Acorus calamus

Acorus calamus is a perennial plant that belongs to the Acoraceae family. It is commonly known as sweet flag or calamus, among other names. The plant is native to Asia, Europe, and North America, and is known for its distinctive sweet, aromatic scent.

Description[edit | edit source]

The Acorus calamus plant typically grows to a height of 1-1.5 meters. It features sword-shaped leaves and a solid, cylindrical rhizome, which is horizontally creeping under the ground. The plant's inflorescence is a spadix, which is a type of flower spike that is enveloped by a leaf-like bract. The flowers of the Acorus calamus are small and densely packed on the spadix.

Cultivation and Uses[edit | edit source]

Acorus calamus is often cultivated for its rhizomes, which are used in traditional medicine, perfumery, and to flavor beverages and candies. In Ayurveda, the rhizomes are used for their supposed medicinal properties, including as a sedative, analgesic, and antispasmodic. However, the safety and efficacy of these uses have not been scientifically confirmed.

In addition to its uses in medicine and perfumery, Acorus calamus is also used in landscaping and gardening due to its attractive foliage and sweet scent. It is often planted in water gardens and along the edges of ponds.

Toxicity[edit | edit source]

The rhizomes of Acorus calamus contain beta-asarone, a compound that has been found to be potentially carcinogenic. As such, the consumption of Acorus calamus is regulated in some countries, including the United States and Canada.
