Cloves, the dried flower buds of the Syzygium aromaticum tree, are native to Indonesia but now grown in tropical regions worldwide. Harvested by hand before blooming and sun-dried until reddish-brown, they are valued for their flavor and medicinal qualities.

The key compound in cloves, eugenol, has strong antibacterial and anti-inflammatory properties. “Traditionally, cloves have been recognized for their ability to decrease tooth pain and prevent gum disease.” Clove oil or clove-based mouthwashes can reduce harmful mouth bacteria, fight plaque, and ease gum inflammation—but should be used in moderation and never swallowed. Persistent oral problems still require a dentist’s care.

Cloves may also help manage blood sugar. Research suggests eugenol could improve insulin sensitivity, potentially lowering blood sugar levels. However, “cloves cannot replace traditional blood sugar medications,” and anyone on such medication should consult a doctor before high-dose use.

For most people, the safest way to enjoy cloves’ benefits is by adding them naturally to food and drinks. This not only enhances flavor but also supports oral health and may aid blood sugar control without disrupting medical treatments.

A small spice with a big impact, cloves offer warmth in cooking and potential boosts for health when used wisely.
