Some foods whisper their presence on your plate. Horseradish does the exact opposite. It enters with a sharp, fiery punch that clears your sinuses, makes your eyes water, and leaves a lingering heat on your tongue. But behind its intense flavor lies a surprisingly rich nutritional profile and a long history of medicinal use.
Often mistaken for just a spicy condiment served with roast beef or seafood, horseradish is actually a powerful root vegetable belonging to the same family as mustard, cabbage, and wasabi. It has been used for centuries in traditional medicine for respiratory problems, infections, digestion, and inflammation. In this guide, we’ll explore everything you need to know about horseradish — what it is, its nutrition, science-backed benefits, side effects, cooking methods, who should and shouldn’t eat it, and much more.
What is Horseradish?
Horseradish (Armoracia rusticana) is a perennial root vegetable native to Eastern Europe and parts of Western Asia. It belongs to the Brassicaceae family, which also includes broccoli, kale, cabbage, mustard, and radishes.
The plant grows long, thick white roots that look somewhat similar to parsnips. On its own, the root doesn’t have a strong smell. However, when it’s cut, grated, or crushed, enzymes called myrosinase are released. These enzymes convert compounds in the root (glucosinolates) into isothiocyanates, which are responsible for horseradish’s strong aroma and spicy taste.
Its flavor is sharp, peppery, and sinus-clearing, unlike the burning heat of chilies. The intensity kicks in quickly and disappears fairly fast. Horseradish is used in:
- Sauces and condiments
- Pickles and relishes
- Traditional medicinal remedies
- Skincare and hair treatments
- Natural antimicrobial preparations

10 Side Effects of Horseradish
