What have sailors used since 1495 to avoid getting scurvy?

During the great geographical discoveries, ships went to unknown lands. They were at sea for a long time. The most terrible scourge for the crews was scurvy. A terrible disease that claimed more than one hundred sailors. At a great distance from the land, where there was not enough plant food, the disease progressed rapidly. In order to save themselves, the sailors cooked spruce broths and citrus fruits, which they stocked up on the route to the south. On the expedition to the north, the pioneers tried to stock up on fresh meat and fish. Bear’s blood was also considered a preventive medicine.
