We have no idea why someone first experimented with Vicks VapoRub on the soles of the feet. We do know that whenever we publish a story about putting Vicks on the feet for a nighttime cough we hear from skeptics who insist that this is a placebo effect. Since there are no scientific studies to prove otherwise, we shrug and say that it works for us and a lot of readers of our syndicated newspaper column. Now we can add that a doctor recommended Vicks on the feet for a nighttime cough and told his patient that it works for him.
A Reader Shares Her “Magic”:
Q. I was struggling with a cough for six weeks, especially at night when I was lying down. After two fruitless visits to urgent care, I finally went to my primary care doctor.
He diagnosed walking pneumonia and prescribed a powerful antibiotic and some meds to heal my throat, because it was irritated from the coughing. When I told him about how bad it was at night, he recommended Vicks VapoRub on the bottom of my feet when I went to bed. I thought he was joking, but he told me it worked for him and urged me to give it a try.
I did so that very night and I’m telling you it was like magic! I had gotten up five straight nights to sit up because my coughing was so bad. I slept through the night with Vicks with little to no coughing every night thereafter.
A. Thanks for sharing your success story! Eucalyptol, thymol and menthol are ingredients in Vicks, and they can help ease a cough. The question is why apply it to your feet? These compounds activate transient receptor potential (TRP) channels found in nerves that are plentiful in the soles.

The “Niece Study” Of Vicks on the Feet:
Q. I had a pretty mild cold about a week ago that turned into a nasty cough. The sore throat, sneezing and congestion disappeared within three days but this darn cough won’t let go. It keeps waking me up at night. Cough medicine doesn’t help. Do you have any remedies that might let me get a decent night’s sleep?
A. A remedy that has a lot of support from readers is Vicks VapoRub smeared on the soles of the feet.
Here is just one of many stories we have received:
“I have used Vicks numerous times for my husband and me. It worked but I didn’t know if it was due to a placebo effect (and I didn’t really care, so long as it worked).
“Our nieces were staying with us a few years ago and they both had a nagging cough. One night the older niece was coughing in her sleep. I went in her room, put Vicks on the soles of her feet and put socks on her. She didn’t cough the rest of the night.
“The next night, the younger niece was coughing. I did the same to her and she didn’t cough any more that night either. Neither of the girls knew that I had put the Vicks on their feet so the placebo effect seems unlikely.”
Vicks Calmed a COVID Cough:
Q. I had a very mild (but long lasting) case of COVID-19 last year. I am fully vaxxed and boosted. Although it was less troublesome than a cold, it did induce a dry cough that made it hard to sleep.
Vicks VapoRub to the rescue! Actually, I used a house brand and slathered it on the soles of both feet. Then I put on my thick socks and was relieved to find the coughing minimized. I hope others get the same benefit.
A. We’re glad you have recovered fully from COVID-19. Many people report a lingering cough that may last several months.
Thank you for sharing your success story with Vicks VapoRub. We have heard from many readers that this approach can be helpful against coughs related to colds or influenza. You are the first to report using it against a COVID-related cough. There is more information about Vicks and other cough remedies in our eGuide to Colds, Coughs & the Flu.
A Semi-Scientific Hypothesis for Vicks on the Feet:
The soles of your feet are loaded with nerves. We hypothesize that the camphor and menthol (and possibly other ingredients in Vicks) stimulate TRP (transient receptor potential) channels in the sensory neurons in the feet.
When these nerves are activated they send messages to the spinal cord. We suspect that those messages calm the cough center, just above the spinal cord. This might well explain how a cough quiets so quickly with Vicks on the feet.

More Reports from Readers About Vicks on the Feet:
Robin in North Carolina got an added bonus:
“I do this regularly. I apply Vicks on my feet whenever I have a cough. It does work.
“There is another benefit that I receive by doing this. My feet became really soft. I have always had a problem with dryness on the soles of my feet. They would crack and peel, always in the winter months or the middle of the summer.
“I would end up with a horrendous cough from allergies and sinus infections. The Vicks on my feet with socks not only would help with my cough, but it helped the skin on the soles of my feet as well.”
Nam in Westminster, California, was a skeptic…until:
“I was trained in medicine and always have a scientist’s mind. I never believed in this.
“About 10 years ago I had a real bad cold and coughed uncontrollably day and night. My wife kept telling me to apply Vicks on the feet at night so we both could sleep. I kept telling her it would not work. Don’t even try it.
“She waited until I felt asleep. She applied Vicks to both of my feet and pulled my socks back on (I knew but because I was so tired, I just let her finish) and I slept like a baby that night.
“In the morning, I thanked her and said I was wrong all along, I thought it never would have worked. I applied another layer of Vicks to both of my feet and went to work. All that day I did not cough at all. I did the same thing the next few nights and days and my cough just never came back.
“I told my colleagues and they were surprised. Some tried this technique themselves and agreed with me. Because of the guidelines and regulations, physicians can’t tell patients about this remedy but their office employees can.”
