Colchicine comes from the autumn crocus, a plant with purple flowers. Discovered by the Egyptians around 1200 B.C.E., it mainly grows in mountainous regions in Europe but can also be found in Asia and Africa. This plant can reach up to 40 centimetres in height and live for several years.
Colchicine, which is extracted from the bulb and seeds of the flower, has been shown to have anti-inflammatory properties.
