Background

Acorus calamus L. (family Araceae/Acoraceae) has long, narrow leaves and an aromatic rootstock. It is similar to the iris in appearance and can be found in moist habitats such as the banks of ponds or streams and swamps in North America, Europe, and Asia.

Traditional medicine includes use of the rhizome and the herb's main traditional uses include therapy for colic, dyspepsia (upset stomach), and flatulence (gas). In Ayurveda there is major use of calamus for diseases of the kidney and liver, eczema, rheumatism, and enhancement of memory. Currently, traditional uses lack substantiation in the available medical literature. Vomiting was the primary toxicity reported following use of the root for assumed production of euphoria.
