evidence: The following are some of my favorite herbal remedies for some of the biggest germ baddies out there. They are all recipes from world-renowned modern herbalist, Rosemary Gladstar. [...] ● 1 medium onion, chopped ● 4-5 cloves garlic, coarsely chopped ● 3-4 tablespoons freshly grated ginger root ● 3-4 tablespoons freshly grated horseradish root ● Apple cider vinegar (preferably unpasteurized) [...] Directions: Combine the onion, garlic, ginger, and horseradish in a widemouthed glass quart jar and add enough warmed apple cider vinegar to cover them. Warming the vinegar allows it to more actively draw the properties out of the herbs. Place in a warm spot (near a sunny window works) and let sit for 3 to 4 weeks. Strain, then discard the spent herbs. Add honey and cayenne to taste. The finished product should taste lively, hot, pungent, and sweet.
