Nurtured. Honest. Empowered.



Maca is an indigenous Andean plant that belongs to the brassica (mustard) family. Maca is a vegetable that has been cultivated as a root crop for at least 2,000 years and used both nutritionally and medicinally. It can be found wild in Peru, Bolivia, Paraguay, and Argentina, but has primarily been cultivated in the highlands of the Peruvian Andes. According to folk belief, Maca is an aphrodisiac and enhances sexual drive in humans and domestic animals, which tends to be reduced at higher altitudes.


Maca is known as an adaptogen, broadly contributing to overall well being and a healthy mood. Additionally, maca root has been touted to normalize energy levels and endurance and support a healthy libido.
