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 also applied in agricultural settings to protect crops from fungal pathogens, serving as a natural alternative to synthetic fungicides. In food preservation, allicin acts as a natural antimicrobial agent, helping to extend shelf life by inhibiting the growth of spoilage and pathogenic microorganisms. Additionally, it has been studied for its potential cardiovascular benefits, including supporting healthy blood pressure and cholesterol levels. Its anti-inflammatory and antioxidant effects further contribute to its use in managing chronic inflammatory conditions and oxidative stress-related diseases.
