The cannabis plant contains hundreds of different phytochemicals including cannabinoids, terpenes, and other compounds. Full spectrum CBD or hemp oil generally refers to products that not only contain CBD but contain the other plant molecules as well. This version of CBD oil is minimally refined, leaving most of the cannabinoids and terpenes intact and in the oil.
Full spectrum, sometimes also called “whole plant,” means the full plant extract is included. Full spectrum provides more of the plant’s molecules in ratios and amounts that nature intended.
While there is still more research to be done, there are indications that show cannabinoids and terpenes work together to influence each other. This synergistic effect is called the entourage effect and has seen CBD work with THC to reduce the effects of a high and CBD to influence ones own cannabinoid receptors.
