Kava FAQ Why does kava just not really work sometimes? Also, can you develop tolerance to specific strains?

[The Kap'n]

Isit possible that some parts of the root are just lower in kavalactones? Maybe when it doesn't work properly it's just down to being unlucky and you've used root from the bag that's lower in kavalactones. Probably not but just a thought.

Actually, you're more correct here than you may realize. Natural fluctuations in potency are directly related to specific plant parts, age, and the processing method.
