To cool off a cold, try peppermint

Peppermint is approved in Europe for treating colds, coughs, dyspepsia and liver conditions. In this country, the hardy perennial is often found in herbal remedies for stomach ailments and is sold as a dietary supplement. The herb’s main ingredient is menthol, but it also contains flavonoids such as limonene.

Uses: Some herbalists recommend the herb or its oil for colds, coughs and headaches. It’s also sometimes used to ease upset stomachs, irritable bowel syndrome and indigestion.

Dose: For headaches, place a few drops of the oil in water and inhale the scent; for colds and gastrointestinal problems, take several hundred milligrams a day in capsule form.

Precautions: Peppermint can cause heartburn or headaches in people sensitive to it. It also can cause spasms or respiratory distress when applied to young children’s faces.

Research: Peppermint demonstrates antiviral and antibacterial properties in the lab. In animal studies, the herb relaxes the gastrointestinal tract and esophagus, suppresses the cough reflex and increases swallowing. Some human studies suggest that inhaling the oil’s aroma or applying it to the temples and forehead is an effective way to treat headaches.

Dietary supplement makers are not required by the U.S. government to demonstrate that their products are safe or effective. Ask your health-care provider for advice on selecting a brand.
