Since this is a section on the forum where we are allowed some liberties I'll take the contrary opinion. (sorry Gary)

Many mushrooms have been researched with respect to health benefits. We are asked not to link web sites here except to reference areas (not to organizations selling products) If you do a Google search on "mushroom cancer" you will come up with many interesting and serious discussions around some mushrooms and their suspected benefits. This is just one:

Gary you might read the chapter 10 conclusions.

I will say this (and expect to get flack for it) that research on a naturally grown cure will likely be limited. The reason is simple; you cannot profit from something easily grown.

This is an area where I do NOT think Quack Watch has explored. Quack Watch regularly lists anything that attempts to make a profit from suceptable (seriously ill) people. I have no serious gripe with them except that they paint with a very wide brush.

The bottom line is if an edible substance is thought to help with cancer I see NO reason not to try it. (Except if it is expensive and overly hyped) I ate more than a few pounds of Shiitake mushrooms and splurged on pills (I will not name publicly) that were mushroom based. I do NOT claim that it cured my cancer, but no one can say it didn't help.
