A CBD tincture is a preparation made from CBD extract. It is used orally (swallowed) and sublingually (under the tongue). When used sublingually, CBD can be absorbed directly into the bloodstream via capillaries found in tissues in the mouth. When consumed orally it must pass through the digestive system, but it is also absorbed via the lining of the stomach.
CBD oil can have a wide variety of effects on the human body, most of which are subtle. However, CBD is known to be a powerful anti-inflammatory and has been reported to reduce pain, swelling and stiffness. It has also been shown in research studies to improve circulation and help to regulate a variety of systems, including the immune system, the nervous system, the endocrine system, the cardiovascular system, the digestive system, the heart, liver, kidneys and others.
