“Duanwood” is not a specific type of wood but actually a trademarked term by Dragon Herbs. They have done a great job promoting “Duanwood Reishi” as being top quality.
But what does it really mean?
According to their website: “Duanwood means “original wood.” The Reishi is grown on logs cut wild from the forest. The logs are from the same trees that Reishi grows on in the wild, producing the most potent Reishi.”
So Duanwood actually means reishi grown on wood logs, and the vast majority of reishi grown in China already is log grown. Reishi grows on different species of hardwood trees, so the actual wood log used will vary.
Our reishi mushrooms are grown on locally sourced beech wood.
