Cultivation of this mushroom began in central China in about the 12th century. Early growers figured out to collect spores and insert them in fallen trees and logs to produce more than could be easily collected in the wild. 

Japanese scientist and mushroom researcher Goro Chihara and others did extensive research on the Shiitake mushroom in the 1970's. Through this research it was discovered that they had polysaccharides. Through this process the discovered an active fraction and named it lentinan, which is a pure beta-1-3-glucan. Lentinan compounds have been used to develop a drug that has been used in oncology practices. Shiitake mushrooms also have something called eritadinine, a compound that has been to reduce cholesterol in some studies. 

Our China grown shiitake mushroom extract is made of 100% fruiting bodies and superior to the US lab grown Shiitake which is mycelium that has been grown on grain, which has high levels of starch and low levels of beta-glucan.
