Flavokavain B is a flavokavain found in the kava plant. [1] In 2010 a paper was published identifying it as a glutathione-depleting hepatotoxin. [2]

FKB is said by enthusiasts to occur at higher concentrations in "tudei" kava strains, which are generally considered less desirable.

Yangonin is one of the six major kavalactones found in the kava plant. It has been shown to possess binding affinity for the cannabinoid receptor CB1 (Ki = 0.72 μM), and selectivity vs. the CB2 receptor (Ki >10 μM) where it behaves as an agonist. The CB1 receptor affinity of yangonin suggests that the endocannabinoid system might contribute to the complex human psychopharmacology of the traditional kava drink and the anxiolytic preparations obtained from the kava plant.

Methysticin is one of the six major kavalactones found in the kava plant. Research suggests that methysticin and the related compound dihydromethysticin have CYP1A1 inducing effects which may be responsible for their toxicity. Additionally, methysticin has been shown to potentiate GABAA receptor activity, contributing to the overall anxiolytic profile of the kava plant.
