This is probably the most asked question from people who are not familiar with the substance. CBD is one of many compounds in cannabis plant. Many times, CBD is sold in concentrated oil form. Yes, it comes from the same plant where marijuana comes from.
CBD, as well as other cannabinoids, work by attaching itself to certain receptors such as CB1 and CB2 in human body; the human body actually has specific receptors for these because it produces certain cannabinoids on it own.
CB1 receptors are present throughout the body, but they are mainly populated in the brain. They deal with coordination and movement, pain, emotions, mood, thinking, appetite, memories, and other functions. THC attaches to these receptors, creating a high for the users.
CB2 are more common in the immune system, which affect inflammation and pain. CBD was thought to attach to CB2 receptors, but now it appears that it does not attach directly to either receptors; it is thought to direct the body to use its own cannabinoid.
CBD has been the latest craze, and the studies suggest more and more benefits of CBD in medical fields as we get to know more about the substance.
