Full-spectrum oil is the closest to whole plant medicine. It includes all of the cannabinoids, terpenes, and flavonoids naturally found in the hemp plant. Broad-spectrum oil is similar to full-spectrum oil, except that is does not include the cannabinoid, THC. Isolate is the isolated molecule of CBD. Isolate is not an oil, but a fine, white powder, comprised of 99% CBD, 0% THC.
