Wild Ganoderma is very rare and is difficult to collect. Even if someone finds it by chance, its effects are always lost because of aging,. It becomes hard like leather. They may also be toxic. Since they are haphazardly collected, quality control is impossible.
In 1970, a technician of Kyoto University Foodstuff Scientific Research Institute, Mr. Yukio Naoi, used ‘Spore Separation Cultivation Method’ to successfully cultivate Ganodermas. This method was introduced in the Republic of China in 1975. Since the climate and soil conditions are ideal, this technique has been widely adopted.
