The intriguing thing about the polysaccharopeptide (PSP) extracted from Turkey tail mushrooms, is the possibility that it might kill stem-like PCa cells.
In advanced PCa, some cells develop stem-like qualities. The term "progenitor cell" is often used:
These cells are difficult to kill, & conventional therapies don't even tarket them. For instance, they are not dependant on androgen.
Here is the key paper on PSP & PCa:
Some might recall a vitamin E thread where I made a case for using DeltaGold, from annatto. It contains only delta & gamma tocotrienols. It should be used without any other E product, since tocopherols out-compete for uptake. Delta & gamma tocotrienols are the most beneficial of the 8 forms of vitamin E, for CVD & PCa, respectively.
The authors of the PSP study also did a gamma tocotrienol study, followed by a study that showed synergy between the two:
I have very little faith in turkey tail supplements. I live in the U.S. but buy from the Netherlands:
