Tacitus has praised the virtues of linseed it the 1st century. The benefits if its use was being realised rapidly, so much so that Charlemange passed ‘Law and Regulations’ requiring the consumption of linseed. The ancient Portuguese books mention about linseed being used for treatment of wounds. The linen mentioned in the Bible is also believed to have been made of linseed.
