It is proposed that

yangming

（阳明） turbid heat and dysfunction of the

chong

and

ren

（冲任） vessels are the key pathogenesis underlying abnormal uterine bleeding caused by polycystic ovary syndrome （PCOS）. The general principle of tr

eatment is to clear and drain the

yangming

channel and resolve turbid heat. During the acute bleeding phase， the approach is to clear heat， cool the blood， consolidate the

chong

vessel， and stop bleeding. During the chronic phase， the focus shifts to resolving phlegm and removing stasis， unblocking and purging

qi

movement. And during the late stage， the method of boosting

qi

and nourishing

yin

， consolidating the root and regulating menstruation is suggested. In clinical practice， the self-formulated

Yishen Quzhuo Formula

（益肾祛浊方） serves as the foundation， with flexible modifications and adjustments made according to disease stage and individual clinical presentation.
