经曰∶夏伤于暑，秋必 疟。其证初起，呵欠顿闷，发热口渴，面带黄白，头额有汗，一哭汗出，其热渐退
二三分，不久复热如故，喉内痰鸣，一哭即呕，呕则痰出，每日如此者，即疟证也。
按∶《内经》谓十二经皆有疟，究其所因，而大要不离乎少阳胆经。夫疟之不离乎少阳，犹咳嗽之不离乎
肺也。盖凡寒热往来，总为少阳所主。早能和解表里，分理阴阳，则疟邪霍然而散；由其误认惊风，轻施镇坠，以
致正邪激搏，荣卫迟留。阳欲入里，阴内阻之；阴欲出表，阳外遏之。少阳欲升不得升，太阴欲降不得降，乃致
精神溃乱，临疟而搐。宜清脾饮解之，其搐自止。
清脾饮 治小儿热疟作搐，不必治搐，惟治其疟。

按∶此证虽曰内伤饮食，莫不由于外感而发也。有至妙之治，人所不知，但以人参败毒散升散之，其病即

《黄帝内经》说：夏季感受暑邪，秋季必定发生疟疾。其症状在初起时，表现为打哈欠、突然感到胸闷，发热且口渴，面色呈现黄白色，头额部位有汗出，孩子一哭就有汗出，热度随之减退二三分，但不久后热度又恢复如初，喉咙内有痰鸣声，一哭就会呕吐，呕吐后痰液排出，每天如此反复的，就是疟疾病证。
按语：《黄帝内经》指出十二经都可能发生疟疾，但究其病因，大要离不开少阳胆经。疟疾离不开少阳经，就像咳嗽离不开肺脏一样。凡是寒热往来的症状，总归由少阳经所主。若能早期采用和解表里、分理阴阳的方法治疗，疟邪就会迅速消散；如果误认为是惊风，轻易使用镇惊坠痰的药物，导致正气与邪气激烈搏结，营卫之气运行迟滞。阳气想要进入体内，却被阴气在内阻遏；阴气想要出于体表，却被阳气在外遏制。少阳经的气机想要上升却无法上升，太阴经的气机想要下降却无法下降，从而导致精神神志溃乱，在发作疟疾时出现抽搐。适宜用清脾饮来解除病邪，抽搐自然停止。
清脾饮：治疗小儿热疟引发抽搐，不必专门治疗抽搐，只需治疗疟疾即可。

《黄帝内经》说：饮食不节制，起居没有规律，邪气侵犯阴分则进入五脏，向下发展为完谷不化的泄泻，日久则成为痢疾。其症状在初起时，表现为双眉紧皱且多啼哭，这是由于腹痛所致；烦躁不安，是由于里有急迫感和排便后仍有便意（里急后重）所致；频繁去厕所却排不出大便，或者大便中红白相兼，或者只有红色或只有白色，这就是痢疾的征候。
按语：此病证虽然说是内伤饮食引起，但没有不是由于外感邪气诱发而发作的。有一种极其高明的治疗方法，世人并不知晓，只要用人参败毒散升提发散邪气，病情就会减轻。如果有饮食停滞的情况，轻症用消食导滞的方法，重症用疏通的方法，去除体内的积滞污垢，没有不能治愈的。愚昧的人不加考察，反而投用诃子、豆蔻等收敛止涩的药物，导致积滞毒素郁结在内，出现腹痛和里急后重，想上厕所却排不出来。这是应当“通因通用”（以通治通）的病证，却反而用了“通因塞用”（以塞治通）的方法，于是导致神志昏迷、烦躁扰动的情况就出现了。此时急需同时服用沆瀣丹和三仙丹两种药物，待肠道疏通之后，疾病自然消除：
The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states: "Summer injury by heat (Shu), autumn must have malaria." Its symptoms at the onset include yawning and sudden chest stuffiness, fever with thirst, a yellowish-white complexion, sweating on the forehead, and sweating upon crying, after which the fever subsides slightly. However, the fever returns to its original state shortly thereafter. There is phlegm rattling in the throat, vomiting upon crying, and expulsion of phlegm after vomiting. If this occurs daily, it is identified as a malaria syndrome.
Commentary: The *Neijing* states that malaria can occur in all twelve meridians. Investigating its etiology, the primary mechanism invariably involves the Shaoyang Gallbladder Meridian. Malaria's association with the Shaoyang meridian is akin to coughing's association with the Lung. Generally, alternating chills and fever are governed by the Shaoyang. If one can early on employ methods to harmonize the exterior and interior, and differentiate yin and yang, the malaria pathogen will dissipate rapidly. However, if mistakenly diagnosed as convulsive disorder (Jing Feng) and treated lightly with sedative and descending agents, it leads to intense struggle between healthy qi and pathogenic factors, causing stagnation of Ying (Nutritive) and Wei (Defensive) qi. Yang desires to enter the interior but is blocked by Yin within; Yin desires to emerge to the exterior but is restrained by Yang outside. The Shaoyang Qi cannot ascend, and the Taiyin Qi cannot descend, resulting in mental confusion and convulsions during malaria attacks. It is appropriate to use Qingpi Yin (Clear the Spleen Decoction) to resolve the condition, after which the convulsions will cease naturally.
Qingpi Yin (Clear the Spleen Decoction): Treats pediatric malaria with heat inducing convulsions. There is no need to treat the convulsions directly; only treat the malaria.

The *Huangdi Neijing* states: "Irregular diet and improper living habits, if affecting the Yin, enter the five zang organs, manifesting downward as undigested diarrhea (Sun Xie), and over time becoming dysentery (Chang Li)." Its initial symptoms include furrowed eyebrows and frequent crying due to abdominal pain; restlessness and anxiety due to tenesmus (Li Ji Hou Zhong); frequent trips to the toilet with inability to defecate, or stool mixed with red and white blood, or purely red or purely white, are the indicators of this condition.
Commentary: Although this syndrome is described as internal injury from diet, it invariably arises triggered by external pathogens. There is an exquisite treatment unknown to many: simply using Renshen Baidu San (Ginseng Detoxification Powder) to lift and disperse the pathogen, and the illness will subside. If there is food stagnation, mild cases are treated with digestion-promoting and guiding methods, while severe cases are treated with unblocking and draining methods to remove accumulated filth; none fail to heal. Ignorant practitioners, failing to observe correctly, instead administer astringents like Hezi (Terminalia Chebulae Fructus) and Doukou (Amomi Fructus Rotundus), leading to internal depression of accumulated toxins, causing abdominal pain and tenesmus with inability to defecate. This is a case requiring "treating obstruction with unblocking agents" (Tong Yin Tong Yong), yet they erroneously use "treating unblocking with obstructing agents" (Tong Yin Sai Yong), resulting in cases of coma and agitation. Urgently administer Hangxie Dan and Sanxian Dan together. After the bowels are unblocked, the disease will naturally depart:
