I have recently been having a lot of problems with a plugged ear. My work insurance has changed and it doesn't cover office visits, so I didn't want to pay $200 to my doctor, get referred to an ear specialist who would charge another $300 and then pay $100 for ear drops that would be just like $10 over the counter ear drops so I tried to fix it on my own. Ear drops didn't work and this went on and on until I got creative and filled my ear with coconut butter I got from Trader Joes. The next day, after 3 weeks, my ear was unplugged and it is still good weeks later. I can only guess that because coconut oil, which the butter is made from, is a natural antiseptic and killed any bacteria and promoted healing in my ear. Just a guess - but it worked great when ear drops did nothing so I just wanted to pass it on.
