Unsweetened cranberry juice may acidify vaginal secretions and equip them to fight off the yeast. Eating two fresh garlic cloves a day, either plain or minced and tossed in a salad or sauce, may also prevent yeast infections or help clear up a case of thrush. Garlic has antifungal properties.
For thrush, brush your teeth after every meal with a mild toothpaste of baking soda and water. Commercial toothpaste may be too harsh if sores develop. Pour a little baking soda in your hand and add just enough water to make a paste. Then, rinse with 1/2 cup warm water and 1 tablespoon of three percent hydrogen peroxide. Replace your toothbrush when the infection is cured.
