Horseradish Isn't Just Spicy—It May Fight Inflammation and Cancer Too

Horseradish, the pungent root from the Armoracia rusticana plant, has long been known for its sharp flavour. Now, research suggests it may also offer a range of health benefits—from fighting inflammation to potentially combating cancer. Belonging to the mustard family, this root packs more than just a spicy kick. The root’s strong taste comes from oils that can irritate sinuses and bring tears to the eyes. But these same compounds may help clear congestion by boosting mucus production and flushing out microbes. Studies indicate that horseradish can ease sinus and lung blockages, making it a natural decongestant.

At the heart of its health benefits are isothiocyanates, chemicals with powerful antibacterial effects. These compounds fight bacteria like *E. coli* and *H. pylori*, and they may even stop the growth of fungi responsible for skin and nail infections. Early lab research also shows that isothiocyanates have anti-tumour properties, suggesting potential anticancer effects. Horseradish contains sinigrin, a substance that interferes with inflammation—a key factor in diseases such as Alzheimer’s, arthritis, cancer, diabetes, and heart disease. By disrupting this process, it may help reduce the risk of atherosclerosis. Despite its potency, the root is low in calories, with one tablespoon offering just 7 calories, 2 grams of carbs, and a small amount of vitamin C. For most people, eating horseradish daily poses no issues, provided it doesn’t cause irritation. However, those with inflammatory digestive conditions might find it worsens symptoms.

With its mix of antibacterial, anti-inflammatory, and potential anticancer properties, horseradish offers more than just a fiery flavour. A small daily amount could support health, though moderation is key for those with sensitive digestive systems. Its low-calorie content and nutrient profile make it an easy addition to meals for those looking to boost their diet.
