#7 Vinegar
Vinegar is yet another kitchen staple with multiple uses. While it may burn a bit, using it on a cut or other injury will keep infection away. It can also be used to masks odors – both those you do not want to smell and those you don’t want other people to smell.
Additionally, it can be used to kill parasites in meat – either by marinating the meat prior to cooking or ingesting after eating the meat.
