Yellow Dock is a tall plant that turns rust-colored when it goes to seed. At the farm, it has been growing wild in the big field among the rye. As it changes color and goes to seed, it is ready to be harvested for its root, which is the part of the plant that is used in herbal remedies.
Yellow Dock has been found to have a cleansing, purifying effect on the body and is a natural source of iron. It can also provide relief after getting stung by stinging nettle--all you do is crush the yellow dock leaf and wrap it around the affected area.
