This study compared growing the medicinal mushroom Ganoderma tsugae on sterilized versus non-sterilized larch wood in a forest setting. Researchers found that non-sterilized wood actually produced mushrooms with higher levels of beneficial compounds like triterpenoids and polysaccharides, while requiring less processing and cost. These findings suggest that farmers can use a simpler, less expensive cultivation method while still producing high-quality medicinal mushrooms.
