Our Turkey Tail Mushrooms are cultivated on hardwoods logs in the remote woodland of Coed Talylan, on the western edge of the Brecon Beacons, Wales. Once harvested they are dried in sterile conditions and frozen in order to remove any potential contamination. You will find that many other sources of medicinal mushrooms sold online are imported from China. Unfortunately, there is no way of guaranteeing the quality of these imports. Although we are not as yet registered as Organic we can assure you that the whole process of cultivation uses only organic inputs and the mushroom fruit bodies are grown in a pristine native broadleaf woodland.
