Allicin is widely recognized for its potent antimicrobial properties, making it effective against bacteria, viruses, fungi, and parasites. It is commonly used in natural health products and dietary supplements to support immune function and help prevent infections. Due to its antifungal activity, allicin is applied in treatments for fungal skin conditions and candidiasis. In agriculture, it serves as a natural pesticide and antifungal agent for crop protection. Additionally, allicin exhibits antioxidant and anti-inflammatory effects, contributing to cardiovascular health by helping lower blood pressure and reduce cholesterol levels. Research also explores its potential in cancer prevention due to its ability to induce apoptosis in certain cancer cells.
