What is Rootology and how does it work? Nasal & sinus health can quickly deteriorate and make our lives miserable, whether due to pollen, dust, mold, chemicals, wildfire smoke or whatever's in the air that may congest or trigger a sneeze. Rootology is a blend of 13 concentrated herbal extracts to support against sneezing, congestion, sinus pressure, runny nose, itchy watery eyes, and headache.* I have been practicing Allergy and Clinical Immunology for over 25 years and I am really excited to recommend Rootology, a new all-natural product that really works. Rootology is first line in my practice!"
