There is no research that sensorineural hearing loss can be reversed or treated with essential oils. However, essential oils contain properties that can help the body fight what may be causing hearing loss. For example, eucalyptus, while loved by koalas, is also great for people with allergies, which could be contributing to some fluid behind the ears and even a muffled feeling. Lavendar can soothe and possibly help with the by products of hearing loss or tinnitus by reducing overall body inflammation.
