The remedy for a sinus infection that is one like to use is actually known as Neti, a process of nasal irrigation. Some people use water that is coupled their hands, but there are commercial Neti pots available on the market that help with the process. You take a mixture of tepid water and sea salt and allow it to go in one nostril and drain out the other. This helps to clear any foreign material out of the nasal passages, which actually extend far up into the forehead. By doing nasal irrigation on a regular basis you help to not only clear out any existing problems, but you help ward off any future problems that may occur as a result of not keeping your nasal passages clean.
