Maca, "Lepidium meyenii", is an annual plant which produces a radish-like root. The root of maca is typically dried and stored, and will easily keep for seven years. The plant is cultivated in the Junin plateau of Peru's Central Highlands, and was highly revered by the Inca.

Tribal and Medicinal Uses
To the Andean Indians and indigenous peoples, maca is a valuable commodity. Because so little else grows in the region, maca is often traded with communities at lower elevations for such other staples as rice, corn, green vegetables, and beans. The dried roots can be stored for up to seven years. Native Peruvians traditionally have utilized maca since pre-Incan times for both nutritional and medicinal purposes. It is an important staple in the diets of these people, as it has the highest nutritional value of any food crop grown there. It is rich in sugars, protein, starches, and essential nutrients (especially iodine and iron). The tuber or root is consumed fresh or dried. The fresh roots are considered a treat and are baked or roasted in ashes (in the same manner as sweet potatoes). The dried roots are stored and, later, boiled in water or milk to make a porridge. They also are made into a popular sweet, fragrant, fermented drink called maca chicha. In Peru even maca jam, pudding, and sodas are popular. The tuberous roots have a tangy, sweet taste and an aroma similar to that of butterscotch.

This energizing plant is also referred to as Peruvian ginseng (although maca is not in the same family as ginseng). Maca has been used for centuries in the Andes to enhance fertility in humans and animals. Soon after the Spanish conquest in South America, the Spanish found that their livestock was reproducing poorly in the highlands. The local Indians recommended feeding the animals maca; so remarkable were the results that Spanish chroniclers gave in-depth reports. Even colonial records of some 200 years ago indicate that payment of (roughly) nine tons of maca was demanded from one Andean area alone for this purpose.

In Peruvian herbal medicine today, maca is reported to be used as an immunostimulant; for anemia, tuberculosis, menstrual disorders, menopause symptoms, stomach cancer, sterility (and other reproductive and sexual disorders); and to enhance memory. Maca has been growing in world popularity over the last several years due to several large U.S. marketing campaigns touting its energizing, fertility enhancement, hormonal balancing, aphrodisiac, and, especially, enhanced sexual performance properties. Other (anecdotal) herbal medicine uses in the U.S. and abroad include increasing energy, stamina, and endurance in athletes, promoting mental clarity, combating male impotence, and helping with menstrual irregularities, female hormonal imbalances, menopause, and chronic fatigue syndrome.

During the height of the Incan empire, legend has it that Incan warriors would consume maca before entering into battle. This would make them fiercely strong. But after conquering a city the Incan soldiers were prohibited from using maca, to protect the conquered women from their powerful sexual impulses. Thus as far back as 500 years ago, maca's reputation for enhancing strength, libido and fertility was already well established in Peru.

Today, maca's popularity is very much on the increase, as people discover that the plant really does boost libido, sexual function and overall energy. Acreage in Peru dedicated to Maca cultivation is increasing every year to meet demand, and a number of scientists have turned their attention to the properties of the root. In Peru, maca is used by men and by women who want to put more fire into their sex lives. And in the U.S., Europe and Japan, dietary supplements containing maca are gaining ardent devotees.

Maca Nutrition
What natural ingredients in maca promote its reputed sex-enhancing effects? In-depth analysis of maca conducted in 1998 by Dr. Qun Yi Zheng and his colleagues at PureWorld Botanicals shows that maca contains about 10 percent protein, almost 60 percent carbohydrate, and an assortment of fatty acids. These ingredients are common and nothing special. But the investigators also discovered two groups of novel compounds, the macamides and the macaenes. These agents are believed to be directly responsible for maca's sex-boosting powers.
