痈疽有小白头者，初起即以膏子点之，毒轻者自消，毒重者出水，甚至流黑汁而愈，最
甚者即未散，亦大杀其毒矣。
砂膏 治痈疽肿毒，并治瘰 ，点落 痣等。
砂（生用，一钱） 石矿灰（一两，炒黄色） 白丁香（三钱，炒黄色） 黄丹（半斤，生用）
碱（一斤，淋水五碗）
前四味研为极细末。次将碱水煎作一碗，成膏待冷以前未入膏，和匀藏瓷器中，一应
毒物以膏点之。白丁香即麻雀儿屎，用坚尖者，不用软颓者。
六灰膏 治发背、疔疮、疖子、肿毒、 疮、痔疮、痣子、 子，其功用与 砂膏同
也。
灰苋 桑木 枣木 养麦料 茄科（各烧为灰） 石矿灰（研细）
上件多少不妨。和匀，汤泡水淋，淋下之水，煎成膏如糊，装瓷器中，一应毒物，以
膏点之。若点疡疮、痔疮，待烂去少许，再点之，再烂去，如是渐渐点去。
援生膏 治诸般恶疮，及瘰 、鼠疮才起者，点破即愈。
血竭（一钱） 蟾酥 轻粉（各三钱） 麝香（五分） 雄黄（五钱） 乳香 没药（各一钱 以 上药俱
为极细末。
上用荞麦秸灰，或真炭灰一斗三升，淋灰汤八九碗，用栗柴或桑柴文武火煎作三碗，
取一碗收留，将二碗盛于好瓷器内，候温将药末入灰汤内，用铁瓢或桑柳枝右搅，又用
好细锻石一升，入药灰汤，搅匀，取出候冷过宿，盛于小白瓷罐内。凡遇诸恶疮，点在
当头，一日二次，次日又一次，疮头食破，约五分血水出为妙，恐日久药干，将前收留灰
汤和用。
对于痈疽初起时出现小白头的情况，应立即使用药膏点涂患处。毒邪较轻的，自然会消散；毒邪较重的，会渗出液体，甚至流出黑色汁液而痊愈；最严重的情况，虽然肿块未能完全消散，但也能极大地削弱毒势。
砂膏：治疗痈疽肿毒，以及瘰疬、点除黑痣等病症。
配方：硇砂（生用，一钱）、石矿灰（一两，炒至黄色）、白丁香（三钱，炒至黄色）、黄丹（半斤，生用）、碱（一斤，用水五碗淋滤提取）。
制法与用法：将前四味药材研磨成极细粉末。然后将碱水煎煮浓缩至一碗，在尚未凝固成膏且未加入药粉之前，将药粉与碱水混合均匀，存入瓷器中。所有毒邪疮疡均可用药膏点涂。白丁香即麻雀粪便，应选用坚硬尖锐者，弃用松软颓败者。
六灰膏：治疗发背、疔疮、疖子、肿毒、恶疮、痔疮、黑痣、肉赘等，其功效与砂膏相同。
配方：灰苋、桑木、枣木、荞麦秸秆、茄科植物茎叶（各烧制成灰）、石矿灰（研细）。
制法与用法：上述药材用量不拘。将其混合均匀，用热水浸泡并淋滤，收集淋下的滤液，煎煮浓缩成糊状膏体，装入瓷器中。所有毒邪疮疡均可用药膏点涂。若用于点涂溃疡或痔疮，需待腐肉脱落少许后再次点涂，反复多次，直至逐渐清除干净。
援生膏：治疗各种恶疮，以及初起的瘰疬、鼠疮，点破后即可痊愈。
配方：血竭（一钱）、蟾酥、轻粉（各三钱）、麝香（五分）、雄黄（五钱）、乳香、没药（各一钱）。以上药物均研磨成极细粉末。
制法与用法：取荞麦秸秆灰或真炭灰一斗三升，用水淋滤出八九碗灰汤。用栗柴或桑柴，以文火武火交替煎煮浓缩至三碗，保留其中一碗备用，将另外两碗盛于优质瓷器中。待温度适宜时，将药末倒入灰汤中，用铁瓢或桑柳枝向右搅拌。再加入优质细锻石一升，与药灰汤搅匀，取出后放置过夜冷却，最后盛入小白瓷罐内。凡遇各种恶疮，点在疮头正中，每日两次，次日再点一次，使疮头腐蚀破溃，流出约五分量的血水为最佳效果。若担心日久药膏变干，可用之前预留的灰汤调和使用。
When a carbuncle or furuncle (Yongju, 痈疽) initially presents with a small white head, it should be treated immediately by applying ointment to the lesion. If the pathogenic toxin is mild, it will resolve spontaneously; if severe, it will exude fluid, and in extreme cases, discharge black fluid before healing. Even in the most severe instances where the swelling does not fully dissipate, the toxicity is significantly reduced.
Sha Gao (Nahsha Ointment): Treats carbuncles, furuncles, swelling, and toxins; also used for treating scrofula (Luoli, 瘰疬) and removing moles.
Ingredients: Nahsha (Sal Ammoniac, Naohua, 硇砂, raw, 1 qian), Stone Mine Ash (Shikuanghui, 石矿灰, 1 liang, stir-fried until yellow), Bai Dingxiang (White Dingo, 白丁香, i.e., sparrow droppings, 3 qian, stir-fried until yellow), Huangdan (Lead Monoxide, 黄丹, 8 liang, raw), Alkali (Jian, 碱, 1 jin, leached with five bowls of water).
Preparation and Usage: Grind the first four ingredients into an extremely fine powder. Then, boil the alkali water down to one bowl. Before it solidifies into a paste and before adding the powder, mix the powder evenly with the alkali water and store in a porcelain vessel. Apply this ointment to all toxic lesions. For Bai Dingxiang, select hard, sharp sparrow droppings; discard soft, decayed ones.
Liuhui Gao (Six-ash Ointment): Treats back carbuncles (Fabei, 发背), ding sores (Dingchuang, 疔疮), boils (Jiezi, 疖子), swelling and toxins, malignant ulcers, hemorrhoids, moles, and skin tags. Its efficacy is identical to that of Sha Gao.
Ingredients: Ash from Chenopodium album (Hui Xian, 灰苋), Mulberry wood (Sangmu, 桑木), Jujube wood (Zaomu, 枣木), Buckwheat stalks (Yangmai liao, 养麦料), Solanaceae stems/leaves (Qieke, 茄科) [each burned to ash], Stone Mine Ash (Shikuanghui, 石矿灰, finely ground).
Preparation and Usage: The proportions of the above ingredients are flexible. Mix them evenly, soak in hot water, and leach. Collect the leachate and boil it down into a paste-like ointment. Store in a porcelain vessel. Apply to all toxic lesions. When treating ulcers or hemorrhoids, apply repeatedly after some necrotic tissue has sloughed off, continuing until the lesion is gradually cleared.
Yuansheng Gao (Yuansheng Ointment): Treats various malignant ulcers and early-stage scrofula or rat-chancres (Shuchuang, 鼠疮); healing occurs once the lesion is punctured by the ointment.
Ingredients: Dragon's Blood (Xuejie, 血竭, 1 qian), Toad Venom (Chansu, 蟾酥, 3 qian), Calomel (Qingfen, 轻粉, 3 qian), Musk (Shexiang, 麝香, 5 fen), Realgar (Xionghuang, 雄黄, 5 qian), Frankincense (Ruxiang, 乳香, 1 qian), Myrrh (Moyao, 没药, 1 qian). All ingredients must be ground into an extremely fine powder.
Preparation and Usage: Take one dou three sheng of buckwheat straw ash or pure charcoal ash, and leach with water to obtain eight to nine bowls of ash liquor. Boil using chestnut wood or mulberry wood, alternating between moderate and high heat, until reduced to three bowls. Reserve one bowl; place the remaining two bowls in a fine porcelain container. When warm, add the powdered medicines to the ash liquor and stir clockwise with an iron ladle or mulberry/willow branch. Add one sheng of fine refined alum (Duanshi, 锻石) to the medicinal ash liquor, stir well, remove, and let cool overnight. Store in a small white porcelain jar. For any malignant ulcer, apply directly to the center of the head twice daily, and again the next day. The goal is for the ulcer head to erode and release approximately five fen of blood and fluid. If the ointment dries out over time, use the reserved ash liquor to reconstitute it.
