Side Effects Of Spearmint Tea

So there I was, three weeks into my “glow-up” routine, downing three cups of spearmint tea a day like some sort of herbal influencer. My skin was, I swear, starting to look like a filtered Instagram story—poreless, calm, almost annoyingly clear. I was practically patting myself on the back for ditching that $80 face serum. But then, something weird happened. I started feeling… off, like my usual jittery energy had been replaced by this sudden, mellow fog.

And no, it wasn’t just a case of the Monday blues. I’m talking about the kind of fatigue that makes you seriously consider taking a nap in your salad at lunch. That’s when I had my “uh-oh” moment and realized: maybe my new green BFF had a dark side. Let’s get into the side effects of spearmint tea—because, plot twist, even magic potions have a fine print.

The Hormonal Hijack (Your Hormones Might Get Jealous)

You’ve probably heard the glorious claim: spearmint tea is a natural hero for lowering testosterone, especially if you’re dealing with hormonal acne or PCOS. And it’s true! It works. But here’s the rub—it works a little too well for some of us. Drinking large amounts (think more than two cups a day) can actually tank your testosterone levels below the healthy zone.

For the ladies, that can mean a drop in libido (yeah, that spark might fizzle out) or even a wonky menstrual cycle. For the guys out there—yes, I’m talking to you, Chad who buys the organic spearmint—you might notice your morning motivation (both mental and… physical) taking a vacation. Oops. It’s a gentle herb, but it doesn’t mess around.

The “Am I Pregnant?” Scare

Another fun one: because spearmint messes with your hormones, it can occasionally mimic early pregnancy symptoms. You might find your breasts feeling a bit tender, or you get sudden mood swings over a misplaced avocado. And yes, a cup of tea can do that. It’s enough to make you buy a three-pack of pregnancy tests from the dollar store.

I’m not saying you’re going to have a phantom pregnancy after a tea party, but if you’re trying to conceive or on hormonal birth control, you might want to check with your doc. The herb can theoretically interfere with how your body processes estrogen and progesterone. Knowledge is power, folks, even if that power comes with a confusing side of “wait, am I crying because of the tea or because of my boss?”

The Stomach Grumbles (Goodbye, Peaceful Tummy)

Here’s the ironic part: spearmint is often marketed as a digestive aid. Drink it after a heavy meal, they say. It’ll soothe your stomach! But for some people—raises hand—it does the exact opposite. That gentle minty flavor can actually relax the lower esophageal sphincter too much, letting stomach acid creep back up. Hello, heartburn.

And if you’re sensitive to menthol, you might get cramps or a sudden, urgent trip to the bathroom that feels less like a “cleanse” and more like a betrayal. Your gut bacteria aren’t always fans of minty surprises. So if you start drinking this tea by the gallon for your skin, but your stomach starts staging a protest, you know what the culprit is.

The “Did I Just Fall Asleep Standing Up?” Effect

Let’s talk about the drowsiness. It’s subtle at first. You sip your tea, feel cozy, and think, “Wow, I’m so relaxed.” Then, two hours later, you’re struggling to keep your eyes open during a Zoom call where you’re supposed to actually talk. Spearmint has mild sedative properties, which is great for bedtime—but terrible if you’re trying to function in the real world.

I once had a cup at 2 PM, and by 3 PM I was yawning so hard I dislocated my jaw. Okay, I didn’t, but you get the picture. If you have a history of low blood pressure, this tea can make you feel even more floaty and spacey. Pro tip: save the sipping for the evening unless you want to become best friends with your couch.

4 Benefits Of Spearmint Tea For Acne And Its Side Effects

Are There Any Drug Interactions? (Spoiler: Yes)

You might think herbs are harmless, but spearmint can be a bit of a meddler. It can increase the activity of certain liver enzymes, which basically tells your body to process some medications faster. That includes things like statins, certain antidepressants, and even birth control pills. If you’re on regular meds, sudden heavy spearmint tea intake could make them less effective.

Also, if you have kidney issues? Pump the brakes. The spearmint contains a compound called pulegone, which in extremely high doses (think concentrated oil, not tea bags) can be toxic to the kidneys. Are you going to juice a field of the stuff? No. But it’s worth knowing that “more is better” is a dangerous mindset, even with a cute cup of herbal tea.

The Final Sip: Keep It Casual, Not Obsessive

Look, I still drink spearmint tea. I’m not quitting it over a few side effects. But now I keep it to one cup a day, max two, and I actually listen to my body. Your skin might thank you for the spearmint, but your hormones and your stomach might want a thank-you note too. So don’t go chugging it like you’re in a herbal tea drinking contest.

If you start feeling weird—sleepy, bloated, or suddenly jealous of everyone’s energy—cut back and see what happens. Your body is not a science experiment (or at least, it shouldn’t be a messy one). Drink your tea, enjoy the minty vibes, but remember: even the most innocent-looking leaf has a bit of a bite. Now, if you’ll excuse me, I’m going to pour myself a cup—just one—and maybe add a nice, grounding nap to my schedule.
