[Formula for Rubbing Teeth with Sour Plum to Open the Jaw]
Treats jaw lock (trismus) caused by wind-stroke (stroke). The Foot-Yangming Stomach Meridian passes through Jiache (ST6) and enters the teeth gaps. When invaded by Wind-Cold, mild cases present with trembling and jerking of the mandible, while severe cases present with jaw lock preventing mouth opening. There are also cases of wind-stroke where the mouth is open but cannot close; this indicates the tendons have already exhausted, which is untreatable.
Use *Semen Pruni Mume* (Wumei, 乌梅) to rub the gums. Once saliva flows out, the jaw will open.
This formula acts on the Foot-Yangming and Foot-Jueyin meridians. The sour flavor first enters the tendons; Wood overcomes Earth (sour belongs to Wood, the Yangming Stomach belongs to Earth), causing the jaw to become soft due to sourness and thus open.

[Lizhong Tang]
When Cold invades the exterior, sweating should be induced; when Cold invades the interior, warming should be applied. This is because the human body relies primarily on Yang Qi. The Classics state: "Yang Qi is like the sky and the sun; if it loses its proper function, lifespan is shortened and brilliance is lost." Cold is a Yin, chilling, and desolate energy. When Yin is excessive, Yang declines. When Yang is exhausted and Yin severed, death ensues. Zhang Zhongjing, in writing his medical books... [text missing]

Treats Taiyin disease from Cold Damage, presenting with spontaneous diarrhea without thirst, abundant cold, vomiting, abdominal pain, loose stools, and a deep, weak pulse; or cold limbs and tendon contracture; or chest binding (Jie Xiong) and vomiting roundworms; as well as cholera-like syndrome caused by Cold invasion. (Taiyin disease involves the Spleen meridian. Abdominal fullness with vomiting, inability to eat, spontaneous diarrhea with abdominal pain constitutes Taiyin disease. Spontaneous diarrhea with thirst indicates Heat; without thirst indicates Cold. Preference for vomiting, abdominal pain, and loose stools are all caused by deficiency-cold. When Cold penetrates to the exterior, hands and feet become cold and contracted; when Cold condenses in the interior, it leads to chest binding, diarrhea, and vomiting roundworms. Cholera is characterized by sudden turmoil due to disharmony between Yin and Yang, with either vomiting or diarrhea. There are both Cold and Heat patterns; if caused by Yin-Cold, this decoction is suitable. Diarrhea transmitted from the Three Yang meridians to the Yin meridians is Heat diarrhea; diarrhea directly struck by Yin-Cold into the Yin meridians is Cold diarrhea. Abdominal pain caused by external pathogens transmitting inward has intermittent pain; abdominal pain caused by internal Yin-Cold has unceasing pain, often urging defecation. The great abdomen belongs to Taiyin, the lower abdomen to Shaoyin, and the area below the navel to Jueyin. There are also cases complicated by food stagnation and phlegm. In diarrhea of the Three Yang meridians, there is fever; in Taiyin diarrhea, hands and feet are warm; in Shaoyin and Jueyin diarrhea, the body is cold. These are general principles.)

*Bai Zhu* (Fried on an east-facing wall earth. 2 liang), *Ren Shen*, *Gan Jiang* (Pao/processed), *Gan Cao* (Zhi/honey-fried. 1 liang). Take 4 qian per dose. For spontaneous diarrhea with abdominal pain, add *Mu Xiang*; for profuse diarrhea without pain, double the dosage of *Bai Zhu*; for thirst, double the dosage of *Bai Zhu* (*Bai Zhu* tonifies Qi and dries dampness, thereby generating fluids); for curling up in bed, heaviness, and unremitting diarrhea, add *Fu Zi* (indicating concurrent Shaoyin syndrome); for abdominal fullness, remove *Gan Cao* (sweet/cold nature causes fullness); for vomiting, remove *Bai Zhu*, add *Ban Xia* and ginger juice (*Bai Zhu* is sweet and cloying, while ginger and banxia disperse rebellious Qi); for palpitations/movement below the navel (Dong Qi), remove *Bai Zhu*, add *Gui Zhi* (*Bai Zhu* tonifies Qi, *Gui Zhi* drains Ben Tun/running piglet Qi); for palpitations, add *Fu Ling* (fluid retention causes palpitations, *Fu Ling* promotes urination and calms the heart); for Yin Jaundice, add *Yin Chen*; for Cold Chest Binding, add *Zhi Shi*. Equal parts of this formula made into honey pills are named Lizhong Wan. (Zhang Zhongjing said: After a major illness, frequent spitting that persists long is due to Cold in the stomach, treat with Lizhong Wan...)

This formula acts on the Foot-Taiyin Spleen meridian. *Ren Shen* tonifies Qi and benefits the Spleen, serving as the Sovereign drug; *Bai Zhu* strengthens the Spleen and dries dampness, serving as the Minister drug; *Gan Cao* harmonizes the middle and tonifies Earth, serving as the Assistant drug; *Gan Jiang* warms the Stomach and disperses Cold, serving as the Envoy drug. Since Spleen-Earth resides in the center, it is called Lizhong (Regulating the Middle). (Wang Haicang said: For incessant vomiting and diarrhea, where thirst is absent despite expectation, and the pulse is faint, fine, and weak, Lizhong Tang is indicated. The Classics also state: If purgatives are misused in Cold Damage leading to unremitting diarrhea, and the physician administers Lizhong Tang causing worsening diarrhea; Lizhong Tang regulates the Middle Jiao, but this diarrhea is in the Lower Jiao, treated with Chishi Zhi Yuyuliang Tang; if diarrhea persists, promote urination. Emperor Huizong of Song ate too much ice, developing a Spleen disorder. Imperial physicians were ineffective. He summoned Yang Jie, who administered Dali Lizhong Wan. The Emperor said: I have taken it many times. Jie said: The disease was caused by eating ice,臣...)

Three liang of this formula plus one *Fu Zi* is named Fuzi Lizhong Tang (can also be made into pills; i.e., Sini Tang added with Ren Shen and Bai Zhu): Treats Cold injury causing abdominal pain, body pain, and limb contracture. (Gradual injury is termed Shang; sudden strike is termed Zhong. There are distinctions among striking the Zang, Fu, collaterals, skin, flesh, sinews, and vessels. Treatment must distinguish severity: Mild cases use Buhuan Jin Zhengqi San added with Fuzi, or Fuzi Wuji San; Severe cases with umbilical/abdominal pain and cold limbs use Fuzi Lizhong Tang or Jiang Fu Tang. If invading the Liver, add Mugua; invading the Lung, add Sangbaipi; invading the Spleen, add Baizhu; invading the Heart, add Fuling). Adding *Zhi Shi* and *Fu Ling* to this formula, made into honey pills, is named Zhishi Lizhong Wan (Cui Xinggong): Treats severe Cold-Excess Chest Binding with high elevation of the chest/diaphragm, intolerable to touch, where Daxiexiong Tang failed. Cui said: This is deficiency and rebellion after purgation, Qi mechanism is unregulated, and toxin attacks upward. Qi and toxin bind in the chest. Use this pill to regulate Qi first, then treat other ailments. It works miraculously. Add Huafen for thirst, add Muli for spontaneous sweating. Removing *Gan Cao* from this formula and adding *Fu Ling*, *Chuanjiao*, and *Wumei* is named Lizhong Anhui Wan (Tao Zhongwen): Treats Cold-Stomach vomiting roundworms (Roundworms move with Sweet, so remove Gancao; they stop with Sour, so add Jiaomei; they subside with Pungent, so add Chuanjiao). Adding *Guizhi* and doubling *Gancao* to this formula is named Guizhi Renshen Tang (Zhang Zhongjing): Treats Sunyang exterior syndrome not resolved, followed by multiple purgations, leading to Heat-induced diarrhea, epigastric hardness/fullness, and unresolved exterior-interior complex. (To resolve exterior-interior pathogens, reliance is placed on Middle Qi for distribution. Thus, Lizhong Tang harmonizes the interior, while Guizhi resolves the exterior. It is named Guizhi rather than Lizhong to emphasize the principle of resolving the exterior first. Generally, Yang-Heat pathogen causes abdominal pain and dry throat; Yin-Cold pathogen causes abdominal fullness, vomiting, and diarrhea). Adding *Huanglian* and *Fu Ling* to this formula is named Lianli Tang: Treats diarrhea caused by Summerheat-Dampness injury (If externally affected by intense Summerheat and internally injured by raw/cold foods, this formula is indispensable). Adding *Chenpi* and *Fu Ling* to this formula is named Buzhong Tang: Treats diarrhea. For unremitting diarrhea, add Fuzi; for aversion to food and indigestion, add Sharen. Adding *Danggui*, *Baishao*, *Chenpi*, *Houpo*, and *Chuanjiao* to this formula, decocted with ginger, is named Wenwei Tang: Treats憂思郁结 (worry and thought stagnation), Qi stagnation in Spleen and Lung, distension rushing upward, and inability to eat. Adding *Huangqi*, *Baishao*, *Chenpi*, and *Huoxiang* to this formula is named Huangqi Tang (Haicang. Also derived from Lizhong principles). Adding *Qingpi* and *Chenpi* to this formula is named Zhizhong Tang: Treats the aforementioned syndromes with abdominal fullness, stifling sensation, and concurrent food stagnation...
