General Principles. In spring and summer, it is appropriate to use diaphoresis (sweating therapy).
This represents Wang Shuhe's deduction of meanings beyond the explicit text. It cites general principles to reveal the main idea. The appropriateness of diaphoresis in spring and summer is to conform to the physiological activity of Yang Qi. However, Shanghan (Cold Damage) is a disease occurring in winter; can one be constrained by this principle?
One should not be constrained by this when considering Zhang Zhongjing's statements.
For all such cases, students of later generations ought to possess distinct insights. If one truly achieves this, then progress in the Dao of medicine will indeed be beneficial.
Regarding any use of diaphoresis, one should aim for uniform sweating throughout the hands and feet, sustained for a period, approximately the time it takes to eat a meal, which is also good. One must not allow sweat to flow profusely like water. If the disease does not resolve, one may re-administer diaphoresis. However, excessive sweating will inevitably lead to Wang Yang (loss of Yang Qi). When Yang Qi is deficient, re-administration of diaphoresis is contraindicated.
This serves as a reiterated caution regarding the degree and measure of diaphoresis.
Whenever decoctions are taken to induce sweating, stop administration once the illness is addressed; there is no need to finish the entire dose.
This serves as a reiterated caution regarding the dosage regimen of administering decoctions.
Wherever it states that diaphoresis is permissible, if no decoction is available, pills or powders may also be used. The essential criterion is that resolution occurs with sweating. Nevertheless, this is inferior to decoctions, which offer better efficacy tailored to specific syndromes.
This demonstrates the appropriate flexibility in using decoctions versus pills/powders. The above five paragraphs are suspected to be the words of Wang Shuhe.
If the patient's pulse is floating and large, and upon inquiry, the patient states only that the stool is hard, assuming purgation would be a major error. Hardness indicates excess; the condition resolves through sweating. Why? Because a floating pulse indicates that the exterior should be resolved via diaphoresis.
This explains that even if the stool is hard, if the pulse presents as floating, one should still resolve the condition via diaphoresis. This likely reflects a concern against premature purgation, thereby conveying a nuanced admonition.
After diarrhea, if the body aches but bowel and bladder functions are normal, urgent treatment of the exterior syndrome is required. Guizhi Tang (Cinnamon Twig Decoction) is appropriate to induce diaphoresis.
This cross-references the end of Article 23 in the Taiyang Chapter, conveying a nuanced admonition.

Excessive sweating leading to Wang Yang (loss of Yang Qi), accompanied by delirium (incoherent speech), is contraindicated for purgation. Administer Chaihu Guizhi Tang (Bupleurum and Cinnamon Twig Decoction) to harmonize Ying and Wei (Nutritive and Defensive Qi), thereby facilitating the flow of Jin Ye (Body Fluids); the condition will subsequently heal spontaneously.
This cross-references the management of mild cases resulting from erroneous sweating causing loss of Yang Qi.
This volume, Chapter 17, contains thirty-one cases, which have been detailed previously.

These four cases are already included within the Taiyang Chapter.
The above two paragraphs reflect Wang Shuhe's classification and chapter arrangement, pointing out those sections of the classic text that cannot be distinctly separated. This encourages readers to meticulously study the intent of the classics and strive for a coherent understanding of their meaning, aiming to exhaust the true essence of the medical Dao. If readers can comprehend this independently, then a comprehensive grasp of the book can be said to be achieved.
