An increasing number of researches and studies show that cannabinoids (hereafter cited with the collective term CBD) have positive effects on a wide range of conditions and diseases. But because CBD isn’t a registered medicine, it has to be considered as a foodsupplement. However, the results are so positive and convincing that the medical effectiveness of CBD can’t be denied anymore. On this page you can read all about CBD.

On this page we have compiled an alphabetical summary of conditions with links to studies in which the effects of CBD have been researched. The majority of the studies are published by the American governmental institutions NIH (National Institutes of Health), NLM (National Library of Medicine) en NCIB (National Center for Biotechnology Information). The website Cannabinoid Medicines also contains lots of additional scientific information.

Important to know

The endocannabinoid system

The endocannabinoid system (ECS) is a group of endogenous cannabinoid receptors located in the mammalian brain and throughout the central and peripheral nervous systems, consisting of neuromodulatory lipids and their receptors. Known as “the body’s own cannabinoid system”, the ECS is involved in a variety of physiological processes including appetite, pain-sensation, mood, and memory, and in mediating the psychoactive effects of cannabis.

Two primary endocannabinoid receptors have been identified: CB1 and CB2. CB1 receptors are found predominantly in the brain and nervous system, as well as in peripheral organs and tissues, and are the main molecular target of the endocannabinoid ligand (binding molecule), Anandamide, as well as its mimetic phytocannabinoid, THC. One other main endocannabinoid is 2-Arachidonoylglycerol (2-AG) which is active at both cannabinoid receptors, along with its own mimetic phytocannabinoid, CBD. 2-AG and CBD are involved in the regulation of appetite, immune system functions and pain management

The studies

Although there already is quite a lot known about the effects of CBD, research is still in its infancy. Many of the studies below are orientating, documentary or pre-clinical.
