Horseradish (Armoracia rusticana Brassicaceae)

Other Names: Common Horseradish, Peasant Horseradish

Horseradish, widely known as a pungent spice, has been used medicinally in Europe for centuries. This plant features large leaves and a thick root with brown skin and a white interior. Rich in vitamin C, it was historically carried by sailors to prevent scurvy during long voyages.

Parts for Use

Roots

1. Harvested in autumn, resembling a large parsnip.
2. Best used fresh and can be stored in the refrigerator for months.
3. Rarely used in tinctures but incorporated into some pharmaceutical products.

Ingredients

Horseradish contains an essential oil rich in sulfur compounds called glucosinolates, unique to the cruciferous family, which can irritate the skin and cause blisters or burns. It has twice the vitamin C content of lemons and includes B vitamins and minerals such as potassium, calcium, iron, and phosphorus.

Use in Treatment

Horseradish stimulates digestive juice secretion, aiding the digestion of fatty fish and meats. Its strong diuretic properties make it a traditional remedy for kidney stones and urinary retention, and it is used for urinary tract infections and fluid retention. The plant’s ability to increase sweating helps with mild fevers. Its high vitamin C content, antibacterial action, and expectorant properties make it effective for cough and bronchitis. Applied externally, horseradish temporarily warms the skin, providing relief for painful conditions like arthritis and gout.

Cultivation

Horseradish is easily grown from root cuttings in well-drained, rich soil in sunny or semi-shady locations. It can spread aggressively, so careful management is needed.
