Product Description


Biological Name: Acorus calamus

Aroideae family

Other Names: Calamus, Vacha, Bach, Agri-turki, Baje, Sweet Flag



Calamus is found all over the world. It is a semi-aquatic perennial cultivated in damp marshy places in India and Burma. Exceedingly common in Manipur and the Naga Hills of India, and on the edges of lakes and streams.


Flower and Fruit: Green flowers, like small dice, form a tightly packed, slim, conical spadix. The plant does not produce any fruit. It propagates from the rhizome.


Leaves, Stem and Root: The plant grows from 60 to 100 cm tall. The stem is triangular and sprouts from a horizontal, round root-stock, which has the thickness of a thumb. The upper shoot forms a grooved flower sheath. The leaves are oblong, sword-shaped and arranged in two rows. The leaves have no stems.


Characteristics: The rhizome has an intensely aromatic fragrance and a tangy, pungent and bitter taste. The leaves often undulate on the margins.




  • acorin – a volatile essential oil. It is a honey-like liquid, very bitter and aromatic, soluble in alcohol, chloroform, ether, splitting into sugar and volatile oil.
  • acoretin (choline) – a bitter principle. It is a resin-like body.
  • Calamine ( useful in dysentery). It is a crystalline alkaloid soluble in alcohol and chloroform.
  • starch
  • mucilage
  • a little of tannin.

The dried rhizome yields 1.5 per cent to 2.7 per cent of a neutral, yellow, aromatic, essential oil. The fresh aerial parts yield about 0.123 per cent of the volatile oil. The unpeeled roots yield the most – from 1.5 to 3.5 per cent.

The essential volatile oil of Acorus Calamus is yellowish-brown, and is found to be composed of asaryl aldehyde, free normal heptylic and palmitic acid, eugenol, esters of acetic and palmitic acids, pinene, camphene, sesqui-terpene, calamene, and a small quantity of phenol, Eugenol, Methyl Eugenol, Cilamenenol and Calameone.

The chief constituents are heavily dependent upon the chemical strain (di-, tri-, tetraploid); beta-asarone (cis-isoasarone), alpha- and gamma-asarone, beta- gurjuns, acorone (bitter), ZZ-Deca-4,7-dienal (odor-determining)
