In general use, herbs are a widely distributed and widespread group of plants, excluding vegetables and other plants consumed for macronutrients, with savory or aromatic properties that are used for flavoring and garnishing food, for medicinal purposes, or for fragrances. Culinary use typically distinguishes herbs from spices. Herbs generally refers to the leafy green or flowering parts of a plant (either fresh or dried), while spices are usually dried and produced from other parts of the plant, including seeds, bark, roots and fruits.


Herbs have a variety of uses including culinary, medicinal, aromatic and in some cases, spiritual. General usage of the term "herb" differs between culinary herbs and medicinal herbs; in medicinal or spiritual use, any parts of the plant might be considered as "herbs", including leaves, roots, flowers, seeds, root bark, inner bark (and cambium), resin and pericarp.

In botany, the term herb refers to a herbaceous plant,[5] defined as a small, seed-bearing plant without a woody stem in which all aerial parts (i.e. above ground) die back to the ground at the end of each growing season.[6] Usually the term refers to perennials,[5] although herbaceous plants can also be annuals (plants that die at the end of the growing season and grow back from seed next year),[7] or biennials.[5] This term is in contrast to shrubs and trees which possess a woody stem.[6] Shrubs and trees are also defined in terms of size, where shrubs are less than ten meters tall, and trees may grow over ten meters.[6] The word herbaceous is derived from Latin herbāceus meaning "grassy", from herba "grass, herb".[8]

Another sense of the term herb can refer to a much larger range of plants,[9] with culinary, therapeutic or other uses.[5] For example, some of the most commonly described herbs such as sage, rosemary and lavender would be excluded from the botanical definition of a herb as they do not die down each year, and they possess woody stems.[7] In the wider sense, herbs may be herbaceous perennials but also trees,[9] subshrubs,[9] shrubs,[9] annuals,[9] lianas,[9] ferns,[9] mosses,[9] algae,[9] lichens,[7] and fungi.[7] Herbalism can utilize not just stems and leaves but also fruit, roots, bark and gums.[7] Therefore, one suggested definition of a herb is a plant which is of use to humans,[7] although this definition is problematic since it could cover a great many plants that are not commonly described as herbs.

Ancient Greek philosopher Theophrastus divided the plant world into trees, shrubs, and herbs.[10] Herbs came to be considered in three groups, namely pot herbs (e.g. onions), sweet herbs (e.g. thyme), and salad herbs (e.g. wild celery).[7] During the seventeenth century as selective breeding changed the plants size and flavor away from the wild plant, pot herbs began to be referred to as vegetables as they were no longer considered only suitable for the pot.[7]

Botany and the study of herbs was, in its infancy, primarily a study of the pharmacological uses of plants. During the Middle Ages, when humoral theory guided medicine, it was posited that foodstuffs, possessing their own humoral qualities, could alter the humoral temperaments of people. Parsley and sage were often used together in medieval cookery, for example in chicken broth, which had developed a reputation as a therapeutic food by the 14th century. One of the most common sauces of the age, green sauce, was made with parsley and often sage as well. In a 14th-century recipe recorded in Latin "for lords, for settling their temperament and whetting their appetite" green sauce is served with a dish of cheese and whole egg yolks boiled in watered down wine with herbs and spices.[11]

Perennial herbs are usually reproduced by stem cuttings, either softwood cuttings of immature growth, or hardwood cuttings where the bark has been scraped to expose the cambium layer. A cutting will usually be approximately 3 to 4 inches in length. Plant roots can grow from the stems. Leaves are stripped from the lower portion up to one half before the cutting is placed in growth medium or rooted in a glass of water. This process requires high humidity in the environment, sufficient light, and root zone heat.[12]

Some herbs can be infused in boiling water to make herbal teas (also termed tisanes).[5][9] Typically the dried leaves, flowers or seeds are used, or fresh herbs are used.[5] Herbal teas tend to be made from aromatic herbs,[10] may not contain tannins or caffeine,[5] and are not typically mixed with milk.[9] Common examples include chamomile tea,[9] or mint tea.[10] Herbal teas are often used as a source of relaxation or can be associated with rituals.[10]

Herbs were used in prehistoric medicine. As far back as 5000 BCE, evidence that Sumerians used herbs in medicine was inscribed on cuneiform.[15] In 162 CE, the physician Galen was known for concocting complicated herbal remedies that contained up to 100 ingredients.[16]

Some plants contain phytochemicals that have effects on the body. There may be some effects when consumed in the small levels that typify culinary "spicing", and some herbs are toxic in larger quantities. For instance, some types of herbal extract, such as the extract of St. John's-wort (Hypericum perforatum) or of kava (Piper methysticum) can be used for medical purposes to relieve depression and stress.[17] However, large amounts of these herbs may lead to toxic overload that may involve complications, some of a serious nature, and should be used with caution. Complications can also arise when being taken with some prescription medicines.

Herbs have long been used as the basis of traditional Chinese herbal medicine, with usage dating as far back as the first century CE and far before. In India, the Ayurveda medicinal system is based on herbs. Medicinal use of herbs in Western cultures has its roots in the Hippocratic (Greek) elemental healing system, based on a quaternary elemental healing metaphor. Famous herbalist of the Western tradition include Avicenna (Persian), Galen (Roman), Paracelsus (German Swiss), Culpepper (English) and the botanically inclined Eclectic physicians of 19th century/early 20th century America (John Milton Scudder, Harvey Wickes Felter, John Uri Lloyd). Modern pharmaceuticals had their origins in crude herbal medicines, and to this day, some drugs are still extracted as fractionate/isolate compounds from raw herbs and then purified to meet pharmaceutical standards.

Certain herbs contain psychoactive properties that have been used for both religious and recreational purposes by humans since the early Holocene era, notably the leaves and extracts of the cannabis and coca plants. The leaves of the coca plant have been chewed by people in northern Peruvian societies for over 8,000 years,[18] while the use of cannabis as a psychoactive substance dates back to the first century CE in China and northern Africa.[19]

Herbs are used in many religions. During the monastic era, monks would cultivate herbs alongside vegetables, while others would be set aside in a physic garden for specific purposes.[20] For example, myrrh (Commiphora myrrha) and frankincense (Boswellia species) in Hellenistic religion, the nine herbs charm in Anglo-Saxon paganism, neem (Azadirachta indica) leaves, bael (Aegele marmelos) leaves, holy basil or tulsi (Ocimum tenuiflorum), turmeric or "haldi" (Curcuma longa), cannabis in Hinduism, and white sage in Wicca. Rastafari also consider cannabis to be a holy plant.

Siberian shamans also used herbs for spiritual purposes. Plants may be used to induce spiritual experiences for rites of passage, such as vision quests in some Native American cultures. The Cherokee Native Americans use both white sage and cedar for spiritual cleansing and smudging.

Originally there was always doubt in ancient societies, especially in the sceptical medium of western traditions, as to the efficacity of herbal medicines. The use of herbal cosmetics dates back to around six centuries ago in the European and Western countries. Mixtures and pastes were often concocted to whiten the face. During the 1940s, herbal cosmetics took a turn with the emerging red lipstick color, with every year gaining a more intense red. Herbal cosmetics come in many forms, such as face creams, scrubs, lipstick, natural fragrances, powders, body oils, deodorants and sunscreens. They activate through the epithelium of sebaceous glands to make the skin more supple. Ayurvedic oils are widely used in India, prized for their natural health-giving properties.[21]

One method and perhaps the best, used to extract natural oils from herbs to make lipstick is partition chromatography. The process involves separation in watery solution, and then the injection of colour under pressure.

Strewing herbs are scattered (strewn) over the floors of dwelling places and other buildings. Such plants usually have fragrant or astringent smells, and many also serve as insecticides (e.g. to repel fleas) or disinfectants. For example, meadowsweet (Filipendula ulmaria) was sometimes strewn across floors in the middle ages because of its sweet smell.[9]

Determining whether herbs, vitamins, and other over-the-counter dietary supplements would be helpful or harmful to you can be challenging. Will a substance work as the label states it will? Is it likely to interact with your cancer medicines? Is it worth the cost?

The United States Food and Drug Administration (FDA) does not evaluate the safety and labeling of dietary supplements before they are sold. Also, the clinical effects of these products are often difficult to predict due to lack of human data. The potencies of herbal supplements are influenced by plants or plant parts used, harvesting and processing methods, and the amounts of active compounds absorbed. We encourage you to discuss any safety concerns with your doctor before using these products. 041b061a72
