Yeast Arrest has boric acid plus other unique herbal homeopathic ingredients in a cocoa butter base, including natural ingredients and lactobacillus acidophilus, which are helpful to fight against yeast infections and bacterial vaginosis (BV). Boric acid is a safe substance with mild antiseptic properties. In one study of 100 women with chronic yeast vaginitis that had failed to respond to treatment with over-the-counter or prescription antifungal medicines, 98% of the women successfully treated their infections with boric acid capsules inserted into the vagina twice per day for two to four weeks. Several commercial douching products contain boric acid. If pregnant, consult with your OB/GYN or health care practitioner before use.
