From the existing encyclopedia
Foxglove is a tall biennial with tubular purple flowers containing cardiac glycosides such as digoxin. It is a historical source of heart medicines discovered through toxicology, not kitchen use. Never consume foxglove leaves, flowers, or seeds; misidentification has caused fatal poisonings. This page is botanical education only. Do not forage or sell foxglove for ingestion.
