Horseradish: The Spicy Root with Surprising Health Perks and Risks

Horseradish, derived from the root of the Armoracia rusticana plant, is a pungent condiment with a long history of culinary and medicinal use. It is often grated or pureed with vinegar to create a sharp, creamy sauce. The root contains powerful compounds like isothiocyanates. These give horseradish its strong flavour and antibacterial properties. Studies show they can destroy harmful bacteria such as E. coli and Salmonella, as well as fungi causing skin and nail infections.

Horseradish also contains sinigrin, a chemical that helps reduce inflammation. This may benefit conditions like atherosclerosis. Additionally, an herbal preparation with horseradish proved as effective as antibiotics in treating sinusitis and bronchitis.

Nutritionally, one tablespoon of prepared horseradish provides about 7 calories. It includes small amounts of carbohydrates, fibre, and minimal fat or protein. However, its oils can irritate the sinuses and cause watery eyes. While horseradish can be consumed daily, it should be avoided if it causes irritation or by those with inflammatory digestive issues. Its potential health benefits, including anti-inflammatory and antimicrobial effects, make it a notable plant in both medicine and cooking.
