Traditionally Used for:
Memory. Chewing spearmint-flavored gum does not appear to improve memory in healthy adults.
Insufficient Evidence for
Decline in memory and thinking skills that normally occurs with age. Early research shows that taking an extract of a special type of spearmint daily might help with thinking skills in older adults who have started to notice problems with thinking.
Male-pattern hair growth in women (hirsutism). Early research shows that drinking spearmint tea twice daily for up to one month can decrease levels of male sex hormone (testosterone) and increase levels of female sex hormone (estradiol) and other hormones in women with male-pattern hair growth. But it doesn't seem to greatly reduce the amount or location of male-pattern hair growth in women with this condition.
Irritable bowel syndrome (IBS). Early research shows that using 30 drops of a product containing lemon balm, spearmint, and coriander after meals for 8 weeks reduces stomach pain in people with IBS when taken along with the drug loperamide or psyllium.
Osteoarthritis. Early research shows that drinking spearmint tea reduces pain and stiffness by a small amount in people with knee osteoarthritis.
Nausea and vomiting after surgery. Use of aromatherapy with oils of ginger, spearmint, peppermint, and cardamom seems to reduce symptoms of nausea in people after surgery.

There is not enough reliable information about the safety of taking spearmint if you are breast-feeding. Stay on the safe side and avoid using in amounts greater than those found in food.
