Apple cider vinegar (ACV) is prepared by pulverizing apples into a slurry of juice and pulp and then adding yeast and sugars.
Reports of the healing properties of apple cider vinegar date to 3300 BC. In 400 BC, Hippocrates supposedly used apple cider vinegar as a healing elixir, an antibiotic, and for general health. Samurai warriors purportedly used a vinegar tonic for strength and power. U.S. Civil War soldiers used a vinegar solution to prevent gastric upset and as a treatment for pneumonia and scurvy.
Apple cider vinegar has been used alone and in combination with other agents for many health conditions. Anecdotally, ancient Egyptians used apple cider vinegar for weight loss. During the diet "craze" of the 1970s, proponents suggested that a combination of apple cider, kelp, vitamin B6, and lecithin could "trick" the body's metabolism into burning fat faster. Claims of preventing viral and bacterial infections, as well as allergic reactions to pollen, dander, and dust, stem from the proposed ability of apple cider vinegar to prevent alkalinization of the body. However, there is not enough scientific evidence to form a clear conclusion about the efficacy or safety of apple cider vinegar for any health condition.
No specific doses are supported by well-designed clinical trials. In general, 2 teaspoons of cider vinegar have been taken in 1 cup water three times daily. Also, 285-milligram tablets have been taken with meals. Topical and rectal preparations have also been used but safety is unclear.
