Castor Seeds


The history of castor plant is not very clear. It is said that this plant originated in the tropical belt of India and Africa. The Sanskrit language gave the ancient name of castor i.e. ‘Eranda’. It was also called by various other names in different languages. Herodotus, the father of history, stated that the Egyptians used a type of oil to burn their lamps and for other purposes, which was made by the seeds of Ricinus in the fourth century BC. He named it Kiki and till now castor is cultivated in Greece by the same name.
Theophrastus and Dioscorides, who stated that the oil of the plant is not worth eating but is very good if applied externally as a medicine, gave the detailed description of the plant at around 1st century. They also stated the process of extracting oil from the seeds of the plant. This plant was cultivated till fifteenth century but due to the negative impacts that it has, it slowly started becoming unpopular and by the eighteenth century, its production practically ceased in Europe and the countries started fulfilling their requirements by importing the oil from Jamaica. This is the period in which its name changed to castor. The dark side of this plant oil was observed in the fascist Italy when under the leadership of Mussolini, castor oil was used to give punishments to the people who opposed the established fascist government. They were forced to consume this oil that in turn leads them to death.
Castor is produced in about 30 countries lying in the tropical belt of the world. The production of this crop is concentrated in the hands of a fewer countries and that is why the world production of castor and its derivatives is highly fluctuating.
