痧症有恶饮热汤者，有反喜饮热汤者，惟其喜饮热汤，痧症益莫能识，慢痧所以变成劳瘵也。原其痧毒之始入于气
分，令人喘嗽吐痰发热声哑，盖火毒伤肺，肺为娇脏，若不知治变成百日紧劳，轻者数年难愈，卒至危亡。痧毒之始入
于血分，重者兆变在即，轻者岁月延挨。若乃毒瘀胃口，必须去尽而愈。毒瘀肝经，损坏内溃，吐血数发，势极多危。
毒瘀心包络，更加凶险，不待时日。毒瘀肾经，腰脊疼痛，嗽痰咯血，日甚一日，不可得痊。凡痧毒遗患，总成劳瘵，
治须识之于始，（凡脏腑之病俱可疗治，）莫咎其终。（若一溃损脏腑便属不治。）
治验∶
一王君瑞内室，咳嗽吐痰发热，左背疼痛，已年余矣。延余诊之，六脉浮紧洪数，脉症不合，又无痧筋，但用刮痧
痛减，服散痧清热消痰顺气四剂而愈。
一杨音节痧胀不服药，惟放痧三次，胃脘间成一大块，咳嗽吐痰，发热不食，日渐 瘦。延余诊之，右关脉芤而紧，
余脉俱数。余曰∶“内有瘀血，必吐出而可解。”用桃仁、苏木、泽兰、白蒺藜、香附、乌药酒煎服之，吐紫黑血碗许，
更用活血引下之剂，加童便酒服之而愈。
一左元峰痧胀，放痧三次，不服药，痧根不绝，变成劳瘵，咳嗽咯血，音哑发喘，骨瘦如柴，脉洪大无伦。余辞不
治，又二月而终。
痧症中，有的患者厌恶饮用热汤，有的反而喜欢饮用热汤。正因为患者喜欢喝热汤，导致痧症更难被识别，这也是慢痧（慢性痧症）最终演变为劳瘵（一种以虚损、咳嗽、咯血为主要表现的慢性消耗性疾病）的原因。
追溯其机理，当痧毒最初侵入气分（人体功能活动的层面），会导致患者出现气喘、咳嗽、吐痰、发热、声音嘶哑等症状。这是因为火毒损伤了肺脏，而肺被称为“娇脏”（指肺叶娇嫩，不耐寒热燥湿诸邪侵袭的脏器）。如果此时不知道及时救治，就会演变成百日紧劳（一种病程较长、病情较重的劳损病证），轻者数年难以痊愈，重者最终导致死亡。
若痧毒最初侵入血分（人体血液运行的层面），重症者危险征兆即刻显现；轻症者则拖延时日，逐渐加重。如果毒素瘀滞于胃口（胃脘部），必须将瘀毒彻底清除才能痊愈。如果毒素瘀滞于肝经，会导致内脏损坏甚至溃破，反复吐血，形势极其危险。如果毒素瘀滞于心包络（保护心脏的外围组织），情况更加凶险，不用多久便会危及生命。如果毒素瘀滞于肾经，会出现腰脊疼痛、咳嗽吐痰、咯血，且症状一天比一天严重，无法治愈。
凡是痧毒留下的后患，最终都会形成劳瘵之症。治疗的关键在于早期识别。（一般来说，脏腑的疾病都是可以治疗的，）不要等到最后才去责怪（为时已晚）。（但如果一旦脏腑发生溃烂损伤，就属于无法医治的情况。）
治验案例：
有一位王君瑞的妻子，出现咳嗽、吐痰、发热、左背部疼痛的症状，持续了一年多。请我诊治，发现六脉（寸关尺三部，左右手共六处脉搏）呈现浮、紧、洪、数四种脉象，脉象与症状不相符合，体表也没有看到痧筋（皮下显露的紫红色脉络，提示痧毒深重），但我仅用刮痧疗法，疼痛便减轻，随后服用散痧、清热、消痰、顺气四剂药方，病即痊愈。
另一位杨音节的妻子患痧胀（痧症的一种，表现为腹部胀满疼痛等），拒绝服药，只进行了三次放痧（用针具刺破皮肤或浅表静脉放出少量血液以排毒的治疗方法）治疗。之后胃脘间形成一个大肿块，伴有咳嗽、吐痰、发热、食欲不振，身体日渐消瘦。请我诊治，发现右关脉（对应脾胃的脉位）呈现芤脉（浮大中空，如按葱管）和紧脉，其余脉象均数（快）。我说：“体内有瘀血，必须通过呕吐排出才能解除。”于是使用桃仁、苏木、泽兰、白蒺藜、香附、乌药，用酒煎服。患者吐出了约一碗紫黑色的瘀血，随后又服用活血引下（引导瘀血下行排出）的药剂，加入童便（健康儿童的小便，中医认为具有滋阴降火、化瘀止血功效）和酒送服，最终痊愈。
还有一位左元峰患痧胀，进行了三次放痧，拒绝服药，导致痧根未除，演变成劳瘵。出现咳嗽、咯血、声音嘶哑、气喘，身体瘦弱得像柴火一样，脉象洪大无比。我推辞说无法治疗，两个月后他去世了。
In Sha syndrome (a disease caused by "Sha" toxin, often manifesting as acute abdominal pain or skin eruptions), some patients dislike drinking hot water, while others prefer it. It is precisely because they prefer hot water that Sha syndrome becomes difficult to identify, which is why slow Sha (chronic Sha) eventually transforms into Lao Zhai (a chronic consumptive disease characterized by deficiency, cough, and hemoptysis).
Tracing the mechanism, when Sha toxin initially enters the Qi level (the functional aspect of the human body), it causes symptoms such as panting, coughing, expectoration, fever, and hoarseness. This is because fire-toxin damages the Lung. The Lung is known as the "delicate organ" (referring to its tender nature, making it susceptible to cold, heat, dryness, dampness, and other pathogens). If timely treatment is not administered, it may develop into Bai Ri Jin Lao (a prolonged and severe consumptive condition). Mild cases may take years to heal, while severe cases lead to death.
If Sha toxin initially enters the Blood level (the circulatory aspect of the human body), critical cases show imminent danger signs, while mild cases drag on over time, gradually worsening. If the toxin stagnates in the stomach region (epigastrium), complete removal of the stasis-toxin is required for recovery. If the toxin stagnates in the Liver Meridian, it causes internal damage and ulceration, with recurrent hematemesis, presenting an extremely critical situation. If the toxin stagnates in the Pericardium (the protective outer layer of the heart), the condition is even more perilous, leading to death without much delay. If the toxin stagnates in the Kidney Meridian, it results in lower back and spine pain, coughing with expectoration and hemoptysis, worsening day by day, making recovery impossible.
Any sequelae left by Sha toxin ultimately form Lao Zhai. The key to treatment lies in early identification. (Generally speaking, diseases of the Zang-Fu organs are treatable,) so do not blame the outcome at the end stage. (However, once the Zang-Fu organs suffer ulcerative damage, the condition becomes incurable.)
Clinical Cases:
1. The wife of Mr. Wang Junrui suffered from cough, expectoration, fever, and left back pain for over a year. Upon consultation, her six pulses (cun, guan, chi positions on both hands) were floating, tight, surging, and rapid. The pulse did not match the symptoms, and no Sha veins (purple-red subcutaneous vessels indicating deep Sha toxin) were visible. However, after scraping therapy (Gua Sha), the pain decreased. She was prescribed four doses of formulas to disperse Sha, clear heat, resolve phlegm, and regulate Qi, resulting in a cure.
2. Mrs. Yang Yiejie suffered from Sha distension but refused medication, undergoing only three rounds of bloodletting (Fang Sha, a method of puncturing skin or superficial veins to release blood for detoxification). Subsequently, a large mass formed in her epigastrium, accompanied by cough, expectoration, fever, anorexia, and gradual emaciation. Upon consultation, her right Guan pulse (corresponding to the Spleen and Stomach) was knifelike (Kou pulse, floating, large, and hollow) and tight, while the remaining pulses were rapid. I stated, "There is intra-abdominal blood stasis; it must be vomited out to resolve." I prescribed a decoction of Peach Kernel (Tao Ren), Sappan Wood (Su Mu), Agrimony (Ze Lan), Tribulus Fruit (Bai Ji Li), Cyperus Rhizome (Xiang Fu), and Linderia Bark (Wu Yao), brewed with wine. She vomited approximately one bowl of dark purple-black blood. Subsequently, she took a formula to invigorate blood and guide stasis downward, taken with child's urine (Tong Bian, used in TCM for its yin-nourishing, fire-clearing, and stasis-resolving properties) and wine, leading to recovery.
3. Mr. Zuo Yuanfeng suffered from Sha distension. After three rounds of bloodletting and refusing medication, the root of the Sha toxin remained, transforming into Lao Zhai. Symptoms included cough, hemoptysis, hoarseness, panting, and extreme emaciation ("skin and bones"). His pulse was excessively surging and large. I declined to treat him due to the poor prognosis, and he passed away two months later.
