To play DEV-adv' almost everything done in medicine is guess work. give it to mice, did mice die?, are they bleeding from the anus, if we kill it can we tell it's body from another,
what chemical expressions do we see? it can take 20 years for a wild plant or shroom to be tested and put on the market, and millions of dollars, and a rich person that not going to die of boredom waiting to find out. in an age where we all grew up scared of germs and were taught not to even look at the mushrooms it's not suprising that the is very little research. it's actually why i'd love to become a mycologist one day. also it's entirely possible the mice and naturally allergic and we are not to many mushrooms.
