Ganoderma Extract
Ganoderma is not often used in cooking because they are hard and have a bitter taste, although some people do use them in the same dishes that you might use Shiitake mushrooms (Lentinula edodes). But you are unlikely to find them at your favorite market. They are mainly used for purely medicinal purposes and have a number of health benefits. In fact, it is known among practitioners of Chinese medicine as the king of herbs.
