Calamus Overview

Calamus Calamus is a grass-like plant commonly mostly commonly found in Eastern Europe in swamps or along the banks of waterways. Calamus has traditionally been used in both Ayurdevic and Chinese medicine for a number of ailments, including digestive disorders including colic, ulcers, gastritis, flatulence, diarrhea, intestinal infections, dyspepsia, and anorexia. It is also used to induce vomiting, induce sweating, improve memory and for the treatment of inflammatory disorders. The FDA does not allow calamus in food due research showing it has carcinogenic effects, likely due to the beta-asarone content, which can vary heavily depending on the species.
