Maca originated in Peru, and now Yunnan is imported from Peru. It grows in the high mountain area of the Peruvian Andes above 4000 meters above sea level and looks like a radish. The best maca is the one with a small head and deep color. Maca is called Peruvian ginseng, as the name implies, because it is rich in nutrients, especially various rare trace elements, which are very beneficial to human health. As for domestic advertisements, it is too exaggerated to focus only on the selling point of aphrodisiac, which really makes Maca one-sided.
