Cannabidiol (CBD) is the main non-psychoactive compound found in the cannabis plant. It has many molecular targets that involve its activity with many physiological pathways. Unlike THC, it is not psychoactive and does not produce a "high" sensation. In fact, CBD has the potential to act as a THC buffer, meaning that it can mitigate the psychoactive effects of THC. CBD is typically extracted from the hemp plant, which contains only trace amounts of THC. It can also be extracted from CBD-producing cannabis strains and found in medical marijuana products. 

CBD products are often identified as "full-spectrum" or "broad-spectrum." Full spectrum means that there may be trace amounts of THC along with other cannabinoids, whereas broad-spectrum refers to CBD products with no THC at all. 

CBD has a range of potential therapeutic benefits, including pain relief, reducing anxiety and depression, improving sleep quality, and reducing inflammation. It works by interacting with the body's endocannabinoid system. In fact, CBD has been identified as a pleiotropic molecule, meaning it works through many biochemical pathways, including over 65 molecular targets. 

Studies have shown that CBD has the potential to reduce seizures in people with epilepsy, and it is approved by the U.S. Food and Drug Administration (FDA) for this purpose. CBD has also been shown to have anti-inflammatory properties and may help treat autoimmune conditions and others, such as arthritis, multiple sclerosis, and inflammatory bowel disease.
