Overview

Yellow dock (Rumex crispus) is a common weed found in Serbia, Korea, and China. The leaf stalks are used in salads. The root and fruits are used as medicine.

Yellow dock contains chemicals that work as laxatives and have anti-inflammatory effects. It also contains chemicals that might kill parasites, bacteria, and fungi.

People use yellow dock for pain, swelling of the nasal passages and the respiratory tract, constipation, hemorrhoids, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse yellow dock with sorrel or wood sorrel. These are not the same.
