Ethnobotany is the scientific study of the relationships between people and plants, examining how different cultures use, manage, and perceive plant species across time and geography. The field sits at the intersection of botany, anthropology, ecology, and pharmacology, drawing on methods from both the natural and social sciences. Ethnobotanists investigate how indigenous and local communities classify plants, incorporate them into food systems, deploy them as medicines, use them in rituals and ceremonies, and weave them into shelter, clothing, and tools.
The discipline traces its formal origins to the late nineteenth century, when the American botanist John W. Harshberger coined the term in 1896, though humans have recorded plant knowledge for millennia in texts such as the Egyptian Ebers Papyrus and the Chinese Shennong Ben Cao Jing. In the twentieth century, Richard Evans Schultes, often called the father of modern ethnobotany, conducted pioneering fieldwork in the Amazon basin that revealed the depth of indigenous botanical knowledge and led directly to the discovery of numerous bioactive compounds. His student Wade Davis continued this tradition, bringing ethnobotanical insights to a global audience.
Today, ethnobotany is more relevant than ever as biodiversity loss, climate change, and cultural erosion threaten both plant species and the traditional knowledge systems that have sustained human communities for generations. Modern ethnobotanists work alongside indigenous communities as partners, applying principles of prior informed consent and benefit-sharing under frameworks such as the Nagoya Protocol. The field contributes to drug discovery, sustainable agriculture, conservation biology, and food security, making it a critical bridge between traditional ecological knowledge and contemporary science.
One step at a time.
A cumulative body of knowledge, practices, and beliefs about the relationships between living beings and their environment, evolving through adaptive processes and handed down through generations by cultural transmission.
Example: Aboriginal Australians use fire-stick farming knowledge passed down over tens of thousands of years to manage landscapes and promote the growth of food plants like yams and bush tomatoes.
The systematic search for useful chemical compounds, genes, or organisms in nature, often guided by ethnobotanical knowledge of how indigenous peoples use local plants for medicinal or other purposes.
Example: The anti-cancer drug vincristine was developed from the rosy periwinkle (Catharanthus roseus), a plant long used in traditional medicine in Madagascar.
The interdisciplinary study of biologically active substances used or observed by traditional cultures, bridging indigenous medicinal knowledge with modern pharmacological science to identify new drug candidates.
Example: The isolation of artemisinin from sweet wormwood (Artemisia annua), used in traditional Chinese medicine for over 2,000 years to treat fevers, led to a breakthrough malaria treatment and a Nobel Prize for Tu Youyou.
The appropriation of traditional knowledge and biological resources from indigenous peoples or developing countries without adequate consent, compensation, or recognition of the source community's intellectual contributions.
Example: The patenting of neem (Azadirachta indica) extracts by Western corporations was contested by India because neem's pesticidal and medicinal properties had been documented in Indian traditional knowledge for centuries.
An international agreement supplementary to the Convention on Biological Diversity that establishes a legal framework for the fair and equitable sharing of benefits arising from the utilization of genetic resources and associated traditional knowledge.
Example: Under the Nagoya Protocol, a pharmaceutical company seeking to develop a drug from a plant used in Peruvian traditional medicine must negotiate access and benefit-sharing agreements with the relevant indigenous communities and government.
Statistical and analytical techniques used to measure the cultural importance of plants, including indices such as the Use Value index, Informant Consensus Factor, and Cultural Importance Index that allow comparison across communities and regions.
Example: Researchers calculating the Use Value of moringa (Moringa oleifera) in a West African community might interview 50 informants and find it mentioned for food, medicine, water purification, and fodder, yielding a high UV score.
The multigenerational process by which humans selectively breed wild plant species to enhance desired traits such as larger fruit size, reduced toxicity, or higher yield, fundamentally altering plant genetics and morphology.
Example: Teosinte, a wild grass with tiny hard kernels native to Mexico, was domesticated by Mesoamerican peoples over thousands of years into modern maize (corn), one of the world's most important food crops.
Forest patches protected by local communities on religious or spiritual grounds, serving as important reservoirs of biodiversity and living examples of how cultural beliefs can drive effective conservation practices.
Example: In the Western Ghats of India, thousands of sacred groves (Devarakadus) protected by Hindu communities have preserved old-growth forest fragments with species that have disappeared from surrounding areas.
