The use of vinegar with a variety of plants or essential oils for cosmetic purposes can be traced back to the Romans and was fashionable during the nineteenth century as vinegar de toilette.

Vinegar has a tonic action that promotes blood circulation in the small capillaries that irrigate the skin. It is also antiseptic, preventing the proliferation of bacteria, viruses, or yeast that trigger infection. It can dissolve excessive fatty deposits at the surface of the skin and reduce scaly or peeling conditions. Lastly, vinegar regulates the pH of the skin. Vinegar is most effective when used with lavender, rosemary, rose, or elder flower. It is essential to use top-quality white wine or cider vinegar. Dry any fresh plant material for two days before using.

Measure and mix only dried plant material and then add the vinegar. Apple ciders composed entirely of liquids can be used at once. Those containing plant material must be left to macerate. Prepare the latter in a screwtop jar and leave on a window sill as instructed, strain, and then bottle. To use, add 1 teaspoon of apple cider to a cup of bottled or spring water to wash your face or pour 3-4 tablespoons into a bath.
