From Wikipedia, the free encyclopedia

Economic botany can be very broadly defined as a study of relationships between plants and people. Economic botany contributes significantly to anthropology, biology, conservation, botany, and other fields of science. This link between botany and anthropology explores the ways humans use plants for food, shelter, medicines, textiles, and much more.[1]


History of economic botany

Botany itself came about through medicine and the development of herbal remedies.[2] Thus at its advent, botany was economic as well as systematic. As plants became useful for herbals and curatives, their economic value increased. An early set of instructions drawn up by a cosmographer of Charles the fifth instructed explorers to

"determine what are the items of sustenance of the land and which onse are generally used, whether fruits or seeds, and all manner of spices, drugs, or whatever other scents, and find out the time in which one can reproduce the trees, plants, herbs, and fruits that these parts offer, and if the natives use them for medicines, as we do."[3]

Teosinte and rice are two examples of plants modified so that their economic values would increase.



The teosintes are grasses of the genus Zea. Native Americans bred and selected teosinte for the traits we see in corn today (large ears, multiple rows of kernels).[4] The first ears of maize were very short, with only 8 rows of kernels.[5] Modern corn is the result of several hundred generations of selective breeding. Modern corn is incapable of reproducing without human help; the kernels will stay firmly attached to the cob and rot. This doesn't represent a useful adaptation for the species, but is excellent for harvesting and transporting corn.


Rice was first domesticated approximately 5,000 years ago, in Southeast Asia. Rice and American wild rice are believed to have been domesticated separately.[6] Rice variants have been adapted to the tropics where they provide a grain staple, but rice can be grown almost anywhere. The introduction of dwarf rice variants made several rice-producing countries self-sufficient. Rice is suited to countries with high rainfall.

Economically important food plants

Plants that humans use for food are of high economic importance. Research into food plants generally involves increasing the size of the edible plant organ in question, or increasing the areas where the plant can be grown, and less frequently, finding new crop species. Results of such research are often published in the journal Economic Botany. The New Zealand-based Plant and Food Research Institute publishes its own journal on cultivar development and sustainable production systems for high quality produce, and the design and development of new and novel functional foods.[7]

Florida oranges

Citrus has been a major commercial product in Florida since the 19th century. Florida produces over 70% of the U.S. citrus supply.[8] The color of oranges is not related to ripening, but is a serious component for sales. The orange color only develops in areas with cool nighttime temperatures. In tropical climates, growers often expose the fruit to ethylene, to promote the loss of chlorophyll and expose the beta-carotenes (the orange color).[9]

North American apples

Apples are not native to North America, but today the North American continent boasts the greatest diversity of apples in the world.[10] Part of this is due to "Johnny Appleseed," real name John Chapman. Chapman spent 48 years travelling all along the American northwest spreading apple seeds and planting trees. While apples come in literally thousands of varieties, the majority of the apple market is based on three: Red Delicious, Golden Delicious, and Granny Smith.[10] The Red Delicious is the ideal apple, for marketing purposes, for the apple industry. Its large, intensely red, and instantly recognizable.

Economically valuable medicinal plants

Medical research in the U.S. alone has a budget of $95 billion.[11] A large portion of that money is spent on research into plants and plant extracts. Several key medical discoveries have been made by studying plants and the compounds they produce, to see the effect they have on humans.


The Ephedra plant is the natural source of ephedrine, the plants principle alkaloid. Ephedrine is actually a very interesting case of economic botany in medicine. While it has been taken medicinally in the past, ephedrine can be highly toxic.[12] Because of this fact, medical researchers studied the compound and produced pseudoephedrine. This is the medicine you can buy over the counter, in Sudafed and other decongestants. Ephedrine imitates epinephrine in its affect on the human body. Originally developed by the plant as a herbivore deterrent, this compound, studied and refined by researchers, now helps fix allergy symptoms nationwide every year.


One of many herbal remedies out there, Echinacea represents a sizable industry. Many people take echinacea for cold and flu-like symptoms, but studies show that the plant has had mixed success fighting these viruses.[13] However, those same studies show the plant possibly being useful for the treatment of upper respiratory infections. NCCAM is currently studying echinacea for the treatment of upper respiratory infections as well as its effect on the immune system.

Ornamental plants

Ornamental plants can be found in almost any store, and many people have at least one in their home. However, ornamental plants are not limited to houseplants. Landscaping agencies make heavy use of ornamental plants, usually with an accompanying high cost. Trees, shrubs, flowers, and grasses, all of these are planted by professional landscaping agencies regularly, with a large economic effect.
