If you’re a plant parent, we probably don’t have to tell you about the benefits you reap from keeping your horticultural brood around. Plants are pleasing, soothing and great company—in fact, one 2022 public-health study on the effects of indoor plants found that people who spent time around indoor greenery experienced optimal relaxation and cognitive function.
Anytime you want to take your plant-raising game to the next level, consider another potential advantage: Some plants can actually help you heal. According to Lauren Haynes, a clinical herbalist who trained at the Appalachian Center for Natural Health, “a simple, safe plant is such an easy way to care for yourself and your family…..Story continues…

Human cultivation of plants is the core of agriculture, which in turn has played a key role in the history of world civilizations. Humans depend on plants for food, either directly or as feed in animal husbandry. Agriculture includes agronomy for arable crops, horticulture for vegetables and fruit, and forestry for timber. About 7,000 species of plant have been used for food, though most of today’s food is derived from only 30 species.
The major staples include cereals such as rice and wheat, starchy roots and tubers such as cassava and potato, and legumes such as peas and beans. Vegetable oils such as olive oil and palm oil provide lipids, while fruit and vegetables contribute vitamins and minerals to the diet. Coffee, tea, and chocolate are major crops whose caffeine-containing products serve as mild stimulants. The study of plant uses by people is called economic botany or ethnobotany.
Medicinal plants are a primary source of organic compounds, both for their medicinal and physiological effects, and for the industrial synthesis of a vast array of organic chemicals. Many hundreds of medicines, as well as narcotics, are derived from plants, both traditional medicines used in herbalism and chemical substances purified from plants or first identified in them, sometimes by ethnobotanical search, and then synthesised for use in modern medicine.
Modern medicines derived from plants include aspirin, taxol, morphine, quinine, reserpine, colchicine, digitalis and vincristine. Plants used in herbalism include ginkgo, echinacea, feverfew, and Saint John’s wort. The pharmacopoeia of Dioscorides, De materia medica, describing some 600 medicinal plants, was written between 50 and 70 CE and remained in use in Europe and the Middle East until around 1600 CE; it was the precursor of all modern pharmacopoeias.
Plants grown as industrial crops are the source of a wide range of products used in manufacturing. Nonfood products include essential oils, natural dyes, pigments, waxes, resins, tannins, alkaloids, amber and cork. Products derived from plants include soaps, shampoos, perfumes, cosmetics, paint, varnish, turpentine, rubber, latex, lubricants, linoleum, plastics, inks, and gums. Renewable fuels from plants include firewood, peat and other biofuels.
The fossil fuels coal, petroleum and natural gas are derived from the remains of aquatic organisms including phytoplankton in geological time.Many of the coal fields date to the Carboniferous period of Earth’s history. Terrestrial plants also form type III kerogen, a source of natural gas. Structural resources and fibres from plants are used to construct dwellings and to manufacture clothing.
Wood is used for buildings, boats, and furniture, and for smaller items such as musical instruments and sports equipment. Wood is pulped to make paper and cardboard. Cloth is often made from cotton, flax, ramie or synthetic fibres such as rayon, derived from plant cellulose. Thread used to sew cloth likewise comes in large part from cotton.
Thousands of plant species are cultivated for their beauty and to provide shade, modify temperatures, reduce wind, abate noise, provide privacy, and reduce soil erosion. Plants are the basis of a multibillion-dollar per year tourism industry, which includes travel to historic gardens, national parks, rainforests, forests with colourful autumn leaves, and festivals such as Japan’s and America’s cherry blossom festivals.
Plants may be grown indoors as houseplants, or in specialized buildings such as greenhouses. Plants such as Venus flytrap, sensitive plant and resurrection plant are sold as novelties. Art forms specializing in the arrangement of cut or living plant include bonsai, ikebana, and the arrangement of cut or dried flowers. Ornamental plants have sometimes changed the course of history, as in tulipomania.
The traditional study of plants is the science of botany. Basic biological research has often used plants as its model organisms. In genetics, the breeding of pea plants allowed Gregor Mendel to derive the basic laws governing inheritance, and examination of chromosomes in maize allowed Barbara McClintock to demonstrate their connection to inherited traits. The plant Arabidopsis thaliana is used in laboratories as a model organism to understand how genes control the growth and development of plant structures.
Tree rings provide a method of dating in archeology, and a record of past climates. The study of plant fossils, or Paleobotany, provides information about the evolutions of plants, paleogeographical reconstructions, and past climate change. Plant fossils can also help determine the age of rocks. Plants including trees appear in mythology, religion, and literature. In multiple Indo-European, Siberian, and Native American religions, the world tree motif is depicted as a colossal tree growing on the earth, supporting the heavens, and with its roots reaching into the underworld.
It may also appear as a cosmic tree or an eagle and serpent tree. Forms of the world tree include the archetypal tree of life, which is in turn connected to the Eurasian concept of the sacred tree. Another widespread ancient motif, found for example in Iran, has a tree of life flanked by a pair of confronted animals. Flowers are often used as memorials, gifts and to mark special occasions such as births, deaths, weddings and holidays. Flower arrangements may be used to send hidden messages.
Weeds are commercially or aesthetically undesirable plants growing in managed environments such as in agriculture and gardens. People have spread many plants beyond their native ranges; some of these plants have become invasive, damaging existing ecosystems by displacing native species, and sometimes becoming serious weeds of cultivation. Some plants that produce windblown pollen, including grasses, invoke allergic reactions in people who suffer from hay fever.
Many plants produce toxins to protect themselves from herbivores. Major classes of plant toxins include alkaloids, terpenoids, and phenolics. These can be harmful to humans and livestock by ingestion or, as with poison ivy, by contact. Some plants have negative effects on other plants, preventing seedling growth or the growth of nearby plants by releasing allopathic chemicals.
