Spearmint Tea Swap out your coffee or soda with spearmint tea, and you may be taking a step to better manage your PCOS. Drinking spearmint tea has been shown to lower testosterone levels and reduce the appearance of unwanted hair growth in people with a PCOS diagnosis. And because spearmint tea is naturally sugar-free — assuming you aren't adding any honey or sugar — it's also a great beverage that won't increase your blood sugar levels.
