I have dried Fomitopsis betulina, also known as the Birch Polypore for sale. This mushroom is medicinal. It is known to be used as an antiseptic to clean wounds and promote healing, a plaster that is microporus, antifungal and is believed that it was used by the Bronze Age man to get rid of parasitic worms.
I sell various liquid cultures, inoculated substrates, and dried mushrooms. Any questions feel free to message me!
