Ganoderma is a medicinal mushroom that has been used in traditional medicine for thousands of years and is now being studied for its ability to fight infections. The mushroom contains special compounds like polysaccharides and triterpenoids that can kill harmful bacteria and fungi in multiple ways—by breaking down their cell walls, stopping them from reproducing, and boosting your immune system. Scientists have found that Ganoderma works against many dangerous bacteria including antibiotic-resistant strains, and it may offer a natural alternative to conventional antibiotics as antibiotic resistance becomes a major global health problem.
