Also known as earthsmoke or Indian fumitory. Constituents include isoquinoline alkaloids and hydroxycinnamic acid derivatives. It is spasmolytic to the bile duct and gastrointestinal tract, and at least some of these actions are due to the presence of sanguinarine, which is antiseptic.

It also has anti-pain and anti-inflammatory properties. The Fumariline in this herb is analgesic. 

Found in Potter’s Elixir of Echinacea Plus.
