According to different kinds of ginseng, its shelf life is also different. If it is red ginseng, it is no problem to leave it for two or three years. Red ginseng has a long shelf life and can generally be preserved for five or six years. The shelf life of ginseng is relatively short, usually two to three years. Ginseng is generally white or slightly yellow, and expired ginseng may turn red or yellow because the elements are oxidized.
