Yes, a baking soda bath can help with yeast infections. The alkaline nature of baking soda helps to create an environment inhospitable for the growth of yeast, thus helping to reduce symptoms such as itching and burning. Additionally, the natural anti-fungal properties of baking soda make it effective at killing off overgrowth of Candida albicans, one of the main causes behind yeast infections. To use this remedy, simply fill a tub with warm water and add 1/2 cup baking soda then soak in the bath for 15 minutes or more. This simple yet effective treatment should be done several times per week until desired relief is achieved.
