Four Thieves Vinegar
Legend has it that during the Great Plague of the Middle Ages, grave robbers would wash their hands in a solution called “Four Thieves Vinegar,” which was very effective in staving off infection. The concoction was made by infusing vinegar with wormwood, rue, mint, sage, lavender, and rosemary. Because these constituents all have known antibacterial and antiviral properties, it seems like a feasible tale.
The finished product can be used externally, and safely, for a variety of purposes: as a surface disinfectant, a hair rinse, a skin cleanser, to treat insect bites, as a hand-sanitizer, just to name a few. While the ingredients are very effective, it is gentle enough to use on pets and kids, just dilute it one part Four Thieves to three parts purified water.
