Cannabinoids, such as CBD, attach themselves to specialized receptors in a person’s brain and immune system. One of these receptors, called a CB2 receptor, plays a role in the immune system by managing pain and inflammation.
Researchers believe that when CBD enters a person’s body, it may attach to CB2 receptors. Alternatively, it may cause the body to produce natural cannabinoids that attach to the CB2 receptors. Either way, scientists think CBD affects the way that these receptors respond to the signals that they receive, possibly helping reduce inflammation and pain
A gluten-free diet, weight loss and swimming also can reduce symptoms.
