Colchicum

May 13th, 2007

The Botanical name is Colchicum Luteum. Indian name is Hirantutia. Colchicum is an annual herb with brownish fleshy under ground stems. It is almost conical in shape,flattened on one side and round on the other.The plant has very narrow leaves, large flowers and fruits with recurved tips.

Colchicums are native to Europe and northern Africa. The scientific name comes from Colchis, an ancient country bordering on the Black Sea, now part of the Georgian Republic, where colchicums are abundant.

The chief constituents of Colchicum is the alkaloid,colchicine,which occur in the form of yellow flakes,crystals or as whitish yellow amorphous powder.

Colchicum is a genus of flowering plants containing around sixty species of perennial plants which grow from corms. It is a member of family Colchicaceae, and is native to West Asia and part of the Mediterranean coast.

Colchicum autumnale, commonly called “autumn crocus” or “naked ladies”, is the best known species. It produces purple, pink or white flowers resembling those of the crocus which appear from September to October in its native latitudes. It forms a rosette of dark green leaves, but only after flowering.

Several other species, such as C. speciosum, C. album, C. corsicum and C. agrippinum, are grown for their flowers.

Its leaves, corm and seeds are poisonous, containing the alkaloid colchicine. Its roots and seeds have long been considered to have valuable medicinal properties deriving from the use of small doses of this drug, such as to treat gout.

In this genus the ovary of the flower is underground. As a consequence, the styles are extremely long in proportion, often more than 10cm.

In the UK, the National Collection of Cochicums is maintained at Felbrigg Hall, Norfolk.

Colchicums should be planted immediately after delivery in August or September. (They often bloom in their shipping container if not planted immediately.) Plant the corms in well- drained soils in full sun to partial shade. Good planting sites include naturalized areas under the filtered shade of large trees and shrubs, in rock gardens, or among low-growing groundcovers such as sedum. For the best visual display, plant colchicums in clumps. The corms should be planted 2 to 3 inches deep and 6 inches apart.

Colchicum autumnale is most commonly known as autumn crocus, but in various regions it is known as naked-ladies, colchicum, and meadow saffron. It should be noted that it’s not a crocus, and it’s not saffron, and should definitely not be used in place of saffron in cooking because eating any part of this plant can kill you.

The autumn crocus is native to Europe but has been introduced to Canada and the U.S., where it is both grown in gardens and lives as a wild escapee in meadows and woodlands. It’s a perennial herb in the lily family (Liliaceae) which grows from a corm (a solid bulb) that can unfortunately be mistaken for a wild onion. The rapierlike leaves grow about a foot high, and in the early fall one or two leafless stalks sprout from the corm; each stalk produces a single white-to-purplish-pink flower that resembles a crocus.

The extreme toxicity of this plant has been known since the times of ancient Greece, but in the fifth century, herbalists in the Byzantine Empire discovered it could be used to treat rheumatism and arthritis, and the Arabs began to use it for gout. The useful active ingredient in the plant is an alkaloid called colchicine, which is still used to treat gout and which has anticancer properties.

Poisoning from this plant resembles arsenic poisoning; the symptoms (which occur 2 to 5 hours after the plant has been eaten) include burning in the mouth and throat, diarrhea, stomach pain, vomiting, and kidney failure. Death from respiratory failure often follows. Less than than two grams of the seeds is enough to kill a child; a specific antidote doesn’t exist, so treatment typically involves giving the victim activated charcoal or pumping the stomach.
