The World Natural Heritage of forests includes almost a third of the whole UNESCO properties, including primary territories, Reserves of biodiversity and specific conservation areas, with four Intangible Heritage of the Amazon. Forests, however, represent since millennia complex landscapes, cogenerated by woods and animal communities. Humans evolved in such a dynamic system, expressing natural and cultural solutions for food, medicines, products and means of organization. A living value in itself, a forest is ancestrally observed as an organizational model of interconnection of different plants and living beings, shaping a complex habitat and unique food chains. The biospheres of a forest, embedding an Ethnosphere and its consequent Noosphere, are here proposed as an Immaterial Heritage. The wood organization complexity is read as Intangible Heritage in the knowledge it entails for the generation of wellness throughout the history of the planet. The research compares ethnomedical evidences between Forest coding in the Camaldolese woods of Italy, Nordic pharmacopeia in Finland, Ashaninka Ethnomedicine at Mayantuyacu in the Peruvian Amazon and Muchik ancestral healing in northern Peru.
