I have a nervous stomach and usually this salt will settle me down fine. When my stomach is upset due to stress and not food, usually a couple Tylenol taken with this salt remedy will do the trick. I'm from the old school of homeopathy. Unless you really get no relief and suffer "chronic symptoms" the other category is "acute symptoms" which are attacks of sort like headaches from which treatment can bring relief immediately if not permanently. Therefore, I take 6 tablets every 15min or at intervals of attack until symptoms subside.
