4. Tea Tree Oil
Tea tree oil, also called melaleuca, is another oil that has powerful antiseptic properties and which can work to kill off the infection while also breaking up the mucus. It will also help to mix this with a little coconut oil for the right consistency.
Note however that these are tips that have anecdotal evidence but not scientific evidence. It is also unknown whether applying antibacterial/antiviral agents topically will have the desired effect as the bacteria does not live in the ear but rather in the body.
