四百八种疾病中，大抵热证居多，寒证最少。这就不难理解为什么刘河间主张论火，朱丹溪主张补阴了。但是，拘泥于这两位医家的著作而不考究《黄帝内经》，陷入偏颇，危害人非常严重。因为热病属于阳证，阳邪容易发散、容易治疗，不会致死。冷病属于阴证，阴邪容易潜伏，所以让人不觉得有症状，时间久了就变成虚寒，侵蚀脏腑而死亡。
（初起时没有明显感觉的病证，最能害人，往往被轻视，从而一变证导致死亡的不少。）
况且人体内的火多也是理所当然的，天的六气中，火占其二。现在的庸医执着于“壮火食气”的说法（《黄帝内经》中“壮火食气”的说法，就像盛夏酷暑人气衰弱，相火炽盛则真元受损，并不是指用凉药治疗，也不是指热药，马元台没有洞察这个道理，胡乱进行注释，给后学留下了很多错误。）沉溺于滋阴苦寒的药物，却不知道邪气侵入人体，如果元气旺盛就能抵挡它，现在却用凉药像冰一样使身体冷却，反而泄耗元气，这是帮助贼寇伤害主人啊。凉药不知道害死了多少人。如果元气稍微虚弱的人，没有被凉药冻败而死的，脾胃受到损伤，哪里还能指望生存。比如人喝热汤以及吃烤炸的食物，从童年到老年，绝对没有损害人的道理。《黄帝内经》说饮食肥甘厚味的变化，只会引发痈疽，何况因肥甘厚味发痈疽的，百人中不到一两个。所以知道热性食物滋养人，时刻都不能缺少。如果用冷水给人喝，不需要三天，就会腹痛腹泻，脾虚胃败了。所以燧人氏制定法则，饮食必须用火加工，万代百姓得以活命。世俗医生大量使用凉剂，好比给人喝冷水，暗中伤害百姓，实在令人感慨。没看到当今的医家，祸及子孙甚至灭门绝后，都是医术不精的报应。（医者看到这些必须深刻反省，误用凉药的危害真实无误，我见近代时医专门使用温平药物的，或许能延续一口气，最终也见衰败。专门用寒凉攻伐，夭折人命的，确实没见过他们有后代。）
Among the four hundred and eight diseases, heat patterns are predominantly numerous, while cold patterns are the least common. It is no wonder that Liu Wansu (Liu Hejian) emphasized the discussion of Fire, and Zhu Danxi advocated nourishing Yin. However, adhering rigidly to the works of these two masters without investigating the *Huangdi Neijing* (Yellow Emperor's Inner Canon) leads to bias, causing severe harm to people. Heat diseases belong to Yang; Yang pathogens are easy to disperse and treat, and do not lead to death. Cold diseases belong to Yin; Yin pathogens are prone to latent concealment, thus causing no immediate awareness in patients. Over time, they transform into deficiency-cold, eroding the Zang-Fu organs and leading to death.
(Cases where symptoms are imperceptible at the onset are particularly harmful; often neglected, they frequently change rapidly, resulting in many deaths.)
Moreover, it is natural for the human body to possess abundant Fire. Among the Six Qi (Six Atmospheric Factors) of Heaven, Fire accounts for two. Modern mediocre physicians cling to the saying "Strong Fire consumes Qi" (from the *Neijing*). The concept of "Strong Fire consumes Qi" in the *Neijing* implies that just as intense summer heat exhausts human vitality, and excessive Ministerial Fire damages True Yuan, it does not refer to treatment with cooling herbs nor heating herbs. Ma Yuantai failed to grasp this principle and made arbitrary annotations, leaving significant errors for future students. They indulge in bitter-cold agents for nourishing Yin, failing to realize that when pathogens invade the body, sufficient Original Qi can resist them. Using cooling medicines to freeze the body instead drains the Original Qi, which is akin to assisting a thief in harming the master. Cooling medicines have undoubtedly harmed countless people. If Original Qi is slightly deficient, individuals will be frozen and destroyed by cooling medicines; with damaged Spleen and Stomach, how can survival be expected? For instance, drinking hot soup or eating roasted and fried foods from childhood to old age causes no harm. The *Neijing* states that changes due to rich and greasy food only lead to carbuncles and sores; moreover, among those who develop sores from such diet, less than one in a hundred does so. Thus, we know that heat-nourishing substances are indispensable at all times. Conversely, if one drinks cold water, within three days, abdominal pain and diarrhea will occur, leading to Spleen deficiency and Stomach failure. Therefore, Suiren established laws requiring fire for cooking, allowing generations of people to survive. Secular doctors extensively use cooling prescriptions, which is like forcing people to drink cold water, secretly harming the populace—a matter worthy of deep sigh. Have you not seen contemporary physicians whose misdeeds extend to their descendants, even wiping out entire families? This is the retribution for imprecise medical knowledge. (Physicians must reflect deeply upon reading this: the harm of mistakenly using cooling medicines is undeniable. I have observed that modern physicians who exclusively use warm and neutral methods may prolong life temporarily but ultimately face decline. Those who exclusively use cold and cool attacking methods to cut short lives certainly have no descendants.)
