This research explored compounds produced by the medicinal mushroom Irpex lacteus, which has been traditionally used in Chinese medicine. Scientists discovered 15 new chemical compounds that had never been seen before. While these particular compounds didn’t show the blood vessel relaxation effects they were testing for, this research helps us better understand the chemistry of medicinal mushrooms. Impacts on everyday life: • Advances our understanding of traditional medicines and how they might work • Helps identify new chemical structures that could lead to future drug development • Demonstrates the ongoing potential of natural products as sources of new medicines • Supports the scientific validation of traditional medicinal mushroom uses • Contributes to the growing field of fungal natural products research
