With a grinder you can powder them and make tea or a tincture. If you cannot grind them you could add some of the roots (1:5 -weight/volume) to some good brandy and let it sit for several months. The roots will soften and the brandy will become darker and infused with the Ginseng constituents. You can eat the roots a little at a time and take the Ginseng Cordial when you need some.
