Spearmint Tea for PCOS: Does It Really Work?

Spearmint tea has some real, if limited, research behind it for PCOS symptoms like excess facial hair. Here is what it can and cannot do, and how to use it sensibly.

By the DietGhar team

Short answer: spearmint tea may help a little with one specific PCOS symptom, unwanted facial and body hair, by modestly lowering free testosterone. It is not a cure, it will not fix irregular cycles on its own, and it will not cause weight loss. The research behind it is small but real, and two cups a day is cheap and safe for most people, worth adding on top of a proper PCOS diet, not instead of one.

PCOS affects roughly 1 in 5 women in India, and it is one of the most common reasons clients come to the DietGhar team confused and worn out from conflicting advice. A herbal tea that sounds too simple to matter is naturally going to raise doubt, so here is what the actual studies say, not what wellness pages claim they say.

What does spearmint tea actually do for PCOS?

Spearmint (Mentha spicata) contains compounds with a mild anti-androgen effect, meaning they may lower the activity or levels of male hormones like testosterone in the body. In PCOS, excess androgens drive several of the most bothersome symptoms: hirsutism (extra facial or body hair, often on the chin, upper lip, or jawline), jawline acne, and thinning scalp hair.

Using spearmint for this is not a new idea. It has been used in parts of the Middle East as a traditional remedy for excess hair growth long before researchers tested it in a lab. That history explains why spearmint specifically, and not some other mint, became the focus of the studies that exist today.

What does the research really show?

The most cited study is a small randomized trial where women with PCOS and hirsutism drank spearmint tea twice a day for 30 days. By the end of the month, the spearmint group showed a measurable drop in free testosterone compared to a placebo-tea group, along with a modest improvement in self-reported hirsutism. A few smaller follow-up studies found broadly similar, though not dramatic, results.

The catch matters just as much as the result: these trials are small, usually a few dozen women, over about a month. There is no large trial confirming the effect across thousands of women, no data on what a year of daily use looks like, and no evidence it helps with irregular periods, insulin resistance, or weight gain. Anyone claiming spearmint tea treats PCOS is overselling a genuinely small finding.

What the research does support is this: spearmint tea may nudge free testosterone down slightly, which for some women shows up as a bit less new hair growth or less oily skin over several weeks, not days. That is a modest win, but an honest one, and modest wins are still worth having when you are managing a chronic condition.

How much spearmint tea should you drink, and when?

The amount that has actually been tested is about 2 cups a day, generally one in the morning and one in the evening, for around 30 days before you reassess. There is no research showing more speeds up results.

• How to make it: Steep dried or fresh spearmint leaves in hot water for 5 to 10 minutes. Fresh spearmint (pudina) works fine if you cannot find spearmint tea bags.
• When to drink it: Any time works, though many women prefer it after meals since it also eases mild bloating. Avoid it right before bed if it sends you to the bathroom overnight.
• How long before you notice anything: At least 4 to 6 weeks. This is a slow, hormonal effect, not an overnight one. No change after 2 to 3 months usually means it is not doing much for your body specifically.
• Is it caffeine-free? Yes, which makes it a solid swap for an evening chai or coffee, especially if you also deal with PCOS-related sleep trouble.

Spearmint vs peppermint: does it matter?

Yes, and this is a common mix-up. The androgen-lowering research used spearmint, not peppermint. Peppermint (Mentha piperita) is a different plant and has not shown the same effect in studies, some early animal research even hints it might work the opposite way. Check labels carefully. Many packaged "mint tea" blends sold in India mix the two or do not say which mint they contain.

Who should be careful with spearmint tea?

Spearmint tea is generally safe for healthy adults in normal amounts, but a few groups should check with a doctor first.

• Pregnant women: Spearmint in large amounts has traditionally been avoided in pregnancy across several cultures, and there is not enough research to call it safe in concentrated doses. Speak to your doctor if you are pregnant or trying to conceive.
• People with low blood pressure: Spearmint has a mild blood-pressure-lowering effect in some people. If you already run low, watch how you feel and do not stack it carelessly with other things that lower blood pressure.
• Anyone on hormonal medication or fertility treatment: Mention it to your doctor if you are on birth control, anti-androgen medication like spironolactone, or fertility treatment, since it may affect androgen levels alongside them.
• People on blood thinners or diabetes medication: The interaction evidence is thin, but thin evidence is not the same as no risk. A quick check with your doctor or pharmacist costs nothing.

None of this makes spearmint tea dangerous for most people. It just means what any responsible dietitian would say about any herbal habit: check with a doctor if you are pregnant, on medication, or managing another condition alongside PCOS.

Is spearmint tea a real PCOS treatment, or just a nice-to-have?

Honestly, a nice-to-have. PCOS is a hormonal and metabolic condition, and the biggest, most consistently proven lever for managing it is diet, specifically a low-glycemic, high-protein, high-fibre eating pattern that keeps insulin levels steady. Insulin resistance sits at the center of most PCOS cases in Indian women, driving weight gain, irregular cycles, and the androgen excess that spearmint tea only makes a small dent in.

A cup of spearmint tea alongside white rice, sugary chai, and fried snacks all day will not move the needle much. The same tea alongside a plate built around dal, vegetables, whole grains in controlled portions, and enough protein at each meal is a sensible combination. This is exactly the kind of plan the DietGhar team builds for PCOS clients, tailored to your food, your symptoms, and your routine, not a generic template pulled off the internet.
