RESUMEN
Garlic (Allium sativum) has been known for its potent medicinal activities and its interesting culinary role since ancient times. With over 200 phytochemicals and flavoring compounds elucidated and many others yet to, garlic promises to improve human health and vitality. Just like other phytochemical classes, essential oils for garlic have been reported to show interesting medical activities delving across diverse antimicrobial, cardio-protective, anti-cancer, anti-Alzheimer, anti-diabetic, and immunomodulatory activities. Garlic essential oils contain mainly volatile and non-volatile allyl-sulphur-based compounds, which are a product of the stream decomposition of Allicin (a major component of garlic extract). Although a lot of work has been done on Allicin, there is little substantive work on the bio-availability and toxicities of its essential oil. This study, however, reviewed the methods that in recent times have been used to extract essential oils from garlic, recent studies on composition and therapeutic activities of Garlic essential oils, and a predictive overview of their bioavailability and toxicity. Finally, recommendations for future studies and other interesting prospects of garlic were also highlighted.Copyright © 2022
