Full spectrum CBD oil is very different from CBD isolate. We say this because full spectrum CBD oil has CBD and all of the other cannabinoids (including THC), terpenes and fatty acids that naturally occur in the cannabis plant. Full spectrum CBD is often called a full or whole plant extract.
In a full spectrum extract, the oil goes through the cannabinoid extraction process and filtration, however, none of the cannabinoids or other compounds are removed. While full spectrum CBD does have THC, it does not contain enough THC to get you high. It will however likely show up on a roadside mouth swab test.
The benefits of a full spectrum CBD oil is that many of the other chemical compounds and cannabinoids in a full-plant extract have healing properties. For example, the terpenes in the cannabis plant are known to have anti-inflammatory properties. Other cannabinoids found in a whole plant extract are thought to enhance the overall benefits of taking CBD.
In 2005 a study concluded that a CBD oil with a full-plant extract had greater medicinal properties than only CBD. Because the oil has all of the cannabinoids and other chemical compounds, you will get the positive effects of the chemical synergies called the entourage effect.
