湿热郁于皮肤，久而不散，发而为斑，黑白相杂，遍身花藻，甚者变而为紫白癜风，虽
无疾痛害事，不可以不防微而杜渐也。
防风通圣散 治汗斑内外挟热。（方见风门。）
玄参升麻汤 治同。（方见斑丹门。）
一方∶用白茄切段，蘸硫黄、白附子擦之，三次愈。初次变黑，二次、三次则白而愈。
一方∶用生姜片蘸信末、陀僧二味擦之良久，小便洗过，用清水洗之，三次愈。
经曰∶真心痛者，寒邪伤其君也，手足青至节，甚则旦发夕死，夕发旦死。厥心痛者，
乃寒邪客于心胞络也。
举痛论云∶寒气客于背俞之脉，则血脉泣，脉泣则血虚，血虚则痛，其俞注于心，故相引
而痛。按之则热气至，则痛止矣。重感于寒则痛久矣。
《针经》曰∶足太阴之脉，其支者复从胃别上膈注心中。是动则病舌根强，食则呕，胃脘痛，
腹胀，善噫，心中急痛。胃病者，腹 胀，胃脘当心而痛，上支两胁，膈咽不通。
《脉经》曰∶忧愁思虑则伤心，则苦惊喜忘善怒。心伤者，其人劳倦则头面赤而下重，
心中痛彻背，其脉弦，此心脏伤所致也。
《病机机要》曰∶诸心痛者，皆少阴厥阴气上冲也。有热厥心痛者，身热足寒，痛甚则
烦躁而吐，额自汗出，
知为热也。其脉浮大而洪，当灸太溪及昆仑，谓表里俱泻之，是谓热病汗不出，引热下利，表
汗通身而出者愈也。灸毕服金铃子散则愈，痛止服枳术丸去其余邪也。有火实心中痛者，因气
而食，卒然发痛，大便或秘，久则注闷，心胸高起，按之愈。痛不能饮食，急可利之，利后以
本汤去其余邪也。有寒厥心痛者，手足逆而通身冷汗出，便溺清利，或大便利而不渴，气微力弱，
急以术附汤温之。寒厥暴痛非久病也，旦发夕死，急当救之。是知久病无热，暴病非寒也。此寒
热厥痛，与夫大实心痛者治法已详。又有久病气血虚损及素作劳羸弱之人患心痛者，皆虚痛也。故
钱氏心虚者炒盐补之，《图经》《衍义》中牡蛎治心痛，则蛎粉与盐实得之矣。
湿热之邪郁结于皮肤，日久不散，发作时形成斑疹，黑白相间，遍布全身如花纹藻饰。严重者演变为紫白癜风，虽然不会造成剧烈的疼痛或危害生命，但不可不防微杜渐，提前预防。
防风通圣散：治疗汗斑兼有内热和外热的情况。（该方剂详见“风门”章节。）
玄参升麻汤：治疗同上。（该方剂详见“斑丹门”章节。）
另一偏方：用白茄子切成段，蘸取硫黄粉和白附子粉末擦拭患处，三次即可痊愈。初次擦拭后颜色变黑，第二次、第三次擦拭后则变白而痊愈。
另一偏方：用生姜片蘸取信石末和陀僧（红铅/铅霜类矿物药）两种药物粉末，长时间擦拭患处，随后用小便清洗，再用清水洗净，三次即可痊愈。
经典医籍记载：真心痛，是寒邪损伤了心之君主（心脏本体），症状表现为手足青紫直至关节，病情严重者可出现早晨发病傍晚死亡，或傍晚发病早晨死亡的情况。厥心痛，则是寒邪客居于心包络所致。
《素问·举痛论》云：寒气侵袭背部俞穴所属的经脉，导致血脉凝涩不通；血脉凝涩则血虚，血虚则产生疼痛；背部的俞气注连于心，所以互相牵引而疼痛。按压患处可使热气到达，疼痛就会停止。如果再次感受寒邪，疼痛就会持久不愈。
《灵枢·经脉》曰：足太阴脾经的支脉，从胃部别出，上行穿过膈肌注入心中。这条经脉发生病变时，会出现舌根僵硬，进食后呕吐，胃脘疼痛，腹胀，容易嗳气，心中紧迫疼痛等症状。胃病本身的表现包括：腹胀，胃脘部当心窝处疼痛，疼痛向上牵引至两侧胁肋，胸膈和咽喉部位不通畅。
《脉经》曰：忧愁思虑会损伤心脏，导致患者出现惊恐、健忘、易怒等症状。心脏受损的人，在劳累疲倦时会头面发红且下肢沉重，心中疼痛放射至背部，脉象呈弦象，这是心脏受伤所导致的。
《卫生宝鉴·病机机要》曰：各种心痛，都是少阴经和厥阴经的气机上冲所致。其中有热厥心痛，表现为身体发热而脚底发凉，疼痛剧烈时烦躁并伴有呕吐，额头自汗出，由此可知属于热证。其脉象浮大且洪大，应当艾灸太溪穴和昆仑穴，这叫做表里双泻的方法。如果是热病导致汗不出，通过引热下行通便，使全身通透出汗即可痊愈。艾灸完毕后服用金铃子散以治愈，疼痛停止后服用枳术丸以清除余邪。有火实型心中痛者，因气滞和饮食积滞突然发作疼痛，大便可能秘结，时间久了感到闷胀，心胸部位高起，按压后疼痛缓解但不能进食，急需通利大便，通便后服用本方汤剂以清除余邪。有寒厥心痛者，手足逆冷且全身冷汗出，大小便清长通畅，或者大便稀溏且不口渴，气息微弱体力虚弱，急需使用术附汤温阳散寒。寒厥引起的暴发性疼痛并非久病，若早晨发病傍晚即死，必须紧急救治。由此可知，久病通常无热象，突发急病多非寒邪所致。以上详细论述了寒热厥痛以及大实心痛的治疗方法。又有久病导致气血虚损，以及平时过度劳累、体质羸弱之人患有的心痛，都属于虚痛。因此钱乙主张心虚者用炒盐来补益，《本草图经》和《本草衍义》中记载牡蛎治疗心痛，说明牡蛎粉与盐确实符合这一治疗原理。
Damp-heat (Shi Re) stagnates in the skin, lingering for a long time without dissipating, manifesting as macules that are mixed black and white, covering the body like floral patterns. In severe cases, it transforms into purple and white wind-macules (Zi Bai Feng Ban). Although it causes no severe pain or life-threatening harm, one must not fail to nip it in the bud and prevent its progression.
Fangfeng Tongsheng San (Saposhnikia Universal Relief Powder): Treats sweat-spots with both internal and external heat. (See formula under "Wind Gate".)
Xuanshen Shengma Tang (Scrophulariae and Cimicifugae Decoction): Treats the same condition. (See formula under "Macule and Dan Gate".)
Another prescription: Cut white eggplants into segments, dip them in sulfur powder (Liu Huang) and Fuzi powder (Bai Fuzi), and rub the affected area. It heals after three applications. The first application turns the spots black; the second and third turn them white and heal them.
Another prescription: Rub ginger slices dipped in arsenic trioxide powder (Xin Mo) and lead oxide powder (Tuo Seng) onto the area for a long time. Wash with urine, then wash with clear water. It heals after three applications.
The Classics state: True Heart Pain (Zhen Xin Tong) occurs when cold pathogen (Han Xie) injures the Monarch of the Heart. Symptoms include cyanosis of hands and feet extending to the joints. In severe cases, death may occur from morning to evening or from evening to morning. Jue Heart Pain (Jue Xin Tong) occurs when cold pathogen lodges in the Pericardium Collateral (Xin Bao Luo).
The *Suwen: Ju Tong Lun* states: When cold qi invades the back-Shu vessels, blood vessels become stagnant. Stagnation leads to blood deficiency, and deficiency leads to pain. Since the Shu points connect to the heart, the pain radiates and pulls. Pressing the area brings warmth, stopping the pain. If exposed to cold again, the pain becomes chronic.
The *Ling Shu* states: The branch of the Foot-Taiyin Spleen Meridian separates from the stomach, ascends through the diaphragm, and enters the heart. When this meridian is disturbed, symptoms include a stiff tongue root, vomiting after eating, epigastric pain, abdominal distension, frequent belching, and urgent pain in the heart region. Stomach disease manifests as abdominal distension, epigastric pain centered at the xiphoid process, radiation to the hypochondrium, and obstruction of the chest, diaphragm, and throat.
The *Mai Jing* states: Worry and overthinking injure the Heart, leading to fright, surprise, forgetfulness, and irritability. A person with injured Heart Qi feels fatigue, redness of the face and head, heaviness of the lower body, and penetrating heart pain radiating to the back. The pulse is wiry (Xian). This is caused by Heart injury.
The *Bing Ji Yao Yao* states: All types of heart pain are due to the counter-flow of Qi from the Shaoyin and Jueyin meridians. There is Heat-Jue Heart Pain, characterized by body heat but cold feet. Severe pain causes irritability and vomiting, with spontaneous sweating on the forehead, indicating a Heat syndrome. The pulse is floating, large, and surging. Moxibustion should be applied to Taixi (KI3) and Kunlun (BL60), representing simultaneous draining of exterior and interior. For heat diseases where sweat does not emerge, guiding heat downward via bowel movement allows general sweating, leading to recovery. After moxibustion, Jinlingzi San (Corydalis and Chaenomelis Powder) is taken to cure. After pain stops, Zhizhu Wan (Immature Bitter Orange and Atractylodes Pill) is taken to eliminate residual pathogens. There is Fire-Excess Heart Pain, caused by Qi stagnation and food retention, causing sudden pain. Stool may be constipated. Prolonged stagnation causes fullness and bulging of the chest and heart region, relieved by pressure but preventing eating. Urgent purgation is required, followed by the main decoction to clear residual pathogens. There is Cold-Jue Heart Pain, characterized by cold extremities, cold sweat all over the body, clear and profuse urination and defecation, or loose stools without thirst, with weak breath and energy. Shuzhifu Tang (Atractylodes and Aconite Decoction) should be used urgently to warm and dispel cold. Acute Cold-Jue pain is not a chronic illness; if it strikes in the morning and kills by evening, emergency rescue is needed. Thus, chronic illnesses usually lack heat signs, while acute illnesses are rarely due to cold. The treatments for Cold-Heat Jue pain and Great Excess Heart Pain have been detailed above. Additionally, heart pain suffered by those with chronic Qi and Blood deficiency, or by those who are chronically overworked and emaciated, belongs to Deficiency Pain. Therefore, Qian Yi advocated using roasted salt to tonify Heart deficiency. *Bencao Tujing* and *Bencao Yanyi* record Oyster Shell (Muli) treating heart pain, confirming that oyster shell powder and salt are appropriate.
