Our love affair with this member of the Lily family dates back hundreds of years. Asparagus "stirs up lust in man and woman," wrote English herbalist Nicholas Culpepper in the 17th century. In 19th-century France, bridegrooms were served three courses of the sexy spears at their prenuptial dinner. Apparently for a good reason: asparagus is a great source of potassium, fiber, vitamin B6, vitamins A and C, and thiamin and folic acid. The latter is said to boost histamine production necessary for the ability to reach orgasm in both sexes.
