The highest concentration of CBD can be found in the whole hemp plant (cannabidiol can’t be pressed or extracted solely from hemp-seeds). Currently, there are no documented studies that show undesirable effects from CBD, which is why this particular cannabinoid is legal worldwide. There are, in fact, many studies showing Cbd organic oil to cause only desirable, healthy effects. From the Hemp Plant (Not Marijuana) so PuRx7's CBD is 100% Drug/THC Free! (That means NO dangerous side effects!)
