Recent research shows that a lot of pure CBD may not be so good for women's reproductive health. The literature also shows that it treats very few conditions compared to full spectrum oil, even CBD dominant (99%+) oil is better than pure CBD.
I'm not sure what the "pure CBD" craze is...you're not any more "pure" than a stoner because CBD isn't psychoactive. Too much isolates probably aren't the best way to balance the endocannabinoid system, especially ones made from pesticide-ridden industrial hemp.
Also, you keep talking about the endocannabinoid system, but CBD has very low affinity for the cannabinoid receptors, so THC which mimics anandmide is the better example of an endogenous ligand of the ECS.
