ENT spray is designed to get at those hard to reach places such as the ears nose and throat. Common complains such as, coughs, colds and ear infections may be caused by bacteria or viruses. In the case of ear infections fungus is often to blame. HealthWest ENT delivers a spray of positively charged silver ions, oxygen and distilled water. Note ENT contains only pure water, oxygen, and charged silver ions and does not contain any nanoparticles (metal colloids), fillers, stabilisers or chemicals of any sort. Most disease-causing microorganisms are very sensitive to oxygen and cannot survive in its presence. Positively charged silver ions work by disrupting the ability of the microbe to conduct electricity and communicate with itself.
