If you have ever had leg cramps, you know that these muscle spasms can be extremely painful. There is no standard medical treatment for this problem, partly because the cause is not well understood (European Journal of Neurology, Feb. 2019). Water alone may increase the likelihood of cramps or spasms. Some scientists prefer restoring electrolytes along with fluids after exercise. However, this takes up to an hour (BMJ Open Sport & Exercise Medicine, March 5, 2019). A reader reports that liquid soap is much quicker.
Liquid Soap to Relieve Leg Cramps:
Q. I have suffered from restless legs syndrome for years. I got a little relief from keeping bars of soap in the bed.
Then, on a road trip where I had to do all the driving, I experienced hours of leg spasms. It was so bad I was crying from the pain.
In desperation I bought some liquid soap from a roadside service station and tried rubbing it on my calves. I had complete relief within two miles.
I have told at least 25 people, and every one of them experienced almost instant relief. An antique dealer saw me in town and came over and hugged my neck right there in front of everybody! He said he was finally sleeping well after 20 years of suffering.
Is Liquid Soap Too Silly to Try?
A. Many people laugh at the idea of using soap for leg cramps or restless legs syndrome. It seems like such a silly remedy. Nevertheless, there is some science to support it.
Over a decade ago an anesthesiologist published the results of a study that tested crushed Ivory soap in skin patches (Journal of Alternative and Complementary Medicine, July, 2008). The researchers reported positive results for women with menstrual cramps.
In another study this physician tested soap-scented oil (SSO) in a special skin patch he had created.
He reported that:
“the SSO skin patch consistently and adequately relieved muscular pain” (Journal of Multidisciplinary Healthcare, Sept. 2008).
The soap scented oil doesn’t seem that different from the liquid soap you used. Unfortunately, he published this research shortly before he retired, and his colleagues have not followed up with further studies. We suspect that the soap scent operates through transient receptor potential (TRP) channels.
