Citrus x limon

When Sir Edmund Hillary and Tensing Norkay set out to scale Mt. Everest, they made sure to pack enough lemon powder for their journey. These famous mountaineers used it to make lemonade, which they drank for energy. Lemons are a rich source of Vitamin C, believed to support your body's natural defense system. Lemons have also been used by sailors to prevent scurvy since at least 1700, when an English law decreed that every ship leaving port for foreign lands must have a supply of lemon or lime juice on board. That's how sailors first got the name "limeys," in fact. Whether you're climbing mountains or stairs, a bit of lemon might help make the trip to the top a bit more sunny!

Commonly called: whole dried lemons, lemon verbena
