Cannabidiol (CBD) is a naturally occurring compound found in the resinous flower of cannabis, a plant with a rich history as a medicine going back thousands of years. Today the therapeutic properties of CBD are being tested and confirmed by scientists and doctors around the world. A safe, non-addictive substance, CBD is one of more than a hundred “phytocannabinoids,” which are unique to cannabis and endow the plant with its robust therapeutic profile.
CBD is closely related to another important medicinally active phytocannabinoid: tetrahydrocannabinol (THC), the compound that causes the high that cannabis is famous for. These are the two components of cannabis that have been most studied by scientists.
Both CBD and THC have significant therapeutic attributes. But unlike THC, CBD does not make a person feel “stoned” or intoxicated. That’s because CBD and THC act in different ways on different receptors in the brain and body.
CBD can actually lessen or neutralize the psychoactive effects of THC, depending on how much of each compound is consumed. Many people want the health benefits of cannabis without the high – or with less of a high.
How Does CBD Work?
CBD and THC interact with our bodies in a variety of ways. One of the main ways they impact us is by mimicking and augmenting the effects of the compounds in our bodies called “endogenous cannabinoids” – so named because of their similarity to the compounds found in the cannabis plant. These “endocannabinoids” are part of a regulatory system called the “endocannabinoid system”.
The discovery of the endocannabinoid system has significantly advanced our understanding of health and disease. It has major implications for nearly every area of medical science and helps to explain how and why CBD and THC are such versatile compounds – and why cannabis is such a widely consumed mood-altering plant, despite its illegal status.
The endocannabinoid system plays a crucial role in regulating a broad range of physiological processes that affect our everyday experience – our mood, our energy level, our intestinal fortitude, immune activity, blood pressure, bone density, glucose metabolism, how we experience pain, stress, hunger, and more.
What happens if the endocannabinoid system doesn’t function properly? What are the consequences of a chronically deficient or overactive endocannabinoid system?
In a word, disease.
Cutting-edge science has shown that the endocannabinoid system is dysregulated in nearly all pathological conditions. Thus, it stands to reason that “modulating endocannabinoid system activity may have therapeutic potential in almost all diseases affecting humans,” as Pal Pacher and George Kunos, scientists with the U.S. National Institutes of Health (NIH), suggested in a 2014 publication.
By modulating the endocannabinoid system and enhancing endocannabinoid tone, CBD and THC can slow – or in some cases stop – disease progression.
