Overview InformationSpearmint is an herb. The leaves and oil are used to make medicine.
Spearmint is used to improve memory, digestion, stomach problems, and other conditions, but there is no good scientific evidence to support these uses.
How does it work?The oil in spearmint contains chemicals that reduce inflammation (swelling) and change levels of chemicals called hormones, such as testosterone, in the body. Some chemicals might also harm cancer cells and kill bacteria.
Uses & Effectiveness
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.
- Memory and thinking skills (cognitive function). Taking spearmint extract might improve attention in some people. But any benefit seems to be small. Spearmint extract doesn't seem to improve most other measures of memory and thinking skills. Chewing spearmint-flavored gum doesn't appear to improve any measures of memory of thinking skills in healthy adults.
- 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.
- 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 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.
- Gas (flatulence).
- Muscle pain.
- Skin conditions.
- Sore throat.
- Other conditions.
Side Effects & SafetyWhen taken by mouth: Spearmint and spearmint oil are LIKELY SAFE when eaten in amount commonly found in food. Spearmint is POSSIBLY SAFE when taken by mouth as a medicine, short-term. Side effects are very uncommon. Some people might have an allergic reaction to spearmint.
When applied to the skin: Spearmint is POSSIBLY SAFE when applied to the skin. It might cause an allergic reaction in some people. But this is rare.
Special Precautions & Warnings:Pregnancy: Spearmint is POSSIBLY UNSAFE when taken by mouth in large amounts during pregnancy. Very large doses of spearmint tea might damage the uterus. Avoid using large amounts of spearmint during pregnancy.
Breast-feeding: There isn't enough reliable information to know if spearmint is safe to use when breast-feeding. Stay on the safe side and avoid using in amounts greater than those found in food.
Kidney disorders: Spearmint tea might increase kidney damage. Higher amounts of spearmint tea seem to have greater effects. In theory, using large amounts of spearmint tea might make kidney disorders worse.
Liver disease: Spearmint tea might increase liver damage. Higher amounts of spearmint tea seem to have greater effects. In theory, using large amounts of spearmint tea might make worsen liver disease.
We currently have no information for SPEARMINT Interactions.
The appropriate dose of spearmint depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for spearmint. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
