The general principle is that in spring and summer, diaphoresis (sweating therapy) is appropriate.
When inducing sweating, it is desired that sweat covers the hands and feet uniformly; maintaining this state for a period is better, but one should avoid profuse sweating like flowing water. If the disease does not resolve, diaphoresis may be repeated. However, excessive sweating leads to the loss of Yang Qi (Vital Energy), and when Yang Qi is deficient, further diaphoresis is contraindicated.
When using decoctions to induce sweating, stop administration once the disease is cured; there is no need to finish the entire dose.
If it is stated that diaphoresis is indicated but no decoction is available, pills or powders may also be used, provided that sweating occurs to resolve the pathogen. However, this is not as effective as decoctions, which can be tailored to specific syndromes.
In Taiyang Disease (Disease of the Bladder and Small Intestine channels/Exterior syndrome), if exterior signs persist and the pulse is floating and weak, resolution via diaphoresis is required; Guizhi Tang (Cinnamon Twig Decoction) is suitable.
In Taiyang Disease, if the pulse is floating and rapid, diaphoresis may be applied; this belongs to the indication for Guizhi Tang.
In Yangming Disease (Disease of the Stomach and Large Intestine channels/Interior Heat syndrome), if the pulse is slow, sweating is abundant, and there is slight aversion to cold, the exterior remains unresolved, and diaphoresis may be applied; this belongs to the indication for Guizhi Tang.
If the patient's pulse is floating and large, and upon inquiry, the patient reports only abdominal hardness: if diarrhea is present, it indicates deficiency, which is a severe error. Hardness indicates excess; resolution via diaphoresis is possible. Why? Because a floating pulse indicates the need for diaphoresis. In Shanghan (Cold Damage), if the pulse is neither wiry-tight nor weak, but weak, thirst will necessarily occur. If fire therapy is applied, delirium will ensue. If the weak pulse presents with fever and floating characteristics, resolution via diaphoresis leads to recovery through sweating. If the patient experiences irritability and heat, relief follows sweating. If symptoms resemble malaria with afternoon fever, this belongs to Yangming Disease. If the pulse is floating and deficient, diaphoresis is indicated; this belongs to the indication for Guizhi Tang.
If the patient frequently sweats spontaneously, it indicates that Ying Qi (Nutritive Qi) is harmonious. If Ying Qi is harmonious but the exterior pathogen persists, it is due to disharmony of Wei Qi (Defensive Qi). Ying Qi circulates within the vessels, belonging to Yin, governing the interior; Wei Qi circulates outside the vessels, belonging to Yang, governing the exterior. Re-inducing sweating harmonizes Wei Qi, leading to recovery; this belongs to the indication for Guizhi Tang.
If a patient has no internal organ pathology but experiences intermittent fever and spontaneous sweating without recovery, it is due to disharmony of Wei Qi. Diaphoresis administered prior to the onset of fever leads to recovery; this belongs to the indication for Guizhi Tang.
If the pulse is floating and tight, floating indicates Wind, and tight indicates Cold. Wind injures Wei Qi, and Cold injures Ying Qi. When both Ying and Wei are diseased, causing severe bone and joint pain, diaphoresis may be applied; Mahuang Tang (Ephedra Decoction) is suitable.
If Taiyang Disease is unresolved, heat accumulates in the Bladder, causing mental agitation resembling madness. If blood discharges spontaneously, the disease resolves. If the exterior remains unresolved, attack on the interior is premature; the exterior must first be resolved; this belongs to the indication for Guizhi Tang.
If Taiyang Disease is treated with purgation and results in slight wheezing, it is because the exterior remains unresolved. This belongs to the indication for Guizhi Jia Houpo Xiren Tang (Guizhi Decoction with Magnolia Bark and Apricot Kernel).
In Shanghan, if the pulse is floating and tight, and diaphoresis is not performed, leading to epistaxis (nosebleed), this belongs to the indication for Mahuang Tang.
In Yangming Disease, if the pulse is floating, there is no sweating, and the patient likely suffers from wheezing. Resolution via diaphoresis leads to recovery; this belongs to the indication for Mahuang Tang.
In Taiyin Disease (Disease of the Spleen and Stomach channels/Cold-Damp syndrome), if the pulse is floating, diaphoresis may be applied; this belongs to the indication for Guizhi Tang.
In Taiyang Disease, if the pulse is floating and tight, there is no sweating, fever is present, and body pain persists for eight or nine days without resolution, indicating the exterior pattern continues, diaphoresis is indicated. After taking the decoction, symptoms may slightly improve. Irritability and blurred vision may occur; in severe cases, epistaxis occurs, after which the disease resolves. This is due to heavy accumulation of Yang Qi. This belongs to the indication for Mahuang Tang. If the pulse is floating, the disease is at the exterior, and diaphoresis may be applied; this belongs to the indication for Guizhi Tang.
In Shanghan, if there is constipation for six or seven days accompanied by headache and fever, Chengqi Tang (Gastrointestinal Purging Decoction) might be considered. However, if the stool is clear (or urine is clear), it indicates the disease is not in the interior but at the exterior, so diaphoresis is indicated. Headache may lead to epistaxis; this belongs to the indication for Guizhi Tang.
After dysentery, if body pain persists but bowel and bladder functions are normal, urgent treatment of the exterior is required; Guizhi Tang is suitable.
In Taiyang Disease, if there is headache, fever, sweating, and aversion to wind (or cold), this belongs to the indication for Guizhi Tang.
In Taiyang Wind Strike syndrome, the pulse is floating at the Yang position (cun) and deficient-weak at the Yin position (chi). Floating indicates spontaneous heat; deficient-weak indicates spontaneous sweating. Symptoms include shivering aversion to cold, chilly aversion to wind, mild fever, nasal congestion with humming, and dry retching. This belongs to the indication for Guizhi Tang.
In Taiyang Disease, if there is fever and sweating, it is due to weak Ying Qi and strong Wei Qi, causing sweating. To rescue from pathogenic wind, this belongs to the indication for Guizhi Tang.
In Taiyang Disease, if purgation is mistakenly applied and qi rushes upward, Guizhi Tang may be given; if there is no upward rush, it should not be given.
In Taiyang Disease, if Gui Zhi Tang causes increased irritability without resolution, Fengchi (GB20) and Fengfu (GV16) acupoints should be needled first, followed by Guizhi Tang for recovery.
If burning needle therapy induces sweating, and cold enters the needle site causing red nodules, Ben Tun (Rushing Pig) syndrome may develop. If qi rushes from the lower abdomen to the heart, moxa should be applied to the nodule (one cone), followed by Guizhi Jia Gui Tang (Guizhi Decoction with Added Cinnamon).
In Taiyang Disease, if there is stiffness in the neck and back with sweating and aversion to wind, this belongs to Guizhi Jia Gegen Tang (Guizhi Decoction with Added Kudzu Root).
In Taiyang Disease, if there is stiffness in the neck and back without sweating and with aversion to wind, this belongs to Gegen Tang (Kudzu Root Decoction).
In combined Taiyang and Yangming disease, if there is spontaneous diarrhea without vomiting, this belongs to the indication for Gegen Tang.
In combined Taiyang and Yangming disease, if there is no diarrhea but only vomiting, this belongs to the indication for Gegen Jia Banxia Tang (Gegen Decoction with Added Pinellia).
In Taiyang Disease, if the Guizhi pattern is mistakenly treated with purgation, leading to persistent diarrhea, a rapid pulse indicates the exterior remains unresolved. With wheezing and sweating, this belongs to the indication for Gegen Qinlian Tang (Gegen, Scutellaria, and Coptis Decoction).
In Taiyang Disease, if there is headache, fever, body pain, lower back pain, joint pain, aversion to wind, no sweating, and wheezing, this belongs to the indication for Mahuang Tang.
In combined Taiyang and Yangming disease, if there is wheezing and chest fullness, purgation is contraindicated. This belongs to the indication for Mahuang Tang.
In Taiyang Wind Strike syndrome, if the pulse is floating and tight, with fever, aversion to cold, body pain, no sweating, irritability, and headache, this belongs to Da Qing Long Tang (Great Blue Dragon Decoction). If the pulse is weak and faint, with sweating and aversion to wind, it is contraindicated. Administration would lead to limb coldness and muscle twitching, which is an adverse reaction.
In Shanghan, if the pulse is floating and slow, the body is not painful but heavy, occasionally feeling lighter, and there are no Shaoyin patterns, Da Qing Long Tang is used to induce sweating.
In Shanghan, if the exterior is unresolved and there is fluid retention in the stomach region, causing dry retching, fever, and cough, or thirst, diarrhea, choking, urinary difficulty, lower abdominal fullness, or slight wheezing, this belongs to Xiao Qing Long Tang (Minor Blue Dragon Decoction).
In Shanghan, if there is fluid retention in the stomach region, causing cough and slight wheezing, fever, and no thirst, but thirst develops after taking the decoction, it indicates the cold has dispersed and the disease is resolving. This belongs to the indication for Xiao Qing Long Tang.
In Yangming Wind Strike, if the pulse is wiry, floating, and large, with shortness of breath, abdominal fullness, hypochondriac and cardiac pain, unrelieved pressure, dry nose, inability to sweat, lethargy, jaundice of the body and eyes, difficult urination, tidal fever, frequent hiccups, and swelling around the ears, acupuncture may provide slight relief. If the exterior remains unresolved after ten days and the pulse continues to float, Xiao Chai Hu Tang (Minor Bupleurum Decoction) is given. If only the pulse is floating without other symptoms, Mahuang Tang is given. If there is no urination, abdominal fullness, and hiccups, it is incurable.
In Taiyang Disease, after ten days, if the pulse is floating and fine, and the patient is lethargic, the exterior has resolved. If there is chest fullness and hypochondriac pain, Xiao Chai Hu Tang is given. If the pulse is floating, this belongs to the indication for Mahuang Tang.
In Wind Strike syndrome, with alternating chills and fever, occurring five to six days after Shanghan, with bitter fullness in the chest and hypochondrium, silent desire not to eat, irritability, and frequent vomiting, or chest irritability without vomiting, thirst, abdominal pain, hypochondriac hardness, palpitations, urinary difficulty, absence of thirst, slight exterior heat, or cough, this belongs to the indication for Xiao Chai Hu Tang.
In Shanghan, four to five days in, with body heat, aversion to wind, neck stiffness, hypochondriac fullness, warm hands and feet, and thirst, this belongs to the indication for Xiao Chai Hu Tang.
In Shanghan, six to seven days in, with fever, slight aversion to cold, joint pain, slight vomiting, subcostal support/fullness, and unresolved exterior signs, this belongs to the indication for Chaihu Guizhi Tang (Bupleurum and Cinnamon Twig Decoction).
In Shaoyin Disease (Disease of the Kidney and Heart channels/Deficiency-Cold syndrome), two to three days in, Ma Huang Fu Zi Gan Cao Tang (Ephedra, Aconite, and Licorice Decoction) is used for mild diaphoresis, as there are no significant interior symptoms in two to three days.
If the pulse is floating, there is urinary difficulty, slight fever, and polydipsia, Wu Ling San (Five-Ingredient Powder with Poria) is given to promote urination and induce mild sweating.
