Idk about chamomile but valerian root will hit you like a Xanax if you take it like it's real medicine. Whatever you steep in a cup of tea is going to be fairly weak. You're looking for a concentrated extract or tincture you can eyedropper into a drink. I have found it in stores with very large vitamin sections (expensive) and in little Russian groceries (cheap).

That said, if you take it this way you do need to treat it like real medicine. It can be addictive. There are side effects (I wake up with headaches f I go ham.) There are drug interactions. Of course, dosages aren't regulated in the USA. I never had capsules that seemed to work. I figure the tinctures must stronger or easier to absorb.
