CBD creams and lotions are infused with cannabidiol. Manufacturers claim that CBD products can be used as a pain reliever. They are commonly used for soreness, irritated skin, and inflammation. There is a difference between taking CBD and applying it on the skin. By applying it on the skin, there are no side effects compared to taking it orally. CBD is similar with THC just without the psychoactive effect. CBD creams and lotions can be an alternative for those who are not comfortable in taking THC.
Pharmacology published a study in 2016 looking at medical marijuana for migraines, specifically in relation to its effects on serotonin, with very positive results. You’ll notice that neither study looked at CBD in isolation from other cannabinoids (which is an issue with a lot of research on CBD and pain). Truthfully, the research on CBD alone just isn’t sufficient to make any pronouncements about its effects on headache pain.
