The real name for Canola oil is LEAR, or Low Erucic Acid Rape, as it has been extracted from Rapeseed oil. This oil is in fact an industrial oil product which has no place whatsoever in our bodies. In light industry, it is also referred to as penetrating oil. Rapeseed oil is also the source for Mustard Gas, which was used as a chemical warfare agent, and was banned after World War 1 for causing severe blistering of the lungs and skin.
