In Taiyang disease, the pulse at the Cun Kou (radial artery) is floating and weak. This indicates deficiency of Blood and Qi, and weakness of Wei Qi (Defensive Qi). A floating pulse implies sweating profusely like beads; due to weak Wei Qi and deficient Ying Qi (Nutritive Qi), the pulse floats and sweating is excessive.

If a patient with Taiyang disease has a floating pulse, but fire therapy is used to force sweating, Yang Qi will be lost, inevitably leading to palpitations, mania, restlessness in lying down and sitting up.

If Taiyang disease is treated with fire steaming and no sweat is produced, the patient will inevitably suffer from dryness and accumulation; if not dry, they will inevitably have bloody diarrhea. If the pulse is restless, jaundice will inevitably develop.

If Taiyang disease is treated with back moxibustion (ironing the back), profuse sweating will occur. Fire Qi enters the Stomach, causing dryness and thirst in the Stomach, inevitably leading to delirious speech.

After Taiyang disease resolves, if the Stomach is dry, causing insomnia and thirst for water, one should give small amounts of water frequently, which will lead to recovery.

If there is vomiting, heat is above the Diaphragm, and the patient desires water, administer Wuling San (Five-Ingredient Powder with Poria). Afterward, water may be drunk.

In Taiyang disease lasting seven or eight days, with severe thirst desiring water, water should be given. However, it should be given such that the patient remains slightly unsatisfied, avoiding overconsumption.

Generally, if a Taiyang disease patient can drink water, it indicates the disease is about to resolve. If the patient is not thirsty but water is forced upon them, disasters resulting from this are numerous.

After inducing sweating, if water is drunk or poured on the body, the patient will inevitably pant. Water and medicine cannot enter the mouth; entering constitutes a counter-indication. In Taiyang Jie Xiong (Chest Binding) without heat signs... [Text fragment missing/obscured in source].

The pulse at Cun Kou is floating and large. The physician erroneously uses purgation, which is a major contraindication. Floating indicates lack of Blood; large indicates Cold. When Cold Qi combats, it causes abdominal borborygmus. The physician, unaware, gives water, causing profuse sweating. Water encountering Cold Qi creates a cold combat, and the illness will surely worsen.

General principle: In winter, warm/hot herbs are suitable.

For diseases presenting with fever, headache, floating and rapid pulse, and body pain, warming the exterior is appropriate.

In Taiyang disease with diarrhea but no thirst, there is Cold in the Zang organs, and warming is appropriate. If the patient desires food but vomits after eating, has cold hands and feet, and a wiry, slow pulse, this is Middle Cold. Vomiting and purging methods are contraindicated. Warming is appropriate.

In Shaoyin disease, if the pulse is deep, urgent warming is required. For diarrhea with anorexia, warming is appropriate. For diarrhea with a slow, tight pulse, pain persists; for diarrhea with a floating, large pulse, this indicates deficiency, and warming is appropriate.

For those with a floating,革 (leather-like) pulse and abdominal borborygmus, if water is given when thirsty, hiccups (Yue) will inevitably occur. Warming is appropriate.

After a major illness and purgation, if diarrhea continues, with undigested food and water passing through, and body pain, urgent rescue of the Interior is needed. Warming is appropriate. Administer Zhongzhi Tang (Regulate the Middle Decoction), Sini Tang (Frigid Extremities Decoction), Fuzi Tang (Aconite Decoction), and other warming formulas.
