@Home Remedy for Fever: VINEGAR SOCKS! When you have a baby or small child who has a very high fever and medication just won’t bring it down. Take a pair of white socks, soak them in apple cider vinegar or white vinegar. Put them on the childs feet and wrap the feet in a towel. Wait till socks have dried, if fever is still high, repeat. I’ve never had to do it twice, once has always done the trick. Trust me ladies this does work.
