Abstract: Recurrent vulvovaginal candidiasis is intractable to cure but easy to relapse with a long-term lingering course. Based on the perspective of harmonizing pathogenic qi and nourishing healthy qi， Xia Guicheng， a master of traditional Chinese medicine， regarded separating dispersion and mobilizing discharge as the basic therapeutic methods， regulating the overall vaginal internal environment as the foothold and reconstructing the vaginal micro-ecology as the basis， thus promoting the recovery of the dominant bacterial community， such as lactic acid bacteria， and harmonizing the local immune micro-ecology so as to achieve the purposes of cure diseases. In addition， a modified Ermiao granule has been developed and applied in the clinic.
