Yangming disease, characterized by anhidrosis (absence of sweating), difficulty in urination, and mental restlessness with inner vexation (Xin Zhong Ao Nao), will inevitably result in jaundice.

When fluids enter the stomach, they are steamed and transformed by Stomach Yang into Qi; when Qi descends, water transforms into Yang Qi, and when Qi ascends, the generated water vapor is excreted outward as sweat; when Qi stores, the Qi-transformed water flows downward to become urine. When sweat is excreted and urination is smooth, damp-heat is vented, thus jaundice does not occur. If there is no sweat and urination is difficult, dampness cannot be excreted, leading to stagnation and heat generation. This heat steams upward, causing mental restlessness and inner vexation, and the body will inevitably develop jaundice.

In Yangming disease, if fire therapy is applied, resulting in only slight sweating on the forehead and difficulty in urination, jaundice will inevitably occur.

Yangming disease with anhidrosis indicates deficient Yang and dampness in the Spleen-Earth. If fire fumigation is used to force sweating, but only slight sweat appears on the forehead while the body remains dry, combined with difficulty in urination, dampness has no outlet for excretion. It stagnates and generates heat, inevitably leading to jaundice.

In Yangming disease, fever accompanied by sweating indicates that heat is venting outward (Re Yue), so jaundice cannot occur. However, if there is sweating only on the head, no sweating on the body, stopping at the neck, along with difficulty in urination and thirst desiring fluids, this indicates stagnant heat trapped inside. Jaundice will inevitably occur, and Yinchen Hao Tang (Artemisia Capillaris Decoction) should be administered (formula see Taiyin Chapter 12).

Sweating allows damp-heat to vent, preventing jaundice. But if only the head sweats while the body does not, damp-heat cannot vent, and if urination is also difficult, jaundice will inevitably occur. In Yinchen Hao Tang, Yin Chen (Herba Artemisiae Scopariae) promotes diuresis and drains dampness, while Zhi Zi (Fructus Gardeniae Jasminoidis) and Da Huang (Radix et Rhizoma Rhei Palmati) relieve vexation and purge heat.

In Yangming disease, a slow pulse, inability to eat to fullness, mild irritability and dizziness after eating, and inevitable difficulty in urination indicate impending Gu Dan (Grain Jaundice). Even if purgatives are used, abdominal fullness remains unchanged because of the slow pulse.

Excess Yin leads to a slow pulse; deficient Yang causes Stomach Qi to rebel, making food unappetizing, hence one cannot eat to fullness. After eating, the Spleen fails to transform, causing middle Jiao stagnation and fullness, with turbid Qi failing to descend, leading to irritability and dizziness. Spleen Earth dampness and Liver Wood stagnation inevitably cause difficult urination. This is impending Grain Jaundice, caused by retained grain Qi stagnating and generating jaundice. Even with purgation, abdominal fullness persists due to Yin excess and the slow pulse.

Yangming Wind Strike presents with a wiry, floating, and large pulse, shortness of breath, abdominal fullness, pain in the hypochondrium and heart region, obstruction of Qi upon prolonged pressing, dry nose, anhidrosis, lethargy, generalized and facial jaundice, difficult urination, tidal fever, occasional hiccups, and swelling around the ears. Acupuncture provides slight relief, but exterior symptoms persist. If more than ten days pass and the pulse continues to float, Xiao Chai Hu Tang (Minor Bupleurum Decoction) should be given (formula see Shaoyang Chapter 2). If the pulse is merely floating without other symptoms, Ma Huang Tang (Ephedra Decoction) should be given (formula see Taiyang Chapter 20). If there is anuria, abdominal fullness, and worsening hiccups, it is incurable.

A wiry, floating, and large pulse in Yangming disease: Wiry belongs to Shaoyang, Floating to Taiyang, Large to Yangming. Thus, it is a combination of all three Yang channels. Shortness of breath and abdominal fullness suggest Taiyin involvement. The Shaoyang channel spreads from the stomach opening to the hypochondrium; Gallbladder and Stomach stagnation cause pain in the hypochondrium and heart; Qi blockage causes obstruction upon pressing. Exterior cold binds the surface, causing Dependent Fire to stagnate and ascend, attacking Lung Metal, leading to a dry nose and anhidrosis (Lung orifices open at the nose). Wood of the Gallbladder attacks Earth of the Stomach, causing gastric fatigue and lethropy. Damp Earth harasses Jia Wood, causing stagnation of both Wood and Earth, leading to generalized and facial jaundice. Dampness and Wood stagnation impair drainage, causing difficult urination. Stomach Qi congestion causes tidal fever. Stomach organ stagnation forces turbid Qi upward, causing hiccups. The Shaoyang channel circulates around the ears; rebellious Qi stagnation causes swelling around the ears. Severe stagnation heat makes acupuncture provide slight relief, but exterior signs remain. After ten days, if the pulse floats continuously from interior to exterior, the pathogen has not entered the Yangming Fu organs or Taiyin Zang organs but remains in the Shaoyang channel. Xiao Chai Hu Tang is appropriate. Chai Hu and Huang Qin clear half-exterior fire; Ren Shen, Gan Cao, and Da Zuo nourish half-interior Yang; Sheng Jiang and Ban Xia descend Stomach Qi and stop hiccups. If the pulse is only floating without wiriness and without Shaoyang symptoms, it is purely a Taiyang disease. Ma Huang Tang is given to vent exterior stagnation. Using Ma Huang for Wind Strike aims to induce sweating to drain Taiyin dampness (Rheumatism cases in Jin Gui Yao Lue use Ma Huang). If there is anuria, abdominal fullness, and worsening hiccups, Water harasses Earth and Earth collapses, rendering it incurable.
