The act of rinsing the throat with a diluted solution of fermented apple juice is a practice employed by some for various perceived health benefits. The solution typically involves mixing the vinegar with water to mitigate its acidity. This diluted mixture is then agitated in the back of the throat, held for a short period, and expelled.
Historically, vinegars have been utilized for medicinal purposes, dating back to ancient civilizations. Proponents suggest that this specific type of vinegar rinse can help alleviate sore throats due to its potential antibacterial properties and ability to break down mucus. It has also been suggested as a breath freshener and even as a tooth-whitening agent, although evidence supporting the latter claims is limited and potentially harmful.
