The seed was commonly used as an external wash by the Greeks, Romans and on through the Middle Ages for various skin parasites.

Today, it is considered toxic for ingestion. The plants have finely lobed leaves and bloom with pretty spikes of purple. Prefers a partly sunny location and plenty of moisture.
