江汝洁治一妇人。患上身至头面俱痒。刺痛起块。众医皆谓大风等证。江诊得左手三部
俱细。右手三部皆微实。大都六脉俱数。经曰。微者为虚。弱者为虚。细者气血俱虚。盖心
主血。肝藏血。乃血虚无疑。肾藏精属水。其部见微。乃为水不足。水既不足。相火妄行无
制。以致此疾。经曰。诸痛疮痒。皆属心火。右手寸脉实。实者阳也。脉经曰。诸阳为热。
乃热在肺分。火克金故也。且肺主皮毛。皮毛之疾。肺气主之。胸膈及皮毛之疾。为至高之
疾也。右关微实。乃火在土分。土得火则燥。肌肉之间。脾气主之。肌肉及皮毛痛痒。皆火
热在上明矣。右尺微实。火居火位。两火合明。阳多阴少。治宜补水以制火。养金以伐木。

而吐之。如是者三。而痒释矣。

震按河间谓痒为美疾。以其搔爬有趣。且与身命无伤也。然亦有屡治不效者。以不得病
因。而漫以凉血祛风为治耳。今观倪江薛三案见解。用药俱精细周到。可见。昔贤虽遇轻证
亦不肯忽略。
倪仲贤治疗吴陵盛架阁的妻子。她的左右肩背上下部位出现瘙痒，甚至蔓延至双臂、头部和面部。多次用艾条灸烤瘙痒部位，暂时停止后又复发。这样持续了几年。老人诊察她的脉象说：左关脉浮而盛大，右口（应为“寸”）脉沉实。这是由饮酒和食用肥甘厚味引起的。于是给予清热、化食、行滞的药剂，瘙痒随即停止。
江汝洁治疗一位妇人。她的上身直至头面全部瘙痒，伴有刺痛并起块。众位医生都认为是大风病等证候。江汝洁诊得左手三部脉均细，右手三部脉皆微实。大致六部脉都数。《内经》说：微脉属于虚证，弱脉属于虚证，细脉表示气血俱虚。心主血，肝藏血，这显然是血虚无疑。肾藏精属水，其脉位见微脉，说明肾水不足。水既已不足，相火就会妄行而无制约，从而导致此病。《内经》说：各种疼痛疮疡瘙痒，都属于心火。右手寸脉实，实脉代表阳盛。《脉经》说：诸阳脉主热，这说明热邪在肺分，因为火克金。况且肺主皮毛，皮毛的疾病由肺气主管。胸膈及皮毛的疾病，属于高位的疾病。右关脉微实，说明火在土分。土得到火则燥，肌肉之间由脾气主管。肌肉及皮毛的痛痒，都是火热在上部的明证。右尺脉微实，火居火位，两火合明，阳气多阴气少。治疗应当补水以制火，养金以伐木。如果当作风邪来治，未免是以火救火，以燥助燥。于是使用生地、白芍各一钱，人参、[原文缺字，推测为黄芪或党参]各六分，连翘、丹皮各六分，麦冬八分，黄柏、防风、甘草各四分，五味子九粒。水煎温服。药渣中加入苦参一两，再煎煮后外洗。服用十数剂后痊愈。
薛立斋治疗一名十二岁的女子。她容易发怒，全身瘙痒。使用柴胡、川芎、山栀、芍药来清肝火；使用生地、当归、黄芩来凉肝血；使用白术、茯苓、甘草来健脾土，从而治愈。半年后，全身出现赤痕，有时眩晕。这是肝火炽盛，血液受热而妄行。当天晚上果然月经来潮。
意庵治疗一人。因为在田间收割稻谷，忽然全身瘙痒深入骨髓。使用食盐九钱，泡在汤中三碗。每喝一碗，探喉催吐。像这样进行三次，瘙痒就解除了。
俞震按语：刘河间认为瘙痒是轻微的疾病，因为搔抓有趣，且对身体性命没有伤害。然而也有屡治不效的情况，是因为没有找到病因，随意采用凉血祛风的方法治疗。现在看倪、江、薛三位医生的医案，见解独到，用药精细周到。由此可见，先贤即使遇到轻症也不肯忽略。
Ni Zhongxian treated the wife of Sheng Jiage from Wuling. She suffered from itching on her left and right shoulders, back, upper and lower body, which extended to both arms, head, and face. Repeated moxibustion on the itchy areas provided only temporary relief before the symptoms recurred. This persisted for several years. The physician palpated her pulse and stated: "The left Guan position is floating and vigorous, while the right Cun position (note: original text says 'Kou', likely a typo for 'Cun') is deep and solid. This is caused by alcohol consumption and rich food intake." He administered a formula to clear heat, resolve food stagnation, and promote qi circulation, after which the itching ceased.
Jiang Rujie treated a woman whose upper body, extending to the head and face, was itchy, accompanied by stinging pain and raised plaques. Other physicians diagnosed this as Big Wind disease or similar conditions. Jiang palpated the pulse and found all three positions on the left hand to be fine (Xi), while all three positions on the right hand were slightly solid (Shi). Generally, all six pulse positions were rapid (Shu). The Classic states: "A fine pulse indicates deficiency; a weak pulse indicates deficiency; a fine pulse signifies deficiency of both Qi and Blood." Since the Heart governs Blood and the Liver stores Blood, this is undoubtedly Blood deficiency. The Kidney stores Essence and belongs to Water; the appearance of a fine pulse in its position indicates insufficient Kidney Water. With insufficient Water, Ministerial Fire flares up without restraint, leading to this disease. The Classic states: "All pain, sores, and itching belong to Heart Fire." The right Cun position is solid, indicating Yang excess. The Pulse Classic states: "All Yang pulses indicate Heat." Thus, Heat resides in the Lung sector, as Fire overacts on Metal. Furthermore, the Lung governs the skin and hair, so diseases of the skin and hair are under the jurisdiction of Lung Qi. Diseases of the chest, diaphragm, and skin are considered high-level diseases. The right Guan position is slightly solid, indicating Fire in the Earth sector. When Earth receives Fire, it becomes dry; the Spleen Qi governs the muscles. Therefore, pain and itching in the muscles and skin clearly indicate Heat and Fire located above. The right Chi position is slightly solid, with Fire occupying the Fire position. Two Fires combine to illuminate, resulting in excessive Yang and deficient Yin. The treatment should involve nourishing Water to control Fire and nourishing Metal to subdue Wood. Treating it as Wind pathogen would be akin to adding fire to fire and dryness to dryness. The prescription consisted of Sheng Di Huang (Rehmanniae Radix) and Bai Shao (Paeoniae Radix Alba), each 1 qian; Ren Shen (Ginseng Radix et Rhizoma) and [missing character, likely Huang Qi or Dang Shen], each 6 fen; Lian Qiao (Forsythiae Fructus) and Dan Pi (Moutan Cortex), each 6 fen; Mai Dong (Ophiopogonis Tuber), 8 fen; Huang Bo (Phellodendri Cortex), Fang Feng (Saposhnikoviae Radix), and Gan Cao (Glycyrrhizae Radix et Rhizoma), each 4 fen; Wu Wei Zi (Schisandrae Fructus), 9 grains. Decocted in water and taken warm. The dregs were mixed with Ku Shen (Sophorae Flavescentis Radix), 1 liang, decocted again, and used for external washing. After more than ten doses, the patient recovered.
Xue Lizhai treated a twelve-year-old girl who was prone to anger and suffered from generalized itching. He used Chai Hu (Bupleuri Radix), Chuan Xiong (Ligustici Chuanxiong Rhizoma), Shan Zhi (Gardeniae Fructus), and Shao Yao (Paeoniae Radix) to clear Liver Fire; Sheng Di Huang (Rehmanniae Radix), Dang Gui (Angelicae Sinensis Radix), and Huang Qin (Scutellariae Radix) to cool Liver Blood; and Bai Zhu (Atractylodis Macrocephalae Rhizoma), Fu Ling (Poria), and Gan Cao (Glycyrrhizae Radix et Rhizoma) to strengthen Spleen Earth, resulting in a cure. Half a year later, red marks appeared all over her body, and she experienced occasional dizziness. This indicated intense Liver Fire causing Blood to move recklessly due to heat. That night, her menstruation indeed commenced.
Yi An treated a man who, while harvesting rice in the fields, suddenly developed severe itching that felt as if it penetrated to the bone marrow. He prescribed 9 qian of edible salt dissolved in three bowls of hot water. The patient drank one bowl at a time and induced vomiting by stimulating the throat. This process was repeated three times, after which the itching resolved.
A child suffering from generalized itching was treated by applying mashed fresh ginger wrapped in cloth to the skin, which stopped the itching.
Yu Zhen commented: Liu Hejian considered itching a mild ailment because scratching provides pleasure and does not endanger life. However, there are cases where treatment fails repeatedly because the cause is not identified, and cooling blood and dispelling wind are applied indiscriminately. Observing the cases of Ni, Jiang, and Xue, their insights were unique, and their prescriptions were precise and comprehensive. This demonstrates that ancient sages did not neglect even mild conditions.
