夫便毒者，生于小腹下，两腿合缝之间，其毒初发，寒热交作，腿间肿起疼痛是也。夫
肾为作强之官，所藏者精与志也。男女大欲不能以直遂其志，故败精搏血，留聚中途而结为
便毒矣。夫人脚腿与小腹合逢之间，精气所出之道路也。或触景而动心，或梦寐而不泄，既
不得偶合阴阳，又不能忘情息念，故精与血交滞而成肿结也。初起，慎不可用寒凉之药，恐
气血愈结，不得宣散，反成大患。惟当发散寒气，清利热毒，使精血宣畅则自然愈矣。

Biandu (Groin Abscess) is a disease occurring in the lower abdomen, between the inner seams of both thighs. Upon initial onset, it presents with alternating chills and fever, accompanied by swelling and pain in the thigh region.
The Kidney is referred to as the "Official of Strength and Endurance" (Zuoqiang), storing Jing (Essence) and Zhi (Will). When men and women cannot fulfill their sexual desires directly, defeated Jing (Essence) and Blood contend and stagnate midway, condensing into Biandu (Groin Abscess). The junction where the legs meet the lower abdomen is the pathway for the emergence of Jing (Essence) and Qi (Vital Energy). Sometimes, visual stimuli stir the heart/mind, or nocturnal emissions occur without release; since Yin-Yang union cannot be achieved, and emotional attachments and thoughts cannot be extinguished, Jing (Essence) and Blood become mutually stagnant, forming swellings and nodules. In the early stage, one must strictly avoid using cold-natured herbs, lest the Qi and Blood become further condensed and unable to disperse, thereby causing greater harm. Instead, one should only dissipate cold pathogens and clear/drain heat-toxins, allowing Jing (Essence) and Blood to circulate freely, leading to natural recovery.
