Acorus calamus aka Sweet Flag

Taxonomy ID: 14169

Acorus calamus, also known as sweet flag, sway or muskrat root, is a tall wetland monocot plant belonging to the family Acoraceae and the genus Acorus. It has been used in traditional medicine for centuries to treat digestive disorders and pain, although there is no clinical evidence to support its safety or efficacy. In fact, ingesting calamus may be toxic, which led to its commercial ban in the United States. This spreading, tufted herbaceous perennial has aromatic, sword-shaped leaves that are longitudinally striped with creamy-white. Acorus calamus has flat iris-like leaves and slowly spreads through branching, creeping rhizomes. It thrives in moist to wet soil rich in organic matter and can tolerate standing water, making it suitable for wetland environments.
