Horseradish (Armoracia rusticana, syn. Cochlearia armoracia) is a perennial plant of the Brassicaceae family (which also includes mustard, wasabi, broccoli, and cabbage). It is a root vegetable used in food as a spice and also has medicinal uses.
The plant is probably native to southeastern Europe and western Asia. It is now popular around the world. It grows up to 60cm – 1 meters (2-3 feet) tall, and is cultivated primarily for its large, white, tapered root.
Cultivation: Immediately replant seedling plant into well drained soil, in an open sunny position. Water only when soil is dry. Do not not grow indoors.
Culinary uses: Make horseradish sauce to accompany roast beef, smoked or oily fish. Grate root into coleslaw, dips, pickled beetroot, cream cheese, mayonnaise and avocado fillings.
Medicinal uses: used for urinary tract infections, kidney stones, fluid retention, cough, bronchitis, achy joints (rheumatism), gallbladder disorders, sciatic nerve pain, gout, colic, and intestinal worms in children. Include grated root in diet.
