Clove bud oil, also known as eugenol, has many potential medicinal uses, including:

• Pain relief: Clove oil contains eugenol, a natural anesthetic that can help with toothaches, gum discomfort, and pain from dental work.
• Antibacterial and antifungal properties: Clove oil can help fight infections and has been shown to kill staph bacteria in liquid culture and biofilm.
• Anti-inflammatory: Clove oil contains anti-inflammatory chemicals that can help reduce inflammation.
• Blood pressure: Clove oil may help lower blood pressure by dilating mesenteric arteries.
• Skin health: Clove oil can help with dry skin and soothe skin irritation.
• Congestion: Inhaling a combination of clove bud oil and myrtle essential oil can help open airways and manage congestion.
• Tooth enamel: The eugenol in clove oil may help reverse or lessen the effects of high-acid foods and drinks on tooth enamel.

Clove bud oil is also used as a flavoring in foods and teas. 

While clove oil has many potential uses, there isn’t enough scientific evidence to support all of them. High doses of clove oil can cause severe liver injury.
