【方歌】痘痈毒留经络中，发无定处肿不红，留于肌肉为治易，
结于骨节难成功。
【注】此证因出大痘，浆灌不足，以致毒浆不得透发，留结经
络之中，随处可生。小如李者为毒，大如桃者为痈，漫
肿不红，亦无焮痛，身热多烦。若生单个者，毒在肌肉
属顺，易治；连发数处者，船小载重属险；若结于骨节
之间，或成对发出者，其毒已盛，溃破之后，渗泄气血
，不能敛口属逆。初发不可强消，俱宜服透脓散，外敷
乌龙膏；脓熟针之，加味太乙膏贴之；若气血虚弱者，
兼服保元汤。溃后潮热全退，毒气方净，否则他处又发
。忌生冷、硬面、发物。

当归姜枣共黄耆。

加味太乙膏（见溃疡门）
【方歌】葡萄疫同葡萄状，感受疠疫郁凝生，遍身发点青紫色，
毒攻牙齿类疳形。
【注】此证多因婴儿感受疠疫之气，郁于皮肤，凝结而成。大
、小青紫斑点色，状如葡萄，发于遍身，惟腿胫居多；
甚则邪毒攻胃，以致牙龈腐烂，臭味出血，形类牙疳，
而青紫斑点，其色反淡，久则令人虚羸。初起宜服羚羊
角散，久虚者宜服胃脾汤，米疳水漱口。以非疳散日擦

[Prescription Verse] The toxin of carbuncle (carbuncle) remains within the meridians, appearing at unpredictable locations with swelling but no redness; if it stays in the muscles, treatment is easy, but if it knots in the joints, success is difficult.
[Annotation] This condition arises because the pustules during smallpox were insufficiently filled with fluid, causing the toxin and fluid to fail to emerge, thus remaining and knotting within the meridians, potentially occurring anywhere. Those small as a plum are termed "toxin" (du), while those large as a peach are termed "carbuncle" (yong). They present as diffuse swelling without redness, nor with burning pain, accompanied by fever and irritability. If a single lesion appears, the toxin is in the muscles, which is a favorable pattern (shun) and easy to treat; if multiple lesions appear consecutively, it is like a small boat carrying heavy weight, indicating a dangerous pattern (xian); if it knots between joints or appears in pairs, the toxin is abundant, and after ulceration, the leakage of qi and blood prevents wound closure, indicating an unfavorable pattern (ni). At the initial stage, do not force resolution; all cases should take Tou Nong San (Penetrating Pus Powder) externally applied with Wu Long Gao (Black Dragon Ointment); once pus matures, puncture with a needle and apply Jia Wei Tai Yi Gao (Modified Tai Yi Plaster); for those with deficient qi and blood, concurrently take Bao Yuan Tang (Protect the Origin Decoction). After ulceration, tidal fever must completely subside before the toxin is considered cleared; otherwise, it will reappear elsewhere. Avoid raw/cold foods, hard noodles, and triggering foods.
Formula: Bao Yuan Tang (Protect the Origin Decoction)
Composition: Ren Shen (Ginseng Radix), Bai Zhu (Atractylodis Rhizoma, stir-fried with soil), Dang Gui (Angelicae Sinensis Radix), Huang Qi (Astragali Radix) (each 1 qian), Gan Cao (Licorice Radix et Rhizoma, honey-fried, 3 fen), Sheng Jiang (Zingiberis Rhizoma Recens, one slice), Hong Zao (Jujubae Fructus, flesh, two pieces). Use two zhong of water, decoct to eight fen, take far from meals.
[Prescription Verse] Bao Yuan Tonifies true yuan qi, especially suitable for spleen-stomach deficiency; Ginseng, Atractylodes, honey-fried Licorice, together with Angelica, Ginger, and Jujuba complement Astragalus.
Another Formula: Tou Nong San (see Chapter on Swelling and Ulceration), Wu Long Gao (see Chapter on Swelling and Ulceration).

[Prescription Verse] Grape plague resembles grapes, arising from epidemic qi stagnation and condensation; purple-blue spots erupt over the body, toxin attacks teeth resembling canker sores.
[Annotation] This condition often occurs when infants contract epidemic qi, which stagnates in the skin and condenses into formation. Large and small purple-blue spots, shaped like grapes, erupt over the body, mostly on the lower legs; severely, pathogenic toxin attacks the stomach, causing gum rot, foul odor, and bleeding, resembling dental canker (ya gan), while the purple-blue spots become paler, leading to emaciation over time. At onset, Ling Yang Jiao San (Antelope Horn Powder) is suitable; for chronic deficiency, Wei Pi Tang (Stomach-Spleen Decoction) is suitable, rinsing with rice wash water. Applying Fei Gan San (Non-Canker Powder) four to five times daily yields quick results. Recently, middle-aged individuals with lower jiao deficiency have also suffered this condition, treated similarly.

Use two zhong of water, ten leaves of Zhu Ye (Bambusae Folium), decoct to six fen, take far from meals.
[Prescription Verse] Antelope Horn Powder contains Ophiopogon, Scutellaria, Anemarrhena, Arctium, Saposhnikovia, Licorice, and Scrophularia; suitable for early grape plague, adding Bamboo Leaves makes efficacy divine.

Use two zhong of water, decoct to six fen, take far from meals. For weak persons with spontaneous sweating, remove Glehnia, add Ren Shen (Ginseng Radix) and Huang Qi (Astragali Radix) each 5 fen.
[Prescription Verse] Stomach-Spleen Decoction treats grape plague, suitable for long-term weakness and emaciation; Atractylodes, Polygala, Ophiopogon, Schisandra, Glehnia, Licorice, Poria, and Citrus peel.
