夏禹铸说：热疟的发热症状，与伤寒没有区别，最难辨别。如果没有真正的传承和慧眼，将热疟当作伤寒或惊风来治疗的情况，十有八九都会出错。即使询问普天下的医生能辨别此症的人，我知道必定不多。我考察先父的医案，治愈的患者不下数千人，其中的诊法记载得非常详细，治疗方法也看似平常，但治疗效果必然显著。古人所说的药物使用得当便能通神，指的就是这种情况。我遵循先父的辨别方法，一见便知，自信程度不亚于双镜照胆（形容洞察秋毫），一药便愈，人们无不惊叹道：“奇症奇医。”然而其实并无奇特之处，只是人们辨别得不真切，所以用药无效。现在我公布辨别疟疾的秘密，传授给我的同行，使婴儿不因热疟而受苦，这样或许可以向名医卢医告无罪了。
伤寒的发热，每天到了晚上不减一分，也不增一分，始终毫不间断，只是平平地发热，不抽搐、不惊厥，这是伤寒的发热。惊风的发热似乎像伤寒，但多了一个抽搐的症状。这是因为筋脉归属于肝，肝风内动导致抽筋。肝风传入脾脏，脾动生痰，所以出现惊厥。这就是惊风发热的辨别要点。
热疟的发热虽然相同，但症状实际上有区别。有的患儿喝滚烫的茶水或汤水，或者大哭大叫，头面部一定有汗。一旦出汗，发热就会退去二三分，过了一会儿又恢复原状，这就是热疟，这是第一种辨别方法。
从早到晚一定有一个时辰病情加重，或者眼睛泛白上翻，或者手足抽搐，一抽搐出汗后发热就退去，唯独腹部不退热，过了一会儿又发烧，每天都这样，一定是热疟，这是第二种辨别方法。
喉咙里一定有痰，一哭就会呕吐，呕吐出来的是痰，一定是热疟。如果是惊风，痰浊盘踞在肺部，一定不会到达胃部，怎么会吐出来呢？这是第三种辨别方法。
具有灵心慧眼的医生不需要辨别这些，只需一眼望去便知。面色非黄似黄，非白似白，精神看似疲倦又不疲倦，面色惨淡而没有润泽，毛孔松散而不直立，两眼注视人时却像个没病的样子，热疟的症状昭然若揭。此症多发于五、六、七、八、九月之间，使用清脾饮没有不有效的。发病一两天的，一定要服用五六剂；发病至五六天的，只需要三四剂。也有误作惊风或伤寒治疗的，甚至拖延到十天二十天，乃至一个月不愈，此时只需要一二剂即可，千万不要因为一剂不愈就当作其他病症，更换方剂而误杀人性命。不知情的人难怪会指鹿为马，在我父子两代的治疗中屡屡验证，黑白分明。现在把金针远度（比喻传授秘诀），何难巧绣鸳鸯（比喻轻松解决问题）。
又有热疟是一天烧一次，发热有固定时间，其征候不冷，一来只发热，或者从下午开始直到半夜，出汗便缓解，手心、肚腹的热不能完全退尽。或者不是从下午发作，不可拘泥于此，也使用清脾饮。以上所述的热疟，如果小儿身体瘦弱怯懦，热退后可能变得虚弱甚至濒死，必须使用六君子汤以补益脾气。
后面的杂症案例，我大半出自书本流传，只是在疑惑之处进行辨别，经验确切的记录下来，无效的删去，对于书中未传见的症状想出治疗方法，不过占四成五。唯独惊风类以及热疟、脐风的辨别方法前所未传，推拿的方法也有错误。我父子两代在七十多年中，因症生悟，由悟入神，一见便知，一药便愈。这难道不就是所谓“前无古而后无今”吗？现在拿出兰亭真本（比喻珍贵的原作），千万不要把它视为枫落吴江（比喻平庸之作）。
凡是病症用药不过一到三味，甚至八到九味为限度，唯独惊痫症用到十九味，为什么呢？只因群邪逞势，各脏腑受灾，病邪深入内地，无处不受害，上至头顶，下至厥阴经，手、足、腹、心到处波及，所以攻坚削乱的兵力不可缺其一，正如王翦伐楚预先知道非六十万人不能攻克一样，说的就是这个道理。各位儿科医生千万不要把天保采薇汤当作八寸三分帽，让所有人都戴啊。
Xia Yuzhu said: The fever of Heat Malaria (Re Nue) is indistinguishable from Cold Damage (Shang Han), making it the most difficult to differentiate. Without true transmission and wisdom's eye, treating Heat Malaria as Cold Damage or Convulsive Disease (Jing Feng) results in errors in nine out of ten cases. Even if one asks physicians across the world who can distinguish this syndrome, I know there will be few. I have examined my father's medical records, where he cured thousands of patients; the diagnostic methods are recorded in great detail, and the treatments seem ordinary, yet they are invariably effective. This is what the ancients meant by "when herbs are used appropriately, they achieve miraculous effects." Following my father's differentiation method, I recognize it at a glance, with confidence akin to looking at one's gallbladder through double mirrors (seeing clearly), curing with a single prescription. People marvel, saying, "Miraculous disease, miraculous doctor." However, there is nothing miraculous; people simply fail to differentiate accurately, hence the ineffectiveness of medication. Now, I reveal the secret of differentiating malaria to my colleagues, so that infants may suffer less from Heat Malaria, thus perhaps absolving myself before the famous physician Lu Yi.
The fever of Cold Damage persists without increasing or decreasing by even a fraction until evening, uninterrupted throughout, presenting as a steady, flat fever without convulsions or fright. This is the fever of Cold Damage. The fever of Convulsive Disease resembles that of Cold Damage but is accompanied by convulsions. This is because tendons belong to the Liver; when Liver Wind moves internally, it causes cramping. When Liver Wind enters the Spleen, the Spleen stirs phlegm, leading to fright. This distinguishes the fever of Convulsive Disease.
Although the fever of Heat Malaria appears similar, the symptoms differ. Some children drink boiling tea or soup, or cry and shout loudly, with sweat necessarily appearing on the head and face. Once sweat appears, the fever subsides by two or three points, only to return to its original state shortly after. This is Heat Malaria—this is the first method of differentiation.
From morning to night, there is always one period when the condition worsens, such as the eyes rolling up or limbs twitching. After a twitch and subsequent sweating, the fever subsides, but heat remains in the abdomen. Shortly after, the fever returns, occurring daily. This is definitely Heat Malaria—this is the second method of differentiation.
There must be phlegm in the throat; crying induces vomiting, and upon vomiting, phlegm is expelled. This is definitely Heat Malaria. In contrast, in Convulsive Disease, phlegm stagnates in the Lungs and does not reach the Stomach, so how could it be vomited? This is the third method of differentiation.
Physicians with spiritual hearts and wise eyes need not differentiate these; a single glance suffices. The complexion is yellowish yet not truly yellow, whitish yet not truly white; spirit seems fatigued yet not truly fatigued; the face is dull without luster; pores are loose but not standing erect; the eyes look at people as if healthy. Thus, Heat Malaria is evident. This syndrome often occurs between the fifth and eighth months. Qing Pi Yin (Clear the Spleen Decoction) is invariably effective. For those who have been ill for one or two days, five or six doses are required; for those ill for five or six days, three or four doses suffice. Some are mistakenly treated as Convulsive Disease or Cold Damage, lasting ten, twenty days, or even a month. In such cases, only one or two doses are needed. Do not change the formula due to lack of immediate effect, lest you cause death by error. Those unaware may mistake deer for horses, but in my father's and my generations of treatment, the distinction has been clear as black and white. Now, passing on the golden needle (metaphor for secret knowledge), solving problems becomes as easy as embroidering mandarin ducks.
Another type of Heat Malaria involves once-daily fever with a fixed schedule, characterized by no chills, starting with fever only, either from afternoon until midnight, resolving with sweat, though heat in palms and abdomen may not fully resolve. If it does not start in the afternoon, do not be rigid; still use Qing Pi Yin. For the above-mentioned Heat Malaria, if the child is emaciated and weak, and after fever subsides becomes critically weak or near death, Liu Jun Zi Tang (Six Gentlemen Decoction) must be used to tonify Spleen Qi.
Regarding subsequent miscellaneous cases, I mostly drew from existing texts, differentiating only where doubts arose, recording empirical successes, deleting ineffective ones, and devising treatments for symptoms not previously recorded, accounting for about 40-50% of the content. Only the differentiation methods for Convulsive Disease, Heat Malaria, and Umbilical Wind were unprecedentedly transmitted; massage techniques were also corrected. Over seventy years, my father and I gained insight from diseases, entering a state of spiritual clarity, recognizing instantly and curing with one prescription. Is this not what is meant by "before us, no ancients; after us, no moderns"? Now presenting the authentic edition of Lanting (Orchid Pavilion), do not treat it as mediocre work.
Generally, herbal prescriptions contain one to three ingredients, up to eight or nine. However, prescriptions for Convulsive Epilepsy may contain up to nineteen ingredients. Why? Because pathogenic factors overwhelm, affecting all organs, penetrating deep into the interior, harming everywhere—from the vertex to the Jueyin channel, spreading to hands, feet, abdomen, and heart. Therefore, troops for attacking fortifications and quelling chaos cannot be lacking, just as Wang Jian knew that conquering Chu required six hundred thousand troops. Pediatricians must not treat Tian Bao Cai Wei Tang (Heavenly Preservation and Gathering the Fern Decoction) as a universal hat for everyone to wear.
