Spearmint Tea

Reviewed by the Nimbera editorial team · Last updated May 2026

Grant P. (2010) "Spearmint herbal tea has significant anti-androgen effects in polycystic ovarian syndrome. A randomized controlled trial." Phytotherapy Research, 24(2):186-8 (PMID 19585478). N=42 women randomized to spearmint tea vs. placebo herbal tea twice daily for 30 days; free and total testosterone fell significantly (p<0.05) in the spearmint group.$5-12/month

How to use

Steep one spearmint tea bag or 1 tsp dried spearmint leaves in 240 ml of boiling water for 5-7 minutes. Drink two cups daily, ideally morning and evening. Allow at least 6-8 weeks before evaluating results, as androgen-driven sebum cycles are slow to shift.

How it works

Spearmint contains rosmarinic acid and other phenolics that suppress 5-alpha-reductase activity and reduce circulating free testosterone, thereby decreasing androgen-driven sebum production.

Where to buy

Grocery stores, health food stores, and online (look for pure spearmint, not peppermint blends). Brands such as Celestial Seasonings, Twinings, and Frontier Co-op are widely available.

Typical cost: $5-12/month

Safety notes

Avoid in pregnancy - spearmint has historically been used as an emmenagogue. May lower testosterone; consult a physician before use if you have a hormone-sensitive condition or are on hormone therapy. Large amounts may interact with medications metabolized by CYP enzymes. Not a substitute for prescribed anti-androgen therapy.

  • Interactions can occur with prescription medications, blood thinners, and immunosuppressants.
