Two studies in women with facial hair have shown that drinking spearmint tea may help. High levels of male hormones, or androgens, are linked to an overgrowth of facial hair in women ( 9).

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). 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 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).Īt 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. 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). Spearmint is commonly used to help relieve symptoms of indigestion, nausea, vomiting and gas.
