Oregano oil. Known for its antimicrobial properties, oil of wild oregano can help you fight a yeast infection. For oral consumption, mix about three drops of food-grade wild oregano oil into a glass of water and drink it. After doing this for a few days, increase this practice to once in the morning and once in the evening. Alternatively, you can swallow prefilled oregano capsules. Consider topical applications for a vaginal yeast infection. You can insert capsules into your vagina and leave them in place while you sleep. If you don’t have capsules, consider mixing wild oregano oil with a carrier oil. Apply this mixture to a tampon, which you can leave in your vagina for up to six hours at a time.
