Mengshi Guntan Wan (Lapis Aureus Rolling Phlegm Pill) is a drastic formula for treating severe phlegm due to excess heat; it should not be used in cases of deficiency-cold.
Huangqin (Scutellariae Radix, 8 liang), Dahuang (Rhei Radix et Rhizoma, steamed with wine, 8 liang), Chenxiang (Aquilariae Lignum Resinatum, avoid fire, 5 qian), Mengshi (Calamina, calcined with saltpeter, buried in the ground for seven days, 1 liang).
Grind the above four herbs into fine powder, make pills with water, size like Sichuan pepper seeds. Use according to the patient's constitution. Take one mouthful of warm water to swallow, then lie supine immediately, allowing the medicine to descend slowly. Do not eat, drink, rise, move, or speak for half a day. Wait until the medicinal qi gradually descends from the stomach to the large and small intestines before resuming activity and diet. After taking the medicine, if there is a feeling of thick, sticky obstruction in the throat, this is due to the conflict between the medicinal power and the pathogen, causing phlegm-qi to surge upward. Shortly after, when the medicinal power reaches its destination, it will gradually expel the foul matter into the abdomen and intestines, with efficacy as swift as an echo.

Zhimi Fuling Wan (Finger-Confusing Poria Pill) treats retained phlegm and hidden fluid retention in the Middle Jiao.
Banxia (Pinelliae Rhizoma, processed, 2 liang), Fuling (Poria, 1 liang), Zhike (Aurantii Fructus Immaturus, 5 qian), Fenghuaxiao (Natrii Sulfas Exsiccatus, 2.5 qian).
Grind the above four herbs into powder, use ginger juice to make paste for pills.
[Note] The Classic says: "When fluids enter the Stomach, their essence circulates and overflows, moving upward to the Spleen." "Circulate" refers to operation; "overflow" refers to seepage; "move upward" refers to distribution; "essence" refers to the essence transformed from water. This means that the essence of water transformed in the Stomach circulates, seeps outside the intestines and stomach, and moves upward to be distributed by the Spleen. It also says: "The Spleen scatters essence, which returns upward to the Lung." This means the clear part of water rises, like rain and dew in the sky. It also says: "Regulating the water passages, sending downward to the Bladder." This means the turbid part of water descends, like rivers on earth. All these describe water transforming from turbid to clear, moving from Fu organs to Zang organs; from clear to turbid, moving from Zang organs to Fu organs, representing the circulation of water. It also says: "Water essence distributes in four directions, running through the five meridians." This means water originates from the Spleen, distributes around the four Zang organs, and runs parallel through the five meridians. All these describe water nourishing internal Zang and Fu organs externally and moistening the hundred bones, showing the subtle transformation of water. If this were the case, how could there be phlegm? If dietary habits are irregular and the Middle Jiao is disharmonious, water essence does not seep outward but goes directly down to the Large and Small Intestines, causing diarrhea. If the Sanjiao fails to transport, and Qi fails to steam and transform, the clear part of water does not ascend, and the turbid part does not descend. Essence transforms into water, leading to internal retention causing distension, external flooding causing edema, upward attacking causing panting, and downward accumulation causing strangury. If the Upper Jiao Qi is not clear and肃 (solemn/clear), failing to distribute, remaining in the chest, the essence of water all becomes turbid. Yang excess frying and burning creates phlegm; Yin excess condensing and storing creates fluid retention. Therefore, treating phlegm focuses on clearing fire: excess patterns use draining methods, deficiency patterns using resolving methods. Treating fluid retention focuses on drying dampness: excess patterns using purging methods, deficiency patterns using warming methods. Thus, ancients had warming and tonifying methods for treating fluid retention, but none for treating phlegm. Wang Yinjun created Mengshi Guntan Wan as a formula for old phlegm, using Huangqin to clear formless heat in the chest, Dahuang to purge solid fire in the intestines and stomach. This shows that treating phlegm requires clearing fire. Using the dry and fierce nature of Mengshi shows that treating phlegm requires removing dampness. Using the rapid descending nature of Chenxiang shows that treating phlegm requires promoting Qi movement. With Mengshi and Chenxiang, Huangqin and Dahuang can swiftly sweep and attack the nests of old phlegm, leaving no turbid and greasy filth behind, which is why it is named "Rolling Phlegm." If Yang Qi is not abundant and phlegm-fluid retention occurs together, this formula is not suitable; instead, combine with Zhimi Fuling Wan. Use Banxia to dry dampness, Fuling to渗 (percolate/drain) dampness, Fenghuaxiao to soften hardness, and Zhike to promote Qi movement. Different from the sweet and緩 (slow/gentle) nature of Erchen Tang, and far from the drastic nature of Dahuang and Mengshi, this is likely a moderate formula among purgatives!

Jingui Zhizhu Tang (Golden Cabinet Aurantium and Atractylodes Decoction) treats hardness below the heart like a large plate, rotating at the edges like a cup, caused by fluid retention.
Zhishi (Aurantii Fructus Immaturus, 7 pieces), Baizhu (Atractylodis Macrocephalae Rhizoma, 2 liang).
Take the above two herbs, add five sheng of water, boil to obtain three sheng, divide into three warm doses. The abdomen softens and the condition resolves.
[Note] "Below the heart" refers to the upper part of the Stomach (Shangwan). Hardness in Shangwan like a plate, rotating at the edges like a cup, indicates fluctuating size due to water qi, not solid food stagnation. Use Zhishi to break stagnant Qi, Baizhu to remove water-dampness. Taking three warm doses will soften the abdomen, open knots, and resolve hardness. Li Gao followed Zhang Zhongjing's method by doubling Baizhu in this formula, making it primarily tonifying; this formula uses Zhishi as the sovereign herb, making it primarily purgative. However, one is slow and one is rapid, one tonifies and one purges, their uses differ only in the balance of quantities.

Guiling Gan Zhu Tang (Cinnamon Twig, Poria, Licorice, and Atractylodes Decoction) treats phlegm-fluid retention in the chest with fullness and distension in the hypochondrium and dizziness. It also states: "Shortness of breath with slight fluid retention should be eliminated via urination; Guiling Gan Zhu Tang governs; Shenqi Wan also governs."
Fuling (Poria, 4 liang), Guizhi (Cinnamomi Ramulus, 3 liang), Baizhu (Atractylodis Macrocephalae Rhizoma, 3 liang), Gancao (Glycyrrhizae Radix et Rhizoma, 3 liang).
Take the above four herbs, add six sheng of water, boil to obtain three sheng, divide into three warm doses. Urination will become smooth.
[Collected Notes] Zhao Liang said: The Ling Shu states that pulsation of the Pericardium Meridian causes chest and hypochondriac fullness and distension, indicating phlegm-fluid retention accumulating in the Pericardium. Dizziness occurs because phlegm-fluid retention obstructs Yang Qi in the chest, preventing it from distributing essence upward. Fuling is light and percolating, allowing fluid retention to exit via the lower orifices through urination, hence used as the sovereign herb. Guizhi unblocks Yang, transports water to the skin and hair, resolving via sweating, hence used as the minister herb. Baizhu dries dampness, assisting Fuling to eliminate phlegm and relieve fullness. Gancao tonifies the Middle, assisting Guizhi to establish Earth to control Water evil. Shortness of breath with slight fluid retention is caused by water-fluid retention hindering respiration. The Jingui Yaolue presents both formulas, highlighting their profound meaning. Shortness of breath upon exhalation is treated with the light and clear Guiling Gan Zhu Tang to unblock Yang; when Yang transforms Qi, urine can be discharged. Shortness of breath upon inhalation is treated with the heavy and descending Shenqi Wan to unblock Yin; when Kidney Qi flows, the gate opens naturally.
[Commentary] Fengshui (Wind Edema) is Yang Water; Shishui (Stone Edema) is Yin Water. Yang Water is mostly excess, Yin Water is mostly deficiency. Yang Water is located superiorly, thus often causing panting; Yin Water is located inferiorly, thus often causing fullness. Therefore, treating Yang Water uses dispersing and purging methods, while treating Yin Water uses warming and tonifying methods. However, within Yin there must be Yang. This formula treats Yin Water located in the Yang position and superiorly; Shenqi Wan treats Yin Water located in the Yin position and inferiorly. Inferring from this, within Yang there must also be Yin, hence the treatment methods of Xiao Qinglong Tang and Wuling San. Nowadays, people fail to distinguish between Yin/Yang and excess/deficiency, treating everyone with Jingui Shenqi Tang. When ineffective, they persist without changing course, often leading to hematemesis and death, which is truly lamentable.

Shuozao Yinzi (Draining and Scouring Decoction) treats generalized edema, panting, thirst, and constipation of both bowels.
Qianghuo (Notopterygii Rhizoma et Radix), Qinjiao (Gentianae Macrophyllae Radix), Binglang (Arecae Semen), Dafupi (Tangerinae Pericarpium Rubrum), Shanglu (Phytolaccae Radix), Fulingpi (Poria Peel), Jiaomu (Zanthoxyli Semen), Mutong (Akebiae Caulis), Zexie (Alismatis Rhizoma), Chixiaodou (Phaseoli Semen Rubrum) (equal parts).
Add Jiangpi (Zingiberis Pericarpium), decoct in water and take.
[Note] The Classic says: "The Sanjiao is the official of irrigation, where water passages emerge." If water retention blocks internally and wind-cold binds externally, the Qi transformation of the Sanjiao fails. The Upper Jiao like mist, the Middle Jiao like fermentation, all become like the Lower Jiao like a ditch. This leads to water qi flooding externally causing skin edema, retaining internally causing abdominal distension, attacking upward causing panting, coughing, and vomiting, accumulating downward causing difficult urination, and various other symptoms. The treatment method ultimately revolves around the Exterior and Interior. Xiao Qinglong Tang, Zhenwu Tang, Yebibo Tang, Wuling San, and Shuozao Yinzi are all formulas treating water qi with combined Exterior and Interior syndromes. Xiao Qinglong Tang treats Exterior-Interior Cold-Excess with water qi inside. Zhenwu Tang treats Interior Deficiency-Cold with water qi inside. Both syndromes do not present with internal distension or external edema. Thus, one uses Mahuang and Guizhi to disperse cold and move water; the other uses Jiang and Fuzi to warm cold and control water. Yebibo Tang treats Exterior-Interior Heat-Excess with water qi inside. Wuling San treats Exterior-Interior Heat-Deficiency with water qi inside. Thus, one uses Mahuang and Shigao to disperse water in the skin and clear heat in the muscles to reduce swelling; the other uses Guizhi, Fuling, Baizhu, and Zexie to resolve muscle-surface heat and promote diuresis of retained water to stop vomiting. Shuozao Yinzi treats combined Exterior-Interior Excess, neither leaning towards Cold nor Heat, but with excessive water-dampness, causing generalized edema, panting, distension, and constipation. Thus, Shanglu is used as the sovereign herb to specifically move all waters. Assisted by Qianghuo, Qinjiao, Dafupi, Fulingpi, and Jiangpi to move water in the Exterior, dispersing through the skin; assisted by Binglang, Chixiaodou, Jiaomu, Zexie, and Mutong to move water in the Interior, exiting via the two bowels. Distributing and eliminating the pathogenic factor from top/bottom and inside/outside, similar to the intent of Yu the Great dredging rivers. Regarding Yebibo Tang adding Banxia, it is for rebellious Qi causing panting, using it to direct rebellion downward; adding Fuzi is for sweating and aversion to wind, using it to disperse the Exterior and secure Yang. Adding Shigao to Xiao Qinglong Tang is for panting with restlessness, using it to clear Stomach heat concurrently. Replacing Baizhu and Guizhi with Huashi and Ejiao in Wuling San creates Zhuling Tang, specifically clearing Yin and treating water. Removing Jiang and adding Renshen to Zhenwu Tang creates Fuzi Tang, specifically warming Yang and not treating water. From this, we see Zhang Zhongjing's prescription skills: adding major cold herbs to groups of warm herbs; adding acrid-hot herbs to major cold herbs. Removing Guizhi and adding Huashi prevents exterior dispersion; removing Jiang and adding Renshen shifts focus from treating water. Such transformative changes are divine; rigid scholars cannot discuss this.

Tingli Dazao Xiefei Tang (Descurainia Seed and Jujube Decoction to Drain the Lung) treats lung abscess with panting unable to lie down, and acute panting due to water-fluid attacking the Lung.
Tingli (Descurainiae Semen seu Lepidii Semen, bitter, 1 liang), Dazao (Zizyphi Fructus, 10 pieces).
Use five zhong of water, first boil dates until three zhong remain, remove dates, add Tingli, boil to obtain one and a half zhong, take in one dose. Reduce dose for weak patients. Avoid salt and soy sauce.

Suting Dingchuan Wan (Perilla Seed and Descurainia Seed Calming Panting Pill) treats fluid retention in the Upper Jiao attacking the Lung causing panting, fullness, inability to lie down, facial and body edema, and difficult urination.
Kutinglizi (Descurainiae Semen, ground into paste), Nanzisu (Perillae Fructus, ground into paste).
Equal parts, mix evenly, use date pulp to make small pills, dry in shade, store in porcelain jars to prevent loss of oiliness which reduces efficacy. Take 3 qian each time, at midnight (third watch) with warm water. Aim for 4-5 bowel movements; reduce dose if too many, increase if too few. If the body feels soft the next day, take every other day or every two days. For weak constitution, start with half dose, gradually increase as tolerated. Avoid salt and soy sauce. Immediate miraculous effects are expected. If strict avoidance of salty foods is not observed, even correct prescriptions may fail.

Zhouche Shenwan (Boat Cart Divine Pill, also known as Jingfu Wan) treats edema and water distension with robust constitution and strong Qi.
Heiqianniu (Pharbitidis Semen, fried, 4 liang), Dahuang (Rhei Radix et Rhizoma, wine-soaked, 2 liang), Gansui (Kansui Radix, wrapped in flour and roasted, 1 liang), Daji (Euphorbiae Pekinensis Radix, wrapped in flour and roasted, 1 liang), Yuanhua (Genkwa Flos, vinegar-fried, 1 liang), Qingpi (Citri Reticulatae Pericarpium Viride, fried, 1 liang), Juhong (Citri Reticulatae Pericarpium, 1 liang), Muxiang (Aucklandiae Radix, 5 qian), Binglang (Arecae Semen, 5 qian), Qingfen (Calomelas, 1 qian).
Grind into powder, make pills with water. Take 5 fen each time, at dawn (fifth watch) with boiling water. Stop when bowel movements occur three times. If no relief after one or two times, continue the next day. Gradually increase from 6-7 fen to 1 qian. If bowel movements occur 4-5 times or constitution weakens, reduce dose to 2-3 fen, or take every 1-3 days until cured. Severe cases should avoid salt and soy sauce for 100 days.
[Note] Tingli Dazao Tang, Suting Dingchuan Wan, and Zhouche Shenwan are all formulas for treating swelling. Tingli Dazao Tang treats water retention in the chest, lung fullness, panting, inability to lie down, skin edema, and mild central fullness. It uses the bitterness of Tingli alone to first drain water qi from the Lung, assisted by Dazao to prevent bitterness from damaging the Stomach. Suting Dingchuan Wan adds Nanzisu to the previous formula to direct Qi downward; when Qi descends, water descends. Directing Qi downward regulates the source of water transmission, allowing water to flow downstream. Zhouche Shenwan treats water retention in various interior locations, attacking upward causing panting and difficulty lying down, accumulating downward causing difficult urination, pressing externally causing edema, and stopping centrally causing urgent distension. It employs Gansui, Daji, Yuanhua, Qian Niu, and Dahuang to directly attack the nests of water, expelling it via the two bowels. Assisted by Qingpi, Chenpi, and Muxiang to move Qi; when Qi moves, water moves, resolving both swelling and distension. Its particularly drastic aspect lies in adding Qingfen, making the water-moving and Qi-moving herbs swift and irresistible, penetrating everywhere, reaching infinitely. Used correctly, its efficacy is magical, hitting the mark every time. However, it should not be lightly tried unless the constitution is robust or pathogenic factors are strong. Greed for its ability to forcibly eliminate disease may lead to recurring swelling after reduction; users must be cautious!

Shipi Yin (Solidify the Spleen Decoction) treats heaviness of the body, poor appetite, limb edema, lack of thirst in the mouth, and loose stools and urine.
Baizhu (Soil-fried), Fuling, Gancao (Roasted), Houpo (Ginger-fried), Fuzi (Prepared), Ganjiang (Dried Ginger), Caoguo Ren (Tsao-ko Seed), Muxiang, Mugua, Dafuzi (Areca Catechu Seed).
Decoct with Ginger and Jujube. Add Renshen for Qi deficiency.
[Note] Spleen-Stomach deficiency means Earth cannot control Water, so Water wanders onto the muscle surface, causing heaviness and edema. Baizhu, Gancao, Shengjiang, and Dazao are used to solidify Spleen-Stomach deficiency. Spleen-Stomach cold means Middle-Jiao cold cannot transform water, so water retains in the intestines and stomach, causing poor appetite, lack of thirst, and loose stools/urine. Jiang, Fuzi, and Caoguo are used to warm Spleen-Stomach cold. Assisted by Dafu, Fuling, Houpo, Muxiang, and Mugua to guide water and move Qi. Qi is the mother of Water; Earth is the defense against Water. When Qi moves, Water moves; when Earth is solid, Water is controlled. Hence named "Solidify the Spleen." However, this formula has sufficient power to guide water and move Qi. It is suitable for Yin Water with Cold excess and no Qi deficiency. If Qi is scant and voice is faint, Lizhong Tang plus Fuzi, with multiple times the amount of Fuling as the sovereign herb, should be used to warm and tonify Yuan Qi to move water, which is the ultimate solution.
[Commentary] Linggui Zhugan Tang, Shipi Yin, and Shenqi Wan all treat syndromes of Yang deficiency with water qi. Linggui Zhugan Tang treats Upper Jiao Yang deficiency failing to distribute, water staying superiorly, causing reverse fullness below the heart and Qi rushing to the chest. Thus, Ling, Gui, Zhu, and Gan are used to support Yang, unblock Qi, and regulate water passages. Shipi Yin treats Middle Jiao Yang deficiency failing to steam and transform, water soaking in the Middle, flooding externally causing edema, with free urination and defecation. Thus, Jiang, Fuzi, Ling, and Zhu are used to cultivate Earth, warm the Middle, and overcome cold-dampness. Shenqi Wan treats Lower Jiao Yang deficiency failing to move water, causing difficult urination, limb edema, panting, and abdominal distension. Thus, Gui, Fuzi, Di, and Ling are used to warm and tonify to move water.

Qingpi Yin (Clear the Spleen Decoction) treats malaria formed by phlegm accumulation, without Exterior or Interior syndromes.
Qingpi, Houpo, Caoguo, Banxia, Chaihu, Baizhu, Gancao, Fuling, Huangqin.
Decoct in water and take.
[Note] Malaria involving Shaoyang with Taiyang Exterior is treated with Ma Gui Ge Ban Tang (half dose of Ma Huang Tang and Gui Zhi Tang) to induce sweating; involving Yangming Interior is treated with Da Chaihu Tang to purge. If not involving Exterior/Interior, or recurring after sweating/purging, treat via Shaoyang harmonizing method. This formula combines Xiao Chaihu Tang and Si Jun Zi Tang to clear Shaoyang while attending to the Spleen, hence named "Clear the Spleen." Ginseng is reduced because Qi is not deficient; Caoguo and Houpo with strong aromas are added to transport Stomach accumulation. Qingpi, assisted by Fuling and Banxia, is used to break the origin of phlegm. Ancients said: "No phlegm, no malaria; no accumulation, no malaria." This formula exemplifies this. For Qi deficiency, add Ginseng; for Qi excess, add Binglang; for more heat, add Shigao; for more sweating, add Guizhi. Adjustments should be made based on the specific case.

Shaoyao Tang (Peony Decoction) treats dysentery with red and white discharge, pus and blood in stool, tenesmus, and painful urgency.
Shaoyao (Paeoniae Radix Alba, 2 liang), Danggui (Angelicae Sinensis Radix, 5 qian), Huanglian (Coptidis Rhizoma, 5 qian), Huangqin (Scutellariae Radix, 5 qian), Binglang (Arecae Semen, 3 qian), Muxiang (Aucklandiae Radix, 3 qian), Gancao (Glycyrrhizae Radix et Rhizoma, 3 qian).
Take 0.5 liang each time, decoct in water. If dysentery does not cease, add Dahuang.
[Note] Dysentery arises in summer and autumn, caused either by external damp-heat or internal raw/cold food, fermenting and郁 (stagnating) into heat. Initially affecting Fu organs, later transmitting to Zang organs. Fu organ diseases are easy to treat; Zang organ diseases are difficult. What are Fu organs? Disease in the Large Intestine transforms according to Metal, hence white color; disease in the Small Intestine transforms according to Fire, hence red color. Red dysentery often involves "Jinkou" (lockjaw/inability to eat) because the Small Intestine is close to the Stomach, allowing foul qi to attack upward, causing vomiting and anorexia. What are Zang organs? Transmission to the Heart causes unremitting heat and bloody diarrhea; transmission to the Kidney causes incessant diarrhea like a leaking roof; transmission to the Spleen causes inability to ingest liquids and hiccups/anorexia. This formula treats early-stage Fu organ disease. Danggui and Baishao regulate Blood; Muxiang and Binglang regulate Qi. Harmonized Blood removes pus and blood; regulated Qi stops tenesmus. Huangqin and Huanglian dry dampness and clear heat; Gancao harmonizes the Middle and the herbs. If pain and urgency are severe, or dysentery persists after taking the medicine, add Dahuang to use "treat obstruction with unblocking" (tonification of excess via purgation).

Wenpi Tang (Warm the Spleen Decoction) mainly treats entrenched cold in the intestines and stomach causing diarrhea and abdominal pain. It should be removed first, then regulated. One should not assume deficiency and merely nourish the disease.
Houpo (Magnoliae Officinalis Cortex, 2 liang), Ganjiang (Zingiberis Rhizoma, 2 liang), Gancao (Glycyrrhizae Radix et Rhizoma, 2 liang), Guixin (Cinnamomi Cortex, 2 liang), Fuzi (Aconiti Lateralis Radix Praeparata, 2 liang), Dahuang (Rhei Radix et Rhizoma, 4 qian).
Chop the above, take 1 liang, add two zhong of water, decoct to six tenths, take in one dose.
[Collected Notes] Yu Chang said: Xu Shumi created this formula, deeply aligning with Zhang Zhongjing's method of purging with warm herbs. Using only 4 qian of Dahuang shows great insight. If entrenched cold in the intestines and stomach causes diarrhea, how dare one use the fierce strength of Dahuang in warm herbs to further distress? Reducing it by one-fifth reveals Xu Shumi's deep understanding of Zhang Zhongjing. Zhang Zhongjing said: "Patients with chronic loose stools should not take Zizhi Tang." He also said: "Taiyin disease, weak pulse, free passage; if Dahuang or Shaoyao should be used, reduce the dose, because the person's Stomach Qi is weak and easily disturbed." From this, can one recklessly use Dahuang for diarrhea caused by intestinal cold? Not using it, warm herbs may fail to control it, and the tendency toward profuse diarrhea may worsen. Careful consideration and use are truly worthy of emulation.

Dahuang Fuzi Tang (Rhubarb and Prepared Aconite Decoction) treats unilateral pain under the ribs with fever, tight and string-like pulse, indicating cold, to be treated with warm purgatives.
Dahuang (Rhei Radix et Rhizoma, 2 liang), Fuzi (Aconiti Lateralis Radix Praeparata, 2 pieces, prepared), Xixin (Asari Radix et Rhizoma, 2 liang).
The above three herbs, add five sheng of water, boil to obtain two sheng, divide into three warm doses. For strong individuals, take two and a half sheng, divided into three doses. After taking, wait the time it takes for a person to walk four or five li, then administer again.
[Collected Notes] Yu Chang said: Zhang Zhongjing treated Shaoyang heat pathogen stagnating in the chest with Yang deficiency and Yin excess using the method of Fuzi Xie Xin Tang. In miscellaneous diseases, unilateral rib pain and fever are Yang, while tight/string-like pulse is Yin; thus, Yin pathogen counterattacking within Yang is known. He established this method of purging with warm herbs. However, Zhang Zhongjing earnestly transmitted his core teachings, yet few in later generations grasped them. The Jingui Yaolue adds another clause: "If the pulse is rapid and tight, resembling a bowstring, unyielding to pressure, rapid and string-like pulse indicates cold should be purged; tight and slow pulse indicates hardness in the epigastrium; large and tight pulse indicates Yin within Yang, purging is possible." Readers fail to understand this purging with warm herbs method. "Purge the cold" means Yin-excess pathogens within Yang can be purged; is not the golden needle jumping forth?
Zhang Lu said: San Chengqi Tang are gentle purgatives for cold; Baisan and Beiji Wan are harsh purgatives for heat; Fuzi Xie Xin Tang and Dahuang Fuzi Tang are harmonizing agents for cold-heat binding, combining harsh and gentle. Modern practitioners only know cold purging, completely unaware of warm purging. Because sudden...
