When it comes to oral hygiene, most of us reach for that minty, chemical-laden mouthwash without a second thought. However, a recent review from the University of Sharjah reveals a shocking fact. Garlic, the everyday kitchen staple, may soon challenge traditional antiseptics like chlorhexidine for the crown of germ-fighting power. “Garlic has been recognised for its natural antimicrobial properties for centuries,” explain the researchers. “It’s an exciting, herbal alternative that deserves more attention.”

The systematic review, published in the Journal of Herbal Medicine, examined clinical trials comparing garlic extract mouthwash with chlorhexidine. The researchers analysed over 400 studies before narrowing the field to five high-quality trials. The results? Garlic extract, particularly in higher concentrations, can match, and occasionally outperform, chlorhexidine in killing oral bacteria, while offering prolonged residual activity.

Nevertheless, it’s not all that easy. Garlic mouthwash can produce a stronger burning sensation and a distinctive odour, which might make some patients hesitate. Despite these minor drawbacks, the clinical potential is clear. “While chlorhexidine remains the gold standard, concerns about side effects and antimicrobial resistance make garlic a compelling option,” the review suggests.

Garlic mouthwash Is proving itself as a serious contender in oral hygiene. With the right concentration, it can rival synthetic antiseptics, offering a natural, accessible, and surprisingly potent alternative for those keen to explore herbal oral care.

Here’s what the study reveals:

Garlic’s antimicrobial punch

Allicin, the active compound in garlic, is a powerful antibacterial and antifungal agent. Studies show it effectively reduces bacterial counts in the mouth, rivalling synthetic agents. “It’s remarkable that a simple plant can produce results comparable to established chemicals,” the authors say.

Side-effects worth noting

Burning sensations and odours are the main drawbacks, but they tend to be milder than chemical alternatives. Patients may need to weigh comfort against the benefits of a natural antimicrobial.

Easy access and affordability

Unlike chlorhexidine, which may require a dentist’s prescription, garlic-based mouthwashes are widely available over-the-counter. This accessibility could make herbal oral care a more practical choice for everyday hygiene.

A natural alternative

Garlic has been valued globally for its medicinal properties for centuries. Apart from its culinary uses, it continues to show potential in oral care, denture hygiene, and even as an adjunct for treating gum diseases.
