HI Everyone I use 'TY LING' brand crystallized ginger root to aid digestion. It's = imported from China and available at my local super market in the Orienta= l food section. It comes in a 4 oz. box at the cost of apx. $2. It's = very spicy so take only a tiny bite at a time. Good shoping Margie Nestler 62/4 Carnegie, PA.
