Blue Flag in Newfoundland
Information taken from “Micmac Medicines” Remedies & Recollections by Laurie Lacey, Page (23)
This plant may have had several uses. However, it must not be confused with the sweet flag, which is widely used by the Micmac. The blue flag is an emetic, and was used by the Micmac to help the stomach rid itself of poisonous substances. The fresh root has a bitter taste and can be dangerous if taken in large doses. In lesser doses it induces vomiting and considerable nausea. I do not recommend experimenting with this plant. A common Micmac name for the plant is “Beaver Root”.
