(Chen Wuyue)
Treats *Chanhoufeng* (Entangling Throat Wind), characterized by swelling and pain in the throat and pharynx, with difficulty swallowing; or wind-phlegm obstruction, sores on the mouth and tongue, alcohol toxicity in adults, infantile eczema (*Nai Xuan*), and fish bone impaction.

Xuan Shen (Scrophulariae Radix), Huang Lian (Coptidis Rhizoma), Jing Jie (Schizonepetae Herba), Guan Zhong (Cyathullae Rhizoma), Shan Dou Gen (Sophorae Tonkinensis Radix et Cortex), Fu Ling (Poria), Gan Cao (Glycyrrhizae Radix et Rhizoma), Sha Ren (Amomi Fructus), Hua Shi (Talcum) (each 5 qian), Peng Sha (Borax), Han Shui Shi (Aqua Calcit) (each 3 qian). Grind into fine powder.

Xuan Shen is most effective at nourishing yin and descending fire.
This formula acts on the Foot-Yangming Stomach channel and Foot-Shaoyin Kidney channel. Xuan Shen, Huang Lian, and Han Shui Shi clear heat and purge fire; Guan Zhong and Shan Dou Gen detoxify; Hua Shi and Fu Ling promote urination to leach out dampness; Sha Ren and Peng Sha soften hardness (and can also resolve bone impaction); Jing Jie disperses nodules; Gan Cao harmonizes the middle jiao. Thus, it can comprehensively treat these various conditions. (Zhu Danxi said: For sore throat, Jing Jie must be used; for deficiency fire flaming upward, Xuan Shen must be used. There are cases where yin qi is severely deficient, causing deficiency fire to wander uncontrollably and lodge in the throat, resulting in sore throat. The pulse will be floating and large, but empty upon heavy pressure...)

(*Zhizhi Fang*)
Treats dysentery with red and white discharge, where pus and blood are mixed, accompanied by tenesmus (Strain and urgency). (Damp-heat accumulation invading the blood level results in red discharge; invading the qi level results in white discharge; mixed red and white indicates both qi and blood are affected. Tenesmus is caused by stagnation of qi flow. Note: Tenesmus may be due to fire-heat, qi stagnation, or food retention...)

Huang Lian (Coptidis Rhizoma) (20 liang), Wu Zhu Yu (Evodiae Fructus) (10 liang, stir-fried together), Mu Xiang (Aucklandiae Radix) (4 liang 8 qian, not roasted). Make pills using vinegar paste. Take with rice water.
Another prescription uses equal parts of herbs, made into honeyed pills. Another prescription adds 8 liang of Gan Cao; Huang Lian is moistened with honey-water, steamed and sun-dried nine times, then mixed with Mu Xiang to make pills.
This formula acts on the Hand-Yangming Large Intestine and Foot-Yangming Stomach channels. Dysentery arises from irregular diet and injury by cold or summerheat, leading to steaming and郁 (stagnation) of damp-heat. Huang Lian is bitter and drying to remove dampness, and cold to overcome heat, directly subduing the fire of the Heart and Spleen, hence serving as the Sovereign herb. Wu Zhu Yu is stir-fried with it to utilize its ability to unblock stagnant qi in the Large Intestine (dysentery is a transmission of Spleen disease to the Large Intestine), and to mitigate the excessive cold nature of Huang Lian. Tenesmus is due to qi stagnation; Mu Xiang is acrid and moving to circulate qi, warms and harmonizes the Spleen, unblocks the Triple Burner, drains Lung metal to pacify Liver wood, preventing Wood from overacting on Earth, so that when qi moves, stagnation resolves. One is cold, one is hot; one is yin, one is yang; they have the subtle benefit of mutual assistance, as described in the classics as "treating heat with cold" (Note: Contraindicated in early-stage dysentery because Huang Lian's cloying nature may bind the intestines. *Yuan Bing Shi* states: Some say white dysentery is due to cold; this is wrong. Cold cannot digest grain, how could it transform into pus? Dryness and stagnation causing whiteness belong to Lung Metal. Diarrhea and dysentery always involve dampness. When damp-heat is severe within the intestines and stomach, qi and fluids fail to circulate freely, causing incessant thirst and irritability. The popular notion that red-and-white dysentery implies mixed cold and heat is particularly erroneous. Cold and heat are different pathogens; how can they both become severe in the intestines simultaneously to cause dysentery? Colors appear according to the zones of the Five Zang organs, but the root origin is always heat, differing only in depth. Someone asks: Why do some cases recover after taking acrid-hot medicines? Answer: Because they can open up stagnation, allowing qi and fluids to circulate, moistening dryness, and harmonizing qi. It is better to use acrid-bitter-cold medicines, slightly adding acrid-hot herbs as assistants, such as Qian Yi's Xianglian Wan. Wang Ang notes: Liu Wansu's theory is indeed correct, yet diseases can also present with combined cold and heat pathogens).
Adding Shi Lian Rou (Nelumbinis Semen) to this formula treats Jin Kou Li (Closed-mouth dysentery). Doubling the dosage of Da Huang (Rhei Radix et Rhizoma) treats heat-dysentery with retention. Adding Wu Zhu Yu and Rou Dou Kou (Myristicae Semen) creates Wumei Tang Wan. Adding He Zi (Terminalia Chebulae Fructus) and Long Gu (Fossilia Ossis Mastodi et Ossis Femoris) creates Huanglian Wan (*Xuan Ming Lun Fang*): Both treat persistent dysentery. (Shi Lian clears Heart fire and opens the stomach appetite; Da Huang purges Stomach heat and sweeps away retention; Wu Zhu Yu promotes the flow of stagnant qi; Rou Dou Kou, He Zi, Wumei, and Long Gu all astringe the Large Intestine).
