Acorus calamus L. is a perennial & rhizomatous herb growing on marshy places. Leaves are bright green, 15 - 25 cm long and 0.2 - 0.5 cm broad, uniform with distinct midrib. Flowers small, yellow green arranged in cylindrical spandex. Known since biblical times, the aromatic rhizome (underground stem) of Acorus calamus L. is commonly referred to as calamus or sweet flag, Bhojo in Nepali. Calamus has been taken over the centuries as a remedy for various sorts of digestive upsets and colic, especially in children. They are harvested in late autumn or early spring and are dried for later use. The dry root loses 70% of its weight, but has an improved smell and taste.
The rhizomes of calamus are considered to possess anti-spasmodic, carminative and anthelmintic properties. They are used for the treatment of a host of diseases such as epilepsy and other mental ailments, chronic diarrhoea, dysentery, bronchial catarrh, intermittent fevers, glandular and abdominal tumours. They are also used to treat kidney and liver troubles, rheumatism and eczema.
Chewing the root is said to kill the taste for tobacco. Roots 2 - 3 years old are used since older roots tend to become tough and hollow.
