i'd leave it in there more like 2-6 weeks. i don't think 1 week is really ideal.
I have valerian tincture that i made. i went with 6 weeks. works great.
I also have a valerian/calea tincture that is done. i just need to strain it off and try it out.
I assume it will be pretty bitter, but i'm interested in checking out the effects.
