It is an old tradition to use cod livers to extract oil. In Iceland fishermen used to store livers in a container or in a hole in the ground outside their homes. By time the livers released the oil which was then removed with a scoop and put into bottles. During winter each family member took in a tablespoon or a good sip from the bottle. It was believed that this pure natural oil made people healthier, stronger and enabled them to endure the long and cold Nordic winters. The word Dropi comes from Old Norse and means a drop.
