If you mean Vicks VapoRub, putting it on your feet before bed is a popular home remedy, but many of the claimed benefits aren’t supported by good scientific evidence.
What it may actually do
Moisturize dry feet — the petrolatum base can soften dry skin.
Create a cooling/warming sensation — menthol and camphor can produce a noticeable sensation on the skin.
Make feet smell less noticeable — the strong mentholated fragrance can temporarily mask odors.
Feel soothing before bed — the scent and sensation may feel relaxing to some people, although this is subjective.
What it probably doesn’t do
There is no good evidence that applying VapoRub to the soles of the feet treats coughs, colds, infections, or other internal illnesses. The manufacturer’s directions for cough relief call for application to the chest and throat, not the feet.
Don’t apply it to broken or irritated skin, and don’t ingest it. Camphor can be toxic if swallowed, particularly by children.
If you’re considering it specifically for cough, fungal feet, neuropathy, or poor circulation, tell me which one—because the safest and most effective approach is different for each.
