Surprising Uses of Vicks VapoRub You Probably Didn’t Know About

Vicks VapoRub has been a familiar household product for generations, traditionally used to temporarily relieve cough associated with the common cold. But over the years, people have discovered plenty of other ways they like to use this distinctive mentholated ointment around the house and in their personal routines.

Some of these uses are surprisingly practical—although not every popular internet hack is backed by good evidence.

1. A Cooling, Aromatic Chest Rub

The classic use is still one of the most familiar. When used as directed on the chest and throat, the mentholated vapors can create a cooling sensation and may make a cough feel temporarily less bothersome.

It’s important to follow the product label rather than applying more than recommended.

2. Soothing Dry Skin on Hands and Feet

Some people use petroleum-based ointments on particularly dry areas such as heels, elbows, and hands. VapoRub contains petroleum jelly along with other ingredients, so some users find it helpful as part of a nighttime moisturizing routine.

For cracked heels, applying a small amount and wearing clean cotton socks overnight can help keep moisture against the skin. However, it isn’t a substitute for treatment if cracks are deep, bleeding, infected, or associated with an underlying skin condition.

3. A Household Odor Experiment

Because VapoRub contains strongly scented ingredients such as menthol and eucalyptus oil, its smell can be quite noticeable.

Some people place a small amount on a cotton ball and use it as a temporary way to introduce a strong scent into an area. Keep it away from children and pets, and don’t place it where the ointment could accidentally be touched or ingested.

4. The Internet’s Famous Toenail Hack

You’ve probably seen claims that rubbing VapoRub on discolored or thickened toenails can cure fungal infections.

This is one of those hacks where the evidence is limited. Some small studies have investigated ingredients found in VapoRub, but that doesn’t make it a proven treatment for toenail fungus. Persistent nail changes are worth discussing with a healthcare professional, especially because several different conditions can make a nail look abnormal.
