Shitake Mushroom Extract

One shiitake extract called lentinan is a beta glucan. This is a type of complex sugar compound. Beta glucan is believed to stimulate the immune system and trigger certain cells and proteins in the body to attack cancer cells. In laboratory studies, it seems to slow the growth of some cancer cells.

In mice, lentinan has been shown to stop bowel cancer cells growing. In laboratory tests, the protein part of lentinan (lentin) can stop some fungal cells growing. It can also stop leukaemia cells dividing. 

Some Japanese researchers give lentinan along with chemotherapy to treat patients with lung, nose, throat, and stomach cancers.

More clinical trials are currently under way to understand which compounds in shiitake mushrooms might work as cancer treatments.
