumulates in the lower jiao (Lower Burner), purgatives such as Chengqi Tang (Gastro-Intestinal Replenishment Decoction) and Didang Tang (Defeat Stasis Decoction) can be used to purge the heat.
Combined disease of the three Yang channels: Abdominal fullness, heaviness of the body, difficulty in turning over, dry mouth, dirty complexion, delirium, and urinary incontinence. If sweating therapy is mistakenly applied, delirium will worsen; if purgation is mistakenly applied, it leads to cold extremities, sweating on the forehead, and subsequently jaundice. In such cases, Baihu Tang (White Tiger Decoction) is indicated.
Lianggan (Double Exposure) refers to the condition where symptoms of the Taiyang (Greater Yang) and Shaoyin (Lesser Yin) channels appear on the first day, Yangming (Bright Yang) and Taiyin (Greater Yin) on the second day, and Shaoyang (Lesser Yang) and Jueyin (Terminal Yin) on the third day. These are the syndromes of the first six channels. Xiao Chaihu Tang (Minor Bupleurum Decoction), Liangge San (Cooling Diaphragm Powder), Wuling San (Five Ingredient Powder with Poria), Tianshui San (Heavenly Water Powder), Tongsheng San (Universal Salvation Powder), Shuangjie San (Double Resolution Powder), and Da Chaihu Tang (Major Bupleurum Decoction) may be selected for use. If the heat intensity is severe and purgation is suitable, Sanyi Chengqi Tang (Three-One Gastro-Intestinal Replenishment Decoction) or a combination of Jiedu Tang (Detoxification Decoction) and Chengqi Tang (Gastro-Intestinal Replenishment Decoction) may be used.
Jing (Spasm) disease manifests as fever, abdominal fullness, trismus (lockjaw), head shaking, convulsions, inability to speak, neck stiffness, back rigidity, and opisthotonos (arching of the back). Alternatively, there may be eye pain, red eyes, closed eyes, or upward deviation of the eyes; warm feet; or erratic behavior. The pulse is deep, wiry, and slow, or tight. Absence of sweat is termed Gang Jing (Rigid Spasm); presence of sweat is termed Rou Jing (Soft Spasm). Generally, Sanyi Chengqi Tang (Three-One Gastro-Intestinal Replenishment Decoction) combined with Jiedu Tang (Detoxification Decoction) should be used to purge.
Regarding headache syndromes, regardless of whether they arise from mixed pathogens such as wind, cold, summerheat, or dampness, self-sweating headaches are all suitable for treatment with Baihu Tang (White Tiger Decoction), or adding Chuanxiong Rhizome (Chuanxiong) and Schizonepeta Spike (Jingjie) for better effect. Headaches that persist for a long time will inevitably lead to loss of vision; one should first induce vomiting to expel phlegm, then use modified Baihu Tang (White Tiger Decoction). For dizziness due to wind, rebellious phlegm, asthma, cough, and headache, Lingban Banxia Tang (Poria and Pinellia Decoction) is indicated; for headache and limb pain, Huanglian Jiedu Tang (Coptis Detoxification Decoction) is used; for headache and dry mouth, Guiling Ganlu Yin (Cinnamon and Atractylodes Sweet Dew Drink) is prescribed; for wind-disease-induced asthma, cough, and headache, Baihu Tang (White Tiger Decoction) combined with Banxia Jupi Tang (Pinellia and Tangerine Peel Decoction) is used; for wind-heat induced headache, mental restlessness, and confusion, Renshen Shigao Tang (Ginseng and Gypsum Decoction) is indicated; for Shanghan (Cold Damage) high fever, headache, and inability to lie down, Buwo San (Non-Sleep Powder) is used.
