Characteristics, form of production and uses of castor oil
What is castor oil?
Castor oil is obtained from seeds of castor oil plant. Special care must be taken because these seeds, besides providing about 50% of castor oil, also contain a toxic substance.
Why unrefined castor oil is toxic?
This toxic substance is formed by a very harmful vegetable protein, a lectin called ricin, considered a toxoalbumin or phytotoxin.
In addition, it also contains alkaloids harmful to our bodies, ricinine and ricidine, with high toxic effect, which may trigger allergic reactions by contact and even death, by ingestion in small doses.
Because of its composition, since it is a glycoprotein substance, can also cause allergic reactions to our body, and, as it blocks protein synthesis in the body, especially the intestine, it is a potent poison.

How do you obtain edible castor oil?
The seeds of castor oil plant are subjected to heat to extract the castor oil. All toxic substances contained in the oil are eliminated, resulting completely fit for human consumption because poisons are destroyed by heat.
The excess mass is usually discarded, since it still retains these toxic properties.
