Spearmint Tea: 15 Health Benefits, Side Effects & How to Make It

In a world full of herbal wonders, spearmint tea has quietly claimed its spot as one of the most soothing and healing brews out there. Known for its refreshing aroma and cool, minty flavor, this tea does more than just lift your spirits — it can genuinely uplift your health too.

Whether you’re someone looking to calm an upset stomach, balance hormones, or simply sip on something relaxing, spearmint tea might just become your new best friend. Let’s dive into what spearmint tea is, its many health benefits, potential side effects, how to make it, and smart tips for getting the most out of every cup.

What is Spearmint Tea?

Spearmint tea is a herbal infusion made from the leaves of the spearmint plant (Mentha spicata) — a close cousin of peppermint. Unlike peppermint, which has a stronger, more pungent flavor due to high menthol content, spearmint has a sweeter, milder taste that makes it great for sipping, even without added sweeteners.

The spearmint plant is native to Europe and Asia but is now grown worldwide. Its leaves are rich in antioxidants, flavonoids, and essential oils like carvone and limonene, which give the tea its signature scent and healing properties.

15 Health Benefits of Spearmint Tea

Let’s take a closer look at why so many herbalists and wellness enthusiasts swear by spearmint tea:

1. Balances Hormones in Women

Spearmint tea has anti-androgen properties, which means it may help reduce excess male hormones in women, particularly useful for those with PCOS (Polycystic Ovary Syndrome). Several studies suggest it can reduce testosterone levels and improve symptoms like acne and irregular periods.

2. Improves Digestion

Feeling bloated or gassy? Spearmint tea acts as a natural digestive aid, easing nausea, indigestion, and flatulence. Its soothing effect on stomach muscles can reduce spasms and cramps.

3. Soothes Stress and Anxiety

The subtle aroma and cooling sensation of spearmint tea have calming effects on the nervous system, helping to reduce tension and promote better sleep.

4. Supports Cognitive Function

Spearmint contains compounds like rosmarinic acid that may enhance memory and brain function, especially in older adults. Some early studies even suggest it could support brain health over time.

5. Fights Acne and Skin Inflammation

Thanks to its hormone-regulating and anti-inflammatory properties, spearmint tea may help reduce acne flare-ups and improve overall skin clarity.

6. Reduces Hirsutism

Hirsutism (excess facial or body hair in women) is often linked to high testosterone. Regular consumption of spearmint tea has been shown to help lower androgen levels, reducing unwanted hair growth over time.

7. Freshens Breath Naturally

Spearmint is famous for its refreshing scent — and drinking it as a tea can help eliminate bad breath by killing odor-causing bacteria.

8. Anti-inflammatory Benefits

The flavonoids and phenolic compounds in spearmint tea help reduce inflammation, making it a useful addition to a diet focused on reducing chronic pain or autoimmune symptoms.

9. Relieves Menstrual Cramps

Women have used spearmint tea for centuries to ease the pain and discomfort of menstruation. Its natural muscle-relaxing properties can reduce uterine spasms and lower pain intensity.

10. Supports Weight Loss

While not a magic bullet, drinking spearmint tea may help with weight management by curbing appetite and improving digestion.

11. Improves Sleep Quality

Sipping a cup before bedtime may help you fall asleep faster and enjoy deeper, more restful sleep — all without the grogginess that comes with sleeping pills.

12. Regulates Blood Sugar Levels

Some preliminary studies suggest spearmint tea may have a hypoglycemic effect, helping to balance blood sugar levels and reduce insulin spikes.

13. Boosts Immunity

Its antimicrobial and antioxidant properties help strengthen the immune system, making your body more resilient to common colds and infections.

14. Reduces Nausea and Vomiting

Whether you’re dealing with morning sickness or post-meal queasiness, spearmint tea can settle your stomach and reduce the urge to vomit.

15. Acts as a Natural Decongestant

Suffering from a cold or allergy? Spearmint tea can help clear nasal congestion, soothe sore throats, and calm coughing.

Side Effects of Spearmint Tea

While spearmint tea is generally safe, too much of anything can be a problem. Here are some possible side effects:

1. Hormonal Disruption in Men

Because it reduces testosterone, men who drink large amounts regularly may experience lower libido or hormonal imbalance.

2. Kidney or Liver Concerns (In Large Doses)

Excessive consumption may burden your kidneys or liver, especially if taken with other herbs or medications that impact these organs.

3. Allergic Reactions

Though rare, some people may be allergic to mint and could experience rashes, itching, or breathing problems.

4. Heartburn

In certain people, spearmint can relax the lower esophageal sphincter, potentially making acid reflux worse.

5. Low Blood Sugar

Those already taking medication for diabetes should be cautious — spearmint tea can sometimes lower blood sugar too much.

6. Interference with Iron Absorption

Spearmint tea may inhibit non-heme iron absorption (plant-based iron), so avoid drinking it with meals if you’re iron deficient.

7. Drug Interactions

Spearmint can interfere with hormone therapies, sedatives, and some antibiotics. Always consult your doctor if you’re on medication.

8. Dehydration

Although it’s herbal, it’s still a mild diuretic. Drinking excessive amounts could lead to increased urination and dehydration.

9. Pregnancy Caution

While small amounts are likely safe, large quantities may affect pregnancy hormones, so always consult your OB-GYN first.

10. Over-relaxation of Muscles

In rare cases, its relaxing effects on muscles may lead to dizziness or fatigue, especially if consumed in high doses.

How to Make Spearmint Tea?

You don’t need a fancy setup to enjoy spearmint tea — just some leaves and hot water. Here’s how to brew the perfect cup:

Ingredients:

  • 1 tablespoon fresh spearmint leaves (or 1 tsp dried)
  • 1 cup hot water (about 200°F or 93°C)

Instructions:

  1. Rinse the spearmint leaves to remove any dirt or residue.
  2. Place the leaves in a teapot or cup.
  3. Pour hot water over the leaves and cover.
  4. Let steep for 5–7 minutes (longer for a stronger flavor).
  5. Strain and serve hot or cold. Add honey or lemon if desired.

Pro Tip: You can double the amount and refrigerate the extra for iced spearmint tea — perfect for warm days!

Tips for Consuming Spearmint Tea Safely & Effectively

Here are a few expert-backed suggestions for making the most out of your spearmint tea experience:

1. Start Slowly

Begin with 1 cup per day to see how your body reacts. Gradually increase to 2–3 cups if needed.

2. Timing Matters

Drink in the evening to unwind, or between meals to improve digestion without interfering with nutrient absorption.

3. Cycle Your Intake

If you’re drinking it for hormone balancing or skin health, consider using it for 3–4 weeks on, 1 week off to avoid overuse.

4. Switch with Other Teas

Mix up your herbal routine by alternating with chamomile, ginger, or rooibos tea to give your body variety.

5. Try It Cold

Spearmint tea is incredibly refreshing as an iced tea. Add cucumber slices or citrus for a detoxifying summer drink.

6. Use Organic Leaves

If possible, choose organic, pesticide-free spearmint (especially if you’re harvesting your own). This avoids ingesting harmful chemicals.

7. Store Properly

Keep dried spearmint in an airtight container away from direct sunlight to preserve its oils and flavor.
