About this Course
How did the human mind leap from primate cognition to complex symbolic language and self‑awareness? This course revisits Terence McKenna’s Food of the Gods and brings the Stoned Ape Hypothesis into the 21st century by integrating contemporary mycology, paleontology, neuro‑ecology, epigenetics, and evolutionary genetics. Students survey Psilocybe ecology with a visual overview of its molecular identity, fungal phylogeny, and documented examples of host‑altering strategies.
Case studies examine fungal behavioral manipulation – Cordyceps (notably Ophiocordyceps and the “zombie ant” phenomenon) – to illustrate how fungal chemistry can alter animal nervous systems and promote spore dispersal. The syllabus evaluates ecological scenarios for early hominid exposure to psychoactive fungi and tests proposed mechanisms – neuroplasticity, synesthesia, epigenetic regulation, and horizontal gene transfer – that could plausibly mediate short‑ and long‑term biological effects relevant to cognition. Students will learn to evaluate psilocybin’s ecological and neurobiological significance and to distinguish testable biological models from historical speculation. Note: ethical, legal, and safety considerations are integral to the curriculum; no instruction on illegal activity or cultivation will be provided.
What You will learn
- Understand the botanical and chemical properties of psilocybin and its proposed evolutionary function as an eco‑neuro‑hormone.
- Analyze the fossil record and genetic history of fungi to interpret fungal survival strategies and deep phylogeny.
- Evaluate mechanisms of horizontal gene transfer and epigenetic regulation as potential drivers of rapid evolutionary change.
- Critically assess the Stoned Ape Hypothesis using modern neuroscience, including neuroplasticity, synesthesia, and neocortical reorganization.
- Trace plausible ecological and behavioral pathways for early hominid exposure to psychoactive fungi and their cultural consequences.
- Synthesize interdisciplinary evidence to distinguish testable biological mechanisms from historical or speculative claims.

About this Course
For nearly a century, the world has viewed the Coca leaf through a single, narrow lens: the white powder derived from it. But the story of Erythroxylum is far older, deeper, and more complex than the stigma suggests.
Reclaiming the Divine Coca Leaf: Science, Spirit, and Stigma is an eye-opening course that separates the sacred plant from the illicit chemical. This journey takes you behind the headlines and the War on Drugs to reveal an 8,000-year-old relationship between humanity and the Andes’ most revered botanical treasure.
We will deconstruct the “Great Confusion”—the historical errors and scientific misunderstandings that conflated a nutrient-dense superfood with a dangerous narcotic. From the ancient rituals of the Incas to the distinct taxonomy of the plant, and finally to groundbreaking modern research in botanical medicine, you will learn why Indigenous cultures call it “The Divine Plant.”
What You will learn
- The Truth About the Plant, Distinguish the Coca leaf from cocaine. Learn the chemistry, nutritional profile, and why the leaf is a mild stimulant closer to tea or coffee than hard drugs.
- Andean History & Ritual: Explore the “Real Story” of the Andes, where Coca is the social fabric of the community, used in Kintu offerings, weddings, and as a sacred link to the Pachamama (Earth Mother).
- Correcting History: Uncover how early commercialization (like Vin Mariani) and scientific errors (like those of Sigmund Freud) distorted the global perception of the leaf.
- Ethnobotany & Biodiversity: Study the fascinating evolution and taxonomy of the plant, including the unique varieties found across Peru, Bolivia, and Colombia.
- A New Medical Era: Look forward to the future of Magdalena Biosciences and the development of legal, FDA-approved botanical medicines for mental health and metabolic disorders.

About this Course
“Drugs don’t grow on trees”—or do they? In the lush basins of the Amazon rainforest stands Croton lechleri, a pioneer tree species known to Indigenous peoples for centuries as Sangre de Grado (Dragon’s Blood) for its thick, red latex. This course offers a rare, behind-the-scenes look at the journey of this sacred plant from the rainforest floor to the modern pharmacy shelf as Crofelemer—the first oral botanical drug ever approved by the US FDA.
This curriculum bridges the gap between traditional ecological knowledge and cutting-edge pharmacology. You will explore the “Two Scientists” model, which recognizes that the Indigenous healer and the Western physician possess equal but distinct forms of expertise. We will trace the development of Crofelemer, examining how a complex botanical molecule regulates physiology without entering the bloodstream.
Beyond the chemistry, this course is a deep dive into sustainable supply chains and social responsibility. You will learn how a pharmaceutical product can drive reforestation, support local economies, and honor the intellectual property of Indigenous communities. From the logistics of latex extraction in Peru to the rigorous quality control required by the FDA, this is a masterclass in how to bring a plant-based medicine to the world ethically, sustainably, and effectively.
