this is so true, granddaddy has been telling me this for years. i started using it when i am sick. its amazing: 2 Tablespoons organic apple cider vinegar, a teaspoon of pure lemon juice, touch of honey (optional), 12 ounces of water. Drink everyday to clear acne, promote digestion, help sinus infections/sore throats, etc. - - I drink it like a hot tea.
