Lettuce
$1.79
Common lettuce, Lactuca sativa, has its origins in the Middle East. Egyptian wall murals of Min, the god of fertility, depict lettuce in cultivation in about 2700 B.C. The erect plant — similar to modern romaine, with a thick stem and milky sap — had sexual connotations. Min consumed lettuce as a sacred food for sexual stamina, and ordinary Egyptians used the oil of the wild seeds for medicine, cooking, and mummification.
