A cheap, safe tea with real trial evidence for gently lowering the androgens behind PCOS hair growth and acne.
Spearmint — usually taken as a tea — has a mild anti-androgen effect, meaning it gently lowers the male-type hormones (like testosterone) that are often raised in PCOS. Those androgens drive some of the most distressing PCOS symptoms: unwanted facial and body hair (hirsutism), hormonal acne and thinning scalp hair.
There is real, if modest, evidence. A 2010 randomised trial in 42 women with PCOS found that drinking spearmint tea twice daily for 30 days significantly lowered free and total testosterone. The important honest nuance: hormone levels dropped within a month, but the objective hirsutism score did not change in that short window — because hair follicles cycle slowly and visible improvement takes several months. So spearmint genuinely shifts the hormones; you just need patience to see the cosmetic effect.
PCOS with signs of androgen excess: unwanted hair growth, persistent hormonal acne, or oily skin. It is a gentle, low-risk addition rather than a powerful treatment.
The studied dose is two cups of spearmint tea per day (roughly 5 g of dried leaf, or 3–4 tea bags). Capsule extracts exist but the tea is what the trials used. Give it 3–6 months for visible effects on hair.
Spread the two cups across the day. Consistency matters more than timing — the hormone effect builds with daily use over weeks. Note: it's spearmint (Mentha spicata), not peppermint.
Very well tolerated. The most common effect is mild digestive relaxation (spearmint is traditionally a digestive aid). Mint-sensitive people may notice mouth or stomach irritation.
Inositol or berberine for the insulin side of PCOS, and zinc, which also has mild anti-androgen and skin benefits.
No major drug interactions, but because it lowers androgens, avoid relying on it during pregnancy or active conception attempts without medical advice.
Anyone pregnant or trying to conceive should check first. It is not a substitute for medical treatment of severe hirsutism, where prescription options work faster.
Plain spearmint (Mentha spicata) tea — loose leaf or good-quality tea bags. If using a capsule, look for a standardised Mentha spicata extract.
Spearmint tea is a cheap, safe, evidence-backed way to gently lower the androgens behind PCOS hair and acne. Two cups a day measurably shifts hormones within a month, though visible hair improvement takes several months of consistency.
