乐疽生于肩前及腋上部位，具体在骨缝开合处的凹陷中。其质地坚硬如同鹅卵，疼痛深入骨髓，这是由于心包络血热与气机郁结所致。
【注】此证发生在肩前腋上的位置，即骨缝开合的空陷处。初起时像花椒子一样小，逐渐肿胀变硬，大小如鹅卵，按压时疼痛直达骨骼。此病归属于心包络经，由血热和气郁形成。病情到了期限会溃破，流出稠厚的脓液，肿胀消退的为顺证；若月余不溃破，或者已经溃破却流出清水，且肿胀坚硬不退的，为逆证。初期适宜服用神授卫生汤，如果恶风症状特别严重，加倍加入葱白以发汗解表，随后服用托里透脓汤；若溃破迟缓，则服用十全大补汤。溃破后的内外治疗方法，均参照痈疽溃疡门的记载。
（附：藕包毒）
痈生在肩肘周围，全面肿胀，颜色发红，伴有粟粒状突起和僵硬感。藕包毒的形状像鸭或鹅的蛋，发病部位涉及手三阴经和手三阳经。
【注】此证由风瘟或风火凝结而成。生于肩下肘上，四周弥漫性肿胀，颜色发红且疼痛。初起时状如一簇粟米，也有起一个僵硬的疙瘩的，逐渐肿胀、发红、发热，化脓后疼痛剧烈。红肿之外没有晕圈的为顺证，有两条晕圈的属险证，有三四条晕圈的为逆证。肿胀发于内侧或外侧，结肿一枚，形状像桃子或鸭、鹅蛋的，名叫藕包毒。所谓毒，是指较轻的痈证。痈和藕包毒的内外治疗方法，均参照痈疽肿疡、溃疡门的记载。此痈毒发作的部位，如果在内侧，属于手三阴经；在外侧，属于手三阳经。根据证候使用引经药物，必然获得疗效。
Leju (Shoulder Carbuncle) arises in the anterior shoulder and above the axilla, specifically within the depression of the bone fissure where opening and closing occur. It is hard like a goose egg, with pain penetrating into the bone, caused by blood heat and qi stagnation in the Pericardium Meridian (Xinbao Jing).
[Note] This condition occurs anterior to the shoulder and above the axilla, in the hollow of the bone fissure. Initially, it resembles a peppercorn, gradually swelling and hardening to the size of a goose egg. Palpation causes pain that penetrates to the bone. This disease belongs to the Pericardium Meridian and is formed by blood heat and qi stagnation. When the condition reaches its term, it will ulcerate and discharge thick pus; if the swelling subsides, it is a favorable prognosis (Shun). If it does not ulcerate after more than a month, or if it ulcerates but discharges clear water while the swelling and hardness persist, it is an unfavorable prognosis (Ni). Initially, Shen Shou Wei Sheng Tang is suitable. If aversion to wind is excessive, add extra Cong Bai (Scallion Stem) to induce sweating, followed by Tuo Li Tou Nong Tang. If ulceration is delayed, Shi Quan Da Bu Tang is used. The internal and external treatment methods after ulceration follow the records in the Ulcerative Stage of Carbuncles and Sores section.
(The area from the shoulder to the elbow is called "Nao".)
(Attachment: Ou Bao Du / Lotus Root Bag Poison)
Yong (Carbuncle) appears around the shoulder and elbow with circumferential swelling, redness, millet-like papules, and stiffness. Ou Bao Du presents as a swelling resembling a duck or goose egg, involving the Hand Three Yin and Hand Three Yang meridians.
[Note] This condition is caused by the conglomeration of wind-warmth or wind-fire. It arises below the shoulder and above the elbow, with diffuse circumferential swelling, redness, and pain. Initially, it resembles a cluster of millet grains, or sometimes a single stiff nodule. It gradually becomes swollen, red, hot, and extremely painful upon suppuration. If there is no halo outside the redness and swelling, it is a favorable prognosis; two halos indicate a dangerous condition; three or four halos indicate an unfavorable prognosis. A solitary swelling arising on either the medial or lateral side, shaped like a peach or a duck/goose egg, is named Ou Bao Du. "Du" refers to a mild form of carbuncle. The internal and external treatments for Yong and Ou Bao Du follow the records in the Swollen Stage and Ulcerative Stage of Carbuncles and Sores sections. Regarding the location of this carbuncle toxin's onset: if it is on the medial side, it belongs to the Hand Three Yin Meridians; if on the lateral side, it belongs to the Hand Three Yang Meridians. Using guiding herbs according to the syndrome will surely yield effective results.
