Cannabidiol, or CBD, is a nonpsychotropic compound derived from the plant family that contains Cannabis sativa. Most often, it is is extracted as an oil from industrial grade hemp. Although it was deemed at its discovery in 1940 not to have any medicinal properties, modern research has uncovered many medicinal uses. Regarding the question, "Can CBD Oil Be Applied Topically?" the answer is yes. In fact, most people who use the oil prefer topical application to oral administration or inhalation.
The chief use of topical CBD is pain reduction with inflammation reduction a secondary effect. Also, it works. The long version of "it works" comes from a government study in 2009 where the researchers concluded the following:
"Cannabidiol showed a positive allosteric modulating effect in a low micromolar concentration range." Ahrens, J., et al., U.S. National Library of Medicine National Institutes of Health.
Basically, CBD blocks the pain receptors of the human spinal cord by interfering with the enzymes that transmit the signals of pain between nerves. Coincidentally, this action also blocks the effects of THC, which is why people who use CBD don't "get high."
The mild downside to the use of CBD is that it absorbs poorly. That's why the directions on containers of CBD instruct people to "apply liberally" to the painful, affected area. Once absorbed, however, it functions quickly.
Uncomfortable side effects are uncommon, and they include fatigue, diarrhea, and possible weight gain. Most people, however, tolerate CBD well. Because it is nonpsychotropic, it also doesn't have a "come down" period that results in possible dysphoria. The general consensus is that it works and is fairly safe, but scientists also state that more research is needed to understand its effects fully.
People should consult their doctors before using CBD as they should with any new treatment. There might be drug interactions and possible allergic reactions that could be detrimental, or even catastrophic, to someone's health.
