I have dried Fomitopsis betulina, also known as the Birch Polypore for sale. 2.5 oz. 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.
All of my items are shipped via USPS Priority Mail.

Dried in a vacuum sealed bag.

Keep in a dry jar/container.

You can pulverize it and take it as powder form, make a tea from it, create a double extract from it, and more!
