Does the 4:1 extract have higher contents of the active ingredient? Paradise Herbs often says their extracts are 10:1 or even 20:1 but they don't feel like they're more potent, not even 2x as potent as a regular extract, for other herbs I mean. So I'm skeptical that 4:1 actually means something.
Yeah, I also find it beneficial for general anxiety. Not sure about sleep though.
Have you noticed any apathy from chronic use? It also seems to make me a bit hazy, like distant from the current experience.
