Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Calamus rhizome (Acorus calamus), also known as sweet flag, is used in traditional medicine systems such as Ayurveda, Traditional Chinese Medicine (TCM), and various folk medicines. Its application for digestive complaints, including symptoms compatible with Irritable Bowel Syndrome (IBS)—such as bloating, gas, and abdominal discomfort—has a long history. In Ayurvedic practice, calamus is believed to stimulate appetite, improve digestion, and relieve gastrointestinal spasms. However, there is a marked lack of robust modern clinical trials specifically evaluating calamus rhizome for IBS. Most available scientific literature focuses on its general antispasmodic, carminative, and anti-inflammatory properties, but these are based on in vitro or animal studies, not well-controlled human trials. Furthermore, safety concerns have been raised due to the presence of β-asarone, a compound found in some calamus varieties, which is considered potentially carcinogenic. Regulatory restrictions on calamus (especially the β-asarone-containing varieties) further limit its widespread use as a therapeutic agent for IBS. In summary, while calamus rhizome has traditional use for digestive ailments, there is little to no high-quality clinical evidence to justify its specific use for IBS, and safety concerns remain significant.
