【注】此证发生于肾囊（阴囊），表现为红肿、灼热疼痛，身体出现寒热往来，口干想喝冷水，由肝、肾湿热下注至肾囊而成。初起时宜服用荆防败毒散以发汗解表，外用葱白和盐熬汤烫洗；若寒热已退，宜服用清肝渗湿汤以消散湿热；若无效，说明脓势即将形成，急服滋阴内托散；若患者气虚怯弱、食欲减退，宜服用托里透脓汤，外用二味拔毒散围敷肿根。若感到脓胀疼痛，用卧针针刺排脓，流出稠脓者为顺症，流出腥臭液体者病情危险，宜服用托里排脓汤，外用琥珀膏贴敷；待肿胀消退、脓液减少、疼痛减轻时，使用生肌散、生肌玉红膏以促进肌肉生长和伤口愈合。此痈本源于肝、肾，以滋阴培补气血为关键。在生肌敛口阶段，早晨服用六味地黄汤，晚上服用人参养荣汤，滋补效果显著。此证若失治，溃烂深重露出睾丸者预后危险，然而不可放弃治疗，宜用杉木灰覆盖保护，苏子叶包裹患处，让患者仰卧，静养调理，或许可以取得疗效。

Yinshi Chuang (Pubic Louse Disease) occurs within the pubic hair region, caused by turbid heat in the Liver and Kidney due to uncleanliness. Symptoms include itching; scratching causes redness with purple spots. If lesions appear like beans or cakes, forming crusts resembling wax, it indicates Meiyang Du (Syphilis).
[Note] This condition is also known as "Eight-Legged Bug," growing inside the root of the pubic hair. It arises from turbid Qi generating heat in the Liver and Kidney, combined with stagnation of filth due to improper washing after sexual intercourse. The itching is unbearable; scratching breaks the skin, turning it red with purple spots in the center. Internally, use Lubai Dihuang Wan; externally, puncture with a needle to remove lice, then apply Yinxing Wuyou San for easy healing. If nodules like beans or cakes appear in the pubic region, itching and crusting like wax, this is Yangmei Du (Syphilis), which should be treated according to protocols for Yangmei Du.
Yinxing Wuyou San
Ingredients: Shuiyin (Mercurius, prepared with lead), Qingfen (Calomel), Xingren (Armeniacae Semen Amarum, peeled and cored, pounded into paste), Lushen (Aloe), Xionghuang (Realgar), Yelangdu (Stellerae Radix) (each 1 qian), Shexiang (Moschus) (1 fen).
Preparation: Except for Shuiyin and Xingren paste, grind all other herbs together, sift into fine powder, then mix evenly with Yinxing (Ginkgo seed). First, wash the area with a decoction of Shichangpu (Acori Tatarinowii Rhizoma). Puncture with a needle to remove lice, then mix the powder with saliva for topical application to allow medicinal qi to penetrate, preventing recurrence. Strictly avoid beef, dog meat, and softshell turtle meat.
[Fang Ge] Yinxing Wuyou San stops itching, treating heat-stagnation pubic louse disease; Lead-prepared mercury, calomel, apricot kernel, aloe, realgar, stellera root, and musk are used.
Lubai Dihuang Wan (Six-Ingredient Rehmannia Pill with added Aloe and Honey-fried Phellodendri Cortex. Indicated for facial freckles.)
Shennang Hongzhong Fa Wei Yong (Scrotal Carbuncle) presents with redness and swelling, accompanied by chills, fever, dry mouth, and pain. It is caused by damp-heat flowing downward from the Liver and Kidneys. If neglected, deep ulceration exposing the testicle leads to a poor prognosis.
[Note] This condition occurs on the scrotum, presenting with redness, swelling, burning pain, systemic chills and fever, and dry mouth with desire for cold drinks. It results from damp-heat of the Liver and Kidney sinking to the scrotum. In the early stage, use Jingfang Baidu San to induce sweating; externally, scald with a decoction of Scallion and Salt. Once chills and fever subside, use Qinggan Shen Shi Tang to resolve damp-heat. If ineffective, pus formation is imminent; urgently use Ziyin Neituo San. For patients with weak Qi and poor appetite, use Tuoli Tou Nong Tang, applying Erwei Baidu San around the base of the swelling. If there is distending pain from pus, prick with a flat-headed needle. Flow of thick pus indicates a favorable course; flow of foul-smelling fluid indicates danger. Use Tuoli Pai Nong Tang internally and Hupo Gao externally. When swelling subsides, pus decreases, and pain lessens, use Shengji San and Shengji Yuhong Gao to promote tissue regeneration and wound closure. Since this carbuncle originates from the Liver and Kidney, nourishing Yin and tonifying Qi and Blood is essential. During the tissue regeneration phase, take Liuwu Dihuang Tang in the morning and Renshen Yangrong Tang in the evening for excellent tonic effects. If neglected, deep ulceration exposing the testicle is dangerous, but treatment should not be abandoned. Apply fir wood ash and wrap with Perilla frutescens leaves. Have the patient lie supine and rest quietly; recovery may be achieved.
