Young leaves, with a hairy texture and slimy when raw, are packed with minerals and can be eaten both cooked and raw. Although they are not pleasant to eat, they can be added to salads if finely chopped to avoid the hairs. The young shoots can be used as a substitute for asparagus. Older leaves can be dried and used as tea. The roots can be peeled, cut, and added to soups. They are also suitable for making tea. Finally, the roots can be roasted and used along with dandelions and chicory roots to make coffee.
