人有四肢之间，或头面之上，忽然生疽，头黑皮紫，痛楚异常，此阳症之毒也。治不得法，亦能杀人。盖
阳症之毒，其毒甚骤，即用败毒之药治之，可随手而愈。然而疽与痈，实有不同。痈溃于内，而疽肿于外也。
溃于内者，难于外治；肿于外者，易于内消。虽痈疽之毒，尽由内而发外，无不可内治而外愈也。而疽尤宜内
治，方用消疽汤∶
夏枯草（二两） 忍冬藤（二两） 当归（二两） 连翘（三钱） 生地（三钱） 地榆（三钱）
天花粉（三钱） 白芷（二钱） 甘草（二钱）
水煎服，未溃者二剂即消，已溃者四剂痊愈矣。此方
通治恶疽之方也，凡生疽者，以此方治之，无不神效。盖补血散毒，则血活而毒难留；凉血清火，则血寒而火
易散，疽多阳症，所以治无不宜也。
秘诀∶
消疽汤用夏桔草，忍冬当归二两搅，
连翘二地粉三钱，白芷二钱甘草好。
又治恶疽方∶
荆芥（三钱） 甘草（三钱） 天花粉（三钱） 当归（一两） 玄参（一两） 金银花（八钱）
陈皮（一钱） 蒲公英（五钱） 牛蒡子（二钱）
水煎服，若在咽喉者加桔梗三钱；若在下体者加地榆三钱。
秘诀∶
又有一方治恶疽，荆芥甘粉三钱许，
归玄一两银八钱，陈一英五二牛子，
若在咽喉三钱桔，下体生兮加地榆。
Between the four limbs, or on the head and face, a carbuncle (Ju, a deep-seated suppurative infection) may suddenly appear. The tip of the lesion is black, the skin is purple, and the pain is extremely severe. This is caused by toxic pathogens in Yang syndromes. If treated improperly, it can also be fatal. The toxicity of Yang syndromes develops rapidly; even if anti-toxic herbs are used for treatment, recovery can be achieved promptly. However, Ju and Yong (Yong, a superficial suppurative infection) are actually different. Yong ulcerates internally, whereas Ju swells externally. Lesions that ulcerate internally are difficult to treat externally; those that swell externally are easier to dissipate through internal regulation. Although the toxicity of both Yong and Ju emanates from the interior to the exterior, there is no case where internal treatment cannot lead to external healing. Nevertheless, Ju is particularly suitable for internal treatment. The prescription is Xiaoku Decoction (Xiaoju Tang):
Prunellae Spica (Xiakucao, 2 liang), Honeysuckle Stem (Rendongteng, 2 liang), Angelica Sinensis Root (Danggui, 2 liang), Forsythia Fruit (Lianqiao, 3 qian), Rehmannia Root (Shengdi, 3 qian), Sanguisorba Root (Diyu, 3 qian);
Trichosanthes Root (Tianhuafen, 3 qian), Angelica Dahurica Root (Baizhi, 2 qian), Licorice Root (Gancao, 2 qian).
Decoct with water and take orally. For lesions not yet ulcerated, two doses will eliminate them; for those already ulcerated, four doses will result in complete recovery. This prescription is a general formula for treating malignant carbuncles. Anyone suffering from Ju who uses this prescription will find it remarkably effective. Because nourishing blood and dispersing toxicity promotes blood circulation, making it difficult for toxins to remain; cooling blood and clearing fire lowers blood temperature, facilitating the dispersion of fire. Since Ju mostly belongs to Yang syndromes, treatment is invariably appropriate.
Secret Formula:
Xiaoku Decoction uses Prunella,
Honeysuckle and Angelica each two liang mixed well,
Forsythia, Shengdi, Diyu, and Trichosanthes three qian each,
Angelica Dahurica two qian, Licorice good quality.
Another prescription for treating malignant carbuncles:
Schizonepeta Spike (Jingjie, 3 qian), Licorice Root (Gancao, 3 qian), Trichosanthes Root (Tianhuafen, 3 qian), Angelica Sinensis Root (Danggui, 1 liang), Scrophularia Root (Xuanshen, 1 liang), Honeysuckle Flower (Jinyinhua, 8 qian);
Tangerine Peel (Chenpi, 1 qian), Dandelion (Pugongying, 5 qian), Arctium Seed (Niubangzi, 2 qian).
Decoct with water and take orally. If located in the throat, add Platago Seed (Jiegeng, 3 qian); if located in the lower body, add Sanguisorba Root (Diyu, 3 qian).
Secret Formula:
Another prescription for malignant carbuncles, Jingjie, Gancao, and Tianhuafen about three qian each,
Danggui and Xuanshen one liang each, Jinyinhua eight qian, Chenpi one qian, Pugongying five qian, Niubangzi two qian,
If in the throat add three qian Jiegeng, if growing in the lower body add Diyu.
