You’ve probably seen it sitting there on the grocery store shelf, sandwiched between the peppermint and the chamomile. It looks unassuming. It’s just dried leaves in a bag. But honestly, spearmint tea is having a massive moment right now, especially in circles where people are trying to manage their hormones without jumping straight to heavy pharmaceuticals. It isn't just a refreshing drink to sip on a Tuesday afternoon. For a lot of people, it’s basically a tool for survival.
The health benefits of drinking spearmint tea are surprisingly well-documented, even if the mainstream wellness world sometimes ignores them in favor of the latest "superfood" powder. We’re talking about real, peer-reviewed stuff. If you've ever dealt with stubborn hormonal acne or that sluggish, bloated feeling after a heavy meal, this herb might be more relevant to your life than you think.
It’s different from peppermint. That’s the first thing people get wrong. While both are in the Mentha genus, spearmint contains significantly less menthol. This gives it a sweeter, more delicate profile that won't make your eyes water. But beneath that mild flavor is a complex profile of polyphenols and antioxidants like rosmarinic acid.
The Hormonal Connection Most People Miss
The big one. The heavy hitter. If you search for spearmint tea online, you're going to see a lot of talk about PCOS (Polycystic Ovary Syndrome). Why? Because of its anti-androgenic effects. High levels of androgens—like testosterone—in women can lead to things no one wants: excess facial hair growth (hirsutism), thinning hair on the head, and deep, cystic acne that won't quit.
A significant study published in Phytotherapy Research looked at women with PCOS who drank spearmint tea twice a day. The results weren't just "maybe it worked." Researchers found a clear decrease in free testosterone levels and an increase in luteinizing hormone (LH) and follicle-stimulating hormone (FSH) over a 30-day period. It’s rare to see a simple herbal tea move the needle that much on blood work.
It isn't a magic pill. You can't just drink one cup and expect your skin to clear up overnight. Biology is slow. But for those looking for a natural way to nudge their hormones back into balance, the data is actually there. It’s kinda wild how a plant can interact with the endocrine system so specifically.
Digestion and the "Angry Gut" Syndrome
We’ve all been there. You eat something that doesn't quite agree with you, and suddenly you feel like you've swallowed a bowling ball. While peppermint is usually the go-to for stomach issues, the health benefits of drinking spearmint tea for digestion are just as legit, and often gentler for people with sensitive stomachs or acid reflux.

The secret lies in its ability to relax the digestive muscles. It contains a compound called (-)–carvone. This stuff acts as a natural antispasmodic. Basically, it tells your stomach and intestines to stop cramping up.
Think about it this way: when your digestive tract is stressed, it tenses. Spearmint helps it "chill out." This is why it’s often used as a complementary treatment for Irritable Bowel Syndrome (IBS). It helps gas move through the system instead of getting trapped and causing that sharp, stabbing pain we all hate. Plus, it’s caffeine-free. You can drink it at 9 PM and not worry about staring at the ceiling until 3 AM.
Memory and the Brain-Fog Factor
This is a newer area of research, but it’s fascinating. There was a study conducted by Saint Louis University where older adults with age-associated memory impairment took a spearmint extract. They didn't just feel "sharper." Their working memory scores actually improved by about 15%.
Scientists think the high concentration of polyphenols protects the brain from oxidative stress. It’s sort of like putting an antioxidant shield around your neurons. Will it turn you into a genius? No. But if you’re struggling with that mid-afternoon brain fog where you can’t remember why you walked into a room, swapping your third coffee for a spearmint tea might actually help.
Understanding the Antioxidant Load
Antioxidants is a buzzword that gets thrown around a lot. People use it to sell everything from chocolate to face cream. But in spearmint, it’s not just marketing. It’s loaded with limonene, dihydrocarvone, and cineole.
These compounds do the dirty work of neutralizing free radicals. If you’re living in a city with pollution, or you’re stressed out, or you’re just aging (which is all of us), your cells are taking a beating. Spearmint provides a steady supply of the "repair crew" your body needs to keep inflammation down.

High inflammation is linked to everything. Heart disease. Diabetes. Arthritis. By keeping systemic inflammation low through your diet—including what you drink—you’re basically playing the long game for your health.
How Much Do You Actually Need to Drink?
This is where people usually trip up. They drink a cup once a week and wonder why nothing changed. To see the hormonal benefits mentioned in the studies, consistency is the entire point.
Most clinical trials used two cups a day.
Morning and evening.
Steeped for at least 5 to 10 minutes to make sure the essential oils actually get into the water.
If you just dunk the bag for thirty seconds, you're getting flavored water, not medicine. You want that tea to be strong. It should have a bit of a "bite" to it. That’s how you know the active compounds are actually present.
Real Talk: The Side Effects and Limitations
Nothing is perfect. Even tea.
Because spearmint can lower testosterone, men who are trying to build muscle or who already have low testosterone should probably take it easy on the spearmint. It’s not going to cause immediate issues, but long-term, heavy consumption could theoretically impact libido or muscle mass in men.

Also, if you're pregnant or breastfeeding, talk to your doctor. It’s a common herb, but in high "medicinal" doses, we don't have enough long-term data to say it’s 100% fine for everyone in every situation.
And for the love of all things holy, don't use it as a replacement for actual medical treatment if you have a serious condition. Use it as a companion. It’s a tool in the toolbox, not the whole hardware store.
The Best Way to Brew for Maximum Impact
Don't use boiling water. If the water is screaming hot, you might actually degrade some of the more delicate volatile oils. Aim for just under boiling—around 200 degrees Fahrenheit.
- Use two tea bags if you're using store-bought.
- Cover the mug while it steeps. This is crucial. If you don't cover it, those beneficial oils escape with the steam.
- Wait 10 minutes.
- Squeeze the bags before you toss them.
You can drink it hot, but honestly, it’s incredible iced with a little bit of lemon. No sugar needed because spearmint is naturally sweeter than other mint varieties. It has this clean finish that doesn't leave you feeling thirsty like some other drinks do.
The Verdict on Spearmint Tea
Is it a miracle? No. Miracles don't come in boxes of 20 tea bags for four dollars.
But is it a highly effective, scientifically-backed herbal remedy for hormonal acne, bloating, and mild cognitive lag? Absolutely.
The health benefits of drinking spearmint tea are accessible. That’s the best part. You don't need a prescription. You don't need a specialized health food store. You just need a kettle and ten minutes of patience.
If you're dealing with the specific issues we've talked about—especially the PCOS-related symptoms—it is one of the lowest-risk, highest-reward changes you can make to your daily routine. It’s one of those rare times where the "old wives' tale" actually stood up to the scrutiny of a laboratory.
Actionable Next Steps
- Audit Your Cycle: If you’re tracking your hormones for PCOS or acne, start a "Spearmint Log." Drink two cups daily for one full menstrual cycle (30 days) and note changes in skin clarity or hair growth.
- Check the Label: Ensure you are buying Mentha spicata (Spearmint), not a "Mint Medley" which is often mostly peppermint.
- Temperature Control: Stop using a microwave to boil your water. Invest in a simple electric kettle with temperature settings to preserve the rosmarinic acid.
- Pair with Fat: Some of the antioxidants in spearmint are better absorbed when consumed near a meal that contains healthy fats. Try having your cup after a lunch with avocado or olive oil.
- Go Loose Leaf: If you really want the highest concentration of active compounds, buy loose-leaf spearmint. The surface area is larger, and the leaves are usually less processed than what’s in a standard bleached paper tea bag.
