Query: Ripoff!

I suffer from GERD and peptic ulcer disease, and ginger really has changed my life. I experience great relief from ginger teas, authentic gingerale, ginger candies, and even just chewing on it fresh; so, I thought GingerForce might work even better. Oh man, was I wrong! This stuff is supposed to be concentrated, but it did not help at all to soothe my stomach or fight nausea. GingerForce provided me no effect whatsoever, unless you count being $18 poorer. Don't waste your money on this when you could get stuff that is effective from your local grocer for a fraction of the cost!
