Horseradish is more than just an aromatic root vegetable. It has been used medicinally all over the world for centuries. Here’s what the experts have to say about the health benefits of horseradish:
Horseradish, like other members of the mustard plant family, contains a chemical compound called sinigrin. Sinigrin has been shown to help reduce inflammation by blocking or changing the parts of the immune system that cause inflammation. 
Horseradish root is naturally rich in antioxidants, which can help protect your body from cellular damage by attaching themselves to free radicals.
