Neilmed Sinus Rinses squirt saline into the maxillary and ethmoid sinuses. It does not work for
infections in the upper sinuses, says so right on
the box. It only costs $13 at any local pharmacy.
There is also a neti pot, which was demonstrated by Dr. Oz on the Oprah Winfrey Show. Many people swear by a neti pot, so it is apparently effective for some colds and some sinus infections. However, a neti pot flush may or may not reach the upper part of the sinuses.
