Spearmint tea has gained attention in PCOS communities for its potential anti-androgen effects, particularly for hirsutism.
What the research shows:
• Two small clinical trials found that spearmint tea (2 cups daily for 30 days) significantly reduced free testosterone levels • Self-reported improvement in hirsutism scores • The anti-androgen effect appears to be specific to spearmint (not peppermint or other mints)
Important context:
• Study sizes are very small (the most cited study had 42 participants) • The studies lasted only 30 days — long-term effects aren't well studied • The testosterone reduction was statistically significant but the clinical impact on hirsutism was modest • Hirsutism changes slowly — visible results would take months even if the hormonal effect is real
How to try it: • 2 cups of spearmint tea daily (the studied protocol) • Spearmint capsules are also available but less studied • No significant safety concerns at this dose
Spearmint tea is safe, inexpensive, and pleasant. The evidence is promising but limited. It's reasonable to add to your routine, but expectations should be realistic — it's a mild intervention, not a substitute for proven anti-androgen treatments like spironolactone.
