Overview

Wormseed (Artemisia cina) is an herb. Traditionally, the flowers are used to make medicine, but it is considered toxic and unsafe.

Wormseed contains a chemical that might kill worms that live as parasites in the stomach and intestines.

People use wormseed for parasite infections, but there is no good scientific evidence to support any use. Using wormseed can also be unsafe.

Don't confuse wormseed with plants with similar common names, including Artemisia herba-alba, mugwort, sweet annie, wormwood, or levant berry. These are not the same.
