A useful wetland native, it has traditionally been prepared for a sweet and a flavoring, and has a wide variety of medicinal uses. Toxic compounds are present in the root as well, so thorough research and consultation with experienced plant-medicine practitioners should be considered before using the plant, as always. 

PFAF, notes “sweet flag has a very long history of medicinal use in many herbal traditions. It is widely employed in modern herbal medicine as an aromatic stimulant and mild tonic. In Ayurveda it is highly valued as a rejuvenator for the brain and nervous system and as a remedy for digestive disorders. However, some care should be taken in its use since some forms of the plant might be carcinogenic.”

It’s also been used in homeopathic and Native North American traditional medicines. In the home garden Sweet Flag belongs in a damp spot, perhaps a rain garden basin, or even a pond edge. It can be mistaken for Iris of even Cattails as it emerges in the water.
