A few small, short studies, including one in women with PCOS and one in women with hirsutism, found lower free testosterone levels after drinking spearmint tea twice a day for about 5 days to a month. The research base is very small and does not show lasting benefit for acne or hair growth, and it does not replace treatment from a clinician.
People with PCOS-related symptoms who also see a clinician for treatment. Whether it suits you depends on your health, medicines and test results — ask a clinician.
