CBD oil is any vegetable oil (coconut or hemp oil) mixed with medical cannabinoids (CBD).
It usually comes as a liquid extract in a bottle with a pipette built into the cap. The oil can be dripped under the tongue for rapid absorption into the body's circulatory system or mixed with food/beverages. CBD oil can also be presented as a viscous gel that is used as a dietary supplement. It is useful to know that CBD oil in the form of a gel begins to work only after a certain period of time, because this form of CBD oil takes longer to be absorbed into the body.
CBD oil is commonly used to suppress various symptoms in the body such as pain, anxiety, stress and insomnia.
