Cannabidiol [pronounced CAN-uh-BID-ee-all] is the active ingredient found in Cannabiva Full Spectrum CBD oil, Broad Spectrum CBD oil, and Zero High Pure Isolate CBD Oil. CBD is short for Cannabidiol, a non-intoxicating derivative from the cannabis sativa plant. CBD is just one of numerous pharmacologically active compounds called cannabinoids that can be extracted from cannabis. Cannabinoids like CBD bind to special receptors in the body to promote benefits. Together, this biological network of receptors make up what is known as the endocannabinoid system, or the ECS. The ECS is important because it regulates essential functions in the body.
