This study examined four types of edible mushrooms to see if they could protect against aging and fight harmful bacteria. Researchers gave mice an aging-inducing substance and then treated them with mushroom extracts. The mushrooms, particularly Lion’s Mane (Hericium erinaceus), helped prevent brain and liver damage, reduced inflammation, and showed antibacterial effects against multiple bacterial strains. These findings suggest mushrooms could be useful natural supplements to promote health and combat age-related decline.
