Ajoene
Synopsis of ajoene
Ajoene is a sulfur-containing compound derived from garlic (Allium sativum), formed primarily when garlic is crushed or chopped and allowed to sit, triggering the enzymatic conversion of alliin to allicin, which further breaks down into various sulfur compounds—including ajoene. It exists in two structural forms (E-ajoene and Z-ajoene), both of which have demonstrated significant biological activity. Unlike the volatile and short-lived allicin, ajoene is more stable, especially in oil-based preparations, and is found in aged or macerated garlic extracts.
Ajoene has attracted scientific interest for its broad range of potential therapeutic properties. It exhibits antimicrobial, antifungal, antiviral, antithrombotic, anti-inflammatory, and anticancer effects in various in vitro and in vivo models. One of its most recognized actions is its ability to inhibit platelet aggregation, making it a natural blood thinner and potentially useful in cardiovascular health, especially for preventing clot-related events such as stroke or heart attack.
Its antifungal properties are particularly effective against Candida species, and it has shown activity against bacteria like Staphylococcus aureus and viruses including HIV in early laboratory studies. Ajoene also interferes with tumor cell proliferation and induces apoptosis, positioning it as a compound of interest in cancer research. Its ability to block thiol-containing enzymes and modulate signaling pathways such as NF-κB and MAPK supports its anti-inflammatory and immune-modulating potential.
Ajoene is generally consumed through garlic oil preparations or specially formulated supplements. Because it is less abundant than other garlic sulfur compounds and not present in raw garlic in its final form, standardization in supplements is key for therapeutic use.
Historical Use:
While ajoene itself was not known in ancient times—its identification and structural analysis occurred in the 1980s—its source, garlic, has an extensive historical legacy in herbal medicine. Garlic has been used for over 5,000 years across various cultures for its antimicrobial, cardiovascular, and immune-boosting properties. In ancient Egypt, Greece, India, and China, garlic was revered as a medicinal food and was commonly used to treat infections, digestive issues, respiratory ailments, and circulatory disorders.
Many of the benefits historically attributed to garlic—such as resistance to infection, cleansing the blood, and promoting longevity—can now be linked to its organosulfur compounds like ajoene, allicin, and diallyl disulfide. Though early herbalists were unaware of ajoene’s existence, they understood that crushed or aged garlic had stronger effects, likely due to the natural chemical transformations that occur upon processing.
In this sense, ajoene represents a scientific validation of ancient garlic-based therapies, highlighting how specific compounds contribute to the plant’s traditional uses. Its identification and study demonstrate how modern research continues to uncover and refine the pharmacological basis of time-tested remedies, transforming a staple of folk medicine into a compound with promising clinical applications.
