Mechanism of action

The active kavalactones in kava (particularly kavain and methysticin) interact with multiple CNS targets including GABA receptors, monoamine oxidase inhibition, and calcium/sodium channel modulation. These mechanisms collectively reduce anxiety and promote relaxation. The exact primary mechanism remains incompletely characterized, though GABAergic potentiation is considered a major contributor.
