In Chinese medicine, there is no corresponding name for polycystic ovary syndrome, and it is mostly categorized as “infertility”, “late menstruation”, “amenorrhea” and so on according to the clinical symptoms of the patients, and it is mostly identified as kidney qi deficiency and weakness. Chinese medicine practitioners usually recognize the symptoms as kidney qi deficiency, spleen deficiency, phlegm-dampness, qi stagnation and blood stasis, etc., and can choose traditional Chinese medicines such as eucommia, sangzhusheng, atractylodes macrocephala, hemixia, peach kernel, safflower, etc. for the diagnosis.
