This is a practical guide explaining the treatment for chronic upper pharyngitis. The upper pharynx acts as a filter for viruses and other particles when you breathe through your nose. I am also currently doing nasal irrigation. If you are not feeling well, following the instructions in this book and performing nasal irrigation may improve your condition. Please read this book and give it a try. I've only read it two or three times, so it's almost like new. Please consider purchasing it. Please understand that this is a used item. - Title: Cure Chronic Upper Pharyngitis - Author: Osamu Hotta - Health, Medicine - Price: 1200 yen - Chapter Title: Chapter 4: Chronic Upper Pharyngitis is the "Root of All Diseases" Thank you for viewing.
