There is no good, easy, otc med. I've said before and I'll say it again; herbs such as valerian, st. John's, skullcap, catnip and kava-kava, etc. Can have an effect, but not if you buy them at Walgreens, GNC, or other places likes that; they will not have an effect because they are not of high quality. I have had positive effects, especially from Kava-Kava and Valerian root but both were purchased very fresh, bulk and of high quality. Buying some capsules at the store never works, you can take a bottle of it and just get a tummy ache. But properly prepared fresh Kava infusion (it needs fat and heat and to be ground fine) in a solution to drink, Valerian can feel just as strong as any benzo a few times It requires a lot of fresh root powder prepared in a hot tea.
So no, there is no such thing as an easy OTC anxiety med.
