The association of fish oil and CBD enhances their anti-inflammatory effects, which occur at lower doses (20 mg and 0.3–10 mg/kg, respectively) than the per se administration of the two substances; these findings were reported in mice with induced colitis, in which the combination of fish oil and CBD decreased the myeloperoxidase (MPO) activity, DAI score, intestinal permeability, and levels of IL-1β and IL-6 [73]. The gene discussed is MPO; the disease is colitis.
