Ethnobotany is the study of a region's plants and their practical uses through the traditional knowledge of a local culture and people. [1] An ethnobotanist thus strives to document the local customs involving the practical uses of local flora for many aspects of life, such as plants as medicines, foods, and clothing. [2] Richard Evans Schultes, often referred to as the "father of ethnobotany", [3] explained the discipline in this way:

Richard Evans Schultes American ethnobotanist

Richard Evans Schultes was an American biologist. He may be considered the father of modern ethnobotany. He is known for his studies of the uses of plants by indigenous peoples, especially the indigenous peoples of the Americas. He worked on entheogenic or hallucinogenic plants, particularly in Mexico and the Amazon, involving lifelong collaborations with chemists. He had charismatic influence as an educator at Harvard University; several of his students and colleagues went on to write popular books and assume influential positions in museums, botanical gardens, and popular culture.


Ethnobotany simply means ... investigating plants used by societies in various parts of the world. [4]

Since the time of Schultes, the field of ethnobotany has grown from simply acquiring ethnobotanical knowledge to that of applying it to a modern society, primarily in the form of pharmaceuticals. [5] Intellectual property rights and benefit-sharing arrangements are important issues in ethnobotany. [6]

Intellectual property (IP) is a category of property that includes intangible creations of the human intellect. Intellectual property encompasses two types of rights; industrial property rights and copyright. It was not until the 19th century that the term "intellectual property" began to be used, and not until the late 20th century that it became commonplace in the majority of the world.

The idea of ethnobotany was first proposed by the early 20th century botanist John William Harshberger. [7] While Harshberger did perform ethnobotanical research extensively, including in areas such as North Africa, Mexico, Scandinavia, and Pennsylvania, [7] it was not until Richard Evans Schultes began his trips into the Amazon that ethnobotany become a more well known science. [8] However, the practice of ethnobotany is thought to have much earlier origins in the first century AD when a Greek physician by the name of Pedanius Dioscorides wrote an extensive botanical text detailing the medical and culinary properties of "over 600 mediterranean plants" named De Materia Medica. [2] Historians note that Dioscorides wrote about traveling often throughout the Roman empire, including regions such as "Greece, Crete, Egypt, and Petra", [9] and in doing so obtained substantial knowledge about the local plants and their useful properties. European botanical knowledge drastically expanded once the New World was discovered due to ethnobotany. This expansion in knowledge can be primarily attributed to the substantial influx of new plants from the Americas, including crops such as potatoes, peanuts, avocados, and tomatoes. [10] One French explorer in the 16th century, Jacques Cartier, learned a cure for scurvy (a tea made from boiling the bark of the Sitka Spruce) from a local Iroquois tribe. [11]

John William Harshberger American botanist

John William Harshberger, was an American botanist who specialized in plant geography, ecology and plant pathology. He taught at the University of Pennsylvania for more than 35 years. He was an ardent plant conservationist and he is credited with coining the term "ethnobotany".

Pedanius Dioscorides Greco-Roman physician and pharmacologist

Pedanius Dioscorides was a Greek physician, pharmacologist, botanist, and author of De Materia Medica —a 5-volume Greek encyclopedia about herbal medicine and related medicinal substances, that was widely read for more than 1,500 years. He was employed as a physician in the Roman army.

<i>De Materia Medica</i> encyclopaedia and pharmacopoeia of herbs

De Materia Medica is a pharmacopoeia of medicinal plants and the medicines that can be obtained from them. The five-volume work was written between 50 and 70 CE by Pedanius Dioscorides, a Greek physician in the Roman army. It was widely read for more than 1,500 years until supplanted by revised herbals in the Renaissance, making it one of the longest-lasting of all natural history books.

Medieval and Renaissance

During the medieval period, ethnobotanical studies were commonly found connected with monasticism. Notable at this time was Hildegard von Bingen. However, most botanical knowledge was kept in gardens such as physic gardens attached to hospitals and religious buildings. It was thought of in practical use terms for culinary and medical purposes and the ethnographic element was not studied as a modern anthropologist might approach ethnobotany today.[ citation needed ]

Hildegard of Bingen Medieval saint, prophetise, mystic and Doctor of Church

Hildegard of Bingen, also known as Saint Hildegard and Sibyl of the Rhine, was a German Benedictine abbess, writer, composer, philosopher, Christian mystic, visionary, and polymath. She is considered to be the founder of scientific natural history in Germany.

Physic garden

A physic garden is a type of herb garden with medicinal plants. Botanical gardens developed from them.

An anthropologist is a person engaged in the practice of anthropology. Anthropology is the study of aspects of humans within past and present societies. Social anthropology, cultural anthropology, and philosophical anthropology study the norms and values of societies. Linguistic anthropology studies how language affects social life, while economic anthropology studies human economic behavior. Biological (physical), forensic, and medical anthropology study the biological development of humans, the application of biological anthropology in a legal setting, and the study of diseases and their impacts on humans over time, respectively.

Age of Reason

Carl Linnaeus carried out in 1732 a research expedition in Scandinavia asking the Sami people about their ethnological usage of plants. [12]

The Expedition to Lapland, the northernmost region in Sweden, by Carl Linnaeus in 1732 was an important part of his scientific career.

Ethnology social science that deals with ethnies (Peoples)

Ethnology is the branch of anthropology that compares and analyzes the characteristics of different peoples and the relationships between them.

The age of enlightenment saw a rise in economic botanical exploration. Alexander von Humboldt collected data from the New World, and James Cook's voyages brought back collections and information on plants from the South Pacific. At this time major botanical gardens were started, for instance the Royal Botanic Gardens, Kew in 1759. The directors of the gardens sent out gardener-botanist explorers to care for and collect plants to add to their collections.

As the 18th century became the 19th, ethnobotany saw expeditions undertaken with more colonial aims rather than trade economics such as that of Lewis and Clarke which recorded both plants and the peoples encountered use of them. Edward Palmer collected material culture artifacts and botanical specimens from people in the North American West (Great Basin) and Mexico from the 1860s to the 1890s. Through all of this research, the field of "aboriginal botany" was established—the study of all forms of the vegetable world which aboriginal peoples use for food, medicine, textiles, ornaments and more. [13]

Development and application in modern science

The first individual to study the emic perspective of the plant world was a German physician working in Sarajevo at the end of the 19th century: Leopold Glück. His published work on traditional medical uses of plants done by rural people in Bosnia (1896) has to be considered the first modern ethnobotanical work. [14]

Other scholars analyzed uses of plants under an indigenous/local perspective in the 20th century: Matilda Coxe Stevenson, Zuni plants (1915); Frank Cushing, Zuni foods (1920); Keewaydinoquay Peschel, Anishinaabe fungi (1998), and the team approach of Wilfred Robbins, John Peabody Harrington, and Barbara Freire-Marreco, Tewa pueblo plants (1916).

In the beginning, ethonobotanical specimens and studies were not very reliable and sometimes not helpful. This is because the botanists and the anthropologists did not always collaborate in their work. The botanists focused on identifying species and how the plants were used instead of concentrating upon how plants fit into people's lives. On the other hand, anthropologists were interested in the cultural role of plants and treated other scientific aspects superficially. In the early 20th century, botanists and anthropologists better collaborated and the collection of reliable, detailed cross-disciplinary data began.

Beginning in the 20th century, the field of ethnobotany experienced a shift from the raw compilation of data to a greater methodological and conceptual reorientation. This is also the beginning of academic ethnobotany. The so-called "father" of this discipline is Richard Evans Schultes, even though he did not actually coin the term "ethnobotany". Today the field of ethnobotany requires a variety of skills: botanical training for the identification and preservation of plant specimens; anthropological training to understand the cultural concepts around the perception of plants; linguistic training, at least enough to transcribe local terms and understand native morphology, syntax, and semantics.

Mark Plotkin, who studied at Harvard University, the Yale School of Forestry and Tufts University, has contributed a number of books on ethnobotany. He completed a handbook for the Tirio people of Suriname detailing their medicinal plants; Tales of a Shaman's Apprentice (1994); The Shaman's Apprentice, a children's book with Lynne Cherry (1998); and Medicine Quest: In Search of Nature's Healing Secrets (2000).

Plotkin was interviewed in 1998 by South American Explorer magazine, just after the release of Tales of a Shaman's Apprentice and the IMAX movie Amazonia. In the book, he stated that he saw wisdom in both traditional and Western forms of medicine:

No medical system has all the answers—no shaman that I've worked with has the equivalent of a polio vaccine and no dermatologist that I've been to could cure a fungal infection as effectively (and inexpensively) as some of my Amazonian mentors. It shouldn't be the doctor versus the witch doctor. It should be the best aspects of all medical systems (ayurvedic, herbalism, homeopathic, and so on) combined in a way which makes health care more effective and more affordable for all. [15]

A great deal of information about the traditional uses of plants is still intact with tribal peoples. [16] But the native healers are often reluctant to accurately share their knowledge to outsiders. Schultes actually apprenticed himself to an Amazonian shaman, which involves a long-term commitment and genuine relationship. In Wind in the Blood: Mayan Healing & Chinese Medicine by Garcia et al. the visiting acupuncturists were able to access levels of Mayan medicine that anthropologists could not because they had something to share in exchange. Cherokee medicine priest David Winston describes how his uncle would invent nonsense to satisfy visiting anthropologists. [17]

Another scholar, James W. Herrick, who studied under ethnologist William N. Fenton, in his work Iroquois Medical Ethnobotany (1995) with Dean R. Snow (editor), professor of Anthropology at Penn State, explains that understanding herbal medicines in traditional Iroquois cultures is rooted in a strong and ancient cosmological belief system. [18] Their work provides perceptions and conceptions of illness and imbalances which can manifest in physical forms from benign maladies to serious diseases. It also includes a large compilation of Herrick’s field work from numerous Iroquois authorities of over 450 names, uses, and preparations of plants for various ailments. Traditional Iroquois practitioners had (and have) a sophisticated perspective on the plant world that contrast strikingly with that of modern medical science. [19]

Researcher Cassandra Quave at Emory University has used ethnobotany to address the problems that arise from antibiotic resistance. Quave notes that the advantage of medical ethnobotany over Western medicine rests in the difference in mechanism. For example, elmleaf blackberry extract focuses instead on the prevention of bacterial collaboration as opposed to directly exterminating them. [20]


Many instances of gender bias have occurred in ethnobotany, creating the risk of drawing erroneous conclusions. Anthropologists would often consult with primarily men. In Las Pavas, a small farming community in Panama, anthropologists drew conclusions about the entire community's use of plant from their conversations and lessons with mostly men. They consulted with 40 families, but the women only participated rarely in interviews and never joined them in the field. Due to the division of labor, the knowledge of wild plants for food, medicine, and fibers, among others, was left out of the picture, resulting in a distorted view of which plants were actually important to them. [21] [22]

Ethnobotanists have also assumed that ownership of a resource means familiarity with that resource. In some societies women are excluded from owning land, while being the ones who work it. Inaccurate data can come from interviewing only the owners. [23]

Other issues include ethical concerns regarding interactions with indigenous populations, and the International Society of Ethnobiology has created a code of ethics to guide researchers. [24]
