I understand that vinegar is made from fermented wine, beer or ale and its most commonly used as a condiment but can be used as a preservative too. With regards to the Naturopaths, they are doctors just like MD's but their approach is more holistic i.e. what' going on in a person's entire body and life affects their health. They believe the body possesses the ability to heal just as effectively with herbs, vitamins, foods etc, as with traditional medicine. I use both western medical docs and naturopaths because I think they compliment each other nicely.
