Peruvian ginseng-Maca

Maca herb (Lepidium meyenii) is a root-like vegetable shaped like a radish. It is also called Peruvian Ginseng. Most botanists now consider the widely cultivated Maca of today to be a newer domesticated species: Lepidium peruvianum. The Maca is related to the radish and the turnip, and this shows in the growth habit, size, and proportions of the root.

The main active constituents in Maca root are the amino acids phenylalanine, tyrosine, histidine, arginine and a chemical called p-methoxybenzyl isothiocyanate, which has reputed aphrodisiac properties.

Introduction

Maca herb grows high in the harsh climate of the Andes Mountains in South America at elevations up to 15,000 feet. It is one of the few plants that can be cultivated here. For more than two millennia, native Peruvians have used Maca root as food and salutary herb, to promote endurance and improve energy, vitality, sexual virility and fertility.

Applications

From the Maca plant it is mainly the roots that are used. These roots are highly nutritious with about 11% protein content. When Maca is harvested, the roots are traditionally dried by exposing them to sunlight for 4-6 days. After they have been dried, they can be stored in cool, dark places for several years. For consumption, the dried roots are rehydrated by boiling them in water until they are soft. They can also be baked, roasted, prepared as a porridge, and have been used for making a fermented drink. The fresh roots are considered a treat and are baked or roasted in ashes (in the same manner as sweet potatoes).
