【方歌】病〔虾〕（一种生于手背的痈疽，因其形状似虾而得名）多发生于手背，其形态如同虾状，表现为局部红肿疼痛。内治宜服用具有清热解毒功效的药物，外治宜用汤剂清洗患处，此病由手三阳经的热毒积聚而成。
【注】此证候生于手背，属于手三阳经积热毒盛所致。其形态像虾，有隆起的硬结，局部红肿胀痛。初期适宜服用黄连消毒饮（Huanglian Xiaodu Yin, Coptis Decoction for Disinfecting Toxins），外用食盐、酒糟、香油一同炒至散发香味，然后用滚开的热水浸泡淬取药液，淋洗患处即可消退。如果隆起的硬结不消散，再使用蟾酥饼（Chansu Bing, Toad Venom Cake）贴敷，外用巴膏（Bagao, Ba Paste）覆盖，以使坏死组织排尽并消除硬结，随后敷上生肌散（Shengji San, Tissue-Regenerating Powder），仍用膏药覆盖以促进伤口收敛愈合。
方剂：黄连消毒饮（参见头部百会疽章节）
蟾酥饼（即蟾酥丸制成饼状。参见疔疮门章节）
巴膏、生肌散（均参见溃疡门章节）
【方歌】手丫发（生于手指缝间的痈疽）发生在手指歧骨之间的缝隙中，其病因源于脾经湿火凝结。初起时如粟米大小，逐渐增大如豆粒，伴有灼热疼痛。内外治疗方法参照疔证（Ding Syndrome, Carbuncle/Boil）的门类进行诊治。
【注】此证候生于手指歧骨之间的缝隙中，除了大拇指合谷穴附近的情况外，其余手指缝间发生的患部，即称为手丫发。其病本于脾经湿火凝结而成。初起时颜色发红，大小如粟米，逐渐增大如豆粒，局部灼热疼痛。溃破后若疼痛不止，需等待脓液堵塞物脱出，疼痛才会停止。内外治疗方法均参照疔证门类。
【方歌】调疽（生于拇指的痈疽）由肺经积热而生，初起如粟米，渐肿如李子，呈青紫色且疼痛。若在第六天刺破排出脓血为吉兆，若出现黑色腐烂蔓延则预示断指之凶险。
【注】此证候生于手大拇指，由肺经积热所致。初起如粟豆大小，逐渐肿胀如李子，呈现青紫色，伴有麻木感，痒痛彻心。若在第六天刺破，流出稠脓和鲜血者为吉兆，流出黑血者情况危险。初期服用麦灵丹（Mailing Dan, Mailing Pill）以发汗解表，随后服用仙方活命饮（Xianfang Huoming Yin, Immortal Formula for Saving Lives），外敷白锭子（Baidingzi, White Stick Paste）。其余内外治疗方法，均同痈疽肿疡（Zhongyang, Swelling and Ulceration）、溃疡门类别。如果出现黑色腐烂蔓延且不疼痛的情况，称为“断指”，属于逆证（Ni Zheng, Adverse Prognosis）。治疗方法与足部脱疽（Tuoju, Gangrene of the Foot）相同。
方剂：麦灵丹、仙方活命饮、白锭子（均参见肿疡门章节）
[Formula Song] The condition known as "Bing Xia" (a carbuncle occurring on the back of the hand, named for its resemblance to a shrimp) typically arises on the dorsum of the hand. Its morphology resembles a shrimp, characterized by local redness, swelling, and pain. Internal treatment should employ drugs with heat-clearing and detoxifying properties, while external treatment involves washing the affected area with decoctions. This disease is caused by the accumulation of heat-toxin in the three Yang meridians of the hand.
[Annotation] This syndrome occurs on the dorsum of the hand and is caused by the accumulation of excessive heat-toxin in the three Yang meridians of the hand. Its shape resembles a shrimp, featuring elevated indurations with local redness, swelling, and pain. In the initial stage, it is appropriate to take Huanglian Xiaodu Yin (Coptis Decoction for Disinfecting Toxins). Externally, salt, wine lees, and sesame oil are stir-fried together until fragrant, then steeped in boiling water to extract the liquid, which is poured over the affected area for washing; this can lead to resolution. If the elevated induration does not subside, Chansu Bing (Toad Venom Cake) should be applied topically, covered with Bagao (Ba Paste), to facilitate the discharge of necrotic tissue and elimination of the induration. Subsequently, Shengji San (Tissue-Regenerating Powder) should be applied, still covered with paste to promote wound contraction and healing.
Formulas: Huanglian Xiaodu Yin (See section on Baihui Ju); Chansu Bing (Toad Venom Pills made into cakes; See section on Ding Chuang); Bagao and Shengji San (Both see section on Kuiyang).
[Formula Song] Shouya Fa (Carbuncle arising in the interdigital spaces) occurs in the gaps between the metacarpal bones. Its etiology stems from the condensation of damp-fire in the Spleen Meridian. Initially appearing like millet grains, it gradually enlarges to the size of beans, accompanied by burning heat and pain. Both internal and external treatments follow the protocols for Ding Syndrome (Carbuncle/Boil).
[Annotation] This syndrome arises in the interdigital spaces between the metacarpal bones. Except for cases involving the Hegu acupoint near the thumb, any lesion occurring in the other interdigital spaces is termed Shouya Fa. It originates from the condensation of damp-fire in the Spleen Meridian. Initially, it appears red and small like millet, gradually enlarging to the size of a bean, with local burning heat and pain. If pain persists after ulceration, one must wait for the purulent plug to discharge before the pain ceases. Both internal and external treatments adhere to the protocols outlined in the Ding Syndrome section.
[Formula Song] Diao Ju (A carbuncle on the thumb) arises from accumulated heat in the Lung Meridian. Initially resembling millet, it swells to the size of a plum, presenting with cyanosis and pain. Puncture on the sixth day yielding pus and fresh blood indicates a favorable prognosis; blackening and spreading necrosis portends the ominous sign of finger amputation.
[Annotation] This syndrome occurs on the thumb and is caused by accumulated heat in the Lung Meridian. Initially, it is small like millet or beans, gradually swelling to the size of a plum, presenting with cyanosis, numbness, and intense itching and pain penetrating to the heart. If punctured on the sixth day, the discharge of thick pus and fresh blood is auspicious, whereas the discharge of black blood indicates danger. Initially, Mailing Dan (Mailing Pill) is administered to induce sweating, followed by Xianfang Huoming Yin (Immortal Formula for Saving Lives), with Baidingzi (White Stick Paste) applied externally. All other internal and external treatments follow those for Zhongyang (Swelling and Ulceration) and Kuiyang sections. If black necrosis spreads without pain, it is termed "Duan Zhi" (Finger Amputation/Gangrene), which is classified as Ni Zheng (Adverse Prognosis). The treatment method is identical to that for Tuoju (Gangrene of the Foot).
Formulas: Mailing Dan, Xianfang Huoming Yin, Baidingzi (All see section on Zhongyang).
