REGIONAL NAMES English - Kuth, costus Hindi - Kuth, Kur Malayalam -Kottam, Simakottam Kannada - Kostha Tamil - Kostam Telugu - Kostamu, cengala DISTRIBUTION It is found in Himachal Pradesh, Uttaranchal, Jammu & Kashmir, Sikkim and Arunachal Pradesh PART USED : Tuberous Root MEDICINAL PROPERTIES AND USES The roots are bitter, acrid, sweet, thermogenic, aromatic, deodorant, aphrodisiac, anodyne, carminative, digestive, stomachic, diaphorectic, stimulant, alterant, depurative, galactogogue, diuretic, disinfectant, expectorant, febrifuge, rejuvenating and tonic. They are useful in chronic and foul ulcers, leprosy, leucoderma, pruritis, amenorrhoea etc. CULTIVATION AND PROPAGATION : SOIL AND CLIMATE Sandy textured loam soil, rich in moisture and organic carbon is best for germination as well as for the better survival of seedlings and productivity. The plant grows in temperate and sub-alpine region. NURSERY RAISING AND PLANTING Cultivation and nursery of Kuth in Bio-edaphic condition at an altitude of 1200-1800 m is suitable. The seeds are sown in April or May in nursery. When the seedlings are + 15 cm long, these are transplanted in fields. MANURE/FERTILIZER Well-decomposed farmyard manure should be applied to nursery beds and in the field at the time of field preparation. IRRIGATION The crop requires 5-6 irrigations between May & September. The land is irrigated when seeds are sprouting. HARVESTING/POST HARVESTING OPERATION Mature tubers develop in 2-3 years. However, yield is obtained from 3 years old crop. Root is harvested in early September or October or early spring. The roots are cleaned with water and dried for processing.
