Sure has. I contend there's something to be said about reverse tolerance buildup between individual strains
Interesting theory. Unlike the initial reverse tolerance I always feel something from a new kava, and almost always fairly strongly. Just never seems to be representative off what the kava really has to offer. Kava: she's a mysterious lady.
It's almost as if the body is conditioned to the previous chemotype and grabs most strongly what was dominant in that strain. I'd have to conduct more science to confirm, which I am willing to do for the good of Kava Forums, of course.
In all seriousness, I keep on hand a few strains and tend to rotate through them, changing at each new batch. This conversation makes me think I''d get more goodness out of riding one horse at least a couple times. Any thoughts?
