【方歌】臂痈臂疽绕臂生，平紫硬疽红肿痈，荣卫风邪逆肉理，
甚则拳缩彻骨疼。
【注】此证生臂外侧，属三阳经；臂里侧，属三阴经。高肿红
活，焮痛溃速者为痈；平陷紫暗，坚硬木痛，溃迟者为
疽。俱由荣卫不周，感受风邪，逆于肉理而成。初起形
如粟粒，憎寒壮热，宜服荆防败毒散汗之；焮痛烦热，
宜服白芷升麻汤消之；脓势将成，宜服托里透脓汤，脓
热针之。若疽证木痛，无红无热，此属气血两虚，无论
已溃、未溃，宜服十全大补汤托之。溃后，内外治法俱
按痈疽肿疡、溃疡门。若拳缩筋不能舒，疼痛彻骨者，
系溃深伤脉也，属逆。

【方歌】腕痈三阳风火凝，手腕背面结痈形，高肿速溃顺易治，
腐烂露骨逆难功。
【注】此证生于手腕背面，属手三阳经，由风火凝结而成。高
肿红活，在十四日溃破脓出痛减者，顺而易治；手腕乃
皮肉浇薄之处，若迁延日久不溃，或漫肿平塌，既溃腐
烂露骨者逆，难于收功。初服荆防败毒散汗之，外用太
乙紫金锭敷之。脓成将溃，即按痈疽肿疡、溃疡门治法
。

【方歌】臂痈和臂疽生长在手臂周围，平陷紫暗坚硬疼痛的是疽，红肿热痛的是痈。这是由于营卫之气与风邪逆行于肌肉纹理之间，严重时会导致手指蜷缩如拳，疼痛直达骨骼。
【注】此证生于手臂外侧，归属于三阳经；生于手臂内侧，归属于三阴经。肿势高起、颜色红活、焮热疼痛且溃破迅速的是痈；肿势平陷、颜色紫暗、质地坚硬且麻木疼痛、溃破缓慢的是疽。这两种病症均因营卫之气运行不周，感受风邪，邪气逆乱于肌肉纹理所致。初起时形状像粟米粒一样，伴有怕冷和高热，适宜服用荆防败毒散通过发汗来治疗；若出现焮热疼痛、烦躁发热，适宜服用白芷升麻汤以消散之；若脓势即将形成，适宜服用托里透脓汤，待脓成后用针穿刺排脓。如果是疽证，表现为麻木疼痛，无红肿也无发热，这属于气血两虚，无论已经溃破还是未溃破，都适宜服用十全大补汤以托毒外出。溃破之后，内服和外治的方法均按照痈疽肿疡门、溃疡门中的方法处理。如果出现手指蜷缩不能伸展，疼痛直达骨骼的情况，这是因为溃烂过深损伤了血脉，属于逆证（预后不良）。

【方歌】腕痈由三阳经的风火凝结而成，在手背手腕处结成痈形。肿势高起且迅速溃破为顺证，容易治疗；若腐烂露出骨头则为逆证，难以治愈。
【注】此证生于手腕背面，归属于手三阳经，由风火邪气凝结而成。肿势高起、颜色红活，在十四天内溃破流脓且疼痛减轻的，属于顺证，容易治疗；手腕部位是皮肉浅薄之处，如果拖延日久不溃破，或者漫肿平塌，一旦溃破后腐烂露出骨头的，属于逆证，难以收功愈合。初期服用荆防败毒散通过发汗治疗，外用太乙紫金锭敷贴。脓成即将溃破时，即按照痈疽肿疡门、溃疡门中的方法治疗。
[Verse] Bi Yong (Carbuncle of the Arm) and Bi Ju (Gangrene of the Arm) arise around the arm. Ping Zi Ying Ju (flat, purple, hard, and painful lesions) are Ju; Hong Zhong Yong (red, swollen, hot, and painful lesions) are Yong. This is caused by Ying Wei (Nutritive and Defensive Qi) and Wind Evil reversing within the muscle tissue. In severe cases, it leads to fist-like contraction and pain penetrating to the bone.
[Note] This condition occurring on the lateral side of the arm belongs to the Three Yang Meridians; that on the medial side belongs to the Three Yin Meridians. Lesions that are high-swollen, red, vibrant, with intense heat and pain, and rupture quickly are Yong (Carbuncle); those that are flat-depressed, purple-dark, hard, numb, and painful, with slow rupture are Ju (Gangrene). Both result from the uneven circulation of Ying Wei (Nutritive and Defensive Qi), contracting Wind Evil, which reverses in the muscle tissue. Initially, the shape resembles a millet grain, accompanied by aversion to cold and high fever; it is appropriate to administer Jing Fang Bai Du San (Schizonepeta and Saposhnikovia Decoction to Overcome Toxins) to induce sweating. If there is intense heat, pain, irritability, and fever, it is appropriate to administer Bai Zhi Sheng Ma Tang (Angelica Dahurica and Cimicifuga Decoction) to dissipate the swelling. When pus is about to form, it is appropriate to administer Tuo Li Tou Nong Tang (Decoction to Support the Interior and Penetrate Pus), and puncture with a needle when pus matures. If it is a Ju syndrome characterized by numbness and pain without redness or heat, this belongs to deficiency of both Qi and Blood. Regardless of whether it has ruptured or not, it is appropriate to administer Shi Quan Da Bu Tang (Decoction for Ten Complete Tonifications) to support the interior and expel toxins. After rupture, internal and external treatment methods follow those in the "Yong Ju Swelling Ulcer" and "Ulcerated Ulcer" sections. If the hand contracts into a fist and cannot extend, with pain penetrating to the bone, this indicates deep ulceration damaging the vessels, which is considered a Ni (Adverse/Intractable) prognosis.

[Verse] Wan Yong (Carbuncle of the Wrist) is formed by the condensation of Wind and Fire in the Three Yang Meridians, presenting as a carbuncle on the dorsal aspect of the wrist. High swelling with rapid rupture is a Shun (Favorable) pattern, easy to treat; rotting with exposed bone is a Ni (Adverse) pattern, difficult to cure.
[Note] This condition arises on the dorsal aspect of the wrist, belonging to the Hand Three Yang Meridians, formed by the condensation of Wind and Fire. High swelling, redness, and vitality, with rupture and pus discharge leading to pain reduction within fourteen days, constitute a Shun (Favorable) pattern, which is easy to treat. The wrist is an area where skin and flesh are thin. If the condition lingers for a long time without rupturing, or presents with diffuse swelling and flat collapse, and after rupture involves rotting with exposed bone, it is a Ni (Adverse) pattern, difficult to heal. Initially, administer Jing Fang Bai Du San (Schizonepeta and Saposhnikovia Decoction to Overcome Toxins) to induce sweating, and apply Tai Yi Zi Jin Ding (Taiyi Purple Gold Pill) externally. When pus matures and is about to rupture, treat according to the methods in the "Yong Ju Swelling Ulcer" and "Ulcerated Ulcer" sections.
