just heard of this myself, been wanting to ask the same question myself, and looking for more info or some personal references. i did read up on this a bit and the guy ( a professor and researcher } out in Washington state sounds on the fringe of things but also sounds pretty knowledgeable on all kinds of mushrooms is recommending this mushroom for people with ms. the down side is that he owns a company that sells mushrooms....soooo. ????? i think the name of the company is fungi perfecti.

Don't take it till you research it. Isn't a mushroom considered a fungus?

I look up it is good for brain function capsule form be best for me

It is a mushroom that you fry and eat or can buy in capsule form helps with brain function

to tell you the truth I never heard of it but will gladly look into it on the internet. Sometimes I find a good cup of brewed coffee will help if I drink it earlier in the day.
