Does Peppermint Tea Actually Help With Hormonal Acne? What Research Shows
Key Takeaways
- Peppermint (Mentha piperita) and spearmint (Mentha spicata) are related but chemically distinct mint species.
- A 2010 trial found spearmint tea, taken twice daily for 30 days, lowered free testosterone in women with PCOS.
- A 2007 study linked five days of spearmint tea to shifted androgen markers in women with hirsutism.
- No published trial has tested peppermint tea's effect on androgen levels the way spearmint has been tested.
- Two cups a day was the dose used in both spearmint trials, not an established peppermint protocol.
Most of the hormonal-acne tea research was done on spearmint, not peppermint, two related but chemically different mint species. Two small trials found that spearmint tea, taken about twice daily, was linked to lower free testosterone in women with PCOS or hirsutism. Peppermint tea itself has not been tested the same way.
Is Peppermint the Same Plant as Spearmint?
No. Peppermint (Mentha piperita) is a natural hybrid of watermint and spearmint, while spearmint (Mentha spicata) is its own separate species. Peppermint's essential oil is dominated by menthol; spearmint's is dominated by carvone. That distinction matters because the human studies behind the mint-tea-for-hormones claim used spearmint, not peppermint.
Peppermint and spearmint are both in the genus Mentha, but they are not interchangeable. Peppermint (Mentha piperita) is actually a hybrid that arose from watermint and spearmint, while spearmint (Mentha spicata) has remained its own distinct species through centuries of cultivation.
The practical difference shows up in the essential oil. Peppermint leaves are rich in menthol, the compound behind that cooling sensation. Spearmint leaves are richer in carvone, a different aromatic compound entirely. Flavor, aroma, and, as far as researchers have tested it, biological activity all trace back to that split.
If you started researching whether peppermint tea helps with acne because you read that mint tea can affect hormones, it's worth knowing upfront: the specific research behind that idea was conducted on spearmint leaves, not peppermint.
What Did the Spearmint-and-Hormones Research Actually Find?
Two small randomized trials tested spearmint tea in women with PCOS or hirsutism. A 2010 trial had participants drink spearmint tea twice daily for 30 days and found a significant drop in free testosterone, with total testosterone unchanged. A 2007 trial found similar hormone shifts after just five days.
The most-cited study is a 2010 randomized controlled trial by researcher Paul Grant, published in Phytotherapy Research. Women with polycystic ovary syndrome (PCOS) drank spearmint tea twice a day for 30 days. Free testosterone dropped significantly by the end of the trial, while total testosterone did not change in a statistically meaningful way.
An earlier 2007 trial by Akdoğan and colleagues, also in Phytotherapy Research, gave spearmint tea twice daily to women with hirsutism (excess hair growth linked to androgen levels) for five days. Hormone markers shifted in a similar direction, and participants reported some subjective improvement.
Both trials measured hormone levels and hirsutism scores, not acne lesions directly. The link to acne is inferred through the shared androgen pathway, not tested as a standalone outcome.
Both studies were small, short, and specific to women already diagnosed with PCOS or hirsutism, which matters for anyone trying to extrapolate the findings to hormonal acne generally.
What Does Peppermint Tea's Own Research Show?
Peppermint's best-documented research is about digestion, not hormones. Health authorities like NCCIH note peppermint oil, usually in enteric-coated capsules, has been studied for digestive comfort. No published trial has measured peppermint tea's effect on testosterone or other androgens the way the spearmint studies did.
Peppermint has its own research base, it's just aimed at a different system. The National Center for Complementary and Integrative Health (NCCIH) notes that peppermint oil, typically taken in enteric-coated capsules rather than as tea, is the form most studied, and that research centers on digestive comfort.
That digestive angle is a separate topic from hormones (and connects to the broader gut-skin conversation some readers are already researching elsewhere). For hormonal acne specifically, no equivalent human trial has tested peppermint tea's effect on testosterone, DHEA-S, or any other androgen marker.
In other words, peppermint tea isn't unproven because someone disproved it. It simply hasn't been tested for this particular question yet.
Does Swapping Peppermint for Spearmint Make Sense?
Not automatically. Because peppermint and spearmint differ in their dominant compounds, menthol versus carvone, a hormonal effect measured in spearmint can't be assumed to carry over to peppermint. Some commercial mint tea blends mix both leaves, so matching the studied protocol means checking the label for Mentha spicata specifically.
It's tempting to assume the two teas are basically interchangeable, but the researchers didn't test it that way, and the two plants' chemistry genuinely differs. Carvone-dominant spearmint and menthol-dominant peppermint could plausibly behave differently once consumed, though that exact comparison hasn't been studied head-to-head.
- Check the ingredient label for Mentha spicata or spearmint if you want the studied plant, not just a generic mint tea.
- Loose-leaf blends and tea bags sometimes combine peppermint and spearmint together, so read past the front-of-box name.
- Peppermint-only tea is still a reasonable, low-risk beverage; it just isn't the one the hormone studies used.
If your goal is specifically to mirror what the research tested, spearmint, not peppermint, is the leaf to look for.
What to Do If You Want to Try Mint Tea for Hormonal Acne
Start by choosing true spearmint (Mentha spicata), the plant the studies used, and steep about two cups a day, the dose both trials tested. Track breakouts against your cycle for several weeks before judging results, and loop in a doctor if you're on hormonal medication or trying to conceive.
If this research made you curious enough to try it yourself, a few concrete steps make the experiment worth running:
- Choose the right leaf. Look for spearmint or Mentha spicata specifically, not a generic mint blend.
- Match the studied dose. Both trials used about two cups a day, one in the morning and one in the evening.
- Give it real time. The published trials ran anywhere from five days to a full month; a single week won't tell you much either way.
- Track what you can see. Photograph your skin weekly in the same light, and log where you are in your cycle alongside sleep, stress, and diet.
- Loop in a professional if you're on hormonal birth control, trying to conceive, or managing PCOS, since spearmint's hormone effects haven't been studied in every population.
Mint tea is one habit in a bigger picture. If you're already tightening up your routine, a daily supplement built to support the body's natural detoxification pathways, like Max Detox, can sit alongside habits like this rather than replace any of them.
The Bottom Line on Peppermint Tea and Hormonal Acne
Peppermint tea is not the plant behind the hormonal-acne research some readers cite; spearmint is. The spearmint trials are small, short, and specific to PCOS and hirsutism, not acne itself. Peppermint remains a pleasant, low-risk tea, just not one with its own hormone data yet.
If you came here searching for whether peppermint tea helps with acne, the honest answer is that the research trail leads to a different plant. Spearmint, not peppermint, is what the two available human trials tested, and even those studied hormone markers and hirsutism, not acne breakouts directly.
That doesn't make peppermint tea pointless. It's a caffeine-free, low-risk habit with its own separate research base around digestive comfort. It just isn't the ingredient to reach for if hormonal support is specifically your goal.
Pair whichever mint tea you enjoy with the basics that already have a broader evidence base: consistent sleep, a stable skincare routine, and, if you want extra support for your body's natural detox pathways, a daily habit like Max Detox alongside it.

Frequently Asked Questions
Is peppermint tea the same as spearmint tea?
No. Peppermint (Mentha piperita) and spearmint (Mentha spicata) are related but separate mint species with different dominant aromatic compounds, menthol in peppermint, carvone in spearmint. The available hormonal-acne research specifically used spearmint tea and leaves, not peppermint, so the two shouldn't be treated as interchangeable.
How many cups of spearmint tea did the studies use?
Both available trials used about two cups of spearmint tea a day. A 2010 study ran that dose for 30 days in women with PCOS, while a 2007 study used the same twice-daily pattern for five days in women with hirsutism.
Can peppermint tea affect hormones the way spearmint might?
It's not established either way. Peppermint's dominant compound, menthol, differs from spearmint's carvone, and no published trial has tested peppermint tea against androgen levels. Until that research exists, it's more accurate to say peppermint's hormonal effects are simply unstudied, not confirmed or ruled out.
Is it safe to drink mint tea daily alongside a skincare routine?
For most healthy adults, a couple of cups of peppermint or spearmint tea a day is considered a low-risk, caffeine-free habit. People who are pregnant, on hormonal medication, or managing a thyroid or hormone condition should check with a doctor before making it a daily routine.
Does mint tea replace a hormonal acne treatment plan?
No single tea replaces a full skin or hormone care plan. Mint tea, spearmint in particular, is best viewed as one small supporting habit alongside sleep, stress management, and a consistent skincare routine, not a stand-alone fix for hormonal acne breakouts.
