The search for a cure for cancer this time takes the famous fungotherapist Irina Filippova and her team of fellow enthusiasts to the mysterious distant country of Peru. There they become acquainted with a local miracle, a “gift of the gods” to the ancient Indians - black corn, practically unknown outside its homeland, unlike its golden sister. Such an unknown, as travelers find out, is a huge omission, because if yellow corn was given to the indigenous people of Peru for food, then black corn was given for healing. With its help, the ancestors of modern Peruvians treated most known diseases and from it they obtained penicillin much earlier than it was discovered by Europeans. Black corn is a huge step towards a panacea for cancer; in addition, it eliminates excess weight, significantly reduces the risk of atherosclerosis, normalizes blood pressure and blood sugar, and it is also used to make an amazing energy drink, which far surpasses any known to us in its properties. There are other medicinal plants in Peru, and not only the plants that will be touched upon in the story. Traveler Ingvar Korotkov will tell you about this and the customs of Peru, which amaze tourists, in his notes.
