Imagine a plant, a plain tuber, that looks like a radish, that grows at an altitude of 4000 meters, that survives extreme heat, cold, severe weather, and a thin atmosphere, and that at the same time stores strength, vitamins, trace elements, and mineral nutrients. The Inkas had already used maca root from the Andean highlands as food and medicine. Peter Carl Simons, a health expert, shows how this unremarkable plant can still be used as part of therapy. The field of application includes cancer therapy, erectile dysfunction, depression, premature birth, female fertility, anemia, an endocrine disorder, and many others. The maca root is also known in the context of anti-aging therapy.
