Antifungal and antibacterial activities of allicin: A review

During the past two decades, much attention has been focused on the antibacterial and antifungal potential of allicin against multi-drug resistant microorganisms. Despite promising in vitro results, the in vivo activity of allicin has not yet been well documented in preclinical and clinical efficacy trials. Due to some adverse effects, further studies are required to confirm the potential therapeutic use of allicin as an antimicrobial agent. Pharmacokinetic studies should be performed in order to improve the bioavailability of allicin by employing different delivery systems.
