The ABM mushroom to be 80% more effective than the world's number one cancer drug PSK

The ABM mushroom was tested at the Tokyo University National Center Laboratory and the Tokyo College of Pharmacy. Compared to the other commonly used mushrooms—including maitake, reishi, and shiitake—ABM exhibited far superior immune enhancing effect. This trial showed ABM to be 80% more effective than the world's number one cancer drug PSK, an extract of Coriolus Versicolor. ABM was found to contain far higher levels of beta glucans than maitake, shiitake, and reishi.
