The seed is used. You can make tea or tincture. These bags are for liquid storage and are quite handy and wonderful. They come with a spigot that you slip in after the bag is full. They are heavy duty, made with 4 layer welded laminate of 2 outer layers of nylon and two inner layers of Linear low density polyethylene.
Life expectancy is years.
They weigh only 2 oz. They are reusable and are very handy and it is a good idea to have some extra water put up. Keep a full one in your trunk. The neat thing about these is that they are small, easy to carry and will store well. These are not on the Internet site, just add them to your order with the special button.
