A Listerine foot soak is, as the name suggests, an at-home treatment that involves soaking feet in a bath of Listerine mouthwash and water. Proponents of this therapy say that it may help treat athlete’s foot (a fungal foot infection), soothe dry, cracked, and scaly feet, and even treat diabetic foot pain.

It’s true that ingredients in Listerine contain antibacterial, antioxidant, and antifungal properties. However, there are no official studies to back any claims about the benefits of a Listerine foot soak.

That said, this remedy is inexpensive, easy to make, and safe for most people, if you want to give it a try.

This article explains the possible benefits of a Listerine foot soak. It covers some side effects you should be aware of and includes a few notes on who should (and should not) try a Listerine foot soak.

Listerine Foot Soak Benefits

There is no research regarding Listerine foot soaks specifically. But research does confirm that four essential oils found in Listerine have antimicrobial and antifungal properties that may help kill fungi and bacteria:

Thymol, the main active compound in thyme, has antiseptic, antibacterial, antifungal, anti-parasitic, and antioxidant qualities. Its anti-inflammatory properties may soothe skin irritation, itching, and redness.

Menthol, an oil from the menthol plant, has antibacterial, antifungal, anti-itch, and pain-relieving qualities. Menthol has a cooling effect that makes it a common ingredient in icy-hot patches and other similar products.

Eucalyptol, the main active compound in eucalyptus, has anti-inflammatory and antioxidant qualities and can help speed up recovery time. Research shows that eucalyptol has tremendous potential for treating diabetes-related pain and infectious diseases.

Methyl salicylate, a compound derived from wintergreen or sweet birch bark, is a common ingredient in topicals used to treat musculoskeletal aches and pains. Methyl salicylate also helps the skin absorb other herbal ingredients better.

Simply soaking your feet in warm water has benefits in and of itself: As anyone who has ever gotten a pedicure knows, enjoying a warm footbath can be relaxing and soothing to the skin.

The practice also has study-proven benefits: Several studies have found that soaking feet and lower legs in warm water for 20 to 60 minutes before bed significantly improves sleep quality. Other studies suggest a footbath can help improve circulation to the lower extremities.

A Word From Verywell 

Soaking your feet in Listerine may sound a little funky. But if this practice intrigues you, there’s no real harm in trying it, as long as you don’t have any other skin conditions. A Listerine foot soak may even have some benefits, like cooling you off, easing aches and pains, or helping you sleep.

That said, using an over-the-counter antifungal cream or other medical treatment is still the fastest, more effective way to clear up athlete’s foot and toenail fungus.
