I would like readers to try this. Add two tablespoons of ACV to lukewarm water and gargle all the way from your deep throat. Check the contents of your ACV water BEFORE and AFTER. All the more, if you are a vivid caffeine fan. You would notice all the gunk come out in lumps. Then you can imagine what it can do to your entire system. However ACV is not for everyone. Gargling, anyone can do, but if your stomach is of acidic nature, please be cautious using ACV INTERNALLY.
