Spearmint Tea for PCOS (2026): Evidence, Dosage, Results

Key Takeaways

Spearmint tea for PCOS is popular because small clinical studies suggest it can lower androgens, but expectations need to be realistic.
Small trials found statistically significant drops in free (and sometimes total) testosterone over 5-30 days, but objective hair-score changes were not seen in 30 days.
Not all mint is the same: Clinical evidence for lowering androgens is specific to spearmint (Mentha spicata). Peppermint is mostly studied for digestive benefits, not for PCOS-related hormone issues.
Expect temporary side effects: Some people report initial cycle changes or acne flares as hormones shift during the first few weeks.
Consistency is important: Drink two cups daily, brewed correctly, for at least 2-3 months to see changes in hair or skin. Hormone levels may change sooner.

Medical note: This is educational content, not medical advice. If you’re pregnant/trying to conceive, have liver/kidney disease, GERD, or take hormone-active or hepatotoxic meds, talk to a clinician before using spearmint therapeutically.

Why the Internet is Obsessed with Spearmint Tea (And What Science Actually Says)

If you’ve visited PCOS forums or skincare TikTok, you’ve probably seen claims like, “This tea cleared my hormonal acne!” or “My chin hair stopped growing after drinking spearmint!”

It almost sounds too good to be true. How could a simple herbal tea help with something even specialists find challenging? I was skeptical too, so I looked into the clinical research.

Here’s what I found: Spearmint tea isn’t a cure, but it’s one of the few natural remedies with small-scale clinical evidence suggesting it may help lower testosterone in women with PCOS. A 2010 randomized controlled trial published in Phytotherapy Research showed that women who drank two cups daily for 30 days had measurable hormonal changes, though visible cosmetic improvements (like hair reduction) take much longer.

But before you rush to Amazon, there’s a lot the viral posts don’t tell you. Like, why do some women’s symptoms temporarily worsen? Or why buying the wrong type of mint wastes your money. Let’s separate the science from the social media noise.

Spearmint Tea for PCOS: What the Studies Actually Show

Understanding Hyperandrogenism in PCOS

PCOS affects 6-12% of women of reproductive age. The most visible symptoms, like stubborn jawline acne, extra facial hair, and hair loss on the scalp, all come from having too much free testosterone.

Normally, your ovaries make small amounts of male hormones (androgens). In PCOS, two things happen: insulin resistance causes your ovaries to make too much testosterone, and high insulin lowers SHBG (Sex Hormone Binding Globulin), the protein that usually keeps testosterone in check.

The result is more free, active testosterone in your body. This hormone attaches to receptors in your skin and hair follicles, increases oil production (which can cause cystic acne), and turns soft peach fuzz into thicker, darker hair.

The Clinical Evidence: Small Studies, Real Hormonal Changes

Small studies in people found that spearmint tea lowered free testosterone and affected other hormones like LH, FSH, and sometimes estradiol. This means you should think of it as a hormone-active remedy, not just a simple tea.

A 2007 Turkish study first demonstrated this effect. Twenty-one women with hirsutism drank two cups of spearmint tea daily for just five days during their follicular phase. Blood tests showed a significant drop in free testosterone levels in less than a week.

But the gold-standard study came in 2010 from researcher Paul Grant in the UK. Forty-two women with PCOS and hirsutism were randomized to drink either spearmint tea or a chamomile tea control (not necessarily inert) twice daily for 30 days. Results:

Free testosterone dropped significantly (the study reported statistically significant reductions).
Total testosterone also decreased in the spearmint group.
Subjective improvements in quality of life related to unwanted hair growth.
But: Objective hair measurements (Ferriman-Gallwey scores) didn’t change in 30 days.

Note: Chamomile isn’t a perfect placebo; some studies suggest it can influence hormone markers in PCOS, so the true effect size vs an inert control is uncertain.

This is important to remember. Even if hormone levels drop, it takes months for existing hair to thin and slow down. Hair follicles go through cycles that last 3-6 months.

Spearmint vs. Peppermint: Why the Difference Matters

Many people make a common mistake by buying “mint tea” from the grocery store and then wonder why they don’t see any results.

Peppermint (Mentha x piperita) is a hybrid plant high in menthol, a cooling compound that helps digestion and freshens breath. The clinical evidence for androgen changes is on spearmint (Mentha spicata). Peppermint is studied mainly for GI effects, not PCOS-related hyperandrogenism.

Spearmint (Mentha spicata) has a different chemical profile. Carvone is typically the dominant compound (often reported roughly ~40-80% in essential oil analyses, depending on the plant/region), while menthol is minimal.

If your tea tastes very cooling or reminds you of toothpaste, it’s probably peppermint. Spearmint has a milder, slightly sweet flavor and doesn’t have that icy feeling. Check the label for the botanical name: look for Mentha spicata, not Mentha piperita.

What to Expect: The Timeline Nobody Talks About

Hormonal Acne: 1-3 Months for Visible Improvement

Hormonal acne, which causes deep and painful cysts along the jawline and chin, may improve with spearmint tea, but it takes time.

Week 1-2: Some women notice reduced inflammation. Others report temporary worsening (more on this below).

Month 1 (One full cycle): Testosterone levels may have dropped measurably in blood tests. Existing cysts start healing. New breakouts may be smaller.

Months 2-3: If spearmint is working for you, this is when you’d see more obvious clearing. Your skin’s oil balance stabilizes.

The process is simple. When you have less free testosterone, your oil glands get fewer signals to make extra oil. Less oil can lead to fewer clogged pores.

Hirsutism (Excess Facial/Body Hair): 3-6 Months Minimum

It’s important to manage your expectations. Spearmint may slow new hair growth and thin existing coarse hair, but it will not remove hair overnight.

Month 1: You may notice you’re shaving or plucking less frequently. New growth comes in finer.

Months 3-6: Some women report a visible reduction in the density and coarseness of facial hair. Existing dark hairs thin and lighten. Some vellus (peach fuzz) hairs may never fully transition to terminal hair.

Many women use spearmint tea along with hair removal methods like laser or electrolysis for quicker results. The tea may help stop new unwanted hair from growing, while laser treatments remove existing hair.

Menstrual Cycle Changes

Since spearmint can affect LH and FSH, your menstrual cycle might change during the first one or two months. Some women who don’t usually ovulate may get their first period in months, while others with regular cycles might notice spotting or small delays.

This may be your hormones adjusting. If changes in your cycle last more than two cycles or you are concerned, talk to your healthcare provider.

Side Effects the Pretty TikToks Don’t Show

Temporary Acne Flares: Is This “Purging”?

Some people notice a temporary flare-up in the first few weeks. This is based on personal reports and not well-studied. If it is severe or lasts more than about 8 weeks, stop and talk to a clinician.

Retinoids and acids speed up skin cell turnover, but spearmint works by changing hormone levels. Some people report a temporary flare, but this is anecdotal. If your symptoms are severe, getting worse, or not better after about 8 weeks, stop and talk to a clinician or dermatologist.

It can be frustrating to drink tea for acne and see it get worse at first. However, this phase usually does not last long. By weeks 6 to 8, most women who keep going report that their skin improves.

If your acne becomes severe or painful, consider:

Reduce to one cup daily for the first two weeks, then increase.
Pairing spearmint with topical treatments like azelaic acid or niacinamide to manage inflammation.
Consult a dermatologist if breakouts don’t improve after 8 weeks.

Delayed or Irregular Periods

Spearmint can affect LH and FSH, which may temporarily change your cycle. Some women find their periods come 5-7 days later than usual, while others notice spotting in the middle of their cycle.

For women with PCOS who rarely ovulate, this can be a good sign because ovulation may start again. But if you usually have a regular 28-day cycle and it suddenly becomes 35 days, it can feel stressful.

Keep track of your cycles during the first two months. Most women’s cycles return to normal by the third month. If you do not have a period for more than 60 days, stop drinking the tea and see your doctor.

Safety Concerns: Liver, Pregnancy, Reflux, and Drug Interactions

High doses of spearmint, especially in concentrated oils or too many capsules, have caused liver stress in animal studies. For most women with healthy livers, two cups of tea daily is considered safe.

Evidence on reflux is mixed; one study found spearmint didn’t reduce LES pressure, though very high doses may cause irritation in some people.

Pregnancy and breastfeeding: Do not drink spearmint tea if you are pregnant or trying to get pregnant. While breastfeeding, any type of mint may lower milk supply, so it is not recommended if you are nursing.

Drug interactions: If you take sedatives, anticonvulsants, or hepatotoxic medications (like isotretinoin/Accutane), consult your healthcare provider before adding spearmint.

How to Drink Spearmint Tea for Best Results: The Protocol

Dosage: 2 Cups Daily

The clinical studies used two cups daily (as used in small clinical trials). Split into two servings per day for consistency. This dosing delivered measurable hormonal changes within 30 days.

More is not always better. Drinking three or four cups will not double the results. It only increases the risk of side effects without proven extra benefits.

Brewing Technique: Why Covering Matters

This is a step many people skip, but it could make a difference.

Spearmint’s active compounds (especially carvone) are volatile. Covering while steeping is a reasonable best practice for retaining aroma compounds, but it hasn’t been proven to be a requirement for hormonal effects.

Proper brewing:

Use hot water (near-boiling is fine for dried spearmint).
Add 1 tea bag or 1-2 teaspoons of loose spearmint to your cup.
Pour water over the leaves and cover with a lid or small plate.
Steep for 5-10 minutes while covered.
Remove the tea bag/strain the leaves. Drink warm or let cool.

You can drink it hot or cold, but the initial brewing should be hot to extract the active compounds. If you prefer iced tea, brew hot, then refrigerate.

Timing: When to Drink

Morning dose: Supports potential hormonal effects during your follicular phase (first half of your cycle).

Evening dose: Some people find mint tea calming and enjoy it as a caffeine-free drink in the evening. The effects of spearmint tea on cortisol are not well known. It can be part of your bedtime tea routine.

Like many teas, polyphenols can reduce non-heme iron absorption in some situations, especially when you’re iron-deficient and separated by ~1-2 hours from meals.

Best Spearmint Tea Brands for PCOS (2026 Buyer’s Guide)

Not all spearmint teas are created equal. Quality varies based on sourcing, organic certification, and contamination screening. Here are three widely available options across price tiers (verify ingredients/certifications on current listings).

Note: We do not earn money from these product recommendations. These are our genuine suggestions based on quality and value.

Budget Tier (Bulk Buying): FGO Organic Spearmint Tea

Typical cost per cup: Low
Why it’s worth considering: If you’re committing to the 3-6 month protocol, buying in bulk can save you money. FGO uses 100% organic spearmint leaves. The company states its bags are plant-based; verify materials on the current listing.

The flavor is clean and suitable for daily use at this price point.

Best for: Budget-conscious users who plan to drink spearmint long-term.

Where to find it: Widely available on Amazon and health retailers, search “FGO Organic Spearmint Tea.” Prices vary by country and retailer.

Mid-Range (Widely Available): Traditional Medicinals Organic Spearmint

Typical cost per cup: Medium
Why it’s popular: This organic tea is easy to find and is often recommended by herbalists and nutritionists. The company says it is USDA Organic and shares quality and testing information. Check the product listing for current certifications.

The tea bags are unbleached, and the flavor is clean and strong, without any grassy or musty taste that can mean the leaves are old or low quality. If you are new to spearmint tea for PCOS, this is a good place to start.

Best for: Beginners wanting a reliable, accessible brand.

Where to find it: You can buy this tea at many health food stores and online. Search for “Traditional Medicinals Organic Spearmint.” Prices depend on your country and the store.

Premium Tier (Purity Focus): Pique Tea Mint Herbal Crystals

Typical cost per cup: High
Why it’s premium: The company says it uses third-party testing for pesticides, mold toxins, and heavy metals. Pique also uses a special cold-brew crystallization process.

The crystals dissolve right away in cold or hot water, making them convenient for travel or for making iced spearmint tea without brewing. Using loose-leaf tea with a good strainer can also help you avoid some materials found in tea bags, since research has found microplastics in some types.

Best for: People seeking brands with detailed purity claims or who want instant convenience.

Where to find it: You can buy this on the Pique Tea website or by searching for “Pique Mint Herbal Crystals” online. Prices depend on your country and the store.

What to Avoid

Generic “Mint Tea” blends: Most grocery store mint teas are either peppermint or a mix of peppermint and spearmint. For best results, you need 100% Mentha spicata.

Non-organic brands: Herbs can have pesticide residues or other contaminants, depending on where they come from. Choosing organic or third-party tested brands is a good idea.

Spearmint capsules (unless necessary): Capsules are convenient, but you miss out on the hydration from tea and they can cause “minty burping” or reflux. The way your body absorbs the active compounds may also be different from hot tea. Only use capsules if you really cannot handle the taste of the tea.

Stacking Strategies: What to Combine with Spearmint

Spearmint tea helps lower androgens, but PCOS affects many systems in the body. Here are some ways to create a more complete approach:

Green Tea: The Insulin Sensitivity Booster

PCOS is not just about testosterone. Insulin resistance also leads to higher androgen levels. Green tea may help support metabolic health for some people. If you try it, use it as an optional addition and pay attention to your iron levels and caffeine sensitivity.

How to combine: Brew one cup of green tea and one cup of spearmint tea separately. Mix them together or drink them one at a time. Some women prefer alternating days.

Bonus: Green tea’s caffeine content helps with energy and focus. Learn more about green tea benefits.

Caution: Drinking more than three cups of green tea a day can lower iron absorption. Try to drink your tea at a different time than your meals.

Inositol: The Clinical Partner

Myo-inositol and D-chiro-inositol are vitamin-like compounds that have been studied for improving ovulation, lowering androgens, and regulating cycles in women with PCOS. When you combine them with spearmint, you target both high androgen levels and insulin resistance.

Typical dosage: 2000mg myo-inositol + 50mg D-chiro-inositol twice daily (brands like Ovasitol or Wholesome Story).

This combination is supported by multiple clinical trials and is often recommended by reproductive endocrinologists.

Zinc: The Acne Support

If hormonal acne is your primary concern, adding zinc (15-30mg daily) may help. Zinc reduces inflammation, regulates oil production, and supports immune function.

Choose chelated forms such as zinc picolinate or zinc glycinate, as they are absorbed better by the body.

Who Should NOT Drink Spearmint Tea

While generally safe at normal doses, spearmint is contraindicated for certain groups:

Pregnant or trying to conceive: Hormonal effects could theoretically affect fetal development.
Breastfeeding mothers: Mint may suppress milk production in some women.
Liver or kidney disease: High doses may stress these organs. Consult your doctor first.
Taking sedative medications: Spearmint has mild sedative properties and may enhance drowsiness.
Severe iron deficiency: Polyphenols inhibit iron absorption. Space tea 1-2 hours from meals and supplements.

If you experience severe side effects (rash, difficulty breathing, intense nausea), discontinue immediately and seek medical attention.

Real Talk: Will Spearmint Tea “Fix” Your PCOS?

To be honest, no single remedy can fix PCOS. It is a complex hormone disorder that needs a combination of diet, exercise, sometimes medication, and lifestyle changes.

But here’s what spearmint tea may offer: It’s one of the few natural remedies with small-scale clinical evidence suggesting it can lower free testosterone with minimal side effects when used correctly. For some women, it’s part of the toolkit. For others, it doesn’t noticeably help.

Spearmint tea will not replace metformin if you need it, and it cannot reverse severe insulin resistance by itself. But as part of a complete PCOS management plan, along with healthy eating, exercise, stress management, and possibly supplements like inositol, spearmint tea is worth considering if you want natural, evidence-based options.

Consistency is important. Drink two cups daily, brewed correctly, for at least three months. One week is not enough, and it should not be just when you remember. Track your symptoms, take photos if you are watching for skin or hair changes, and give it a fair try.

Frequently Asked Questions

How long does spearmint tea take to work for hormonal acne?

Blood testosterone levels may drop within 5-30 days in small studies, but visible skin improvements typically require 1-3 months. Be patient through the first cycle; many women see clearer effects by month two if the tea works for them.

Can I drink spearmint tea cold, or does it have to be hot?

You can drink it cold, but the initial brewing should be hot to extract the active compounds like carvone and rosmarinic acid. Brew it hot, cover the cup during steeping, then refrigerate if you prefer iced tea. Cold-brew methods (such as steeping in cold water overnight) are less effective for therapeutic use.

Is spearmint tea “purging” real, or is my acne just getting worse?

Some people report temporary breakouts in the first few weeks. This is anecdotal and not well-studied clinically. If it’s severe or doesn’t improve by 8 weeks, stop and consult a dermatologist.

Can I take spearmint capsules instead of drinking tea?

Capsules are an option if you can’t tolerate the taste, but hot tea infusion may provide better delivery of volatile oils. Capsules can also cause gastric reflux (“minty burps”). If you choose capsules, look for reputable brands and follow dosing instructions carefully.

Should I drink spearmint tea during my period, or only certain weeks?

The clinical studies used continuous daily dosing throughout the entire cycle, two cups daily, every day. Some practitioners recommend cycling on and off monthly, but there’s no strong evidence that this is necessary or superior to consistent use.

Can men drink spearmint tea, or will it lower their testosterone too much?

Limited research exists on men. One small study suggested spearmint may reduce testosterone in men, which could affect libido or other functions. Men should avoid therapeutic doses (2+ cups daily) unless specifically advised by a healthcare provider.
