[Commentary by You Zaijing] The "Shu" pulse (rapid pulse) indicates sores and heat syndromes. Currently, the patient has no fever on the exterior, but there is heat from sores within. If the heat resides in the Yin aspect, it manifests as silence and a desire to sleep; if the heat resides in the Yang aspect, it manifests as slight irritability and sweating. However, when this disease first begins, after three or four days, if the eyes become red like those of a turtledove, this indicates heat accumulating in the blood vessels, causing the collaterals to turn red. After seven or eight days, if the area around the eyes turns black, this indicates heat stagnating in the blood and rotting flesh, causing the collaterals to turn black. If the patient cannot eat, the toxin remains latent in the interior; if the patient can already eat, the toxin has transformed into pus.
[Commentary by Cheng Zhi] Those who can eat indicate that the pathogenic factor is diffuse, not residing in the Zang-Fu organs, but in the Yin region of the anus, where flesh rots and muscles decay, forming pus.
[Commentary by You Zaijing] Note: Regarding this passage, some commentators classify it as Hu-Huo Disease (Fox-Sorcery Disease), while others classify it as Yin-Yang Toxicity. In essence, it is also a disease caused by damp-heat accumulating into toxicity. If it does not rot into worms, it accumulates into an abscess. If it does not appear on the body or face, it appears in the intestines and viscera. This is also the natural trend of pathological mechanisms. Zhang Zhongjing's intent seems to be that this disease shares the same origin but different manifestations with Hu-Huo Disease and Yin-Yang Toxicity, hence it is specifically discussed here.
Chixiaodou Danggui San Formula
Chixiaodou (Red Bean Seed) [3 Sheng, soaked until sprouted, then dried] Danggui [Angelicae Radix Sinensis] (10 Liang ○ Note: The original text lacks the weight; supplemented here according to the Song edition and Yu's edition. Qianjin Fang uses 3 Liang; Xu Rong's *Fuyi* cites Pang Anshi using 1 Liang.)
The above two ingredients are pounded into a powder. Take one Fangcun Bi (a square-inch measure) with Jiangshui (fermented grain water), three times daily.
[Commentary by Cheng Zhi] Danggui treats malignant sores and ulcers; Chixiaodou expels abscess swelling; Jiangshui regulates the Zang-Fu organs. These ingredients constitute a formula for treating formed pus. This formula should be used for lesions eroding the anus. According to the later text describing bleeding before stool, this is "Jin Xue" (proximal blood), which also uses this decoction. Since the large intestine and anus share the same source, although the diseases differ, the principle of resolving visceral toxicity remains the same. (Jiangshui refers to acidic water made by cooking millet rice hot, throwing it into cold water, soaking for five to six days until white flowers grow, resembling the color of gruel. Note: The method for making Jiangshui comes from *Bencao Mengqian*.) Zhang Shi's *Yitong* states this formula treats intestinal abscesses, groin swellings, and various evils of lower body blood stasis.
Yang Du (Yang Toxicity) presents with a red face with patterns like brocade, sore throat, and spitting of pus and blood. It is treatable within five days; after seven days, it is untreatable. It is primarily treated with Shengma Biejia Tang (Cinnamon Twig and Turtle Shell Decoction). (*Mai Jing* omits the characters "Biejia".)
Yin Du (Yin Toxicity) presents with a blue-green complexion, body pain as if beaten with a club, and sore throat. It is treatable within five days; after seven days, it is untreatable. It is primarily treated with Shengma Biejia Tang, removing Xionghuang (Realgar) and Shujiao (Sichuan Pepper). (*Zhou Hou Bei Ji Fang* writes "passing this leads to death" instead of "seven days untreatable"; *Mai Jing* and *Qianjin Fang* write "Gancao Tang" instead of the ten characters starting from "Shengma".)
[Commentary by You Zaijing] "Toxicity" refers to pathogenic factors accumulating and failing to resolve. Yang Du is not necessarily extreme heat, nor is Yin Du necessarily extreme cold. Pathogens in the Yang aspect are called Yang Du; pathogens in the Yin aspect are called Yin Du. The Yin and Yang mentioned here do not refer to Zang-Fu or Qi-Blood, but rather: symptoms such as a red face with brocade-like patterns, sore throat, and spitting pus/blood, where the pathogen attaches to the exterior, are called Yang; symptoms such as a blue-green complexion, body pain like being beaten, sore throat, and no spitting of pus/blood, where the pathogen is hidden in the interior relative to the exterior, are called Yin. Therefore, both can use acrid-warm ascending-dispersing herbs to vent the accumulated pathogens, and simultaneously use sweet-moist salty-cold flavors to pacify the Yin disturbed by pathogens. Within five days, the pathogen is shallow, making dispersion easier, hence treatable. After seven days, the pathogen is deep, making dispersion difficult, hence untreatable. Shujiao and Xionghuang are used in Yang Du to assist Yang with Yang, aiming for rapid dispersion. They are removed in Yin Du to avoid forcibly attacking Yin pathogens and damaging Yin Qi.
[Commentary by Shen Jin'ao] Yin Du is not Yin-Cold, but rather Yin Blood congealing due to cold, thus forming Yin Du. Later generations misunderstood its meaning, viewing it as direct invasion of Yin-Cold transforming into Yin Du, and proposed formulas like Pilei San and Zhengyang Dan. (Note: Commentaries by Xu Lingtai and Cheng Zhi hold similar views.) These individuals have not entered the gate of Zhang Zhongjing's scholarship. Only Wang Andao of the Yuan Dynasty correctly辨析 (analyzed) that it is not direct Yin-Cold invasion (*Suhui Ji*). His words were straightforward and principles correct, though he mistakenly claimed that heaven and earth's evil toxic qi were confused, leaving later generations at a loss. (Note: *Jin Jian* based on Wang's statement claims Yin/Yang Du are what modern people call Sha Syndrome. Removing Realgar and Sichuan Pepper for Yin Du must be a transcription error. Thus, treatment should ignore Yin/Yang distinctions, focusing on bleeding from acupoints Chize, Weizhong, and finger veins. Mild cases use scraping therapy followed by Zijin Ding. This view is unacceptable.)
Shengma Biejia Tang Formula
Shengma (Cimicifugae Rhizoma) (2 Liang) Danggui (Angelicae Radix Sinensis) (1 Liang) Shujiao (Sichuan Pepper, stir-fried to remove sweat, 1 Liang) Gancao (Licorice Root) (2 Liang) Biejia (Trionycis Carapax) (one piece the size of a finger, roasted) Xionghuang (Realgar) (0.5 Liang, ground)
The above six ingredients are boiled in 4 Sheng of water to obtain 1 Sheng. Take all at once. Elderly and children take another dose to induce sweating.
[Original Note] *Zhou Hou Bei Ji Fang* and *Qianjin Fang*: Yang Du uses Shengma Tang without Biejia but with Guizhi; Yin Du uses Gancao Tang without Xionghuang. ○ Note: 4 Sheng in *Zhou Hou* is 5 Sheng; 1 Sheng in *Yu Han* is 2 Sheng, which seems more plausible.
*Lantai Gui Fan* notes: Shujiao is acrid-hot; used in Yang Du but removed in Yin Du, suggesting an error. *Huo Ren Shu* adds Xijiao (Rhinoceros Horn - now substituted with Buffalo Horn) and four other ingredients, which is quite appropriate.
Dong Shi's *Yiji* states: This decoction treats both Yang and Yin Du. Yang Du uses this formula; Yin Du uses this formula minus Xionghuang and doubled Chuanjiao (Sichuan Pepper). Since Yin Du does not spit pus/blood, Xionghuang is removed; since Yin excess leads to Yang deficiency, Chuanjiao is doubled. Generally, years of excessive Yang feature more Yang Du; years of flowing abundance feature more Yin Du. However, whenever encountering these conditions, applying standard treatments yields no success. Most regard them as incurable. Yuan Yunlong, a centenarian, stated: Carefully examining these two conditions, both feature "sore throat." In surgical texts, Lock-Throat Wind, Entangling-Throat Wind, and Iron Moth Entanglement present similarly: red faces like spots, grimacing blue-black faces, spitting pus/blood, body pain like beatings, shortness of breath, delirium, and irritability. The suffering centers on throat obstruction. Once developed, if not improving within 3-5 days, there is no hope. Are these not akin to Yang/Yin Du? Examining pulses: slow and large indicates survival; fine and rapid indicates death. I treated these two conditions using phlegm-resolving formulas for throat diseases, saving many lives.
Note: Chao Yuanfang's *Zhubing Yuanhou Lun* states: To distinguish Yin/Yang Du, check fingers/toes upon onset. Cold indicates Yin; warm indicates Yang. Also: Yang Du features red face or bloody/purulent stool; Yin Du features blue face and cold body. Red macules: 1 survives out of 10; Black macules: 9 die out of 10. *Qianjin Fang* also states: Yang Du involves delirium, running, hallucinations, hematemesis, diarrhea, with floating-large-rapid pulses. Yin Du involves shortness of breath, vomiting, cyanotic lips/black face, cold limbs, with sinking-fine-tight-rapid pulses. Thus, Yang Du requires *Huo Ren Shu*'s Yang Du Shengma Tang or Huaban Tang (later known as Yang Ban). Yin Du requires Pang Shi's Fuzi Yin, Pilei San, or Zhengyang Dan (later known as Yin Ban). Using only Shengma Biejia Tang for both is questionable. Dong Shi's claim of zero efficacy seems valid.
