My son has a chronic runny nose as well, however if he avoids dairy it clears up. He cuts back on processed carbs as well and it helps. He was cutting weight for wrestling when we noticed the improvement:)
Ingredients to Avoid
I had a bad case around my nose but did not want antibiotics again. I switched to a SLS-free toothpaste. I also did an internal cleanse (Cleansesmart)and added a probiotic (Jarro-Dophilus). Within 4 days it is gone!
