[Outline] Zhang Zhongjing said: After sweating therapy, if the patient experiences palpitations below the umbilicus and shows signs of impending Ben Tun (Rushing Pig disease), it should be treated with Fuling Guizhi Gancao Dazao Tang (Poria, Cinnamon Twig, Licorice, and Jujube Decoction).
If burning needles are used to induce sweating, and the needle site becomes cold, resulting in nodular redness, Ben Tun will inevitably occur. If Qi rushes from the lower abdomen up to the heart, moxibustion (one cone) should be applied to each nodule, and Guizhi Jia Gui Tang (Cinnamon Twig Decoction with Added Cinnamon Twig) should be administered.
In Yangming disease, if the pulse is floating and tight, accompanied by dry throat and bitter taste, abdominal fullness and wheezing, fever and sweating, aversion to cold replaced by aversion to heat, and heavy body, and if purgation is mistakenly applied, the stomach becomes empty. This allows pathogenic factors to disturb the diaphragm, causing mental restlessness and stifled sensation, with a coating on the tongue. In such cases, Zhizi Chi Tang (Gardenia and Fermented Soybean Decoction) should be used.
[Commentary] Xu Bin stated: The first clause discusses extreme deficiency of Ministerial Fire, where Kidney pathogenic factors slightly move and threaten the Heart, leading to Ben Tun. Sweat is the fluid of the Heart; thus, sweating leads to Heart deficiency. Unless residual pathogens invade the Kidneys during sweating, why would there be palpitations below the umbilicus? Since palpitation indicates Kidney pathogen movement, this signals impending Ben Tun. Therefore, Poria is combined with Cinnamon Twig and Licorice to specifically attack Kidney pathogens, while Jujube alone soothes the Stomach. It seems less concerned with exterior pathogens because after sweating, exterior pathogens are few, and since it is only "impending," the force is weak. Thus, by leaching out dampness and strengthening Earth, Yin Qi naturally declines, and Ganlan Shui (Water Stirred Vigorously) aids its downward movement. The second clause states that residual Taiyang pathogens remain, complicated by Ben Tun and nodules, requiring internal and external treatment. Taiyang disease was already sweated, yet burning needles were used again because Taiyang pathogens remained. However, burning needles causes fright, triggering Ben Tun Qi, so Qi rushes from the lower abdomen to the heart. Treating residual pathogens and attacking rushing Qi is relatively easy. But since the needle site is cold with red nodules, combined treatment is difficult. Thus, Guizhi Tang treats Taiyang pathogens, added Cinnamon Twig attacks Ben Tun Qi, and red nodules are treated externally with moxibustion, achieving both goals. This is because there is no abdominal pain or alternating chills and fever, indicating the disease is exclusively in the Taiyang channel.
Shen Jin'ao's Note: These three clauses belong to Dong Qi (Moving Qi). The first clause, palpitations below the umbilicus, is Kidney Water overcoming Heart Fire upward. "Impending" means not yet manifested. Preemptive treatment is needed. The second clause involves unsmooth Yang Qi, prevailing Yin Qi, and condensed Cold Pathogens causing red nodules, which is a sign of Ben Tun; Qi rushing from the lower abdomen to the heart is the manifestation of Ben Tun. In short, palpitations below the umbilicus indicate Water Pathogens attempting to invade the Heart via deficiency, so Poria corrects this, preventing Ben Tun. Qi rushing from the lower abdomen indicates Wood Pathogens carrying guest pathogens threatening the Heart, so adding Cinnamon Twig pacifies Wood, eliminating Ben Tun. One is interior and unmanifested; the other is exterior and manifested. Hence, treatments differ. The third clause involves an empty Stomach due to mistaken purgation. Pathogens lodging in the Upper Jiao cannot be removed by purgation, so guest pathogens disturb the Diaphragm.
[Outline] Zhang Zhongjing said: If Dong Qi is on the right, sweating is contraindicated. Sweating will cause epistaxis and thirst, severe mental distress, and vomiting water upon drinking. If Dong Qi is on the left, sweating is contraindicated. Sweating will cause dizziness, incessant sweating, and twitching of muscles and flesh. If Dong Qi is above, sweating is contraindicated. Sweating will cause Qi to rush upward, striking the heart directly. If Dong Qi is below, sweating is contraindicated. Sweating will result in inability to sweat, severe mental agitation, painful joints, vertigo, aversion to cold, vomiting after eating, and food failing to pass forward.
[Commentary] Xu Shuwei stated: Dong Qi refers to the throbbing sensation in the abdomen. Patients initially have five accumulations in the abdomen, either above, below, left, or right. Upon contracting cold damage, new pathogens clash with old ones, causing pain and throbbing, named Dong Qi. Generally, for deficiency patterns, Lizhong Tang (Regulate the Middle Decoction) with Bai Zhu removed and Gui Zhi added is used; for heat patterns, Chaihu Guizhi Tang (Bupleurum and Cinnamon Twig Decoction) is used.
Li [Name Missing] stated: Among the five accumulations, only Ben Tun rushing from below the umbilicus to the heart is most urgent. Guizhi Tang with double the amount of Gui Zhi is effective.
Cheng Wuji stated: How to understand Dong Qi in cold damage? Dong Qi is the throbbing movement within the abdomen. When Zang Qi is disordered, it manifests around the four sides of the umbilicus according to its associated organ, throbbing vigorously. The Nan Jing states: Liver internal syndrome has moving Qi to the left of the umbilicus, hard and painful upon pressure; Heart internal syndrome has moving Qi above the umbilicus, hard and painful upon pressure; Lung internal syndrome has moving Qi to the right of the umbilicus, hard and painful upon pressure; Kidney internal syndrome has moving Qi below the umbilicus, hard and painful upon pressure. This is the activation of abdominal climate due to disordered Zang Qi. Dong Qi corresponds to Zang organs, all indicating true Qi deficiency. Even if there are symptoms requiring attack from exterior or interior, purgation is contraindicated. Moreover, Spleen internal syndrome has moving Qi at the umbilicus. The Classics specifically state: Moving Qi at the four sides of the umbilicus prohibits sweating and purgation. It does not mention Spleen syndrome having moving Qi at the umbilicus because the Spleen is the Central State, guiding the Stomach to distribute fluids. Sweating, vomiting, and purging all affect the Spleen first. How much more so if the Spleen itself activates Dong Qi? Therefore, it is specifically omitted. In cold damage, observing external symptoms is crucial, not just visible pulses, but obtained through inquiry. Sweating, vomiting, and purging must be examined carefully. Taking Dong Qi as an example, others can be inferred.
[Outline] Zhang Zhongjing said: If Dong Qi is on the right, purgation is contraindicated. Purgation will deplete internal fluids, causing dry throat and nose, dizziness, and palpitations. If Dong Qi is on the left, purgation is contraindicated. Purgation will cause abdominal cramping, inability to eat, worsened Dong Qi, and even if there is body heat, the patient desires to curl up when lying down. If Dong Qi is above, purgation is contraindicated. Purgation will cause hot palms and agitation, floating coldness on the body, spontaneous sweating of hot sweat, desire to pour water on oneself. If Dong Qi is below, purgation is contraindicated. Purgation will cause abdominal fullness, dizziness upon sudden rising, passage of undigested food after eating, and epigastric痞 (fullness/stuffiness).
[Commentary] Li [Name Missing] stated: For Dong Qi on the right, sweating is contraindicated. Initially use Wuling San (Five-Ingredient Powder with Poria), then Zhuye Shigao Tang (Bamboo Leaf and Gypsum Decoction). Purgation is contraindicated; use modified Zhuye Shigao Tang. For Dong Qi on the left, sweating is contraindicated. Initially use Fangfeng Baizhu Muli Tang (Saposhnikovia, Atractylodes, and Oyster Shell Decoction); after sweating, use Jianzhong Tang (Establish the Middle Decoction). Purgation is contraindicated. Initially use Gancao Ganjiang Tang (Licorice and Dried Ginger Decoction), then Xiaojianzhong Tang (Minor Establish the Middle Decoction). For Dong Qi above, sweating is contraindicated. Use Ganligengen Tang (Tamarisk Root Decoction). Purgation is contraindicated; use modified Zhuye Shigao Tang. For Dong Qi below, sweating is contraindicated. Initially use Dajupi Tang (Large Tangerine Peel Decoction), then Xiaojianzhong Tang. Purgation is contraindicated; treat with Gancaoxie Xin Tang (Licorice and Heart-Purging Decoction).
Wei Litong stated: Cheng Wuji’s commentary attributes Right Lung, Left Liver, Upper Heart, Lower Kidney to Dong Qi, citing Nan Jing to attribute them all to Qi deficiency. This is correct. However, how can Qi deficiency produce movement? And why specifically at the four directions of the umbilicus? The umbilicus stores congenital Qi. When Qi is sufficient, it is firm and stable; when deficient, it shakes and moves. Like water in a bottle: full, it doesn't shake; empty, it shakes and makes noise. Similarly, intestinal borborygmus illustrates this principle. Qi is one, so why attributed to four Zang organs? This shows Qi at the umbilicus connects to Zang organs as congenital Yuan Qi. Deficiency here indicates dysfunction in the corresponding Zang Qi based on location. Dysfunction means absence, absence means insufficiency—simply Qi failing to reach. Cheng’s note cites Nan Jing saying "hard upon pressure," implying not just deficiency but pathogenic occupation. What pathogen? Cold Pathogen. Qi insufficiency and Yang deficiency allow Yin pathogens to intrude and mix. This further shows four Zang Qi failing to open and scatter, indicating rebellion in the local area and incompetence of the "officials" (Zang Qi). Sweating in deficiency is strictly prohibited, especially with accumulations. Sweating increases deficiency, causing latent Yin pathogens to rise. Each direction (left, right, upper, lower) has specific complications. Observable Dong Qi clarifies these prohibitions. All stem from congenital Qi deficiency and weak Zang Qi, showing Dong Qi at the four sides of the umbilicus as an early sign. Mistaken purgation without clear diagnosis leads to complications similar to, yet slightly different from, those of mistaken sweating.
