I've learned over the years from qualified herbalists that the best way to ensure that you are getting the exact herb you want, without any nasty fillers, is to get the herb in bulk or grow them yourself if you can. Using herbs fresh is the best way as it is the most potent. Dried herbs last usually for a year, perhaps longer if you store it properly. I love mountainroseherbs.com for buying bulk organic herbs. Hope this helps for anyone who needs it!
