〔薛〕杨梅疮乃天行时毒，亦有传染而患之，或禀赋所得者，受证在肝，故多起
于下部，治失其宜，多致蚀伤眼目，腐败肾茎，拳挛肢节。初起之时，上体多者先
用荆防败毒散。下体多者先用龙胆泻肝汤。大便秘者用大连翘饮，后用换肌消毒散。
若蚀伤眼目，兼用九味芦荟丸、六味地黄丸。肢节拳挛，兼用蠲痹解毒汤。若因脾
胃亏损而不能愈者，先用异功散，后用换肌消毒散。若用轻粉之药，多致败证也。
按∶杨梅疮起于近代，多淫夫御不洁之妇，传染而致者，其在小儿，得之乳
抱传染者轻，得之父母遗体者重，治法与大人同，更当求之专科，薛氏治法，未可
尽遵用也。

[Xue Ji] Yangmei chuang (Syphilis/Kanekuri disease) belongs to Tianxing shidu (epidemic toxic pathogens). It can also be contracted through infection or acquired congenitally. The pathogenic factor is received by the Liver, so it often originates from the lower part of the body. If treatment is inappropriate, it may lead to damage to the eyes, corruption of the kidneys and penis, and flexion contracture of the limbs and joints. At the initial stage, if symptoms are more prevalent in the upper body, Jingfang Baidu San (Atractylodes and Saposhnikovia Decoction to Overcome Toxic Pathogens) should be used first. If symptoms are more prevalent in the lower body, Longdan Xiegan Tang (Gentiana Decoction to Drain the Liver) should be used first. For those with constipation, Dalianqiao Yin (Large Forsythia Drink) is used, followed by Huanji Xiaodu San (Muscle-Replacing Detoxification Powder). If the eyes have been eroded, Jiuwei Lushui Wan (Nine-Ingredient Aloe Pill) and Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill) are used concurrently. For flexion contracture of the limbs and joints, Juanbi Jiedu Tang (Bi-Syndrome-Dispelling and Detoxification Decoction) is used concurrently. If the condition cannot be cured due to Spleen and Stomach deficiency, Yigong San (Yi-Gong Powder) is used first, followed by Huanji Xiaodu San. The use of Qinfen (Calomel/Mercurous chloride) drugs often leads to a deterioration into a defeat syndrome (Bai Zheng).
Commentary: Yangmei chuang emerged in recent times, mostly caused by promiscuous men contacting unclean women, leading to transmission. In children, those infected through nursing and holding have a milder condition, while those inheriting it from their parents (congenital transmission) have a severe condition. The treatment methods are the same as for adults, but one should seek specialized pediatric diagnosis and treatment. Xue's treatment methods should not be blindly followed.
Huanji Xiaodu San (also known as Caixie San): Treats Yangmei chuang, effective regardless of whether it is newly onset or long-standing.

All in equal parts.
