Onion (Folk Remedy) for Ear Health

Research on onion as a folk remedy for ear health is essentially absent from the published literature, and the single available study does not address ear health specifically. The one linked study is a cross-sectional survey of primary care patients in Switzerland and France examining home remedies for upper respiratory symptoms such as sore throat and cough, with no mention of ear-related conditions or onion as a studied remedy. Studies indicate that while folk remedies enjoy widespread use and perceived effectiveness among patients, this survey-based evidence reflects self-reported perception rather than clinical outcomes, and its scope does not extend to ear health applications. Anyone seeking information on remedies for ear conditions should be aware that no research evidence was identified to support or refute the use of onion for this purpose.
