A few years ago, I had sinusitis. I went to a number of doctors, including an otorhynolaryngologist. Nothing worked and was advised to have surgery. A stranger suggested I use garlic powder to treat sinusitis. I was instructed to basically snort tiny mounds of the powder and to be sure to use water. I tried for a while and in a few days was relieved. Now that I think about it, is this a safe way to treat the infection? Is it really treating it, or doing something else?
