Destinol is a popular treatment for women that suffer from vaginal odor.  Normally the vaginal odor is caused by a condition called bacterial vaginosis whcih itself is sometimes referred to as vaginitis.  The exact cause of BV is not known, but it is thought that a lowering of the healthy bacteria in the vagina allows the unhealthy bacteria to increase and cause the unpleasant odor.  Factors that can increase the chances of suffering from BV include smoking, multiple sex partners, regular antibiotic use and vaginal douching. You can also take a probiotic that can help to balance the bacteria to healthy levels in the vagina, therefore decreasing the risk of the unhealthy bacteria taking over.
