Siddha/Tamil: Kumgumappoo (dried stigma).
Action: Stigma and style—nervine tonic, sedative, antispasmodic expectorant (in dry cough, whooping cough, bronchitis), stomachic, diaphoretic, emmenagogue.
The Ayurvedic Pharmacopoeia of India indicated the use of the stigma and style in migraine, chronic sinusitis, and in urinary obstruction, inflammation of the urinary tract.The saffron is used in Chinese medicine for melancholia, depression, shock and menstrual disorders.Saffron contains a volatile oil composed of terpenes, terpene alcohols and esters. The herb also contains crocin, picrocrocin, crocetin, carotenoids and riboflavin and thiamine.Preliminary evidence suggests that crocetin may improved atherosclerosis by increasing plasma oxygen diffusion and decreasing cholesterol and triglyceride levels. In addition, cro- cetin binds to albumin, potentially increasing oxygen diffusion and improving atherosclerosis. (Natural Medicines Comprehensive Database, 2007.)The stigma showed remarkable inhibitory effect on blood coagulation due to the presence of platelet aggregation inhibitor containing adenosine. It accelerated in vitro fibrinolytic activity of urokinase and plasmin.Small amounts of Saffron stimulate gastric secretion; larger amounts stimulate uterine smooth muscle and exhibit emmenagogue and abortifacient effects.Saffron extract showed cytotoxic and antimutagenic activity and antitu- mour activity against ascites tumours in mice. Chemical analysis indicated that the naturally occurring crocin may be the active principle responsible for the observed anticancer activity.A xanthone, carotenoid glycosidic conjugate, mangi-crocin, isolated from saffron, showed significant adapto- genic activity. A natural antioxidant, isolated from saffron stem callus, showed better antioxidant activity than vitamin E. Saffron bulbs are toxic, stigmas in overdoses narcotic.The dose of stigma and styles at 1.55.0 g is toxic. (Recommended dose : 0.5-1.5 g per day).
Dosage: Dried style and stigma—20-50 mg (API Vol. IV.)... crocus sativus

They are also given in gastric complaints. They help to remove blood clots and other purulent matter in the body. The juice of the tubers is given in dropsical affections of hands and feet, and of effusions in joints. The juice causes salivation and vomiting. In Ayurveda, the improvement formulations using the herb are Chyavanaprasam, Asokarishtam, Baladthatryaditailam, Kalyanakaghritham, etc. The drug “HALLAKAM” prepared from this is in popular use in the form of powder or as an ointment application to wounds and bruises to reduce swellings. It also improves complexion and cures burning sensation, mental disorders and insomnia (NRF, 1998; Sivarajan et al, 1994).Distribution: The plant is distributed in the tropics and sub-tropics of Asia and Africa. The plant grows wild in shaded areas which are wet or humid, especially in forests in South India. It grows in gardens and is known for their beautiful flowers and foliage. It is also cultivated as an intercrop with other commercial crops.Botany: Kaempferia rotunda Linn. belonging to the family Zingiberaceae is an aromatic herb with tuberous root-stalk and very short stem. Leaves are simple, few, erect, oblong or ovate- lanceolate, acuminate, 30cm long, 10cm wide, variegated green above and tinged with purple below. Flowers are fragrant, white, tip purple or lilac arranged in crowded spikes opening successively. The plant produces a subglobose tuberous rhizome from which many roots bearing small oblong or rounded tubers arise (Warrier et al, 1995).Agrotechnology: The plant is a tropical one adapted for tropical climate. Rich loamy soil having good drainage is ideal for the plant. Laterite soil with heavy organic manure application is also well suited. Planting is done in May-June with the receipt of 4 or 5 pre-monsoon showers. The seed rate recommended is 1500-2000kg rhizomes/ha. Whole or split rhizome with one healthy sprout is the planting material. Well developed healthy and disease free rhizomes with the attached root tubers are selected for planting. Rhizomes can be stored in cool dry place or pits dug under shade plastered with mud or cowdung. The field is ploughed to a fine tilth, mixed with organic manure at 10-15t/ha. Seed beds are prepared at a size of 1m breadth and convenient length. Pits are made at 20cm spacing in which 5cm long pieces of rhizomes are planted. Pits are covered with organic manure. They are then covered with rotten straw or leaves. Apply FYM or compost as basal dose at 20 t/ha either by broadcasting and ploughing or by covering the seed in pits after planting. Apply fertilisers at the rate of 50:50:50 kg N, P2O5 and K2O/ha at the time of first and second weeding. After planting, mulch the beds with dry or green leaves at 15 t/ha. During heavy rainy months, leaf rot disease occurs which can be controlled by drenching 1% Bordeaux mixture. The crop can be harvested after 7 months maturity. Drying up of the leaves is the indication of maturity. Harvest the crop carefully without cutting the rhizome, remove dried leaves and roots. Wash the rhizome in water. They are stored in moisture-proof sheds. Prolonged storage may cause insect and fungus attack (Prasad et al, 1997).Properties and activity: The tubers contain crotepoxide and -sitosterol. Tuber contains essential oil which give a compound with melting point 149oC which yielded benzoic acid on hydrolysis.The tubers are acrid, thermogenic aromatic, stomachic, antiinflammatory, sialagogue, emetic, antitumour and vulnerary.... indian crocus
