A sinus irrigation technique using a diluted solution of fermented apple juice introduces acetic acid and other compounds into the nasal passages. This method aims to cleanse the nasal cavity, potentially alleviating congestion and removing irritants. Solutions often consist of a mixture of purified water, apple cider vinegar, and sometimes salt, administered through a neti pot or squeeze bottle.
Proponents of this practice suggest it may provide relief from seasonal allergies, sinus infections, and nasal dryness. The purported benefits stem from the acetic acid’s potential antimicrobial properties and its ability to break down mucus. Historically, sinus irrigation has roots in Ayurvedic medicine, with apple cider vinegar emerging as a more recent addition to traditional saline solutions due to its perceived health advantages.
