An erect plant 1.2- 2.7 m high; rootstock tuberous, insipid; stem sub woody at the base. Leaves 15- 30 by 5.7- 7.5 cm, sub sessile, spirally arranged, oblong or oblanceolate- oblong, acute or acuminate, often cuspidate, glabrous above, silky-pubescent beneath, base rounded; sheaths coriaceous; ligule- 0. Flowers white, numerous, in very dense spikes 5- 12.5 by 3.8- 7.5 cm; bracts 2- 3.2 cm long, ovate, acuminate, often pungently mucronate, bright red; bracteole solitary below the calyx, 1.6 mm long.

Phytochemistry

Two new quinones- dihydrophytylplasto-2-uinone and its 6- methyl derivative- along with a tocopherolquinone and 5α- stigmast- 9 (11) en- 3β- ol isolated from seeds and their structures elucidated (Phytochemistry 1984, 23, 1725); methyl hexadecnoate, methyl octadecanoate and tetracosanyl octadecanoate isolated from seeds (Indian J.Pharm. Sci. 1984, 46, 150); a tocopherol isolated from seeds and identified as G2- tocopherol; five new compounds- tetradecyl13- methylpentadecanoate,tetradecyl11- methyltridecanoate,14- oxotricosanoid- acid,14- oxoheptacosanoid acid and 15 oxoctacosanoid acid- isolated from rhizomes and characterized (Phytochemistry 1986, 25, 1899); seed oil (6.0%) consisted of palmitic (55.97), oleic (23.75%), linoleic, stearic, myristic and lauric acids. Defatted seeds contained diosgenin, glucose, galactose and rhamnose (Indian For. 1986, 112,

135; Chem.Abstr. 1987, 106, 99407e); 31- norcyicoartanone, cycloartanol, cycloartenol and cyclolaudenol isolated from roots (Planta Med. 1988, 54, 268); methyl 3- ( 4- hydroxyphenyl ) -2E propanoate isolated from rhizomes (Planta Med. 1988, 54, 477).

Medicinal  
Ayurvedic The root is pungent, bitter; useful in bronchitis, fever, "Kapha" and "Vata". Dyspepsia, inflammation, anemia, rheumatism, lumbago, hiccough.
Unani  
Traditional

Rhizome mixed with sugar is used in venereal diseases.

Others The underground tubers are now considered as a source of Diosgenin, the precursor of steroids, including sex hormones and oral contraceptives. Also, a tonic and anthelmintic may be obtained from it. The extract from the tubers and stem is given orally (usually at morning time, empty stomach) to cure the urinary tract infections and inflammation. In the united provinces, from the root a strengthening tonic is made, and it is also used as an anthelmintic. In Bengal and in the Konkan, the root is considered depurative and aphrodisiac.
