If you mean the popular claim about putting Vicks VapoRub on your feet before bed, there are a few things worth separating from the internet folklore.
4 commonly claimed benefits
1. It may soothe dry, rough feet
VapoRub contains ingredients in a petrolatum-based ointment. Applying an occlusive ointment to dry skin can reduce moisture loss and soften rough skin. However, you don’t need VapoRub specifically for this—plain petroleum jelly is usually a simpler option.
2. It can make feet feel more comfortable
The menthol and camphor in VapoRub produce a cooling/warming sensation that some people find soothing, particularly when applied to tired feet.
3. It may help with cracked heels
The ointment can help moisturize and soften thickened skin. For significantly cracked heels, dermatologists generally favor moisturizers containing ingredients such as urea, alpha-hydroxy acids or salicylic acid, followed by an occlusive moisturizer.
4. It may help with certain fungal foot problems—but evidence is limited
There are small studies suggesting some ingredients in VapoRub may have antifungal activity, and one small clinical trial found improvement in toenail fungus with prolonged use. But this is not strong enough evidence to consider VapoRub a first-line treatment for athlete’s foot or toenail fungus.
What about coughs and colds?
A very common claim is that rubbing Vicks on your feet will stop a cough overnight. There isn’t good scientific evidence that applying it to the feet treats a cough. VapoRub is labeled for use on the chest and throat for temporary relief of cough associated with the common cold, not the soles of the feet.
If you want to try it
Use it only on intact external skin, follow the product’s directions, and don’t put it on open wounds or irritated skin. Do not ingest it, and don’t use it in or around the nose or mouth. Camphor-containing products can be dangerous if swallowed, especially by children.
Bottom line: Vicks on the feet can act as a moisturizing/occlusive ointment and may feel soothing, but the popular claims that it cures coughs, colds, or infections simply by being applied to the feet are not well supported by evidence.
