Shiitake - Cultivation History

Cultivation History

Shiitake are native to Japan, China and Korea and have been grown in all three countries since prehistoric times. They have been cultivated for over 1,000 years. The oldest record regarding the shiitake mushroom dates back to CE 199 at the time of Emperor Chūai in Japan. However, the first written record of shiitake cultivation can be traced to Wu Sang Kwuang in China, born during the Sung Dynasty (AD 960–1127).

During the Ming Dynasty (AD 1368–1644), physician Wu Juei wrote that the mushroom could be used not only as a food but as a medicinal mushroom, taken as a remedy for upper respiratory diseases, poor blood circulation, liver trouble, exhaustion and weakness, and to boost qi, or life energy. It was also believed to prevent premature aging.

The Japanese cultivated the mushroom by cutting shii trees with axes and placing the logs by trees that were already growing shiitake or contained shiitake spores. Before 1982, the Japanese variety of these mushrooms could only be grown in traditional locations using ancient methods. In 1982, Gary F. Leatham published an academic paper based on his research on the budding and growth of the Japan Islands variety; the work helped make commercial cultivation possible in the United States.
