For external use you can gently rub a little coconut oil with your hand onto the site of the infection three to four times a day in order to get the best results. Using this type of oil will help to calm down the burning and itching sensation that a yeast infection can cause. If you are suffering from a vaginal yeast infection soak a tampon in coconut oil and wear the tampon for a few hours. The affect that coconut oil has on your yeast infection will not happen over night but will happen gradually. Before you see any signs of improvement you need to use the coconut oil for at least seven days. Coconut oil can also be used for localized treatment of jock itch and yeast infections.
