"In the early 90’s we listened to Bertha Reppert, founder of The Rosemary House talking about some simple home remedies, and within a few days, several of the actors at the Renaissance Festival where we had an herb shop showed up covered with poison ivy. Bertha had talked about steeping sage in apple cider vinegar, and we’d gone home and started a batch. It was very effective for the poor sweaty, suffering actors, and we were impressed. This couldn’t be simpler, and is just wonderful as is. Just fill a jar with sage from the garden (or grocery store) and cover with vinegar. If you’re in a hurry, heat the vinegar and steep the sage in it as you would an herbal tea.
The following year we added plantain and jewelweed to the original brew, to add even more healing properties to the vinegar. We’ve used it ever since.
I just made a quart up today.
