 **Acorus calamus rhizome**, Calamus: The dried rhizome and also the calamus oil are ancient remedies against gastro-intestinal disorders. The drug was introduced to Europe in the 16th century, coming from India. The rhizome is cutted into pieces after cleaning and dried at moderate temperatures (up to 35 deg.). Sometimes it is peeled before drying. Calamus has an aromatic odor, it tastes spicy, pungent and bitter. \\ **Acorus calamus rhizome**, Calamus: The dried rhizome and also the calamus oil are ancient remedies against gastro-intestinal disorders.

-Constituents. Volatile oil (1-5%, tetraploids also more) with more or less β-asarone, ranging from 0-82%,  [CRC; Wichtl; Keller K, Stahl E, DAZ 122,(1982), 2463; Keller K, Stahl E, Planta Med 47,(1983), 71; Stahl E, Keller K, Planta Med 43,(1981), 128 ], or isoeugenol methyl ether as the main constituents, also the sesquiterpenes calamendiol and isocalamendiol. As mentioned above, the occurence of beta-asarone depends on the variety of calamus and is of great importance to users, as possible carcinogenic effects of the substance in man can not be excluded.

Li M, Jiang Z, Variations of the essential oils in Acorus calamus L. and their major constituents, Zhongguo Zhonqyao Zazhi 19(5), (1994), pp.274-6) - also showing June to best the best season for A. calamus cropping]. \\+Constituents.

The triploid race (Eastern Europe) contained a limited amount of β-asarone varying from 3-8% (Stahl, E. and Keller, K., Planta Medica 43:128-140, 1981); see also [Bertea, Cinzia M., et al. "Identification of an EcoRI restriction site for a rapid and precise determination of β-asarone-free Acorus calamus cytotypes." Phytochemistry 66.5 (2005): 507-514] \\
