Information 

Maca root powder is made of maca root.
Maca root, also known as Lepidium meyenii, is a plain, very resistant plant of the family Cruciferae, reddish roots like radishes.

Over time, the Inca legend says the Inca warriors were taking these plants before battles, which would give them enormous power but after winning the battle would not take it due to the strong effect on sex drive.
Thus, even before 5000 years, benefits of maca powder have already had a reputation for strong force, libido, and that they were good for increasing fertility. Maca root powder is now more popular because of its beneficial aphrodisiac properties and generally strengthening of the body.
Oral administration of Lepidium meyenii extract enhanced the sexual function of the mice and rats, as evidenced by an increase in the number of complete intromissions and the
the number of sperm-positive females in normal mice.
