Cod liver oil
Cod liver oil is a dietary supplement derived from liver of cod fish. It contains the omega-3 fatty acids, vitamin A and vitamin D. Historically, it was given to children because vitamin D had been shown to prevent rickets, a consequence of vitamin D deficiency.
The substance was squeezed from fermenting cod livers. It was known and feared for its terrible taste. From the 19th century until the mid-20th century, cod liver oil was found in most European households and many children would be made to swallow a spoonful of cod liver oil daily.
Use for punishment
Because of its foul taste, cod liver oil was also sometimes given for punishment in households that had otherwise abandoned its use, similar to how castor oil was sometimes used as punishment in the United States. Cod liver oil however is not a laxative like castor oil.
