【方歌】甘疽忧思气结成，膺生谷粒紫萎形，寒热硬痛宜速溃，
溃迟须防毒陷攻。
【注】此证由忧思气结而成。生于膺上，即胸膛两旁肉高处，
属肺经中府穴之下，无论左、右皆能为患。初如谷粒色
青，渐若栝蒌色紫，坚硬疼痛，憎寒壮热，速溃稠脓者
顺；若过十日寒热不退，信脓不生，脉见浮数，防毒内
陷攻里，致生恶证属逆。初宜服荆防败毒散，以疏解寒
热，次服内托黄耆散。应期不溃者，急服十全大补汤托
之。其余内外治法，按痈疽肿疡、溃疡门。
方剂：荆防败毒散（见项部脑疽）
内托黄耆散（见背部中搭手）
十全大补汤（见溃疡门）
【方歌】膻中疽起粟粒形，色紫坚硬渐焮疼，七情火毒发任脉，
急随证治缓成凶。
【注】此证生于心窝之上，两乳中央，属任脉经膻中穴。由脏
腑不和，七情不平，火毒凝结而成。初起如粟，色紫坚
硬，渐生焮热肿痛，憎寒壮热，宜急服仙方活命饮加苏
叶薄荷叶汗之。或烦躁作呕，唇焦大渴，宜夺命丹清之
，俟表证已退，急服托里透脓汤；若疮势不起属虚，宜
十全大补汤托之。但脓中为气海气之所居焉，施治贵早
，若迟则毒陷攻里，伤膜透气者逆。其余内外治法，俱
按痈疽肿疡、溃疡门。

【方歌】甘疽由忧思导致气机郁结而成，生于胸前，形状如谷粒且呈紫色萎缩状，伴有寒热、硬痛，应当迅速使其溃破；若溃破延迟，必须防止毒邪内陷攻里。
【注】此证是由于忧思导致气机郁结而形成的。生于胸前（即胸膛两侧肌肉隆起处），位于肺经中府穴下方，无论左侧还是右侧都可能发病。初起时像谷粒一样青色，逐渐变为栝蒌色紫，坚硬疼痛，伴有憎恶寒冷和壮热，若能迅速溃破并流出稠脓为顺证；如果超过十天寒热不退，排不出脓液，脉象浮数，需防止毒邪内陷攻里，从而产生恶证，这属于逆证。初期适宜服用荆防败毒散，以疏解寒热；随后服用内托黄耆散。到了应期仍未溃破的，紧急服用十全大补汤以托毒外出。其余内外治疗方法，参照痈疽肿疡门、溃疡门。
方剂：荆防败毒散（参见项部脑疽）

【方歌】膻中疽初起如粟粒状，颜色紫暗坚硬，逐渐出现红肿热痛，由七情化火成毒发于任脉，应当急随证候治疗，若拖延则病情凶险。
【注】此证生于心窝之上，两乳中央，属于任脉经膻中穴。由于脏腑不和，七情失调，火毒凝结而成。初起像粟米，颜色紫暗坚硬，逐渐产生红肿热痛，伴有憎恶寒冷和壮热，适宜紧急服用仙方活命饮加苏叶、薄荷叶发汗。如果出现烦躁作呕、嘴唇焦裂、极度口渴，适宜服用夺命丹清热；等到表证已经消退，紧急服用托里透脓汤；如果疮势不起伏属虚证，适宜服用十全大补汤托毒。但是此处是气海之气所居之处，治疗贵在早，如果延误则毒邪内陷攻里，损伤膜原透气，这属于逆证。其余内外治疗方法，均参照痈疽肿疡门、溃疡门。

[Prescription Verse] Gan Ju (Gan Abscess) arises from Qi stagnation caused by worry and overthinking. It appears on the chest, resembling a grain of millet with a purple, atrophic shape. Accompanied by chills, fever, hardness, and pain, it should be induced to suppurate quickly; if suppuration is delayed, one must guard against the sinking of pathogenic factors into the interior.
[Commentary] This condition is formed by Qi stagnation due to worry and overthinking. It occurs on the anterior chest (the raised fleshy areas on both sides of the chest), below the Zhongfu (LU-1) acupoint of the Lung Meridian, and can affect either the left or right side. Initially, it resembles a millet grain and is green in color; gradually, it turns purple like a Trichosanthes fruit, becoming hard and painful, accompanied by aversion to cold and high fever. If it suppurates quickly with thick pus, it is a favorable sign (Shun). If after ten days the chills and fever do not subside, no pus forms, and the pulse is floating and rapid, one must guard against the sinking of toxins into the interior, which leads to malignant conditions; this is an unfavorable sign (Ni). Initially, Jingfang Baidu San (Atractylodes and Saposhnikovia Decoction for Overcoming Toxins) is suitable to disperse and resolve chills and fever, followed by Neituo Huangqi San (Huangqi Decoction for Internal Support). If it does not suppurate when expected, Shiquan Dabu Tang (Comprehensive Great Tonifying Decoction) should be taken urgently to support the expulsion of toxins. For other internal and external treatments, refer to the sections on Carbuncles and Ulcers (Swelling/Ulceration stages).

[Prescription Verse] Danzhong Ju (Danzhong Abscess) begins as a millet-grain-like nodule, purple in color and hard, gradually developing redness, swelling, heat, and pain. It arises from Fire-Toxin generated by Seven Emotions affecting the Ren Meridian. Treatment must be urgent according to the syndrome; delay leads to ominous outcomes.
[Commentary] This condition occurs above the epigastrium, in the center between the two breasts, belonging to the Danzhong (CV-17) acupoint of the Ren Meridian. It is caused by disharmony of the Zang-Fu organs and imbalance of the Seven Emotions, leading to the condensation of Fire-Toxin. Initially, it resembles a millet seed, is purple and hard, and gradually develops redness, swelling, heat, and pain, accompanied by aversion to cold and high fever. Xianfang Huoming Yin (Immortal Life-Deciding Decoction) added with Perilla Leaf (Zi Su Ye) and Mint Leaf (Bo He Ye) should be taken urgently to induce sweating. If restlessness, vomiting, cracked lips, and extreme thirst occur, Dueming Dan (Life-Taking Pill) should be taken to clear heat. Once the exterior syndrome has subsided, Tuoli Tou Nong Tang (Interior-Supporting Pus-Penetrating Decoction) should be taken urgently. If the lesion fails to rise, indicating deficiency, Shiquan Dabu Tang (Comprehensive Great Tonifying Decoction) should be taken to support the expulsion of toxins. However, this area is where the Qi of the Qi Sea resides; treatment must be early. If delayed, toxins sink into the interior, damaging the membranes and obstructing Qi transmission, which is an unfavorable sign (Ni). For other internal and external treatments, refer to the sections on Carbuncles and Ulcers (Swelling/Ulceration stages).
