On occasion, yoga does require fasting which cleanses the body of toxin and may work on a yeast infection by cleaning out the build up of sugars and refined carbohydrates. Your mental and physical relaxation also contributes to the healing process as a body and mind that is stressed can result in lowered immunity. This can contribute to the overgrowth of Candida, a yeast infection. Yoga for yeast infection will not work alone but is a good all around line of attack to a cure as is keeping cool and dry to avoid a breeding ground for Candida. Yoga definitely has its place in increasing ones health thereby decreasing the possibility of needing to find a cure for a yeast infection.
