[Collected Annotations] Cheng Zhi stated: When the dampness and heat in heaven and earth are stagnant and steaming, rain occurs; when the human body feels restless and stifled, sweat is produced. This should be determined by whether the pulse is floating (Fú, superficial). If the pulse is not floating, then the restlessness indicates that the pathogenic factor has entered the interior.
Cheng Yingmao stated: If upon diagnosis the pulse is found to be floating, this is a sign that the pathogenic factor is returning to the exterior. Do not recklessly treat the restlessness, lest what should have been resolved through sweating fails to resolve.
Shen Mingzong stated: Regarding conditions that resolve spontaneously, some resolve through nasal bleeding (Nǜ), some through lower body bleeding, some through diarrhea, and some through the subtle elimination of pathogens via urination. This is but one aspect of the "chills followed by sweating" (Zhàn Hàn) seen in Taiyang disease. One may distinguish it through pulse diagnosis or reference it through symptomatology. The profound principles of Zhang Zhongjing are scattered throughout various chapters; they must be cross-referenced comprehensively to be fully understood.
