Researchers isolated a new oyster mushroom strain and studied how it affects digestive system health. They compared the fruiting body and mycelium (root-like structure) and found that water extracts of the fruiting body were rich in beneficial compounds like β-glucans and antioxidants. When tested on stomach muscle tissue, these extracts caused muscle contractions in a dose-dependent manner, suggesting potential benefits for digestive function. This discovery could lead to new natural supplements supporting gut health.
