Onion has traditionally been used as a home remedy for ear infections and earaches in various cultures, especially in folk medicine. The most common method involves warming a piece of onion, wrapping it in a cloth, and placing it over or near the affected ear, or sometimes using onion juice as ear drops. The practice is based on the belief that onion’s natural antimicrobial and anti-inflammatory properties (due to compounds like allicin and quercetin) may help alleviate pain and reduce infection.

However, scientific evidence supporting the use of onion for ear infections or earache is minimal. There are no high-quality clinical trials or substantial biomedical studies that directly confirm its efficacy or safety for this purpose. Most available information comes from anecdotal reports and traditional knowledge passed down through generations. Additionally, medical professionals generally caution against putting any unsterilized substance, including onion juice, into the ear canal due to the risk of irritation, allergic reactions, or worsening infection—especially if the eardrum is perforated.

Overall, while the use of onion for earache is deeply rooted in tradition, scientific validation is lacking. Its use should not replace evidence-based medical treatments, and it is best to consult a healthcare provider for ear pain or suspected ear infection.
