I started using Kava Kava (Piper methysticum) again for anxiolysis, mood lift, mild euphoriant and sociability improving benefits.
High quality Kava seems to be quite expensive these days, so I wonder if there is some way to potentiate Kava so you would need to take less, or if there is some other substance that would synergize with it.
I think a teaspoon of black pepper potentiates my instant Kava, but can't say for sure yet. I'll need to experiment more. Years ago I combined Kava with Passion Flower and it seemed to increase the sedative and mood lifting effects.
Feel free to chime in with your ideas, you fellow Kava lovers!
