Shiitake Mushrooms
Also known as: Xiang Gu, Fragrant Mushroom, Lentinula edodes, Dong Gu (dried winter mushroom)
Shiitake are the most important mushroom in Chinese and Japanese cooking — rich, savory, and deeply umami, with a meaty, satisfying texture and a woody, earthy fragrance that perfumes everything around them.
Fresh shiitake are excellent; dried shiitake are even more intensely flavored and produce a soaking liquid that is one of the great natural stocks in Chinese cooking.
In Chinese cuisine, dried shiitake (particularly the prized thick-capped 'dong gu' or winter mushrooms) are a luxury ingredient used in the most refined preparations.

They are used to tonify Qi, nourish Blood, support immune function, and benefit the Stomach.

Modern Scientific Research
Shiitake are among the best-researched medicinal mushrooms. Lentinan, a beta-glucan extracted from shiitake, has been studied extensively as an immune modulator and is used as a cancer adjunct therapy in Japan.
Research shows shiitake consumption supports immune function, lowers LDL cholesterol (from eritadenine content), and provides cardiovascular benefits.
Shiitake contain ergothioneine — a potent antioxidant — and are among the few plant sources of vitamin D when sun-dried.
