Eugenol, a major component of clove oil, has a long history of use in traditional medicine for alleviating earache and supporting ear infections. Its use is primarily based on its known analgesic (pain-relieving), anti-inflammatory, and mild antiseptic properties, which have been recognized in folk remedies, particularly in South Asian and Middle Eastern cultures. Traditionally, a few drops of clove oil diluted in a carrier oil have been applied to a cotton ball and placed in the outer ear canal to reduce discomfort associated with earache.

However, scientific evidence supporting eugenol's efficacy for ear infections or earache is limited and largely indirect. Most studies focus on its effects on dental pain, oral bacteria, or as a general antimicrobial, rather than specifically targeting pathogens associated with otitis media or externa (common causes of ear infections). Laboratory studies confirm that eugenol has antimicrobial activity against a variety of bacteria and fungi, but clinical trials for ear-specific conditions are lacking. Furthermore, the direct application of essential oils to the ear canal carries risks, including irritation or allergic reactions, especially if the eardrum is perforated.

In summary, while eugenol's use for ear pain is rooted in tradition and supported by its general analgesic and antimicrobial properties, high-quality clinical evidence for its safety and efficacy in ear infections or earache is insufficient.
