In olden days many sailors got scurvy. It was a real problem for the seamen but no one knew what was causing it.
In the 1500’s one ship’s captain found a witchdoctor in Newfoundland that had a magic potion of pine needles that cured his sailors.
In 1747 a Doctor James Lind thought that the disease might be caused by the poor diet the sailors were eating so he tried an experiment.
He divided some of the sailors into pairs and added the following things to each pairs diet.
2 had cider 2 had vinegar 2 had acid, alcohol ginger and
cinnamon 2 had garlic, mustard
and herbs 2 had seawater 2 had oranges and
lemons
