Simply put, CBD restores homeostasis (the body's natural balance). It works on endocannabinoids by activating two core receptors (known as CB1 and CB2) that regulate mood, body temperature, cognitive function, and muscle repair. Its effects are used to treat a variety of conditions, including anxiety, depression, pain, and menstrual cramps, and it has beneficial effects on concentration, energy levels, and sleep. It is also sometimes used as an anti-inflammatory agent and as a local anesthetic.
