Anodyne Antibacterial Antispasmodic Aphrodisiac Carminative Emmenagogue Skin Stimulant
Tonic Vermifuge
Costus is a commonly used medicinal herb in China and is considered to be one of their 50 fundamental herbs[218]. It is also used in Ayurvedic medicine where it is valued mainly for its tonic, stimulant and antiseptic properties[254]. It is said to be aphrodisiac and to be able to prevent the hair turning grey[254]. The root is anodyne, antibacterial, antispasmodic, aphrodisiac, carminative, skin, stimulant, stomachic, tonic and vermifuge[61, 147, 176, 218]. It is used internally in the treatment of abdominal distension and pain, chest pains due to liver problems and jaundice, gall bladder pain, constipation associated with energy stagnation, and asthma[238]. The root is harvested in the autumn or spring and either dried for later use or decocted for the essential oil[238]. It is normally used with other herbs[218]. The root is also used in Tibetan medicine where it is considered to have an acrid, sweet and bitter taste with a neutral potency[241]. It is used in the treatment of swelling and fullness of the stomach, blockage and irregular menses, pulmonary disorders, difficulty in swallowing and rotting/wasting of muscle tissues[241]. An oil from the root is very beneficial in the treatment of rheumatism[211].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.
An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Other Uses
Essential Hair Incense
An essential oil obtained from the roots is used medicinally, in perfumery, incenses and as a hair rinse when it is said to darken grey hair[61]. It has a strong lingering scent[238]. The smell is at first like violets, but as it ages it can become more fur-like or eventually become unpleasantly goat-like[245]. The roots are cut into lengths about 8cm long and then dried before being exported[211]. Smaller pieces of the root are ground into a powder and then used to make incense sticks[211]. The longer clean pieces are cut into very thin slices and then burnt at shrines or used as a tonic in hot baths[211].

Cultivation details
Succeeds in most soils in a sunny well-drained position[1]. Cultivated as a medicinal plant and for its use in perfumery in the Himalayas[51, 245]. The dried root has something of the mossy smell of violets when fresh, becoming fur-like or even unpleasantly goat-like with age[245]. Most of the roots are exported to China and Japan and the plant forms quite a large article of commerce in Kashmir, the trade being controlled by the State[211]. Wild plants have been greatly over-collected and the plant has been placed on the CITES I list of endangered species - it is now illegal to dig them up for export[238].

Propagation
Seed - we have no information for this species but suggest sowing the seed in a cold frame in the spring. Surface sow, or only just cover the seed, and make sure that the compost does not dry out. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse or cold frame for their first winter. Plant them out in late spring after the last expected frosts. Division in spring might be possible.
