💊 Medicinal Uses

Rich in lentinan, a beta-glucan polysaccharide with significant immunomodulatory and antitumor properties. Used as an adjunct in cancer therapy (especially gastric) in Japan and China. Contains eritadenine which lowers cholesterol. Antiviral, antibacterial, and liver-protective. Eritadenine helps prevent platelet aggregation. High in vitamin D when sun-exposed.

📜 History & Traditional Uses

Cultivated in China for over 1000 years. First cultivated on logs during the Song Dynasty (960–1127 CE). Known as 'xiang gu' (fragrant mushroom) in Chinese. Japanese developed modern log cultivation methods in the 1930s. Now second most cultivated mushroom globally after button mushrooms.

📝 Notes

Inoculate freshly cut hardwood logs (3–6 inch diameter) with plug spawn in spring. Keep logs in shady, humid location. Fruiting triggered by soaking logs and temperature fluctuations. Each log can produce for 3–5 years. Shiitake has a rich umami flavor; removes stems before cooking (they're tough). Sun-dried shiitakes have enhanced vitamin D.
