Castor oil has long been used throughout history. It was reportedly used for medicinal purposes in Ancient Egypt and in the early middle Ages in Europe. It was then regarded as a folk medicine.
Edgar Cayce, who authored the Encyclopedia of Healing, said that castor oil supported the healing of the small intestines, particularly the lymphatic tissue – this allowed for tissue growth and repair.
In the recent centuries, Natural castor oil (also sometimes referred to as caster oil) was at first identified as a laxative and as a lubricant.
Mothers used to feed it to their children as a relief for tummy aches. When taken orally, castor oil helped ease the pain of constipation and mild diarrhoea.
On the other hand, it was used to lubricate the wheels of wagons and carts. It was also used as an aircraft lubricant during the First World War.
Castor oil's used in far and wide areas. It has explored every field imaginable and has found a niche in each one.
