I bought goldenseal powder and was wondering how i'm suppose to use it? like i tried a little bit drinking with water.

Why are you using it: How you use it depends on why you are using it- goldenseal can be applied topically, used as a mouthwash or taken internally. It is a powerful natural antibiotic and should be taken for short times for specific reasons, not regularly or casually. See http://www.Herbwisdom.Com/herb-goldenseal.Html ; http://www.Livestrong.Com/article/409276-dosage-of-goldenseal-root/ for more info on proper use.
