Herb

In general use, herbs are plants with savory or aromatic properties that are used for flavoring and garnishing food, medicinal purposes, or for fragrances; excluding vegetables and other plants consumed for macronutrients. 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.--Alcuin and his student Charlemagne In general use, herbs are plants with savory or aromatic properties that are used for flavoring and garnishing food, medicinal purposes, or for fragrances; excluding vegetables and other plants consumed for macronutrients. 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, 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. The word 'herb' is pronounced /hɜːrb/ in Commonwealth English, but /ɜːrb/ is common among North American English speakers and those from other regions where h-dropping occurs. In botany, the word 'herb' is used as a synonym for 'herbaceous plant'. In botany, the term herb refers to a herbaceous plant, 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. Usually the term refers to perennials, although herbaceous plants can also be annuals (where the plant dies at the end of the growing season and grows back from seed next year), or biennials. This term is in contrast to shrubs and trees which possess a woody stem. 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. The word herbaceous is derived from Latin herbāceus meaning 'grassy', from herba 'grass, herb'. Another sense of the term herb can refer to a much larger range of plants, with culinary, therapeutic or other uses. 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. In the wider sense, herbs may be herbaceous perennials but also trees, subshrubs, shrubs, annuals, lianas, ferns, mosses, algae, lichens, and fungi. Herbalism can utilize not just stems and leaves but also fruit, roots, bark and gums. Therefore, one suggested definition of a herb is a plant which is of use to humans, 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. 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). 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. Culinary herbs are distinguished from vegetables in that, like spices, they are used in small amounts and provide flavor rather than substance to food. Herbs can be perennials such as thyme, sage or lavender, biennials such as parsley, or annuals like basil. Perennial herbs can be shrubs such as rosemary (Rosmarinus officinalis), or trees such as bay laurel (Laurus nobilis) – this contrasts with botanical herbs, which by definition cannot be woody plants. Some plants are used as both herbs and spices, such as dill weed and dill seed or coriander leaves and seeds. There are also some herbs, such as those in the mint family, that are used for both culinary and medicinal purposes. Emperor Charlemagne (742–814) compiled a list of 74 different herbs that were to be planted in his gardens. The connection between herbs and health is important already in the European Middle Ages--The Forme of Cury (that is, 'cookery') promotes extensive use of herbs, including in salads, and claims in its preface 'the assent and advisement of the masters of physic and philosophy in the King's Court'.
