The key in using apple cider vinegar to treat kidney stones is consistency. You should take apple cider vinegar every day with lots of water until the stone is completely dissolved, or the pain from the kidney stone (and accompanying issues while urinating) goes away completely.
Apple cider vinegar can also be taken for urinary bladder infection in order to prevent the infection from spreading into the kidneys. It also helps in resolving bladder infection and in promoting a speedy recovery. Apple cider vinegar has a pH level of 3.0.
