*Blood Pressure : Acetic acid may help lower blood pressure, according to an animal-based study published in Bioscience, Biotechnology, and Biochemistry in 2001. Again, it's unknown whether this study tested the use of acetic acid derived from apple cider vinegar or from another vinegar type.
*Cholesterol : Published in the British Journal of Nutrition, a 2006 study found that rats fed acetic acid for 19 days had a significant reduction in total cholesterol and triglyceride levels. In an animal-based study published in the Pakistan Journal of Biological Sciences, scientists found that diabetic rats fed an apple-cider-vinegar-enhanced diet for four weeks experienced an increase in HDL ("good") cholesterol (as well as a reduction in their levels of triglycerides, a type of harmful blood fat).
*Cancer. A few laboratory studies have found that vinegar may be able to kill cancer cells or slow their growth. One study found that eating vinegar was associated with a decreased risk of esophageal cancer. Another associated it with an increased risk of bladder cancer. In recent trials, pectin, which can be found in ACV, has shown promise in helping to slow the growth of cancerous cells within the prostate (http://www.news-medical.net/news/20100702/Modified-Citrus-Pectin-holds-promise-against-prostate-cancer.aspx). In addition, apple cider vinegar’s acidity aids in detoxifying and cleansing the digestive tract and cleaning out the colon, which supports the health of the prostate as well.
*Dandruff : A home remedy for dandruff is to mix 1/4 cup apple cider vinegar with 1/4 cup water. The vinegar solution is thought to restore the restore the pH balance of the scalp and discourage the overgrowth of malassezia furfur, the yeast-like fungus thought to trigger dandruff.The vinegar mixture is usually poured into a spray bottle and spritzed on the hair and scalp, avoiding the eye and ear area. A towel is then wrapped around the head and left on 15 minutes to an hour. After that, the vinegar can be washed from the hair. Alternative practitioners often recommend it once or twice a week for dandruff.
*Acne : When using apple cider vinegar to treat acne, some alternative practitioners recommend mixing one part apple cider vinegar with three parts water. The solution is then dabbed onto the pimple. Since there have been case reports of skin damage and burns from using full-strength vinegar on the face, it's important to take caution when using this remedy.
