Vinegar has been used for many years to help a number of conditions from scurvy and cholera to asthma or bad breath, explains HowStuffWorks. Modern science, however, does not support most of the known uses for vinegar in medicinal ways.
Many people use vinegar for pain relief including pain in the back, for headaches and leg cramps, explains HowStuffWorks. Sitting in a bathtub filled with water and two cups of vinegar for 30 minutes may help to relieve back pain, for instance. People often try to relieve headaches by using a 1-to-1 vinegar and warm water solution on a washcloth that is placed on the forehead. For leg cramps, full strength vinegar placed on a rag, then on the skin, may help them go away.
Vinegar is also used as a cure for respiratory conditions, claims HowStuffWorks. Sprinkling a pillowcase with vinegar, for instance, is a home remedy for night time coughing. Head or chest congestion may be cured by filling a humidifier with 1/4 cup of vinegar and running it for an hour. Vinegar may also help to ease the pain of a sore throat as it is often used as a gargling agent when added to a cup of water. Diluted vinegar in a spray bottle is also used on the skin when sunburn occurs.
