A(n) herb (or /ˈɝb/; see pronunciation differences) is a plant that is valued for qualities such as medicinal properties, flavor, scent, or the like.
Herbs have a variety of uses including culinary, medicinal, or in some cases even spiritual entheogen
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
, root bark, inner bark (cambium
and sometimes the pericarp
or other portions.
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
, 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 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.
Many 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 recreation can also be used for medicinal purposes such as cannabis.
Herbs are used in many religions
– such as in Christianity

) and frankincense

a form of Basil
is worshipped as a Goddess
for its medicinal value since the Vedic
times. Many Hindus
in fact have a Tulsi
plant in front of their houses.
