Putting Vicks VapoRub on your feet before bed is a popular home remedy, but many claims about it are not strongly supported by scientific evidence. Here are four commonly mentioned benefits and what is known:
- May help moisturize dry feet
The ointment contains ingredients such as petrolatum that can act as a barrier to reduce moisture loss, which may soften rough, dry skin and cracked heels. - Can create a soothing bedtime routine
The cooling sensation and strong mentholated scent may feel relaxing for some people and become part of a calming nighttime routine. - May reduce the feeling of dry, irritated skin
The thick ointment layer can protect skin from friction and environmental dryness, which may make feet feel more comfortable. - May help with toenail appearance in some cases
Some small studies and anecdotal reports suggest that certain ingredients in VapoRub may help improve the appearance of nails affected by fungal infection, but results vary and it is not considered a first-line treatment.
A few cautions:
- Applying it to the feet does not have good evidence for stopping coughs or colds, even though this claim is widely shared online.
- Avoid using it on broken or irritated skin.
- Wash hands after applying, and avoid getting it near eyes or sensitive areas.
- For children under 2 years old, avoid use unless advised by a healthcare professional.
If you’re trying it for cracked heels or dry feet, applying a small amount and wearing cotton socks overnight is a common approach.
