What is Ethnobotany?

Ethnobotany (word invented in 1895 - is the study of how indigeneous peoples used (and are still using) native plants for edible purposes, medicinally, for utilitarian purposes, and for a plethora of other activities. This study is not just historical, because many of the natural remedies used by natives for thousands of years are still just as applicable today (to a much broader population), despite often being refuted or ignored by the professional medical community. One such example is jewelweed, used by North American natives and now popular as a poison ivy remedy.

Global Ethnobotany

Just about every region of the world has some form of ethnobotany, and, although not every old custom is applicable today, many still are and could provide alternative solutions to widespread problems. Truly, there is a worldwide pharmacological treasure waiting to be uncovered (or rather, recovered). Do to the vast amount of knowledge available from around the world, a broad overview will be provided here for brevity's sake.

Native American (North American) Ethnobotany

The tribes that once dominated what is now the United States and Canada had an amazing range of botanical knowledge which passed down from generation to generation, even to the present day. There is practically no plant, weed or crop, tree or shrub, that does not have a use in Native American ethnobotany. It is a miracle that such uses and cures have survived thousands of years of change, and it is to our advantage to learn about them. Below are listed just a few of the most recognizable plants used extensively by Native American tribes.

Flowering Dogwood (Cornus florida L.)


Tribes that used it: Cherokee, Delaware, Houma, Iroquois, Rappahannock.

Medicinal uses: The bark of the dogwood tree was prepared in a variety of ways to treat headaches, measles, worms, backaches, and ulcers. The root bark too was used to treat fevers, prevent infection, treat diarrhea, and as an astringent. An infusion of dogwood flowers was used to treat the flu and colic. The roots and bark were also used by the Houma tribe to treat malaria.

Edible uses: N/A

Utilitarian uses: Cherokees used wood from flowering dogwood to carve on and to fashion loom shuttles.

Eastern Teaberry (Gaultheria procumbens L.)


A.K.A.: wintergreen, checkerberry

Tribes that used it: Algonquin, Cherokee, Chippewa, Delaware, Iroquois, Menominee, Mohegan, Ojibwa, Potawatomi, Shinnecock, Abnaki,

Medicinal uses: Native Americans used poultices or infusions of this beautiful evergreen shrub to treat colds, stomachache, and /  or grippe. The minty leaves were also chewed for dysentery and to treat sore gums. It was also used as a blood purifier, for kidney problems, for rheumatism, for worms, fevers, and arthritis.

Edible uses: Several tribes used teaberry leaves to make tea and ate their delicious red berries (they are as good as they look). Some tribes even made cakes out of the berries.

Utilitarian uses: The Cherokee used the leaves as a replacement for chewing tobacco.

Sweet Birch (Betula lenta L.)


Tribes that used it: Algonquin, Cherokee, Chippewa, Iroquois, Mohegan, Ojibwa.

Medicinal uses: Cherokees chewed on the leaves of sweet birch to help relieve dysentery, and the bark was used to treat diarrhea, pneumonia, urine problems, and stomach problems. Additionally, the Mohegan tribe used the phloem (inner bark) in a tonic.

Edible uses: The Iroquois tribe used sweet birch twigs as part of a beverage.

Utilitarian uses: The Ojibwa tribe used sweet birch's bark in a variety of creative manners, including use in shelters / homes; in coffins; in canoes; and all sorts of containers, baskets, and dishes.

Central and South American Ethnobotany

Many of the modern foods and medicines that we take for granted today originated in South and Central American ethnobotany (such as potatoes and tomatoes). Similar botanical treasures still lie virtually undiscovered (by modern society) in this part of the world.

Cushaw (Cucurbita argyrosperma Huber)

Image Source: Missouri State University

A versatile vegetable used by the peoples of Southern Mexico for as long as 7,000 years. Some of its relatives include types of pumpkin and squash ( Cucurbita pepo L., Cucurbita moschata).

Edible uses: The stems, flowers, and fruit are eaten, and the ripened fruit are also fed to animals. The most popular food source from cushaw, however, is actually its grain, due to its superior amounts of oil and protein (44%).

Medicinal uses: The peoples of the Yucatan used the fleshy parts of cushaw fruit to treat dermatological problems, including burns. A combination of seeds and water also served as an anesthesia.

Quinoa (Chenopodium quinoa)

A very nutritious grain used by tribes in the Andes Mountains for millennia before the arrival of Columbus.

Edible uses: The quinoa plant has a variety of edible uses; its seeds (grain), leaves, and young ears are all edible. They can be made into flour, soap, sauces, salad, and more. Yet this isn't just your ordinary vegetable; quinoa has a number of nutritional benefits as well.

Nutritional value: Quinoa contains large amounts of proteins, which consists of several essential amino acids, most notably lysine. According to a study by the University of Chile, "It has remarkable nutritional properties; not only from its protein content (15%) but also from its great amino acid balance."

In fact, it's so nutritionally balanced that NASA considered using it in their Controlled Ecological Life Support System (CELSS) for extend space missions.

Medicinal uses: The upper parts of the quinoa plant have been used for their pain-killing (specifically for toothache) and anti-inflammatory properties.

Practical uses: Quinoa is used to scare away insects.

A malaria-cure discovered in the Andes Mountains of South America.

Medicinal uses: Indigenous peoples used an infusion of t

e bark to treat fevers. As Jesuit missionaries and many Europeans soon discovered, it also effectively treated malaria (first shipped to Europe around 1631 to 1632). How? Cinchona trees' bark contains the chemical quinine, an effective malaria-fighting substance.

Ever since it was discovered by explorers, it became increasingly popular throughout Europe and Asia, nearly disappearing from its South American home because of over-demand. Today it is being considered again as an alternative to synthetic malaria antidotes.

Guinea arrowroot is an indigenous vegetable used in a variety of ways for a thousand years, although it has become less popular in recent decades.

Edible uses: Guinea arrowroot's roots are fixed with water to make a crisp, cooked vegetable. Guinea arrowroot is also an ingredient in other recipes.

Medicinal uses: The leaves can be prepared and taken to to improve urine flow and to help with urinary bladder inflammation.

Utilitarian uses: The tough leaves are used to make clothes for infants.

(Source: Neglected crops 1492 from a different perspective -

Other widely known and eaten plants that originated from Central and South America include the potato (Solanum tuberosum), tomato (Lycopersicon esculentum), chili pepper (Capsicum annuum), cacao (later known as chocolate) (Theobroma cacao), vanilla (Vanilla planifolia), pineapple (Ananas comosus), and peanuts (Arachis spp.), to name just a handful. These now famous plants were once obscure ethnobotanical specimens, stumbled upon by explorers from the Old World. Likewise, many ethnobotanical treasures only known by a handful of specialists today could be the new centerpiece of world agriculture tomorrow.

Purselane (Portulaca oleracea L.)

Image source: USDA, Dale Ritchey

An important food source and medicinal herb in Italy since ancient times, even being included in the writings of Pliny and Dioscorides. It is a weed in the U.S. and little appreciated for its wealth of nutrition.

Medicinal uses: Purselane was often used in earlier times to sooth a variety of illnesses and pains, some of which include eye pain, toothaches, headaches, fevers, scurvy, and intestinal worms. Modern research has confirmed many of these traditional uses. Purselane can be used to relax the muscles, stop convulsions, and relieve pains and inflammation. Purselane has also been used as a veterinary medicine.

Edible uses: All parts of the purselane plant are edible. It has been eaten since at least the 1st century A.D. as a vegetable. Cooked in oil with garlic, it is said to even taste like pork. It is a very nutritious and was very popular for many centuries, being used by ancient Italians (Romans), monks, and sailors (for scurvy) alike.

Nutritional value: Purselane is a rich source of proteins; minerals; and vitamins A, B6, C (which is why is was popular for preventing scurvy, and E), among other beneficial substance. Also, out of all the leafy greens grown in gardens, purselane contains the greatest amount of omega-3s, making it a good dietary vegetable.

The Future of Ethnobotany

Clearly, there is much to be learned from the past which can in turn be applied to the future; this is a great part of what ethnobotany is all about. These old remedies, fused with modern technologies and inventions, present potentially a great revolution in the pharmacological sciences as well as food sciences. Plants and humans have been living symbiotically for millennia, and plants have influenced our world and society in more ways than one. It is therefore our responsibility to continue this tradition by looking into the ancient tradition of ethnomedicinal and edible knowledge and passing it down to future generations. These benefits which can be derived from plants should not just be a note in a history book; they are real and applicable assets, which, now released on a global scale, could become true panaceas. God has provided us with age old solutions to both very old and new problems facing our societies, and we should use them.

This is but a sampling of the ethnobotanical knowledge from around the world, meant to "wet your appetite." If you are interested in the field of ethnobotany, do some research on your own. The following links can be good places to start.
