In the treatment of heatstroke (Shangshu), it is most crucial to differentiate between Yin and Yang, as well as deficiency and excess. If external pathogenic heat invades and internal restlessness with fever occurs, this indicates heat in both the exterior and interior, constituting a Yang syndrome. The treatment should focus on clearing heat and resolving summerheat.
If the pulse is weak and forceless, or if there is aversion to cold with a cold back, nausea and vomiting, abdominal pain with diarrhea, slight coldness in the four limbs and nasal tip, aversion to drinking cold tea or water, or rapid breathing with shortness of breath and weakness, these are all "Yin within Yang" (indicating true cold/false heat or depletion of Yang Qi). In such cases, one must exclusively protect the Yuan Qi (Original Qi). The primary formula is Sijunzi Tang (Four Gentlemen Decoction), or Lizhong Tang (Regulate the Middle Decoction) modified with Baishao (White Peony Root). If deficiency-cold is severe, treatment must align with the season and specific syndrome, requiring herbs such as Guizhi (Cinnamon Twig), Fuzi (Prepared Aconite Root), and Renshen (Ginseng Root). One must absolutely not use cold-natured herbs to resolve summerheat merely because of the name "summerheat," as doing so would lead to disastrous consequences.
