Allicin is widely recognized for its strong 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 fight infections. Due to its antifungal activity, allicin is applied in treatments for fungal skin conditions and candida overgrowth. In agriculture, it serves as a natural pesticide and antifungal agent for crop protection. Research also explores its potential in cardiovascular health, where it may help lower blood pressure and reduce cholesterol levels. Additionally, allicin exhibits antioxidant effects, contributing to cellular protection and reducing oxidative stress. Its bioactivity makes it a subject of interest in pharmaceutical and nutraceutical development.
