Burdock is a plant that is found all over the world. Burdock root is sometimes used as food. The root, leaf, and seed are used as medicine.

Burdock is used for skin problems, stomach problems, joint swelling, and other conditions, but there is no good evidence to support its use for any condition.

Burdock has been associated with poisonings because some products have been contaminated with root of belladonna. These poisonings do not appear to have been caused by burdock itself.
