How Does Spearmint Tea Work

Updated for 2025 | Evidence-based | ~3,200 words

---

Quick Answer: Spearmint tea works primarily by reducing free testosterone levels in the body through its natural anti-androgenic compounds. Two clinical studies — one from 2007 and one published in Advances in Therapy — show it can meaningfully lower androgens in women, which is why it's used for hormonal acne, PCOS symptoms, and unwanted hair growth. But the research has real limitations, and understanding those matters before you start.

What Is Spearmint Tea, Really?

Spearmint tea is an herbal infusion made from the dried or fresh leaves of Mentha spicata, a plant in the mint family. Unlike peppermint, which contains high levels of menthol and delivers that intense, sharp cooling sensation, spearmint has a softer, sweeter flavor profile with significantly lower menthol content.

But what makes spearmint genuinely interesting — at least from a health standpoint — isn't the flavor. It's the chemical compounds inside the leaves.

Spearmint contains:

• Rosmarinic acid — a polyphenol with documented antioxidant and anti-inflammatory properties
• Flavonoids — plant-based compounds associated with reduced oxidative stress
• Carvone — the primary aromatic compound responsible for spearmint's distinct smell
• Limonene, myrcene, and other terpenes — with mild biological activity
• Phytosterols — plant sterols that may interact with hormone pathways

According to the Cleveland Clinic, spearmint's rosmarinic acid content and flavonoid concentration are two of the main reasons the tea has drawn scientific interest beyond simple digestion relief.[5] These compounds appear to do real biological work — and one of those jobs is interfering with how androgens (male hormones) function in the body.

That hormone connection is the heart of almost every claim you've read about spearmint tea.

The Core Mechanism: How Does Spearmint Tea Work?

So — how does spearmint tea work at a biological level?

The most evidence-supported mechanism is anti-androgenic activity. Androgens are a group of hormones — testosterone being the most well-known — that both men and women produce. In women, abnormally elevated androgen levels are associated with:

• Hormonal acne (especially along the jawline and chin)
• Hirsutism (excess facial and body hair)
• Irregular periods
• PCOS (polycystic ovary syndrome)
• Oily skin

Spearmint appears to reduce the amount of free testosterone circulating in the bloodstream. Free testosterone is the biologically active form — it's unbound to proteins, which means it can directly interact with tissues like skin, hair follicles, and sebaceous (oil) glands.

When free testosterone levels drop, several things can happen:

1. Sebaceous glands produce less sebum (oil)
2. Hair follicles become less sensitive to androgenic signals
3. The hormonal cascade that triggers inflammatory acne is reduced

The proposed mechanism isn't that spearmint "blocks" testosterone the way pharmaceutical anti-androgens do. Instead, researchers believe spearmint's phytochemicals may:

• Inhibit 5-alpha reductase, the enzyme that converts testosterone into its more potent form, DHT (dihydrotestosterone)
• Compete with androgens at receptor sites, reducing how effectively testosterone signals reach target tissues
• Influence the hypothalamic-pituitary-ovarian (HPO) axis, altering how the brain signals the ovaries to produce hormones

This last point is supported by the observation that spearmint consumption appears to increase luteinizing hormone (LH) and follicle-stimulating hormone (FSH) while simultaneously lowering free testosterone — a pattern suggesting upstream hormonal influence rather than simple receptor blocking.

How Does Spearmint Tea Work Explained Simply

If the mechanism above felt dense, here's how does spearmint tea work explained simply:

Think of androgens like testosterone as a volume dial on your skin's oil production and hair growth settings. In some people — especially those with PCOS or hormonal acne — that dial is turned up too high.

Spearmint tea appears to gently nudge that dial down.

It doesn't reset it to zero. It doesn't work as fast or as powerfully as prescription medication. But for people whose dial is just slightly too high, that gentle nudge can make a noticeable difference over weeks or months.

Here's an even simpler chain of events:

1. You drink spearmint tea (typically 2 cups per day)
2. Compounds in the tea enter your bloodstream
3. Those compounds interfere with how testosterone behaves in your body
4. Your skin produces slightly less oil
5. Hair follicles receive weaker androgenic signals
6. Over time: fewer hormonal breakouts, potentially reduced facial hair

The key word throughout is "gently." Spearmint tea is not a hormone medication. It's a plant-based intervention with modest but real effects for specific people under specific hormonal conditions.

How Does Spearmint Tea Work: The Research and Clinical Studies

When it comes to how does spearmint tea work research, it's important to be upfront: the clinical evidence base is real but limited. Here's what the studies actually say.

The Landmark 2007 Phytotherapy Research Study

The foundational piece of evidence comes from a study published in Phytotherapy Research in 2007. Researchers gave women diagnosed with hirsutism (excess hair growth linked to elevated androgens) either spearmint tea or chamomile tea for five days.

The results were striking for such a short intervention:

• Free testosterone decreased significantly in the spearmint group
• Luteinizing hormone (LH) increased in the spearmint group
• Follicle-stimulating hormone (FSH) also increased
• No significant change was seen in the chamomile (control) group

The rise in LH and FSH alongside the drop in free testosterone suggests spearmint wasn't simply blocking testosterone at the tissue level — it appeared to be influencing the hormonal signaling axis higher up, at the brain-pituitary-ovary communication level.

This study is cited by Healthline, the Cleveland Clinic, and WebMD as the primary evidence for spearmint's anti-androgenic claims — which tells you both how significant the finding was and how limited subsequent research has been.[1][5][7]

The Advances in Therapy Study

A later study published in Advances in Therapy built on this foundation, examining women with PCOS who consumed spearmint tea regularly. This study reported improvements in follicular hormone levels and reduced androgenic effects over time, supporting the earlier findings that spearmint can influence hormone levels beyond a single short-term experiment.

This is important because it moved the evidence from "interesting short-term signal" to "potentially meaningful for PCOS management."

What the Research Has NOT Shown

Being thorough about how does spearmint tea work clinical studies means being honest about the gaps:

• No large-scale, randomized controlled trials (RCTs) in diverse populations
• No direct clinical trial specifically on acne (the acne connection is inferred from hormone research)
• No 2024–2026 primary research has emerged — the field has not produced major new human trials recently
• Short study durations (five days is not long enough to draw conclusions about skin changes)
• Small sample sizes in most existing work
• No established dosage standard supported by clinical evidence

The honest assessment: spearmint tea has a biologically plausible mechanism and early-stage clinical support, but it has not been studied with the rigor required to make it a formal medical recommendation.

Dermatologist Opinion on Spearmint Tea

What does how does spearmint tea work dermatologist opinion actually look like in practice?

The dermatology community tends to fall into three camps on this:

Camp 1: Cautiously optimistic Some dermatologists, particularly those with an interest in integrative approaches, acknowledge the hormone research and consider spearmint tea a reasonable low-risk adjunct for patients with mild to moderate hormonal acne who want to explore natural options alongside (not instead of) clinical treatment.

Camp 2: Skeptical but not dismissive Many mainstream dermatologists are skeptical of claims that two cups of tea can meaningfully change hormonal acne outcomes. They point out that the clinical trials are small, short, and focused on free testosterone in hirsutism — not acne outcomes specifically. They're reluctant to recommend something without direct acne trial data.

Camp 3: Indifferent Some simply don't bring it up either way, focusing conversation on proven treatments: topical retinoids, benzoyl peroxide, antibiotics, oral contraceptives, or spironolactone for hormonal cases.

The common thread across all three perspectives: no dermatologist recommends replacing medical treatment with spearmint tea alone for moderate to severe hormonal acne or PCOS-related symptoms.

Where spearmint tea earns dermatologist acknowledgment is as a low-risk, potentially supportive habit — especially for people who are managing mild symptoms or who are already on a clinical treatment and want additional lifestyle support.

It's also worth noting that the anti-inflammatory properties of rosmarinic acid, highlighted by the Cleveland Clinic, are relevant here.[5] Inflammation is a key driver of acne, and reducing oxidative stress through diet and beverages is something most dermatologists broadly support.

What Reddit Discussions Actually Reveal

No guide on how does spearmint tea work reddit discussion would be complete without acknowledging what the actual anecdotal evidence pool looks like — because Reddit, particularly communities like r/SkincareAddiction and r/PCOS, contains thousands of first-person accounts.

What Reddit users commonly report:

• Positive results typically start appearing after 4–8 weeks of consistent twice-daily consumption
• Most people who report success describe it as "subtle but real" — not dramatic overnight change
• The most consistent positive reports come from women with confirmed or suspected hormonal acne (cyclic breakouts, jawline/chin location)
• Some users report their acne worsened slightly in the first 2–3 weeks before improving — possibly a hormonal adjustment period
• A minority report no effect whatsoever, even after months

What Reddit discussions reveal about failure cases:

• People expecting fast results (under 2 weeks) are almost universally disappointed
• Those with primarily non-hormonal acne (clogged pores, diet-related, stress-related) rarely report improvement
• Some users tried it and switched to spearmint supplements (capsules) after finding the tea inconvenient or too mild

The Reddit consensus, honestly:

It works for some people. Specifically: women with hormonal acne who are patient enough to give it 2–3 months. It's not a miracle. It's not useless. It's a mild, low-risk intervention that earns loyalty from a subset of people for whom androgens are the core issue.

That's a realistic takeaway that no supplement marketing will tell you directly.

Spearmint Tea for Hormonal Acne, PCOS, and Hirsutism

Let's address the three most common specific use cases:

Hormonal Acne

The connection between spearmint tea and hormonal acne is indirect but logical. The studies show reduced free testosterone. Elevated free testosterone drives sebum overproduction. Excess sebum contributes to clogged pores and inflammatory acne. Therefore: lower testosterone → less oil → fewer breakouts.

No study has directly tested "spearmint tea vs. placebo for acne outcomes" with skin as the primary endpoint. That gap matters scientifically, but the mechanistic chain is coherent.

Best candidates: Women who break out cyclically (especially before periods), along the jawline and chin, and who have had androgen levels confirmed as elevated or borderline.

PCOS

PCOS (polycystic ovary syndrome) is characterized in part by elevated androgens, irregular cycles, and multiple small ovarian cysts. The Advances in Therapy study specifically addressed PCOS-related hormonal profiles and found improvement with spearmint tea.

For PCOS, spearmint tea is most realistically framed as one component of a broader management strategy — not a standalone treatment. Diet, exercise, stress management, and (for many women) medication remain the primary interventions.

Hirsutism

This is actually where the most direct evidence exists — the 2007 Phytotherapy Research study was specifically conducted in women with hirsutism. The reduction in free testosterone is directly relevant to the hormonal signaling that drives excess hair growth.

However, reducing testosterone levels doesn't automatically cause existing hair to fall out immediately. Hair follicle change takes time — typically months of consistent hormonal shift before visible reduction in hair growth rate.

How Long Does It Take to Work? Before and After Expectations

Understanding how does spearmint tea work before and after requires realistic expectation-setting.

| Timeframe | What You Might Notice | |-----------|----------------------| | Days 1–7 | Nothing measurable. Hormone levels may begin shifting, but no visible change. | | Weeks 2–4 | Some users notice slightly less oiliness. Others notice nothing yet. | | Weeks 4–8 | The window where early adopters start reporting fewer breakouts or slower hair regrowth. | | Months 2–3 | The most commonly cited "turning point" in anecdotal reports. | | Months 3–6 | Maximum effect territory for those who respond positively. |

Key factors that influence timing:

• How elevated your baseline androgen levels are
• Whether hormonal acne is truly the primary driver of your skin issues
• Consistency of consumption (skipping days matters)
• Other hormonal factors at play (stress, birth control, cycle phase)

A realistic "before and after" picture for a good responder:

• Before: Cyclic breakouts 1–2 weeks before period, jawline cysts, oily T-zone, possibly some fine chin hairs
• After (3 months): Fewer pre-period breakouts, slightly less oiliness, minor reduction in skin sensitivity to hormonal fluctuation

Not a skin transformation. A meaningful improvement in a specific type of hormonally-driven skin behavior.

Pros and Cons: The Honest Breakdown

Here is how does spearmint tea work pros and cons, laid out without bias:

✅ Pros

• Clinically supported anti-androgenic activity — the hormone research is real, even if limited
• Low cost — loose leaf spearmint or tea bags are inexpensive and widely available
• Low risk — for most healthy adults, two cups daily is safe
• Additional benefits — antioxidant and anti-inflammatory effects from rosmarinic acid and flavonoids
• No prescription required — accessible as a first step before pursuing medical options
• Digestive benefits — traditional use for IBS, bloating, and nausea has some support
• Memory support — WebMD notes that spearmint extract has been associated with a 15% improvement in memory in older adults with memory concerns, though this relates to extract rather than tea specifically[7]

❌ Cons

• Evidence is limited — small studies, short durations, no direct acne RCTs
• Slow to work — requires months of consistency before meaningful assessment
• Not for everyone — only likely effective where androgens are genuinely elevated or a contributing factor
• Not a replacement for medicine — won't substitute for spironolactone, oral contraceptives, or prescription retinoids in moderate-severe cases
• Safety concerns for some — may be problematic during pregnancy or for those with certain hormonal conditions (see below)
• Highly variable response — a significant portion of users report no benefit at all
• Taste fatigue — drinking the same herbal tea twice daily for months can become monotonous

Is Spearmint Tea Safe? Side Effects and Who Should Avoid It

For most healthy adults, spearmint tea at 1–2 cups per day is considered safe. However, there are real considerations:

Potential Side Effects

• Nausea — particularly when consumed on an empty stomach
• Heartburn — mint family plants can relax the lower esophageal sphincter in sensitive individuals
• Hormonal disruption in men — the anti-androgenic mechanism that makes spearmint useful for women with elevated androgens is precisely why men should be cautious; regular consumption could theoretically reduce testosterone meaningfully in men
• Possible liver concerns at high doses — animal studies have shown liver enzyme changes at very high spearmint extract doses; this has not been replicated in normal tea consumption amounts but is worth noting

Who Should Approach with Caution or Avoid

• Pregnant women — spearmint has been used historically as an emmenagogue (stimulating menstrual flow), and its effects on pregnancy aren't well-studied
• Breastfeeding women — insufficient safety data
• Men — the testosterone-lowering effect, while mild, is not beneficial for most men
• Women with estrogen-dominant hormone profiles — reducing androgens further in someone who is already low may not be appropriate
• Anyone on hormonal medication — possible interactions with birth control, hormone therapy, or fertility medications; consult a healthcare provider

The safe approach: If you have a diagnosed hormonal condition, discuss spearmint tea with your doctor or endocrinologist before making it a daily habit. For otherwise healthy women exploring it for mild hormonal acne, the risk profile is generally low.

Spearmint vs. Peppermint Tea: Which One Works Better?

This comparison comes up constantly, and it matters.

| Feature | Spearmint | Peppermint | |---------|-----------|------------| | Menthol content | Low (~0.5%) | High (~40%) | | Anti-androgenic evidence | Yes — multiple studies | Weak/limited | | Anti-inflammatory properties | Yes (rosmarinic acid) | Moderate | | Flavor | Sweet, mild | Sharp, cooling | | Use for hormonal acne/PCOS | Supported | Not well-supported | | Digestive benefits | Yes | Yes (stronger) |

For hormonal purposes: spearmint wins clearly. The clinical studies on testosterone reduction used spearmint specifically, not peppermint. Peppermint's high menthol content gives it different (and better-studied) digestive benefits, but it does not carry the same anti-androgenic research record.

If you've been drinking peppermint tea hoping for hormonal acne benefits, you may want to switch.

How to Use Spearmint Tea for Beginners

If you're new to all of this, here's the complete how does spearmint tea work for beginners practical guide:

What to Buy

• Loose leaf spearmint from a reputable herbalist or health food store (stronger, fresher)
• Spearmint tea bags — brands like Traditional Medicinals, Heather's Tummy Teas, or Alvita are commonly used
• Look for organic where possible to minimize pesticide residue

How to Brew It

1. Boil fresh water and let it cool slightly (90–95°C / 195–200°F is ideal — not quite a rolling boil)
2. Use 1 teaspoon of loose leaf OR 1 tea bag per cup
3. Steep for 5–7 minutes (longer steep = stronger phytochemical extraction)
4. Don't add sugar — this is a daily health habit, not a dessert

Dosage

The clinical studies used 2 cups per day. This is the standard starting point. More is not necessarily better and may increase side effect risk.

Suggested timing:

• Morning cup: with or after breakfast
• Evening cup: after dinner or before bed

Consistency Protocol for Beginners

• Week 1–2: Focus on establishing the habit. Don't evaluate results yet.
• Week 3–4: Note any changes in skin oiliness or breakout frequency without placing too much weight on them.
• Month 2: Begin tracking your skin more systematically — photos help.
• Month 3: Make a real assessment of whether the tea is contributing to improvement.

Pairing It with Other Habits

Spearmint tea works best as part of a broader approach, not in isolation:

• Reduce refined sugar and dairy if these are known triggers for you
• Maintain a consistent skincare routine
• Manage stress (cortisol disrupts sex hormones)
• Get adequate sleep (poor sleep elevates androgens)
• Consider discussing spearmint tea with a dermatologist or gynecologist if you're managing PCOS or diagnosed hormonal acne

Frequently Asked Questions

Does spearmint tea lower testosterone in women? Yes — the 2007 Phytotherapy Research study demonstrated a significant reduction in free testosterone in women after just five days of twice-daily spearmint tea. This is the most well-supported finding in the research.

Does spearmint tea lower testosterone in men? Potentially, yes — which is why men are generally advised to avoid regular spearmint tea consumption. The anti-androgenic effect that makes it useful for women with elevated androgens would not be beneficial for most men.

How much spearmint tea should I drink? Two cups per day is what the clinical research used. There's no evidence that drinking more accelerates results, and higher amounts may increase side effect risk.

Is spearmint tea better than spironolactone for hormonal acne? No. Spironolactone is a pharmaceutical anti-androgen with robust clinical evidence for hormonal acne. Spearmint tea is a milder, natural option appropriate for mild symptoms or as an adjunct. They are not equivalent.

Can spearmint tea cure PCOS? No. PCOS is a complex endocrine condition. Spearmint tea may help modulate some androgenic symptoms but does not address the underlying condition and is not a medical treatment.

Can I take spearmint capsules instead of tea? Some people do, especially for convenience. However, most clinical research used tea specifically, and the absorption and phytochemical profile of capsules may differ. Consult a healthcare provider before substituting.

Does spearmint tea interact with birth control? This hasn't been formally studied, but because both influence hormonal balance, there's a theoretical interaction worth discussing with your doctor before combining them.

How does spearmint tea work for facial hair? By reducing free testosterone, spearmint may slow the rate of androgenically-stimulated facial hair growth over time. Don't expect existing hair to disappear — you're working on the hormonal signal, not removing hair. Results, if they occur, take months.

---

Final Verdict

Here is how does spearmint tea work honest: it works through a real, biologically plausible mechanism — reducing free testosterone — that is supported by small but legitimate clinical studies. It is not magic, it is not fast, and it will not work equally well for everyone.

The people most likely to benefit are women with genuinely elevated androgens driving their symptoms — whether that manifests as hormonal acne, hirsutism, or PCOS-related hormonal imbalance. For these individuals, a consistent twice-daily habit of spearmint tea over 2–3 months is a low-cost, low-risk experiment worth trying — ideally alongside (not instead of) other evidence-based interventions.

The people least likely to benefit are those with non-hormonal acne, men seeking skin or hair benefits, or anyone expecting a quick fix.

The research is real but limited. The anecdotal community is large and broadly positive for the right use cases. The safety profile is favorable for most healthy adults. And the cost of trying it — financially and physically — is minimal.

That's the honest answer.

If you're researching this to decide whether to try it: the evidence says there's enough reason to give it a fair, consistent, 3-month trial if you suspect hormonal drivers are at play. Just don't abandon your skincare routine while you wait.
