FROM " science based medicine " WARNING ON " NAVAGE " nose cleaner

[Navage airs its TV commercials with annoying frequency. They say: Pandemics remind us that germs invade through your nose, the body’s natural air filter for trapping allergens, dirt, and viruses. But how do you clean it? It’s easy with Navage. Navage uses powered suction to flush out all the stuff that causes congestion, allergies, colds, and worse. When your nose is clean, so many good things happen: you breathe better, sleep deeper, snore less, and feel healthier. Join millions who use all-natural, drug-free Navage. You’ll love that clean nose feeling. This ad raises a lot of questions in my mind This is all marketing with no science. It seems to imply that Navage can prevent COVID-19, but there is no evidence that it does. The only evidence that “good things” happen is unreliable testimonial evidence from satisfied users. There have been no clinical studies to evaluate the company’s claims. Millions may use it, but the argument from popularity is a logical fallacy. It uses saline pods, but no drugs (unless you consider saline to be a drug). But is it all-natural? I don’t see how a battery-powered device with a motor could be considered “natural.” It may give you a “clean nose feeling,” but that doesn’t mean it is clinically effective.]
