如今，对于年轻且已婚的人，一旦发热，若治疗无效，医生必定将其诊断为“夹阴证”，转而使用附子、肉桂、人参、地黄等大热大补的药物来致其于死地。病人家属也责怪患者不慎，而不怨恨医生的误治，因此医生乐于谈论夹阴证，以此作为推卸责任的借口，导致冤死者众多。如果有父母在，或许会归咎于儿媳，而患者无法辩白，于是含恨轻生，造成的罪孽岂能说得完！不知道在房事劳累或遗精之后，感受风寒，病邪也必然从太阳经传入，仍然属于阳邪，其热势必然很盛，兼有烦躁闷乱、心烦口渴等症状，尤其应当清热散邪，怎么可以反而使用热性药物呢！
炳按：房事之后患病发热，称为夹阴证。然而自古以来不信此说的人很多。考证《张氏医通》、《伤寒缵绪》，其中有夹阴一条，认为必须伴有外症少腹疼痛、生殖器收缩、足胫发冷才是真证。出自小建中汤加减炒制后使用。但张景岳说：真正的伤寒可以治疗，三时（春、夏、秋）发生的这类病，即使长沙王（指张仲景）复生，也不能辨认。有上述见证的，确实有此病，虽然少腹痛减轻，足胫已暖，生殖器已伸展，仍然不能救活。这是我亲手治疗的案例。叶天士说：病前病中耗损精气的人，阴气先受伤，如寒冷时觉得寒邪极盛，发热时觉得热势炽烈，（这是初起时日浅），等到病情严重化热，津液必然容易枯竭，这都是内虚，阳邪传入阴经，即使不死，伤寒也偏死于下元虚弱之人。古语也说这不是几剂药就能治愈的病症。如果使用桂枝、附子、人参、地黄，必然会导致胸闷恶心、食欲减退、烦热，但是大热大补的药物，阴虚体质的人服用，无病也会生出病来。徐灵胎当时与叶氏争名。著作也说得过分严重，像先生您一样罢了，读书自然要有自己的眼光，双眼自将秋水洗净，一生不受古人欺骗。这是袁子才的诗句，我非常佩服。
如果真的是中了三阴经（太阴、少阴、厥阴），那么绝对没有壮热的道理，一定会有恶寒倦卧、四肢厥冷喜热等症状，才可以温散。然而终究不能用滋补的方法。徐洄溪论述得很详细了。奉劝医生不要轻易言及夹阴以害人，病人家属不要轻信夹阴以自害。按照证候施治，不要惊慌失措，这样天下多救活一个人，地下就少一个冤鬼，也是相得益彰的道理啊。至于“夹阴”这两个字，本来属于庸人杜撰，放在一边不予辩驳就可以了。
Nowadays, for young married individuals who develop fever, if the treatment is ineffective, physicians invariably diagnose it as "Jia Yin Syndrome" (Syndrome of Intercourse-Induced Pathogen Entrapment) and switch to using large doses of strongly heating and tonifying herbs such as Fuzi (Aconiti Lateralis Radix Praeparata), Guizhi (Cinnamomi Ramulus), Renshen (Ginseng Radix et Rhizoma), and Dihuang (Rehmanniae Radix Preparata), thereby causing their death. The patient's family blames the patient for carelessness rather than resenting the physician for misdiagnosis. Thus, physicians are eager to mention Jia Yin Syndrome as an excuse to evade responsibility, resulting in numerous unjust deaths. If there are parents present, they may blame the daughter-in-law, while the patient cannot defend themselves, leading to resentment and suicide; the karmic retribution involved is immeasurable. They do not realize that after sexual exhaustion or nocturnal emission, if one contracts wind-cold, the pathogen must enter via the Taiyang Channel (Taiyang Meridian), still belonging to Yang pathogens. The heat will be severe, accompanied by restlessness, oppression, irritability, and thirst. Such cases especially require clearing heat and dispersing pathogens. How can one reverse course and use hot-natured medicines?
Bing notes: Fever occurring after sexual intercourse is termed Jia Yin Syndrome. However, many have doubted this since ancient times. Consulting *Zhang Shi Yi Tong* (Comprehensive Medical Records of Master Zhang) and *Shanghan Zuanshu* (Elucidation of Cold Damage Treatise), there is a section on Jia Yin Syndrome, stating that true cases must present with external symptoms of lower abdominal pain, retraction of the genitalia, and coldness in the calves and shins. The prescribed treatment involves modifications of Xiao Jian Zhong Tang (Minor Construct the Middle Decoction), processed by stir-frying. However, Zhang Jingyue stated: True Shanghan (Cold Damage) is treatable, but for illnesses of this nature occurring in the three seasons (spring, summer, autumn), even if Changsha Wang (referring to Zhang Zhongjing) were reborn, he could not identify them. For those presenting with the aforementioned symptoms, although the lower abdominal pain subsides, the calves warm up, and the genitalia extend, recovery is impossible. I have treated such cases personally. Ye Tianshi said: Individuals who lose essence before or during illness suffer initial injury to Yin Qi. When cold, they feel extreme cold; when hot, they feel intense heat (this indicates the early stage). As the condition worsens and transforms into heat, body fluids easily dry up. These are all cases of internal deficiency where Yang pathogens transmit into Yin channels. Even if not fatal, Shanghan tends to kill those with deficiency in the lower jiao. Ancient sayings also indicate this is not a condition curable by a few doses. Using Guizhi, Fuzi, Renshen, and Dihuang will inevitably cause chest tightness, nausea, reduced appetite, and irritability. For individuals with Yin deficiency constitutions, taking such strongly heating and tonifying drugs will create disease where none existed. Xu Lingtai competed for fame with Ye Tianshi at the time. His writings also exaggerated excessively, similar to your own style. One must read with independent judgment: "Wash your eyes clear as autumn water, so you are never deceived by ancients in your life." This is a verse by Yuan Zicai, which I deeply admire.
If one truly suffers from transmission to the Three Yin Channels (Taiyin, Shaoyin, Jueyin), there would absolutely be no high fever. There must be symptoms such as aversion to cold, fatigue, lying down, cold extremities, and preference for warmth, only then can warming and dispersing methods be used. However, tonification methods should ultimately not be employed. Xu Huixi discussed this in detail. I advise physicians not to lightly speak of Jia Yin Syndrome to harm others, nor for patients' families to blindly believe in Jia Yin Syndrome to harm themselves. Treat according to the syndrome differentiation without panic. In this way, more lives will be saved in the world, and fewer wronged ghosts will exist in the underworld, achieving mutual benefit. As for the term "Jia Yin," it was originally fabricated by mediocre practitioners and can simply be ignored without debate.
