Scourge of Black-leg (Scurvy) on the Mormon Trail
For years, scurvy has been perceived as a disease occuring at sea. In England, it was recognized in 1843 that potatoes could prevent scurvy. While in Winter Quarters in 1846-47, the Saints contracted scurvy and considerable numbers died from its effects. George A. Smith enjoined the Saints to eat potatoes and many lives were saved.
