The aim of this study is to elucidate the effects of red yeast rice on the improvement of symptoms in patients with polycystic ovary syndrome（PCOS）, and to analyze the dose-response relationship between intestinal microbiota and its metabolite, hydroxyindole, and clinical indicators of PCOS.
The main questions it aims to answer are:
How effective is red yeast rice in treating PCOS? Does the indole metabolic pathway of gut microbiota play a crucial role in the improvement of PCOS symptoms by red yeast rice? Participants will take 6 grams of red yeast rice daily for 6 months, and records will be kept of their PCOS clinical symptoms and indicators before the intervention, at the 3rd month post-intervention, and at the 6th month post-intervention. Additionally, biological samples from feces and serum will be collected at these time points.
Female patients aged 18-40 years old

Pregnant women (confirmed via urine/serum hCG)
Patients with concomitant infectious diseases or severe dysfunction of multiple systemic organs
