Horseradish (Armoracia rusticana) has a long history of traditional use in Europe for supporting urinary tract health, including the treatment of bladder infections (cystitis). The root contains glucosinolates, particularly sinigrin, which upon hydrolysis release allyl isothiocyanate—a compound thought to have antimicrobial properties. In traditional herbal medicine, horseradish has been used as a diuretic and antimicrobial remedy, often prescribed for urinary tract infections (UTIs) alongside other herbs like nasturtium. While some in vitro studies demonstrate that horseradish extracts can inhibit the growth of certain bacteria, including Escherichia coli (a common cause of UTIs), the clinical evidence in humans remains limited. A few small clinical trials and combination herbal products (e.g., horseradish and nasturtium) have shown potential efficacy in reducing the recurrence of UTIs, but these studies are not conclusive and often lack rigorous controls or adequate sample sizes. Most major clinical guidelines do not recommend horseradish as a first-line or sole treatment for bladder infections due to insufficient evidence. In summary, horseradish’s use in bladder infections is primarily based on traditional herbal practice, with some preliminary but limited scientific support.
