In kichwa, Mamallacta means mother hearth; never a surname had been more appropriate for a family that lives around a patriarch curandero bearer of an ancestral knowledge. He is like a man from another world, who speaks little Spanish and interpretes the visions that his patients have under the Ayawaska effects, almost as a Freudian psychologist interpreting dreams. The sons, especially Nelson and Elias, are greatly included in the XXI century and blindly defeds the cause of protecting nature and the autochthonous culture. The Mamallacta property, in an idyllic position near Archidona, in the Napo province, ecuadorian central Amazon, is a bothanic garden with medical herbs, Nelson is part of the "net of the seeds guardians" an au pair exchange between owners of specimen and varieties which are threatened with extinction, seeding them in their own garden, means stopping their extinction; Iji the other brother, has a nursery for amazonic plants protection and the supply where they are disappearing. All this is surrounded by the volunteer's visits, international contacts, Ayawaska ceremonies and a good familiar feeling of that big clan of natives called Mamallacta.
