4. Apple cider vinegar
ACV has become a homeopathic cure-all, and for good reason, as it contains powerful components that can cure infections. You can use apple cider vinegar to treat a sinus infection two ways. One option is to mix a teaspoonful with a glass of cold water and drink it down. Another option is to mix a few drops into lukewarm purified water and use it as a wash for your sinuses. You can use a Neti pot, a simple apparatus that is specifically designed to flush the nasal passages and the accompanying sinuses. Make sure to use apple cider vinegar in the raw, as the mother contains enzymes that are helpful for fighting inections.
