Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Boric acid is scientifically validated as a treatment for certain fungal infections, particularly recurrent vulvovaginal candidiasis (yeast infections) caused by non-albicans species of Candida that are resistant to standard antifungal therapies. Multiple clinical studies and reviews support its efficacy. For example, a review published in Obstetrics & Gynecology (2007) highlighted cure rates of 70–100% for intravaginal boric acid in women with chronic or recurrent yeast infections, especially those not responding to azole antifungals. The Centers for Disease Control and Prevention (CDC) guidelines recommend boric acid (600 mg intravaginally once daily for 14 days) as an alternative treatment for non-albicans Candida infections. Its mechanism of action is believed to involve disruption of fungal cell walls and interference with microbial enzyme systems, making it broadly antifungal and also somewhat antibacterial. However, boric acid is not recommended for use in pregnant women, and it must be used only as directed due to potential toxicity if ingested. Overall, while not the first-line therapy, boric acid is a scientifically supported, evidence-based option for specific, difficult-to-treat fungal infections. The evidence is robust for vaginal use, but data for other types of fungal infections (e.g., onychomycosis, athlete’s foot) are limited or anecdotal.
