In 1601 the crew of one ship (out of four) during an East India Company voyage were each given 3 teaspoons of lemon juice daily. The crew on the other 3 boats weren't. At the Cape of Good Hope 110 out of 278 had died mostly from scurvy. The crew receiving lemon juice remained largely healthy.
In 1795 the British Royal Navy bgins using citrus on a regular basis, wiping out scury.
In 1865 British merchant marine sailors were finally given citrus juice and scurvy was eliminated.
