Kava is able to increase dopamine levels in the nucleus accumbens [2] and desmethoxyyangonin likely contributes to this effect. This, along with several other catecholamines, may be responsible for the purported attention-promoting effects of kava.
Kavain has anticonvulsive properties, attenuating vascular smooth muscle contraction through interactions with voltage-dependent Na + and Ca 2+ channels. [1] How this effect is mediated, and to what extent this mechanism is involved in the anxiolytic and analgesic effects of kavalactones on the central nervous system, is unknown.
Yangonin is one of the six major kavalactones found in the kava plant. [1] It has been shown to possess binding affinity for the cannabinoid receptor CB 1 (K i = 0.72 μM), and selectivity vs. the CB 2 receptor (K i >10 μM) where it behaves as an agonist.
