In a ½ gallon glass jar, or 2 quart jars, layer horseradish, ginger, onion, garlic, orange, lemon, peppers, and elderberries.
Top with calendula flowers.
Slowly pour raw apple cider vinegar over the ingredients. Be sure that all the ingredients are submerged.
Add a plastic lid, or place a piece of parchment paper on the jar before adding a metal lid (the ACV will corrode the metal lid).
Place in a dark cool cupboard for 4 - 6 weeks, shaking every few days. Add more apple cider vinegar if any of the ingredients are not covered.
After 4 - 6 weeks, line a colander with muslin and strain, allowing to drain for 30 minutes.
Add raw honey to taste and store in a clean jar. I keep mine in the refrigerator but it can be kept in a cool dark place for a year.
To use, take 1 - 2 tablespoons at the first sign of a cold, and repeat every 3 - 4 hours.
