Ajoene is a sulfur-containing compound derived from garlic (Allium sativum) and has garnered scientific interest due to its antimicrobial properties. Several in vitro studies have shown that ajoene exhibits antibacterial activity against both Gram-positive and Gram-negative bacteria, including some antibiotic-resistant strains such as methicillin-resistant Staphylococcus aureus (MRSA). The mechanism is thought to involve disruption of bacterial cell membranes and inhibition of quorum sensing, which impairs bacterial communication and biofilm formation. Additionally, ajoene has demonstrated synergistic effects when used in combination with conventional antibiotics, potentially enhancing their efficacy or helping to overcome resistance.

However, while laboratory research is promising, robust clinical trials in humans are lacking. Most current evidence comes from cell culture or animal studies, and the translation of these effects into clinical practice is yet to be fully established. Traditional medicine systems have historically used garlic for infections, but the focus specifically on ajoene is recent and science-driven rather than based in folk tradition. Thus, while ajoene is not a direct alternative to antibiotics, it may serve as a supportive agent or adjuvant in antimicrobial therapy, pending further clinical validation.
