痧者，火毒也。若犯痧症，适与心主之火相合，故痧毒逆冲，最要防攻心之患。今少阴心君不受邪，逆犯厥阴肝母，
故两目红肿如桃，甚则眼珠突出，最为凶险。然他症患目，惟在于目，若因痧为患，必然先觉心中烦闷而目疾因之。苟
不知早治，则痧毒已参阳位，其火势之炎热，轻则坏目，重则殒命。治宜先刺巅顶百会穴，以泄毒瓦斯，当放者放，刮者
刮，
用清火活血顺气之剂，加牛膝、石斛以引火归原，诚为良法。

左脉微细无根，痧毒之为害也。放痧不愈，用金银花、茜草、连翘、黑山栀、枳壳、丹皮、赤芍、牛膝、石斛、草决明，

寒气郁伏于肌肤、血肉之间，至春而发，变为瘟症，是
名瘟痧。又暑热伤感，凝滞于肌肤血肉之中，至秋而发，亦名瘟痧。但春瘟痧毒受病者少，不相传染，时或有之。秋瘟
痧毒受病者多，老幼相传，甚至一家数人犯痧，或一方数人犯痧。其发也，必恶寒发热。或腹痛，或不腹痛，似疟非疟，
或气急发喘，头面肿胀，胸腹饱闷，或变下痢脓血，轻者牵连岁月，重者危急一时。治宜放痧消食积为主，俟痧毒已泄，

一洪公震九月，恶寒发热，吐痰咳嗽，胸中烦闷，口渴舌苔。延余诊之，左脉时有歇指，右脉沉而有力。刺痧筋，
毒血不流，后卧床不醒，益觉沉重，此误饮热汤为害也。用阴阳水一碗，加明矾二分饮之，又用消食去积之药，加熟

一公震内室，同时恶寒发热，头面肿胀，心胸烦闷，似大头瘟。诊之，六脉俱伏，此瘟痧也。放痧不愈，先饮微冷
矾汤，次用透窍消毒下气之剂，加牛膝三钱同煎，微冷冻饮料之，二服全愈。
一公震次子十月，寒热如疟，心腹绞痛，吐泻不已，六脉沉紧，亦瘟痧为害也。用沉香阿魏丸，清茶微冷下，并和

痧症，本质上是火毒。如果感染痧症，其邪气恰好与心主之火相合，因此痧毒逆冲上攻，最需要防范的是攻心的祸患。如今少阴心君不受邪气侵袭，反而逆犯厥阴肝木（此处原文“肝母”疑为“肝木”之误，指肝脏），所以双眼红肿如桃子，严重时眼珠突出，最为凶险。然而其他病症引起的眼部不适，病位仅在眼睛；若是因痧症致病，必然先感到心中烦闷，随后才引发眼疾。如果不尽早治疗，痧毒就会侵犯阳位（头部及上部），火势炎热，轻则毁坏双目，重则导致死亡。治疗应当先针刺头顶的百会穴，以泄出毒瓦斯，该放血的就放血，该刮痧的就刮痧，使用清火、活血、顺气的药剂，加入牛膝、石斛以引火归原，这确实是良法。
治验案例：
有一位江道诚，患病后心中烦热，头晕目眩，忽然双眼红肿剧痛，饮用热茶或热酒后眼珠突出，左眼尤其严重，到了晚上就昏沉发晕。请我诊治，发现左脉微细无根，这是痧毒造成的危害。进行放痧治疗后未愈，于是用金银花、茜草、连翘、黑山栀、枳壳、丹皮、赤芍、牛膝、石斛、草决明，加入童便（童子尿）微冷冻后服用，眼珠才收回，经过调理而痊愈。
寒气郁结潜伏在肌肤、血肉之间，到了春天发作，变为瘟症，这就叫作瘟痧。又是暑热感受外邪，凝滞于肌肤血肉之中，到了秋天发作，也叫作瘟痧。但是春季瘟痧毒受病的人较少，不互相传染，偶尔才有发生。秋季瘟痧毒受病的人多，老幼相传，甚至一家数人感染痧症，或一个地方数人感染痧症。其发作时，必定恶寒发热。或者腹痛，或者不腹痛，似疟疾非疟疾，或者气急喘息，头面肿胀，胸腹饱闷，或者变为下痢脓血，轻者拖延岁月，重者一时危急。治疗应当以放痧、消食积为主，等到痧毒已泄，然后和解清理，去除寒热，健脾养血，补益其中气虚弱。
治验案例：
洪公震在九月间，恶寒发热，吐痰咳嗽，胸中烦闷，口渴舌苔厚腻。请我诊治，左脉时有歇止，右脉沉而有力。刺痧筋（皮下浅表静脉），毒血不流，后来卧床不醒，更加觉得沉重，这是误饮热汤造成的危害。用阴阳水一碗，加入明矾二分服用，又用消食去积的药物，加入熟大黄一钱，微冷冻后服用，稍见好转。第二天痧筋再次显现，刺臂弯一针，十指二十二针，排出毒血，使用活血解毒药，各种症状逐渐缓解，经过调理而痊愈。
洪公震的妻子，同时出现恶寒发热，头面肿胀，心胸烦闷，类似大头瘟。诊察发现六脉俱伏，这是瘟痧。放痧治疗未愈，先饮用微冷的矾汤，接着使用透窍、消毒、下气的药剂，加入牛膝三钱同煎，微冷冻后服用，两服后完全痊愈。
洪公震的次子在十月间，寒热如疟疾，心腹绞痛，呕吐腹泻不止，六脉沉紧，也是瘟痧造成的危害。使用沉香阿魏丸，用清茶微冷送服，并配合和脾宣化饮，加入大黄一钱，同煎微冷冻后服用，第二天再按前法服用，从而痊愈。
Sha disease is essentially fire-toxin. If one contracts Sha disease, the pathogen coincides with the Fire of the Heart Master; thus, the Sha toxin rushes upward in rebellion, and the most critical precaution is to prevent the disaster of attacking the Heart. Currently, the Shao Yin Heart Monarch does not accept pathogens but instead rebels against the Jue Yin Liver Wood (note: original text "Liver Mother" is likely a typo for "Liver Wood", referring to the Liver), causing both eyes to become red and swollen like peaches, and in severe cases, the eyeballs protrude, which is extremely perilous. However, eye ailments caused by other diseases are localized to the eyes; if caused by Sha disease, one must first feel mental restlessness and heat, followed by the onset of eye pathology. If early treatment is neglected, the Sha toxin will invade Yang positions (the head and upper body); the intense heat of the fire will, in mild cases, ruin the eyes, and in severe cases, cause death. Treatment should begin by puncturing the Baihui acupoint on the vertex to vent the toxic vapors; perform bloodletting where indicated, and scraping where indicated. Use formulas that clear fire, invigorate blood, and regulate Qi, adding Niuxi (Achyranthes Root) and Shihu (Dendrobium Stem) to guide the fire back to its source. This is indeed an excellent method.
Clinical Case 1:
Jiang Daocheng suffered from mental restlessness and heat, dizziness, and suddenly developed severe redness, swelling, and pain in both eyes. After drinking hot tea or hot wine, his eyeballs protruded, especially the left eye. By evening, he became lethargic and dizzy. Upon my examination, the left pulse was faint, fine, and rootless, indicating harm caused by Sha toxin. Bloodletting alone did not cure him. I prescribed Yinhua (Honeysuckle Flower), Qiancao (Rubia Root), Lianqiao (Forsythia Fruit), Heishanzhi (Gardenia Fruit), Zhike (Bitter Orange), Danpi (Moutan Cortex), Chishao (Red Peony Root), Niuxi (Achyranthes Root), Shihu (Dendrobium Stem), and Caojueming (Cassiae Semen), added with Tongbian (Child's Urine). The mixture was cooled slightly before administration. His eyeballs eventually retracted, and he recovered after conditioning.
Cold Qi stagnates and hides between the skin, flesh, and muscles. When spring arrives, it erupts, transforming into a Plague Disease, known as "Wen Sha" (Plague Sha). Alternatively, Summerheat-Heat injury condenses within the skin, flesh, and muscles, erupting in autumn, also called "Wen Sha." However, few contract Spring Wen Sha toxin; it is not contagious and occurs occasionally. Many contract Autumn Wen Sha toxin; it spreads among old and young, sometimes affecting several members of one family or several people in one locality. Onset is characterized by aversion to cold and fever. There may be abdominal pain or no pain, resembling malaria but not quite, or rapid breathing and wheezing, swelling of the head and face, fullness and oppression in the chest and abdomen, or dysentery with pus and blood. Mild cases drag on for months or years; severe cases are critically urgent. Treatment should primarily focus on bloodletting/scraping (Fang Sha) and resolving food stagnation. Once the Sha toxin is vented, then harmonize and clear, eliminating cold and heat, strengthening the Spleen, nourishing Blood, and tonifying Middle Jiao deficiency.
Clinical Case 2:
In September, Hong Gongzhen experienced aversion to cold and fever, expectoration and cough, chest oppression, thirst, and coated tongue. My examination revealed an intermittent left pulse and a deep, forceful right pulse. Puncturing the Sha veins (superficial collateral vessels) failed to release toxic blood. He subsequently lay bedridden and unconscious, feeling increasingly heavy. This was harm caused by mistakenly drinking hot soup. I administered one bowl of Yin-Yang Water (a mixture of boiled and unboiled water) with two fen of Mingfan (Alum). Additionally, I used herbs to resolve food stagnation, adding one qian of Shu Dahuang (Prepared Rhubarb). Taken cold, he improved slightly. The next day, the Sha veins reappeared. I punctured one point at the elbow crease and twenty-two points on the fingers to expel toxic blood. Using blood-invigorating and detoxifying herbs, his symptoms gradually relaxed, and he recovered after conditioning.
Hong Gongzhen’s wife simultaneously presented with aversion to cold and fever, swelling of the head and face, and chest/heart oppression, resembling Big Head Plague. Her six pulses were all concealed (deep and hidden). This was diagnosed as Wen Sha. Bloodletting alone was ineffective. She first drank slightly cold Alum Water, followed by a formula to open orifices, detoxify, and direct Qi downward, with three qian of Niuxi decocted together. Taken cold, she fully recovered after two doses.
Hong Gongzhen’s second son, in October, presented with chills and fever resembling malaria, severe colicky pain in the heart and abdomen, incessant vomiting and diarrhea, and deep, tight pulses. This was also harm from Wen Sha. I administered Chenxiangawei Wan (Agarwood and Asafoetida Pills), taken with cool green tea, along with Hepixuanhua Yin (Spleen-Harmonizing and Transformation Decoction) with one qian of Dahuang (Rhubarb) decocted together. Taken cold, he took the same prescription again the next day and recovered.
