In the United States, Coriolus versicolor is classified as dietary supplement by the FDA and most bottlers or manufactures do market their products as dietary supplements. Therefore, these products are not intended to diagnose, treat, cure, or prevent any disease.
There are various different forms of Coriolus versicolor products on the market to buy. These range from grounded mushroom fruit bodies (very low end product) to high quality PSK & PSP (100% extraction from Coriolus versicolor mushroom mycelia). The extraction process and the Coriolus versicolor strain used for the extraction vary greatly between different manufactures and price is not a good indicator what is effective and what is not.
