Physical Characteristics of Wild Horseradish
Wild Horseradish looks most similar to dock and the easiest time of the year to identify between the two is in autumn when the dock leaves start to look rough and get red damage marks on the leaves. Horseradish leaves will stay vibrant and lush green. I always think if you see something that looks like an incredibly healthy dock leaf in autumn you’ve most likely got yourself some horseradish.
Root –
A large, white, tapered root, the root when intact doesn’t really smell but once grated, chopped or damaged it will release the familiar aroma. The root can become quite gnarled and be difficult to remove depending on ground conditions and permission must be gained from the land owner.
Leaves –
Hairless, bright green, unlobed leaves that can grow upto 1 metre long and resemble dock leaves. When crushed they give off the horseradish scent.
Flowers –
The white four-petalled flowers are scented and grow in dense panicles. The flowers as with many members of the Brassicaceae family form a cross.
Edible Uses of wild horseradish
The leaves and the roots are both edible.
The young leaves can be eaten raw or cooked like spinach or cabbage.
The root is really the best part of this plant. It is best to harvest it in early winter. It is much stronger in flavour than the cultivated variety and is traditionally used to make horseradish sauce.
It also has many uses in herbalism including to treat skin redness, digestive disorders, constipation, chest infections, arthritis, chilblains, muscle soreness, and urinary tract infections.
It has also been used as a diuretic, antiseptic and expectorant. Research is being undertaken into potential anti-tumour properties.
