Yellow dock’s long, thin leaves are curled at the edges, which earns it the nickname curly dock. Known for its thick, yellow, fleshy roots, Rumex crispus has been employed in traditional herbal practices for its wellness-supporting qualities. Yellow dock root can be made into a syrup, decocted as tea, extracted, and infused in oil for topical application.
Curled dock bears multiple clusters of three-winged flowers. Its seeds are green in the summer but they become deep red as they mature. The root of yellow dock is bright yellow below the bark. The root is harvested in late summer after the seeds have begun to turn red.
