According to the theory, this stimulation is passed up the spinal cord to the medulla oblongata in the brain. The medulla oblongata is the part of your brain that regulates coughing. Some compare this idea to a theory about muscle cramps.
Some scientists think hyperactivity of certain nerves may cause at least one type of muscle cramp. A number of studies have shown that a drink made with strong spices can be helpful for these types of cramps.
Spices like cinnamon and capsaicin , the compound that makes peppers hot, may distract the nerves that cause these cramps. According to the theory, VapoRub might have a similar effect on the nervous system. This effect, if it exists, would be separate from VapoRub's aromatherapy effect. So it might help a cough even though it is applied far away from the nose. It's important to remember, though, that a plausible idea isn't the same thing as a tested scientific theory. Scientific theories are put through rigorous study before they are confirmed.
Many plausible-sounding theories have been proven false by research. There have been no scientific studies into VapoRub's effectiveness when used on the feet. Without these studies, it is impossible to say whether or not it works this way. Vicks VapoRub is an over-the-counter product that has been in use for a long time. This may make it seem like it has minimal risks. But there are some serious warnings about this product you should pay attention to. Putting Vicks VapoRub under the nose can lead to respiratory distress or difficulty breathing.
This has been proven through studies and real-world incidents. There is no evidence that using Vicks VapoRub on your feet will help ease a cough. This product may seem to help because menthol vapors make you feel as if you are breathing more easily. VapoRub is not safe for children under 2. It contains camphor, which is poisonous if swallowed. This product should only be used on the chest, and only by adults and children over the age of 2. Vicks VapoRub is a popular product with some valid uses.
Still, some people use the product in ways that are unproven and come with serious risks. If you are concerned about cough and congestion, talk to your doctor about the best ways to ease symptoms. Never skip other treatments in favor of this product alone. One of the main ingredients in Vicks, menthol, has been shown to stimulate hair growth in animal studies, but the mix of ingredients in Vicks may not have the same benefits.
Ingesting a small taste will probably not be harmful to children or adults, but the camphor in Vicks is toxic and can cause vomiting, seizures, respiratory distress, coma, or even death, depending on how much is consumed. Vicks rubbed on the chests of children with cold symptoms can improve their quality of sleep. Looking to avoid getting the flu? Our free guide has everything you need to stay healthy this season.
Camphor is toxic to animals. It can cause a skin reaction, and in large enough amounts, it can cause seizures and even death. Dermatologists recommend petroleum jelly as a moisturizer, especially when used on damp skin, because it keeps moisture from evaporating.
That may explain why some people have found Vicks VapoRub helpful for healing rough skin on the feet and heels. But more research is needed to support the anecdotal claims about its usefulness as a treatment for dry, calloused skin on the feet. According to older research , the camphor oil found in Vicks VapoRub repels certain species of mosquitoes. Products containing menthol are also effective against mosquitoes, reports more recent research. However, while natural oils may provide some defense, if you really want to keep mosquitoes away, DEET and picaridin are still the most powerful repellents.
Beauty bloggers have promoted the use of Vicks VapoRub as an overnight spot treatment to shrink pimples. Several of the ingredients in Vicks VapoRub have been found to be effective at healing blemishes, but other ingredients may actually worsen acne.
For example, dermatologists have recommended camphor essential oil as an acne treatment. But another ingredient in Vicks VapoRub — petroleum jelly — may cause breakouts. The American Academy of Dermatologists recommends against using products with petroleum jelly on acne-prone skin.
If you want to take advantage of the anti-inflammatory properties of camphor, some beauty bloggers recommend mixing a few drops of camphor essential oil with a carrier oil like jojoba and dabbing it on a blemish.
Some small studies have shown that gels and ointments containing menthol have been effective at relieving headaches when applied to the base of the skull. However, the amount of menthol in the tested products was much higher 6 percent and 10 percent than the amount of menthol in Vicks VapoRub 2. Vicks VapoRub has been a medicine cabinet staple for more than years.
And at least one study found that it works to stamp out fungal infections in toenails. Vicks VapoRub is also a popular choice for people trying to fade stretch marks, heal rough skin, treat headaches, and keep outdoor bugs away. Some people have used the strongly scented ointment to keep pets from peeing on or scratching furniture, but be careful using this training method.
