Common Fumitory
Found on banks and roadsides, and especially around the edges of fields.
The Manx name for fumitory is "booa ghone", which means "brown cow".
Fumitories were once used in herbal medicine as a remedy for skin diseases and conjunctivitis.
Fumitories are a source of "fumaric acid", which is a common food additive. Fumaric acid is currently being investigated as a potential treatment for multiple sclerosis.
