Palmitoylethanolamide is an endogenous cannabinoid. Palmitoylethanolamide is a weak ligand of the cannabinoid 1 (CB1) and cannabinoid 2 (CB2) receptors. It has been found that Palmitoylethanolamide can inhibit fatty acid amide hydrolase. Palmitoylethanolamide exhibits anti-nociceptive, anti-inflammatory, anti-convulsant and immunosuppresant activity. Palmitoylethanolamide acts by binding to an unidentified cannabinoid receptor that is similar to CB2.
