While I drink spearmint tea every single day, I will admit that I never really looked into the research on it; I just assumed there had to be solid evidence since it was so commonly suggested.

What does the literature say?

There are numerous studies on the use of spearmint in rats in which PCOS conditions were induced. That’s not really compelling evidence to me that spearmint will work in humans, so I won’t discuss those studies here.

The first (of two) studies to try using spearmint tea to treat excess androgens occurred in Turkey and recruited 21 women who experienced hirsutism, 12 of whom had also been diagnosed with PCOS (Akdogan et al. 2007). Twice daily for five days, the women consumed spearmint tea.
