4 Thieves Vinegar
Get a jar or bottle about twice the size of how much you want to make. (I prefer jars with wide mouths).
Put in it a bunch of cloves of fresh garlic and then put in a tablespoon or two of these herbs: lavender, peppermint, rosemary, sage, cloves, wormwood/mugwort.
You can then add a teaspoon or two of any of these you have around: Rue, marjoram, Peppercorns, anise hyssop, meadowsweet, angelica, horehound, camphor, lemon balm, ginger, yarrow, oregano, cayenne peppers, calendula, licorice, coriander, tansy.
Cover the herbs with vinegar. I prefer apple cider vinegar, others use wine vinegar. Let it sit for a couple weeks at least- if you are in a hurry, shake it every so often, and make sure the herbs stay under the vinegar. When it’s sat as long as you want, strain it and put it into a pretty bottle (or whatever you like).
This can be for a wash, can be taken orally (can be put on salad). It keeps away bad influences (and let’s face it, it’s a garlic infusion, and garlic is antibiotic, antiviral, antiparacitic, it’s just amazing stuff).
The thing is that while the first set of herbs (and garlic) are in just about every 4 Thieves Vinegar recipe, the rest occur occasionally in other recipes I’ve seen over the years. My impression is that everyone wants to put in their personal favorite herbs. Be a bit careful about ingesting much, if you use add much rue or other pesticide herbs (although they do keep other things away).
