Spearmint tea has been studied for its ability to reduce androgens in women, making it one of the few herbal teas with direct hormonal research behind it.
Spearmint tea is one of the more researched herbal teas when it comes to hormonal health. A clinical trial published in Phytotherapy Research found that women with PCOS who drank two cups of spearmint tea daily for 30 days showed a significant reduction in free testosterone levels and an improvement in LH to FSH ratios. The mechanism is thought to involve spearmint’s ability to inhibit 5-alpha reductase, the enzyme that converts testosterone to its more potent form.
For women dealing with PCOS, hirsutism, or androgen-related acne, spearmint tea is sometimes recommended as a supportive, low-risk addition to a broader approach — not as a standalone treatment. The research is specific enough that some functional medicine practitioners include it in hormonal health protocols.
Spearmint is different from peppermint — it’s milder, sweeter, and lower in menthol. When blended with green tea, as in Nevisan’s Spearmint Green, the result is a bright, cooling cup with a clean finish. The green tea adds antioxidants and L-theanine, making the combination genuinely useful rather than just pleasant.
If you’re exploring spearmint tea for hormonal reasons, consistency matters more than quantity. Two cups a day for several weeks is what the research used — not a single strong brew once in a while. Whole-leaf spearmint blended with real green tea is worth seeking out over fannings-based bags.
