Spearmint is a minty herb that’s high in antioxidants and other beneficial plant compounds. It may help balance hormones, lower blood sugar and improve digestion, and can also reduce stress and improve memory.
Spearmint, or Mentha spicata, is a type of mint similar to peppermint.
It’s a perennial plant that hails from Europe and Asia but now commonly grows on five continents around the world. It gets its name from its characteristic spear-shaped leaves.
Spearmint has a pleasantly sweet taste and is frequently used to flavor toothpaste, mouthwash, chewing gum and candy.
One common way to enjoy this herb is brewed into a tea, which can be made from either fresh or dried leaves.
Yet, this mint is not only tasty but may also be good for you.
Spearmint is commonly used to help relieve symptoms of indigestion, nausea, vomiting and gas.
The compound (-)-carvone, which is naturally found in spearmint, has been shown to strongly inhibit muscle contractions in the digestive tract, which may explain how this herb helps relieve digestive upsets (1).
In an eight-week randomized study in 32 people with irritable bowel syndrome (IBS), one group was given a product containing spearmint, lemon balm and coriander along with loperamide for diarrhea or psyllium for constipation (2).
At the end of the study, people who received the spearmint-containing supplement reported less abdominal pain, discomfort and bloating compared to those in the placebo group.
This herb may also relieve nausea and vomiting caused by chemotherapy.
In one study, spearmint essential oil applied to the skin significantly reduced the incidence of nausea and vomiting compared to a placebo (3).
Antioxidants are natural chemical compounds found in plants that help protect against and repair damage caused by free radicals, which are harmful molecules that can lead to oxidative stress.
Oxidative stress has been linked to several chronic conditions, including heart disease, cancer and diabetes (4).
Spearmint contains a large number of antioxidant compounds, including rosmarinic acid, flavones and flavanones like limonene and menthol (5).
Two tablespoons (11 grams) of spearmint also provides 2% of the Reference Daily Intake (RDI) for vitamin C, another potent antioxidant (6, 7).
According to researchers, spearmint shows excellent antioxidant activity against free radicals. In one study, extract from this herb prevented fat oxidation in meat and was as effective as the synthetic antioxidant BHT (8).
Summary Spearmint
For women with hormone imbalances, spearmint tea may provide relief.
Studies in women have shown that it can decrease male hormones like testosterone while increasing female hormones necessary for ovulation, such as luteinizing hormone (LH), follicle-stimulating hormone (FSH) and estradiol.
In one five-day study in 21 women with hormone imbalances, two cups of spearmint tea a day decreased testosterone and increased LH, FSH and estradiol levels (9).
Similarly, in a 30-day randomized study, 42 women with polycystic ovary syndrome (PCOS) who drank spearmint tea twice a day had lower testosterone levels and higher LH and FSH levels compared to women who drank a placebo tea (10).
Additionally, in a study in rats, spearmint essential oil was found to decrease testosterone and ovarian cysts and increase the number of viable eggs in the rats’ ovaries (11).
Summary Spearmint
Drinking spearmint tea may help reduce hirsutism, or growth of dark, coarse hair on the face, chest and abdomen of women.
In fact, it’s a common herbal remedy for unwanted hair growth in Middle Eastern countries (12).
High levels of male hormones, or androgens, are linked to an overgrowth of facial hair in women (9).
Two studies in women with facial hair have shown that drinking spearmint tea may help.
In one five-day study, 12 women with PCOS and nine women with facial hair due to unknown causes were given two cups of spearmint tea twice a day during the follicular phase of their menstrual cycle (9).
While the study was not long enough to determine whether spearmint affected facial hair, the women’s testosterone levels were reduced.
There’s some evidence that this herb may help improve memory.
Studies have shown that mice given a spearmint extract experienced improved learning and memory as shown by their performance on a maze test (13).
Previous studies in humans found that chewing mint-flavored gum may help improve memory. However, later studies have failed to confirm its beneficial effects. (14, 15, 16).
In a more recent study, older adults with memory impairment who were given daily supplements containing 900 mg of spearmint extract experienced a 15% improvement in working memory (17).
Therefore, the evidence on the benefits of this type of mint for memory is limited but promising — especially for older adults.

While human-based studies on this potential effect are lacking, animal studies have shown promising results.
In one study, rats were given a spearmint extract equivalent to 9 mg per pound (20 mg per kg) of body weight per day. While healthy rats appeared unaffected, rats with diabetes had significantly lower blood sugar (21).
