Maca or "Peruvian ginseng", is a rather rare plant native to the Andes that grew exclusively on an altiplano close to Lake Junin. This plant was primarily used in cooking but its root is used nowadays to tonify the body.

It is known that the root of Maca strengthens the immune system and restores a upsurge of physical and mental energy. Besides its fortifying properties, it works efficiently on the sexual disorders and on the unbalanced hormones. So, Maca enhances fertility, improves physical performance and alleviates the symptoms of the menopause.
