Before discussing what happens to your body when you drink spearmint tea, it's important to state that this information is for general knowledge and should not be taken as medical advice. Always consult with a healthcare provider before making any changes to your diet or health regimen.
Spearmint tea is a naturally caffeine-free herbal infusion made from the leaves of the Mentha spicata plant. Beyond its refreshing taste, this beverage is associated with a range of physiological changes in the body, driven by its rich content of beneficial compounds like rosmarinic acid, flavonoids, and carvone. While more human research is needed to confirm all effects, existing studies provide compelling insights into its potential impact.
The Anti-Androgenic Effect on Hormones
One of the most researched benefits of spearmint tea is its anti-androgenic effect, particularly in women. Androgens are male hormones, like testosterone, that are present in both men and women. High levels of androgens can lead to conditions such as polycystic ovary syndrome (PCOS), which is associated with irregular periods, hormonal acne, and hirsutism (excessive facial and body hair).
In studies involving women with PCOS, drinking spearmint tea has been shown to reduce free testosterone levels. For example, a study involving women with PCOS found that drinking spearmint tea resulted in lower testosterone levels and improved follicular hormone levels over a period of time. By helping to balance hormone levels, spearmint tea can be a supportive addition for managing these related symptoms.
Digestive System Relief
For those who experience digestive discomfort, spearmint tea may offer a gentle and effective remedy. The herb contains a compound called (-)-carvone, which has been shown to inhibit muscle contractions in the digestive tract. This antispasmodic property can help relieve symptoms like gas, bloating, and stomach cramps. The tea's relaxing effect on the stomach muscles is often used to calm indigestion and nausea. While more research is needed specifically on the tea, anecdotal evidence has long supported its use as a digestive aid.
High in Antioxidants and Anti-inflammatory Properties
Like many plant-based foods, spearmint is packed with antioxidants, including rosmarinic acid, flavones, and flavanones. These compounds help protect your cells from damage caused by free radicals, which are harmful molecules that contribute to oxidative stress. Oxidative stress is linked to several chronic conditions, including heart disease and cancer. Regular consumption of spearmint tea can help increase your body's antioxidant defenses. The rosmarinic acid also provides significant anti-inflammatory benefits, which can help with conditions like osteoarthritis, reducing joint stiffness and improving physical mobility.
Potential Effects on Brain Health
Emerging research suggests that spearmint may also have a positive impact on cognitive function, particularly memory. Studies on older adults with memory impairment have shown that supplementation with spearmint extract can lead to improved working memory. The exact mechanisms are still being explored, but these findings highlight a potential benefit for brain health as part of a balanced diet.
Aiding Relaxation and Sleep
Spearmint tea is known for its calming properties and is used in some cultures to promote relaxation and help with insomnia. While more human research is needed, animal studies have shown that spearmint extract can help reduce anxiety and improve sleep. The presence of menthol in the leaves is thought to contribute to this sedative effect, making a cup of spearmint tea a soothing addition to a bedtime routine.
Comparing Spearmint and Peppermint Tea
| Feature | Spearmint Tea | Peppermint Tea |
|---|---|---|
| Flavor | Mild, sweeter mint flavor | Strong, potent, and sharp menthol flavor |
| Menthol Content | Lower menthol content | Higher menthol content |
| Hormonal Effects | Anti-androgenic effects, beneficial for PCOS and hirsutism | No proven effect on hormonal acne |
| Digestive Impact | Calming, antispasmodic effect on digestive muscles | Stronger effects, sometimes used for IBS symptoms |
| Consideration for GERD | May trigger or worsen GERD symptoms due to relaxing the lower esophageal sphincter | Can also worsen GERD symptoms, but often more potently due to higher menthol content |
Important Considerations and Risks
While generally safe for most people, excessive consumption of spearmint tea may have side effects for certain individuals. The tea can relax the lower esophageal sphincter, potentially worsening symptoms for those with Gastroesophageal Reflux Disease (GERD). Some animal studies have also shown high doses of spearmint extract to have adverse effects on male fertility, though human research on tea consumption shows minimal risk. As with any herbal remedy, individuals with pre-existing conditions affecting the kidneys or liver, or those who are pregnant or breastfeeding, should consult a healthcare provider before use.

Conclusion: A Refreshing Path to Wellness
Drinking spearmint tea offers a multifaceted approach to wellness, influencing various systems throughout the body. Its rich antioxidant profile supports cellular health and combats inflammation, while its unique anti-androgenic properties provide specific relief for women with hormonal imbalances like PCOS. It can also serve as a gentle aid for digestive issues and contribute to improved memory and relaxation. While research is ongoing, the overall profile suggests that incorporating spearmint tea can be a simple, natural, and flavorful addition to support your health. As with any wellness practice, consistency and moderation are key to reaping the benefits and minimizing potential side effects.
