Master Yi stated: The Classic says that those with sweating should not take Mahuang (Ephedrae Herba), and those without sweating should not take Guizhi (Cinnamomi Ramulus). If mistakes are made, the resulting changes are incalculable. Therefore, this method was established to avoid violating the contraindications of the Three Yang channels, making it a divine formula for resolving exterior pathogens, not merely a medicine for miscellaneous diseases.

Respectfully noted: Zhang Zhongjing, in his discussion on releasing-the-exterior medicines for Shanghan, categorized them into the Six Channels, as well as methods for releasing the muscle layer and acupuncture. This was likely out of caution against misusing medicines leading to erroneous transformations. The above collected formulas are all variations of exterior-releasing treatments for Shanghan. One must carefully examine the pulse and symptoms before choosing to use them. However, although Yilao's Jiuwei Qianghuo Tang and Hejian's Tongjie San have different intentions, one must ensure that the medicine corresponds to the syndrome and that the name matches the reality before applying them. Otherwise, violating contraindications will lead to adverse reactions, losing the original intent of establishing the formula. Thus, Xu Wenzheng Gong (Xu Heng) said: In recent times, medical discussions include proponents of Hejian Liu Shi (Liu Wansu) and proponents of Yilao Zhang Shi (Zhang Yuansu). Zhang Shi's medication is based on the rising and falling of Yin and Yang across the four seasons, aligning with the meaning of "Regulating Spirit according to the Four Qi" in the Neijing. A physician who does not understand this and prescribes recklessly lacks skill. Liu Shi's medication focuses on eliminating the old and generating the new, preventing any stagnation, aligning with the meaning of continuous creation in nature. A physician who does not understand this also lacks skill. However, those advocating Zhang Shi may not fully grasp his subtleties, thus fearing to administer medications causing Mingxuan reactions (initial aggravation followed by improvement), leading to missed opportunities and untreatable delays. Those advocating Liu Shi may not fully comprehend his depth, achieving immediate effects but damaging righteous Qi and leaving future harm. If one can utilize the strengths of both schools while avoiding their drawbacks, treatment will likely succeed. From the formulation methods of these two formulas, it is evident that students of medicine should seek understanding in the classics, knowing their respective emphases, and should not be biased toward a single school.
