There is a choice when using CBD oil, full-spectrum, or isolate, this is the difference between using a single compound or whole CBD rich plant extract. Since the endocannabinoid system has the most receptors of any in the body using full-spectrum CBD oil has higher efficacy results because it acts on all those receptors. Isolating a compound may sound like it is a more pure version but it has limited benefits because it acts on only a portion of the receptors in the endocannabinoid system. Whole plant extract widens the therapeutic effect and is never diluted like isolated versions of CBD oil. Full-spectrum CBD oil acts on all receptors in the largest signaling system in our body. Again, this why CBD can improve so many different seemingly unrelated conditions.
