Imagine a plant, a plain tuber, that looks like a radish, that grows at an altitude of 4000 metres, that survives extreme heat, cold, severe weather and a thin atmosphere and which at the same time stores strength, vitamines, trace elements and mineral nutrients.

The Inkas had already used maca root from the Andean high plateaus as food and as medicine. Peter Carl Simons, a health expert, shows how this unremarkable plant can still be used as part of a therapy.

The field of application includes: cancer therapy, erectile dysfunction, depression, premature birth and female fertility, anaemia, endocrine disorder, and many other. The maca root is also known in the context of anti-aging therapy.
