1. Soothes Irritated Skin
Menthol creates a cooling sensation by triggering skin receptors that detect the sensation of coolness. (Capsaicin is on the other end of this spectrum. Found in hot chili peppers, it triggers a sensation of extreme heat.)
Menthol doesn’t actually cause a change in temperature; it just makes your skin feel cold. This makes it a popular ingredient in pain-relieving ointments. Usually, ointments contain menthol oil and not menthol crystals, as the raw crystals can cause skin irritation.
2. Relieves Sore Throat & Cold Symptoms
Menthol can be used as an expectorant and is often used to treat the flu, colds and bronchitis. It’s often the main ingredient in cough drops and chest rubs because it may help loosen mucus that causes congestion.
Menthol may also ease a sore throat by creating a cooling sensation that relieves pain. Using menthol crystals in a hot shower can release the vapors and soothe an irritated nose or throat.
And because menthol is an antibacterial, it’s often an ingredient in oral hygiene like mouthwash and toothpaste. It leaves a fresh, minty taste and fights bad breath.
3. Menthol and Pain Relief
Menthol is a common ingredient in lip balms, lotions and ointments, as well as arthritis and pain products. It creates cooling sensation that soothes muscle spasms and cramps.
So, how does menthol work its pain-relieving magic? Though scientists aren’t exactly sure, they do have some theories. One reason may be menthol’s interaction with the skin’s TRPM8 receptors, which sense feelings of coolness. When the skin feels cooler, it creates a slight feeling of numbness. This, in turn, helps lessen pain.
4. Relieves IBS Symptoms
People have used mint to calm digestive upset for thousands of years, and evidence suggests it could relieve symptoms of irritable bowel syndrome (IBS). In patients with IBS, the muscles of the colon tense up and spasm, causing cramps, inflammation and pain. But menthol could ease inflammation, pain and cramping associated with IBS, especially menthol sourced from peppermint.
In one study, patients with IBS reported a significant improvement in their IBS symptoms—including stomach pain—after taking menthol sourced from peppermint.
