Maca Root 

The maca root is a perennial low-growing herb that is found in the Andes region. The root is usually pear-like and around three inches in diameter. It can thrive in mountainous conditions where it is commonly quite sunny, windy or below-freezing. The plant is self-fertilizing and is capable of growing in areas where it is quite rocky and the soil is poor, containing little of the nutrients other plants would need to thrive. Because of this it can easily be stored for long periods of time after it is picked without losing its essential nutrition.

Maca roots contain high amounts of minerals including iron and protein as well as high amounts of fiber, contributing to its frequent medicinal use. Many cultures in the Andes region rely in the maca root as part of their diet. It is believed that this root contains healing powers that can help to address conditions such as low energy, low stamina, fertility issues, limited endurance, tuberculosis or discomfort from the menstrual cycle.
