Plant Herbs

A(n) herb is a plant that is valued for qualities such as medicinal properties, flavor, scent, or the like.

Uses of Plant Herbs

Herbs have a variety of uses including culinary, medicinal, or in some cases even spiritual usage. General usage differs between culinary herbs and medicinal herbs. In medicinal or spiritual use any of the parts of the plant might be considered "herbs", including leaves, roots, flowers, seeds, resin, root bark, inner bark (cambium), berries and sometimes the pericarp or other portions of the plant.

Culinary herbs

Culinary use of the term "herb" typically distinguishes between herbs, from the leafy green parts of a plant, and spices, from other parts of the plant (including seeds, berries, bark, root, fruit, and even occasionally dried leaves). Culinary herbs are distinguished from vegetables in that like spices they are used in small amounts and provide flavor rather than substance to food.


Some culinary herbs are 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 contain both a spice and an herb, as in, dill seed and dill weed or cilantro (leaves) and coriander (seeds).

Medicinal herbs

Plants contain phytochemicals that have effects on the body. There may be some effects even 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. However, large amounts of these herbs may lead to poisoning, and should be used with caution. One herb-like substance, called Shilajit, may actually help lower blood glucose levels which is especially important for those suffering from diabetes.
Some herbs are used not only for culinary and medicinal purposes, but also for recreational purposes; one such herb is cannabis.

Religious herbs

Herbs are used in many religions – such as in Christianity (myrrh (Commiphora myrrha), ague root (Aletris farinosa) and frankincense (Boswellia spp)) and in the partially Christianized Anglo-Saxon pagan Nine Herbs Charm. In Hinduism a form of Basil called Tulsi is worshipped as a goddess for its medicinal value since the Vedic times. Many Hindus have a Tulsi plant in front of their houses.

Botanical herbs

Main article: Herbaceous plant
In botanical usage a herb or herbaceous plant is any non-woody plant, regardless of its flavor, scent or other properties. A botanical herb cannot therefore be a woody plant such as a tree or shrub.
