Raphael Mechoulam, the man who discovered THC and CBD, conceived the concept of Entourage Effect. Raphael suggested that cannabis compounds like CBD function better when mixed. Meaning, the right cannabis extract should be more effective than the CBD by itself. The full-spectrum CBD oil is an astonishing high-quality product proposed for oral use only. It is 100% natural and is exclusive of any herbicides, pesticides, artificial fertilizers, and harmful chemicals. The product comes with a spray bottle, and that makes taking CBD oil very easy and mess-free. For better results, it is instructed to use one spray each day and leave the oil underneath the tongue to soak for at least sixty seconds before intaking water.
