I could try Valerian - many health food stores around to buy the bulk herb. I used to study herbs and learned to carefully make teas different ways, not touching metal, etc.

What is the best way to take Valerian? It's the root you want right, so then you have to boil the root for some time? Different than making teas with leaves and flowers where you don't want to bring them to boil, just steep.

What about capsules of the powder root or tincture, do you know?
