Imagine walking through a dense rainforest with an indigenous elder who can identify hundreds of plants by sight, smell, and touch—knowing precisely which leaf can cure a fever, which root can ease pain, and which bark can purify water. This profound relationship between people and plants lies at the heart of ethnobotany, a fascinating interdisciplinary field that studies how human cultures interact with, use, and understand the botanical world around them.

Ethnobotany is more than just cataloging plant uses. It represents a bridge between diverse knowledge systems—connecting traditional wisdom accumulated over millennia with modern scientific inquiry. As we face unprecedented global challenges including climate change, biodiversity loss, and health crises, ethnobotany offers invaluable insights that could help shape sustainable solutions for our shared future.

What is Ethnobotany?

The term “ethnobotany” combines two Greek roots: ethno (meaning “people” or “culture”) and botany (the study of plants). In its simplest definition, ethnobotany is the scientific study of the relationships between plants and people, examining how different cultures use, manage, and perceive the botanical world.

American botanist John William Harshberger coined the term in 1895 during a lecture at the University of Pennsylvania, defining it as the study of “plants used by primitive and aboriginal people.” His definition aimed to clarify “the cultural position of the tribes who used the plants for food, shelter or clothing.”

However, modern ethnobotany has evolved far beyond Harshberger’s original conception. Today’s ethnobotanists recognize that all societies—not just indigenous or traditional ones—maintain complex relationships with plants. Contemporary definitions emphasize the dynamic, reciprocal nature of plant-human interactions across all cultures and time periods.

Richard Evans Schultes, widely regarded as the “father of modern ethnobotany,” provided a more comprehensive definition:

“Ethnobotany simply means investigating plants used by primitive societies in various parts of the world… [It comprises] the complete registration of the uses of and concepts about plant life in primitive societies, comprising aspects of botany, anthropology, archeology, plant chemistry, pharmacology, history, geography, and sundry other tangential fields of the sciences and arts.”

This expansive view captures the truly interdisciplinary nature of ethnobotany, which draws on botany, anthropology, ecology, chemistry, medicine, linguistics, and even mythology to create a holistic understanding of human-plant relationships.

The Scope of Ethnobotanical Research

Ethnobotanists investigate numerous aspects of plant-human interactions, including:

Food and Agriculture: How cultures cultivate, harvest, prepare, and consume plants; development of crop varieties; traditional farming practices.

Medicine and Healing: Traditional medicinal uses of plants; preparation methods; spiritual and ritual dimensions of healing.

Material Culture: Use of plants for shelter, clothing, tools, dyes, and other technologies.

Spiritual and Ceremonial Uses: Sacred plants in religious rituals, shamanic practices, and cultural ceremonies.

Ecological Knowledge: Traditional understanding of plant ecology, seasonal patterns, and environmental relationships.

Conservation: Indigenous resource management practices that maintain biodiversity.

Cultural Identity: How plant knowledge shapes cultural worldviews, languages, and community identity.

Historical Roots: A Journey Through Time

While Harshberger coined the term “ethnobotany” in the late 19th century, the practice of documenting plant-human relationships extends back thousands of years.

Ancient Beginnings (1st Century – Medieval Period)

The earliest recognizable ethnobotanical work emerged in ancient civilizations. Pedanius Dioscorides (40-90 AD), a Greek physician serving in the Roman army, authored De Materia Medica, an extensive botanical text describing the medicinal and culinary properties of over 600 Mediterranean plants. Dioscorides traveled extensively throughout the Roman Empire—including Greece, Crete, Egypt, and Petra—documenting local plant uses and building one of the most comprehensive pharmacological texts of the ancient world. His work remained influential for over 1,500 years.

During the medieval period, ethnobotanical knowledge was preserved primarily in monastery gardens and Islamic centers of learning. Monks cultivated physic gardens (medicinal plant gardens) attached to hospitals and religious buildings, maintaining practical botanical knowledge for culinary and medical purposes, though they did not approach it with modern anthropological perspectives.

Age of Enlightenment and Exploration (18th-19th Centuries)

The Age of Enlightenment brought systematic scientific approaches to botanical exploration. In 1732, Carl Linnaeus, the father of modern taxonomy, conducted research expeditions in Scandinavia, interviewing the Sami people about their ethnological uses of plants—an early example of systematic ethnobotanical inquiry.

The 18th and 19th centuries witnessed unprecedented botanical exploration driven by colonial expansion and economic interests. Explorers like Alexander von Humboldt collected extensive data from the New World, while James Cook’s Pacific voyages brought back remarkable collections and information about Pacific Island flora. Major botanical gardens, including the Royal Botanic Gardens at Kew (established 1759), were founded during this period, sending out gardener-botanist explorers to collect and document plants worldwide.

The discovery of the Americas dramatically expanded European botanical knowledge through ethnobotany. Crops such as potatoes, peanuts, avocados, tomatoes, corn, and chocolate—all unknown in Europe—were documented through studying indigenous agricultural practices. French explorer Jacques Cartier famously learned a cure for scurvy (a tea made from coniferous tree needles, likely spruce) from an Iroquois tribe, demonstrating the practical value of indigenous botanical knowledge.

Edward Palmer (1831-1911), often called the “father of ethnobotany,” laid crucial groundwork for modern ethnobotanical research. From the 1860s to 1890s, Palmer collected material culture artifacts and botanical specimens from indigenous peoples in the North American Great Basin and Mexico. His extensive collections and detailed documentation of traditional plant uses established methodological standards for the emerging field.

Early 20th Century: Formalization of the Field

Though initial efforts suffered from inadequate collaboration between botanists and anthropologists. Botanists focused on species identification and plant uses without understanding cultural contexts, while anthropologists examined cultural roles of plants but treated botanical details superficially.

Leopold Glück, a German physician working in Sarajevo in the late 19th century, conducted groundbreaking work that is now recognized as the first modern ethnobotanical study. His 1896 publication documented traditional medicinal uses of plants by rural Bosnian people from an emic perspective—that is, from the viewpoint of the people themselves rather than imposing external categories.

Notable early ethnobotanists who advanced the field through improved interdisciplinary collaboration included:

• Matilda Coxe Stevenson – documented Zuni plants (1915)
• Frank Cushing – studied Zuni foods (1920)
• Wilfred Robbins, John Peabody Harrington, and Barbara Freire-Marreco – collaborative team approach studying Tewa pueblo plants (1916)
• Paul Weatherwax (1888-1958) – studied the morphology, evolution, and ethnobotany of maize, publishing influential works on corn’s origins

The Schultes Era: Modern Ethnobotany Takes Shape (Mid-20th Century)

Richard Evans Schultes (1915-2001) transformed ethnobotany from a documentation exercise into a respected scientific discipline combining rigorous botanical research with deep cultural immersion and respect for indigenous knowledge.

Born in East Boston to a plumber’s family, Schultes entered Harvard University in 1933 intending to study medicine. However, a biology course called “Plants and Human Affairs,” taught by orchidologist Oakes Ames, changed his trajectory. For his undergraduate thesis, Schultes studied the ritual use of peyote cactus among the Kiowa people of Oklahoma—one of the first field investigations of peyote as a healing sacrament.

Schultes spent nearly 14 years living in the Amazon rainforest, primarily during the 1940s and 1950s. Unlike many Western scientists of his era, he approached his work with profound respect for indigenous knowledge, living among native communities, eating local foods, and participating in rituals. His willingness to experience traditional medicines firsthand—including various hallucinogenic plants—demonstrated his understanding that plants held not just chemical but spiritual significance.

His extensive fieldwork resulted in:

• Documentation of thousands of plant species and their traditional uses
• Collection of over 30,000 plant specimens
• Identification of numerous previously unknown medicinal plants
• Advocacy for conservation of both rainforest habitats and indigenous knowledge
• Training of a generation of influential ethnobotanists

Schultes’ landmark book The Plants of the Gods: Their Sacred, Healing, and Hallucinogenic Powers (1979), co-authored with chemist Albert Hofmann (discoverer of LSD), remains continuously in print and represents one of ethnobotany’s most influential popular works.

Expanding Global Perspectives (Late 20th Century)

As ethnobotany matured globally, pioneering researchers in various regions established regional traditions and methodologies.

Dr. Sudhanshu Kumar Jain (1926-2021), known as the “Father of Indian Ethnobotany,” revolutionized ethnobotanical research in South Asia. Working at the Botanical Survey of India and the National Botanical Research Institute in Lucknow, Dr. Jain:

• Created the first Ethnobotanical Section at the Central Botanical Laboratory in 1960.
• Founded the Society of Ethnobotanists in 1980.
• Established the Institute of Ethnobiology in 1995.
• Documented under-exploited uses of approximately 2,000 plant species.
• Published the influential Dictionary of Indian Folk Medicine and Ethnobotany (1991), which was used as evidence in U.S. courts to help India win the famous Turmeric Patent case.

Dr. E.K. Janaki Ammal (1897-1984), an earlier Indian pioneer, created the Ethnobotanical Section at the Central Botanical Laboratory and emphasized the importance of indigenous knowledge in drug discovery, envisioning “healing principles of our new plant wealth” being made available globally.

Barbara McClintock (1902-1992), though primarily known for her Nobel Prize-winning genetics research on “jumping genes,” made significant contributions to ethnobotany. Beginning in 1957, she received funding to study indigenous maize strains in Central and South America, exploring chromosomal, morphological, and evolutionary characteristics of various maize races. Her seminal work The Chromosomal Constitution of Races of Maize left lasting impacts on paleobotany, ethnobotany, and evolutionary biology.

Contemporary Voices (Late 20th Century – Present)

Recent decades have seen ethnobotany evolve into an increasingly diverse, ethically conscious, and globally relevant discipline.

Wade Davis (born 1953), a Canadian anthropologist and ethnobotanist who studied under Schultes at Harvard, expanded ethnobotany’s scope beyond plants to encompass broader cultural and ecological concerns. He coined the term “ethnosphere”—the sum total of all thoughts, dreams, ideas, and beliefs brought into being by human imagination—to highlight the parallel loss of cultural and biological diversity. Davis’ work emphasizes the interconnection between cultural survival and environmental conservation.

Gary Paul Nabhan (born 1952), considered a pioneer of the local food movement and heirloom seed saving movement, has focused on plant-human relationships in desert environments, particularly working with indigenous communities along the U.S.-Mexico border. He co-founded Native Seeds/SEARCH, a nonprofit dedicated to preserving indigenous southwestern agricultural plants and traditional knowledge. His work demonstrates how traditional agricultural practices can inform modern sustainable food systems.

Michael J. Balick, Vice President for Botanical Science at the New York Botanical Garden, has spent over four decades studying plant-people relationships in tropical environments including Belize, Micronesia, and Melanesia. His work emphasizes ethical partnerships with indigenous communities, ensuring that research benefits are shared equitably and that local knowledge rights are protected.
