Researchers isolated and studied a compound called β-D-glucan from puffball mushrooms (Lycoperdon pyriforme) that have been traditionally used to heal wounds and stop bleeding. Laboratory tests showed this compound safely promotes the movement and growth of skin cells that help wounds close without harming red blood cells, and it actually helps blood clot faster. These findings support the traditional use of this mushroom and suggest it could be developed into a new natural wound-healing treatment.
