@joangma - I know that I prefer natural products to help heal or prevent problems in my body. Changing the ph of your body is not a light thing as a treatment for a hang nail. These are chemicals and it's best to check with your doctor before taking any chances. Using chemicals to change something in your body is like using a dull instrument. There can be serious side effects to consider. Have you checked with your doctor? Do you know if you have a high acidic PH?
