This post is an informative piece on one of my favorite medicinal mushrooms, Reishi. I use it for immune support and mood support, as many of my teachers and herbalist friends have described it as "grounding". In fact, it is often used herbally as an adaptogen. An adaptogenic plant or mushroom is one that is used as a tonic, a restorative, to bring the body back into a balanced state.
Below is a more in depth look at the mushroom, medicinally and otherwise.

Other common names: ling chi, ling zhi (Chinese for "tree of life mushroom"), the panacea polypore.

Natural Habitat/Distribution: This saprophytic mushroom is found on a wide range of hardwoods. It is found throughout the world, from the Amazon to the southern regions of the US and across most of Asia. It is mostly found in warm subtropical regions and less in temperate climates.
Fragrance: Musty, mealy, fungoid. (I am guessing that means it smells like a mushroom.)
Natural Method of Cultivation: Being a saprophytic, I know from PSMS class that it is one of the kinds of mushrooms that can be cultivated. Indeed, Stamets states that it grows well on logs, stumps, and buried blocks of sawdust spawn. (The book is a great resource of you are thinking about cultivating mushrooms.)
Season and Temperature Range for Mushroom Formation: Summer to early fall. Temperature 60-95 degrees F.
Medicinal Properties: Stamets cites studies showing that reishi is a direct antimicrobial, but is not anti-tumor as many other mushrooms have shown to be. He points out that it is helpful for cancer patients by stimulating the production of macrophages, activating the host's production of natural killers cells, T cells and tumor necrosis factors. Many of the over 100 distinct polysaccharides and triterpenoids identified in the reishi mushroom demonstrate immunomodulatory properties.
