This is a massive ‚Fomitopsis betulina‘ (Birkenporling / birch polypore) we found in summer 2020. I never saw a bigger one. It‘s diamter was around 37cm. This is one of the healthiest and most healing mushroom in northern Europe. It has been researched for its phytochemistry and pharmacological activity. Phytochemicals include phenolic acids, indole compounds, sterols, and triterpenes. You maybe know this one cause ‚Ötzi, the Iceman‘ carried this mushroom in his pocket. So we see it‘s medical usage was known over 5000 years ago which is amazing. There is so much we don‘t know. We consume this mushroom as a tea for a kind of juice fast and cleanse for 20 days. This boost for example the immune system and regulates many other things in your body. As the name says it grows mostly on birchs.
