i'd stay away from tinctures if they have alcohol, IMO. i tried em before i knew better, honestly, and I didn't really get any good effects compared to root powder and it also upset my stomach. Those kind just aren't good for your body. With what you're probably spending on the tincture I'm guessing you could get anywhere from 1/4 - 1 lb. of quality root powder. Good luck finding something that works for you!
