Uses
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate. The effectiveness ratings for SPEARMINT are as follows:
Insufficient evidence to rate effectiveness for…
- The decline in memory and thinking skills normally occurs with age. Early research shows that taking an extract daily might help with thinking skills in older adults who have started to notice problems with thinking.
- Memory and thinking skills (cognitive function). Taking spearmint extract might improve attention in some people. But any benefit seems to be small. Extract doesn’t seem to improve most other measures of memory and thinking skills. Chewing flavored gum doesn’t appear to improve any measures of memory or thinking skills in healthy adults.
- Male-pattern hair growth in women (hirsutism). Early research shows that drinking 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.
- A long-term disorder of the small intestines that causes stomach pain (irritable bowel syndrome or 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 tea reduces pain and stiffness by a small amount in people with knee osteoarthritis.
- Nausea and vomiting after surgery. The use of aromatherapy with oils of ginger, spearmint, peppermint, and cardamom seems to reduce symptoms of nausea in people after surgery.
- Cancer.
- Colds.
- Cramps.
- Diarrhea.
- Gas (flatulence).
- Headaches.
- Indigestion.
- Muscle pain.
- Skin conditions.
- Sore throat.
- Toothaches.
- Other conditions.
More evidence is needed to rate the effectiveness of spearmint for these uses.
