This is a MILD version of original Sinus Plumber natural nasal spray. This formula contains 75% less pepper than original Sinus Plumber and it does not contain horseradish or wintergreen. It works like the original formula for moderate symptoms, but it's designed to be used as a daily powerful nasal cleanser and preventative. There is still a small pepper sensation, but nothing like original Sinus Plumber capsaicin nasal spray. It's mild yet still powerful enough to help with general allergy and sinus symptoms and also for cleansing the nose from airborne particles. Use daily for healthy clear sinuses and to ward off particles that can cause colds and flu. Use only as directed. This product is not intended to diagnose, treat or cure any disease or medical condition.
