Ayurvedic: Mushali, (white var.), Mahaashataavari. The black variety is equated with Taalamuuli, Chlorophytum arundinaceum Baker.

Unani: Shaqaaqul-e-Hindi.

Action: A substitute for A. officinalis.

The root yields asparagin. Sapoge- nins A and B, isolated from the root, were identified as stigmasterol and sarsasapogenin.

Action: Diuretic, laxative, car- diotonic, sedative, galactagogue; used for neuritis and rheumatism, as well as for cystitis and pyelitis.

Key application: In irrigation therapy for inflammatory diseases of the urinary tract and for prevention of kidney stones. (German Commission E.). It is contraindicated in kidney diseases and oedema because of functional heart.

The root contains steroidal glyco- sides (asparagosides) and bitter glyco- sides; asparagusic acid and its derivatives; asparagines, arginine and ty- rosine; flavonoids, including rutin, kaempferol and quercetrin; polysac- carides and inulin. Asparagine is a strong diuretic source of folic acid and selenium.

A spirostanol glycoside, isolated from the methanolic extract of the fruits, has shown 100% immobilization of human spermatozoa.

Dosage: Root—3-5 g powder. (CCRAS.)... asparagus adscendens

Along with other therapeutic applications, The Ayurvedic Pharmacopoeia of India indicates the use of the tuberous root in gout, puerperal diseases, lactic disorders, haematuria, bleeding disorders and also recommends it for hyperacidity.

The plant contains saponins—sha- tavarins I-IV. Shatavarin IV is a glycoside of sarsasapogenin. The saponin in doses of 20-500 mcg/ml produces a special blockade of syntocinon (oxy- tocin)-induced contraction of rat, guinea-pig and rabbit uteri in vitro and in situ. It also blocks the uterine spontaneous motility.

The dried root yields sitosterol; 4,6- dihydroxy-2-O-(2' hydroxyisobutyl) benzaldehyde and undecanyl cetano- ate, and contains a large amount of saccharine matter, mucilage and miner- als—Ca (0.172), Cu (0.033), Na (14.60), K (8.32), Mg (0.169), Mn (0.0074), Ni (0.105) and Zn (0.072) mg/g(dry weight).

The root was found to reduce gastric emptying time comparable to that of metoclopramide. (J Postgrad Med, 1990, 36(2), 91-94).

The root extracts exhibited antiallergic activity in animal studies.

The root, when fed orally, acted as immunomodulator against induced sepsis and peritonitis in rats and mice.... asparagus racemosus
