Acorus calamus, from Manipur.


I hope this is the plant which has high amount of Beta-asarone which give its rhizome and leave scented.


Ya …, both rhizomes as well as leaves are aromatic. As you know it has got high reputation as a medicinal plant too, used for various stomach ailments in children traditionally. Every household will have this precious plant (rhizome) for emergency use.

Here are mine from Herbal garden samalkha Panipat. Attachments (2)


Calamus derived herbal products were banned in USA as far back as 1968…. because of purported carcinogenicity… apparently there are genetic variations …
I quote from Wikipedia: (do not know whao wrote this wiki article though)
Start Quote: ”  Regulation: Products derived from Acorus calamus were banned in 1968 as food additives by the United States Food and
Drug Administration. [1] The questionable chemical derived from the plant was β-asarone. Confusion exists whether all strains of Acorus
Calamus contain this substance.
Four varieties of Acorus calamus strains exist in nature; diploid, triploid, tetraploid and hexaploid. [2] Diploids do not produce the carcinogenic β-asarone. Diploids are known to grow naturally in Eastern Asia (Mongolia and C Siberia) and North America. The triploid cytotype probably originated in the Himalayan region, as a hybrid between the diploid and tetraploid cytotypes. [3] The North American Calamus is known as Acorus Calamus var. americanus or more recently as simply Acorus americanus. Like the diploid strains of calamus in parts of the Himalayas, Mongolia, and C Siberia, the North American diploid strain does not contain the carcinogenic β-asarone.[4][5][6] Research has consistently demonstrated that “β-asarone was not detectable in the North American spontaneous diploid Acorus [Calamus var. americanus]”.[

the quote is from URL: http://en.wikipedia.org/wiki/Acorus and that’s where the references listed in the quotes are…
MY QUESTION: ARE THERE INDIAN ORIGIN PAPERS ABOUT the GENETICS of CALAMUS or VACHA used in Ayurvedic medicine ???
IF anyone knows, could you please share the CITATIONS WITH THE GROUP and ME?

Acorus calamus. Known as ‘Bach’, ‘bare’, ‘barian’ this once very common floristic element along water courses/ ditches/ lakes in Himachal upto about 2500 m asl, is getting scarcer due to degradation of its habitat. Its rhizomes are considered medicinally very important and form part of State’s folklore for the purpose. One such folk belief is “Jithe bana, basuti, bare; uthe manus koi kian mare” (where you find threesome of Vitex negundo, Adhatoda vasica and Acorus calamus, how can a man die of disease).
This image clicked from typical habitat of the species in Kullu district. May also note a spadix in the image.


Thanks … for this very interesting quote…your picture is from wild, I could not get this in wild till now…


Thanks very much … 
Yes you are right… all my photographs are from the wild, clicked during my various field visits to forests…
You may see wild populations of Acorus calamus at Renuka ji lake (Sirmour dist.), Prashar lake (Mandi dist.), road side ditches from Kullu to Manali and various other locations. 


Never saw this plant in wild. Thanks for sharing …

Interesting folklore too,
