“Like the burning of the ancient library at Alexandria or the supremely ignorant incineration of stacks of invaluable Mayan codices, the loss of knowledge we are experiencing as the last of the traditional elders pass from this physical plane of existence without heirs to their knowledge- as well as the very environment in which sacred plants grow- is a tragedy occurring right now as you read these lines, one that could well be beyond redemption.”

“If science is defined or understood as a mode of seeking knowledge, a means of interpreting nature in a way that can be demonstrated to others, then the plant-medicine traditions of the Amazon as they have been practiced constitute an authentic scientific discipline.”

“When speaking of the mighty Andes and the so-called "eyebrows" country at the range's eastern base- the Tropical Wet Forest region-I am first obliged to give homage to the Apu, the Mountain Lords, the ice-capped everlasting sovereigns of these great lands, on whose forested slopes manifests the most marvelous biological diversity.”

“REVIEW: Like a master artisan, Weisberger weaves together threads of anthropology, botany, ecology and psychology in an inspiring tapestry of ideas sure to keep discerning readers warm and hopeful in these cold and desolate times.Unlike other texts, which ordinarily prescribe structural (ie. social, political, economic) solutions to the global crisis of environmental destruction, Rainforest Medicine hones in on the root cause of Western schizophrenia: spiritual poverty, and the resultant alienation of the individual from his environment. This incisive perception is married to a message of hope: that the keys to the door leading to promising new human vistas are held in the humblest of hands; those of the spiritual masters of the Amazon and the traditional cultures from which they hail. By illumining the ancient practices of authentic indigenous Amazonian shamanism, Weisberger supplies us with a manual for conservation of both the rainforest and the soul. And frankly, it could not have arrived at a better time.”

“Among the Secoya, clear guidelines regulate preparation of the medicine. They are adamant about this preparation method and insist that the guidelines be followed. I've already discussed some fundamentals of harvesting the plants. When respected, all the elements and subtle factors combine to make a potent and efficacious medicine, necessary for a positive and healing ceremony.”

“The Secoya are trapped between the devastating effects of the colonization frontier and their rich traditional past, which is proving to be as fragile a reality and as fleeting a memory as the most powerful visions of their esoteric science. But instead of detailing that sad scene, in this chapter I have attempted to portray my image of this culture as I see it in its fading colors, magic, and awe-inspiring mystery.”

“Like the burning of the ancient library at Alexandria or the supremely ignorant incineration of stacks of invaluable Mayan codices, the loss of knowledge we are experiencing as the last of the traditional elders pass from this physical plane of existence without heirs to their knowledge- as well as the very environment in which sacred plants grow- is a tragedy occurring right now as you read these lines, one that could well be beyond redemption.”

“The Waorani carry out a similar diet with their arrow poison, called curare or, in their language, oomae. This is another amazing product of the indigenous science, a most sophisticated technology that the Waorani extrapolated from an ancient myth.”

“Before my first visit to Waorani territory, I was introduced to don Casimiro Mamallacta, a traditional Kichwa healer and family man living in the outskirts of the jungle town of Archidona, by his daughter Mercedes, whom I met at the Jatun Sacha biological station. During the years that I was collaborating on the demarcation effort and in between the work sessions, I lived with don Casimiro's family.”
