Goldenseal, oat straw, and cat's claw are natural herbs often used to support the body's defense against yeast infections. Goldenseal contains berberine, which may help inhibit yeast overgrowth, while cat's claw is known for its immune-enhancing and anti-inflammatory properties that can support the body in fighting infections. Oat straw provides nourishing minerals that help maintain skin and mucosal health, potentially easing discomfort and irritation associated with yeast infections.
