This is a critical and ominous syndrome. The interior heat of the Yangming channel has reached its extreme. A wiry (Xian) pulse indicates survival, while a choppy (Se) pulse indicates death. This is because a long and wiry pulse suggests that the Stomach Qi remains intact, allowing for the use of Chengqi Tang (Cassia Twig Decoction) to purge, thus offering a chance of life. However, the condition is extremely perilous. Generally, those with a chance of survival may not all recover, whereas those with no Stomach Qi have absolutely no hope of recovery.
Shao's Commentary: If the Stomach Qi is not deficient in this syndrome, it can still be treated, but it remains dangerous. If the Stomach Qi is already deficient, death is inevitable.
If this symptom appears after the application of the sweating, vomiting, or purging methods, it signifies a severe deficiency of Zheng Qi (Upright Qi). There is no need to distinguish between Yin/Yang or Deficiency/Excess syndromes. One should frequently administer Dushen Tang (Single Ginseng Decoction) and Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill) to nourish the body, which often leads to recovery.
The Classics state: "When a patient does not feel aversion to cold but experiences thirst, the pathogen has transferred to the Yangming channel." Therefore, thirst is categorized under the Yangming section. However, thirst can occur in all six channels. (Referenced from *Yi Zong Bi Du*)
Shao's Commentary: Although thirst is predominantly associated with Yangming, it can manifest in all six channels.
Thirst syndromes are mostly caused by damage to Jin Ye (Body Fluids) due to sweating, vomiting, or purging, leading to dryness in the Stomach. When Yang-pathogenic heat attacks the Three Yin channels, it causes dryness of the throat in Taiyin, dry mouth in Shaoyin, and Xiao Ke (Wasting-Thirst) in Jueyin. These also result from heat damaging body fluids. For thirst in Taiyang syndrome, Wuling San (Five-Ingredient Powder with Poria) is used because water retention in the Lower Jiao impedes urination. For thirst in Yangming syndrome, Baihu Tang (White Tiger Decoction) is used because excessive Stomach heat drives constant drinking. For Shaoyang syndrome presenting with irritability and thirst, Xiaochaihu Tang (Minor Bupleurum Decoction) is used for harmonization; Banxia (Pinellia Rhizome) is removed and Huafen (Trichosanthes Root) added to avoid dryness and generate fluids. (Referenced from *Yi Zong Jin Jian*)
For patients desiring water, small amounts should be given to moisten Stomach dryness; once the Stomach harmonizes, the disease resolves. Indiscriminate large-volume drinking will inevitably lead to water retention pathology.
Jiangsu, Fujian, and Zhejiang regions are warm and humid, being areas of damp-heat in the world. The Yangming channel possesses abundant Qi and hot Blood, responsible for receiving and digesting food and water, making it a reservoir for damp-heat in the human body. If one contracts Wind-Warmth or Wind-Heat pathogens, the disease may enter Yangming directly without passing through Taiyang (via inhalation through nose and mouth), or rapidly transfer from Taiyang to Yangming (via skin and hair pores). The internal heat of Yangming combats with external Wind-Heat, condensing into toxicity, often causing macules and papules (Zhen). If the difference between Heat and Cold pathogens is not distinguished, and Taiyang-releasing herbs are indiscriminately used, sweat will not emerge, and rashes will not erupt. Warm-heat burns internally, scorching Stomach fluids, resulting in complicated diseases (Huai Zheng), with many deaths. The following sections detail various Yangming heat syndromes, relying on the clinician's flexibility.
Whenever encountering fever, body pain, thirst, dry lips, or initial mild aversion to cold followed by persistent fever, with a tongue coating yellow in the center and white at the edges, or yellow and dry like thorns, and a surging (Hong) and slippery (Hua) pulse, this indicates Yangming internal heat triggered by new external pathogens. It is suitable to use Xijiao (Rhinoceros Horn - *Note: Substitute with Buffalo Horn in modern practice*), Lianqiao (Forsythia Fruit), Niubangzi (Arctium Fruit), Bohe (Mint), Huangqin (Scutellaria Root), Gegen (Kudzu Root), Fangfeng (Saposhnikovia Root), Mutong (Akebia Stem), etc., to clear and resolve.
If irritability, nausea, cold feet, deafness, a deep (Chen) or floating-restless pulse appear, this indicates the rash is about to erupt. Use the same formula to promote eruption and resolve toxicity. If there is thirst with dry retching, add a handful of Lugen (Reed Rhizome). If the pulse is deep and depressed, do not mistake it for cold; this indicates poor eruption. If the Guan position pulse is hidden (Fu), it indicates heat-toxin stagnation preventing eruption. If the Right Guan pulse is hidden with chest pain, shortness of breath, or cough, it indicates latent Phlegm; treatment should focus on resolving phlegm. Overall, rely on yellow and dry tongue coating as evidence of Excess-Heat, and do not interpret a deep-slow pulse as Deficiency-Cold. Yangming disease is characterized by Stomach excess, leading to constipation. However, when heat pathogens have no exit, they often press downward into the Large Intestine, expelling yellow-black, thick, sticky stool. Hot air must escape from the anus during defecation. This occurs because the pathogen cannot be resolved externally and exits downward. Even if bowel movements occur, treat it as obstruction; do not stop diarrhea. Sometimes, after defecation, sweating occurs leading to resolution. If sweating does not occur, only clear fire, resolve toxicity, and nourish Yin fluids; the pathogen will gradually resolve, and the body will cool. Alternatively, after nourishing Yin, if fluids overflow externally, profuse sweating may occur leading to resolution. If heat-toxin is internally bound, preventing rash eruption, the rash may only appear after defecation. If eruption-promoting methods fail, using only fire-clearing and detoxifying methods may cause the rash to erupt. All these are caused by internally bound heat-toxin. (Determine Yangming internal heat based on yellow-dry tongue coating.)
Shao's Commentary: Shanghan (Cold Damage) and Wenre (Warm Disease) are fundamentally different. In Shanghan, loose stools indicate the pathogen is exhausted; in Warm Disease, loose stools indicate the pathogen is not exhausted. Only when stools become hard is it confirmed that there is no dampness, and only then should purgatives be avoided. Heat-toxin is always judged by yellow-dry tongue coating. If new pathogens trigger internal latent pathogens, where latent pathogens are heavy and new ones light, this is inevitable.
Once the rash has erupted, only clear toxic fire and slightly nourish Yin. Herbs that lift and ascend, such as Chaihu (Bupleurum Root), Gegen (Kudzu Root), and Shengma (Cimicifuga Rhizome), must not be used. Suitable herbs include Lianqiao (Forsythia Fruit), Chishao (Red Peony Root), Xuanshen (Scrophularia Root), Huafen (Trichosanthes Root), Zhimu (Anemarrhena Rhizome), Huangqin (Scutellaria Root), Yinhua (Honeysuckle Flower), Xianshengdi (Fresh Rehmannia Root), Renzhonghuang (Human Midden Yellow), etc. The toxin will naturally transform.
Shao's Commentary: With residual toxins uncleaned, lifting herbs are contraindicated.
If the tongue is crimson red like cinnabar, eyes are red like fire, mouth and lips are dry and cracked, and there is continuous sweating, this indicates Yangming Blood-Heat, with pathogens emerging internally and spreading throughout the Three Jiao. This is Yangming Heat Disease. Wind-dispersing herbs must be strictly avoided. Liangge San (Cool the Upper Jiao Powder) is suitable, removing Mangxiao (Mirabilite) and Dahuang (Rhubarb Root), adding Shigao (Gypsum), Niubangzi (Arctium Fruit), Chishao (Red Peony Root), Xianshengdi (Fresh Rehmannia Root), and Mudanpi (Moutan Cortex). If constipated, remove Mangxiao but keep Dahuang. (This is Yangming Blood-Heat Disease).
Shao's Commentary: Yangming Blood-Heat Disease contraindicates lifting herbs.
If fever, spontaneous sweating, a prickly tongue surface, or yellow-dry thirst, aversion to heat rather than cold are observed, this is Heat in the Qi level of Yangming. Zhizi Chi Tang (Gardenia and Fermented Soybean Decoction) is suitable, adding Lianqiao (Forsythia Fruit), Huangqin (Scutellaria Root), Danzhuye (Lophatherum Leaf), and Lugen (Reed Rhizome) to clear heat. (This is Yangming Qi-Level Heat Disease).
Shao's Commentary: This is the standard treatment for Yangming Qi-Level Heat Disease.
After resolving toxicity or achieving resolution through sweating, if residual heat remains and although stools are closed, the abdomen feels comfortable, only nourish Yin and retreat Yang. Ganlu Yin (Sweet Dew Drink) modified is excellent. Once Yin fluids are restored, residual pathogens recede, and bowels open naturally.
If body heat has subsided but forehead heat persists, this indicates residual pathogens in the Stomach. Clear and disperse Yangming using Lianqiao (Forsythia Fruit), Huangqin (Scutellaria Root), Shengzha (Raw Hawthorn Seed), Maiya (Barley Sprout), Zhike (Aurantii Fructus), and Jinhu (Dendrobium Stem). If the body is cool but abdominal heat persists, this indicates Fire in the Spleen; add Baishao (White Peony Root) to clear it.
