Parsley belongs to the parsley (or carrot) family, '''Apiaceae'''. Also known as the Umbelliferae family (both names, Apiaceae and Umbelliferae, are allowed by the International Code of Botanical Nomenclature), this family comprises unusually aromatic plants with hollow stems, including the [[parsley]], [[carrot]], [[parsnip]], dill, [[caraway]], fennel, and other relatives. The family also includes some highly toxic plants, such as [[hemlock]]. Apiaceae is a large family with about 300 genera and more than 3,000 species. The earlier name ''Umbelliferae'' derives from the inflorescence being in the form of a compound "umbel." The small flowers are radially symmetrical with five small sepals, five petals, and five stamens.

''Petroselinum crispum,'' or parsley, is a self-seeding biennial plant with a single, spindle-shaped [[taproot]], from which grow smooth and many-branched, juicy stems. A biennial plant, it can grow as much as one meter (three feet) in its second year. The alternate compound leaves are bright green and feather-like in appearance, finely divided and tri-[[pinnate]]. Some varieties are flat-leafed and others more curly. The small, five-petaled flowers, which bloom in the second year, are yellow-green and appear in clusters. The seeds are tiny, gray-brown, ribbed, and egg-shaped (ovate) (Hanrahan and Frey 2005).

===Varieties===
+
Though parsley looks similar to [[parsnip]], and parsnips are among the closest relatives of parsley in the [[umbellifer]] family of herbs, these two plants taste quite different. The similarity of the names is a coincidence.
  
−
Two forms of parsley are used as herbs: curly leaf and Italian, or flat leaf (''P. neapolitanum''). Curly leaf parsley is often used as a [[garnish (food)|garnish]]. Many people think flat leaf parsley has a stronger flavor, and this opinion is backed by chemical analysis which finds much higher levels of [[essential oil]] in the flat-leaved [[cultivar]]s{{Fact|date=May 2007}}. One of the compounds of the essential oil is [[apiol]].
+
====Varieties====
−
The use of curly leaf parsley may be favored by some because it cannot be confused with [[poison hemlock]], like flat leaf parsley or [[chervil]].

===Root parsley===

Another type of parsley is grown as a [[root vegetable]], as with '''hamburg root parsley'''. This type of parsley produces much thicker roots than types cultivated for their leaves. Although little known in Britain and the United States, root parsley is very common in Central and Eastern European cuisine, where it is used in most soups or stews.  
+
Although there are more than 30 varieties of parsley, two forms are particularly popular: '''Curly-leaf parsley''' and '''Italian''' or '''flat-leaf parsely''' (Herbst 2001). The flat-leaf variety is known as ''Petroselinum crispum'' var. ''neapolitanum'' (Grin 2008a). A variety known as ''P. crispum'' var. ''crispum'' is commonly known as double curled parsley (Grin 2008b). Curly-leaf parsley is often used as a [[garnish (food)|garnish]]. Italian or flat-leaf parsley generally is considered to have a stronger flavor (Herbst 2001). This view is backed by chemical analysis that finds much higher levels of [[essential oil]] in the flat-leaved [[cultivar]]s. One of the compounds of the essential oil is [[apiol]]. The use of curly-leaf parsley may be favored by some because it cannot be confused with the similar [[hemlock|poison hemlock]] of the same family, such as may happen with flat-leaf parsley.

Though it looks similar to [[parsnip]] it tastes quite different. Parsnips are among the closest relatives of parsley in the [[umbellifer]] family of herbs, although the similarity of the names is a coincidence, parsnip meaning "forked turnip". It is not related to real turnips.
+
Another type of parsley, ''P. crispum'' var. ''tuberosum,'' or ''P. crispum'' Tuberosum Group, is grown as a root vegetable (Grin 2008c). It is commonly known as '''Hamburg parsley''' or turnip-root parsley. This type of parsley produces much thicker roots than types cultivated for their leaves, with a root as much as six times the size as that of garden parsley (Hanrahan and Frey 2005). Although little known in Britain and the United States, root parsley is very common in Central and Eastern European cuisine, where it is used in most soups or stews.

==Uses==
−
Parsley is widely used as a [[companion plant]] in gardens. Like many other [[umbellifer]]s, it attracts predatory insects, including [[parasitic wasp|wasp]]s and predatory [[flies]] to gardens, which then tend to protect plants nearby. They are especially useful for protecting [[tomato]] plants, for example the wasps that kill [[tomato hornworm]]s also eat nectar from parsley. While parsley is [[biennial]], not blooming until its second year, even in its first year it is reputed to help cover up the strong scent of the tomato plant, reducing pest attraction.

 +
 
 +
In parts of Europe, and particularly in West Asia, many foods are served with chopped parsley sprinkled on top. The fresh flavor of parsley goes extremely well with [[fish]]. Parsley is a key ingredient in several [[Southwest Asia|West Asian]] salads, such as [[tabbouleh]], which is the [[national dish]] of [[Lebanon]]. In Southern and Central Europe, parsley is part of [[bouquet garni]], a bundle of fresh herbs used to flavor [[Stock (food)|stocks]], [[soup]]s, and [[sauce]]s. Parsley is often used as a [[garnish (food)|garnish]]. [[Persillade]] is mixture of chopped garlic and chopped parsley. [[Gremolata]] is a mixture of parsley, garlic, and lemon zest.
 +
 
 +
Parsley is sold in bunches and can be refrigerated for up to a week (Herbst 2001). Dried parsley is sold as a [[spice]], but is not similar to the fresh parsley in flavor (Herbst 2001).
 +
 
 +
===Medicinal uses===
 +
The taproot, leaves, and seeds of parsley are used medicinally. Its [[essential oil]], particularly that from the seed, contains the chemicals [[apiole]] and [[myristicin]] and these constituents are diuretic and act as uterine stimulates. The saponin content may help relieve coughs. An advisory panel on herbal medicines, German Commission E, has approved parsley for use in the prevention and treatment of [[kidney stone]]s (Hanrahan and Frey 2005).

*[[herbal tea|Tea]] may be used as an [[enema]]. Chinese and German [[herbalism|herbologists]] recommend parsley tea to help control [[high blood pressure]], and the [[Cherokee Indians]] used it as a [[tonic]] to strengthen the [[Urinary bladder|bladder]].
 +
*Parsley may used as an [[emmenagogue]] and can bring on delayed menstruation (Hanrahan and Frey 2005).
 +
*Parsley also appears to increase [[diuresis]] by inhibiting the [[Na+/K+-ATPase]] pump in the kidney, thereby enhancing [[sodium]] and [[water]] excretion while increasing [[potassium]] reabsorption (Kreydiyyeh and Usta 2002).

Parsley should not be consumed as a drug or supplement by pregnant women. Parsley as an oil, root, leaf, or seed could lead to uterine stimulation and preterm labor (WKH 2006). There is a chemical found in the seeds that has abortifacient properties (Hanrahan and Frey 2005). It also irritates the epithelial tissues of the kidney and should not be used by those with kidney disease without consultation with a physician (Hanrahan and Frey 2005). Parsley is high in [[oxalic acid]], a compound involved in the formation of [[kidney stone]]s and nutrient deficiencies. Parsley oil contains [[furanocoumarins]] and [[psoralens]], which leads to extreme [[photosensitivity]] if used orally.

P. crispum var. tuberosum

Parsley is the common name for a bright green, biennial herb of European origin, Petroselinum crispum, which is extensively cultivated for its leaves, which are used as a garnish or for flavoring food. One variety, the Hamburg parsley (P. crispum var. tuberosum) is cultivated for its edible root. Parsley belongs to the flowering plant family Apiaceae, which also is known as the parsley family.

In addition to the unique flavor and aroma of parsley adding to the delight of nature for humans, the plant also is nutritious, providing high amounts of vitamin C. In addition, the taproot, leaves, and seeds of parsley are used medicinally (Hanrahan and Frey 2005).

Description

The Apiaceae family, to which parsley belongs, is also known as the Umbelliferae family, with both names allowed by the International Code of Botanical Nomenclature. This family comprises unusually aromatic plants with hollow stems, including the carrot, parsnip, dill, cumin, caraway, fennel, and other relatives. The family also includes some highly toxic plants, such as hemlock.

Flat parsley flower.

Apiaceae is a large family with about 300 genera and more than 3,000 species. The earlier name, Umbelliferae, derives from the inflorescence being in the form of a compound "umbel." The small flowers are radially symmetrical with five small sepals, five petals, and five stamens.

Petroselinum crispum, or parsley, is a self-seeding biennial plant with a single, spindle-shaped taproot, from which grow smooth and many-branched, juicy stems. A biennial plant, it can grow as much as one meter (three feet) in its second year. The alternate compound leaves are bright green and feather-like in appearance, finely divided and tri-pinnate. Some varieties are flat-leafed and others more curly. The small, five-petaled flowers, which bloom in the second year, are yellow-green and appear in clusters. The seeds are tiny, gray-brown, ribbed, and egg-shaped (ovate) (Hanrahan and Frey 2005).

Though parsley looks similar to parsnip, and parsnips are among the closest relatives of parsley in the umbellifer family of herbs, these two plants taste quite different. The similarity of the names is a coincidence.

Varieties

Curled parsley.
Flat parsley.

Although there are more than 30 varieties of parsley, two forms are particularly popular: Curly-leaf parsley and Italian or flat-leaf parsely (Herbst 2001). The flat-leaf variety is known as Petroselinum crispum var. neapolitanum (Grin 2008a). A variety known as P. crispum var. crispum is commonly known as double curled parsley (Grin 2008b). Curly-leaf parsley is often used as a garnish. Italian or flat-leaf parsley generally is considered to have a stronger flavor (Herbst 2001). This view is backed by chemical analysis that finds much higher levels of essential oil in the flat-leaved cultivars. One of the compounds of the essential oil is apiol. The use of curly-leaf parsley may be favored by some because it cannot be confused with the similar poison hemlock of the same family, such as may happen with flat-leaf parsley.

Another type of parsley, P. crispum var. tuberosum, or P. crispum Tuberosum Group, is grown as a root vegetable (Grin 2008c). It is commonly known as Hamburg parsley or turnip-root parsley. This type of parsley produces much thicker roots than types cultivated for their leaves, with a root as much as six times the size as that of garden parsley (Hanrahan and Frey 2005). Although little known in Britain and the United States, root parsley is very common in Central and Eastern European cuisine, where it is used in most soups or stews.

Cultivation

Parsley bush

Parsley's germination is notoriously slow and inconsistent and may require three to six weeks (Jett). Tales have been told concerning its lengthy germination, with some suggesting that "germination was slow because the seeds had to travel to hell and back two, three, seven, or nine times (depending on sources) before they could grow" (Jett). Hanrahan and Frey (2005) report that in ancient times, parsley was dedicated to Persephone, the wife of Hades and goddess of the underworld.

Furanocoumarins in parsley's seed coat may be responsible for parsley's problematic germination. These compounds may inhibit the germination of other seeds, allowing parsley to compete with nearby plants. However, parsley itself may be affected by the furanocoumarins. Soaking parsley seeds overnight before sowing will shorten the germination period (Jett).

Parsley grows well in deep pots, which helps accommodate the long taproot. Parsley grown indoors requires at least five hours of sunlight a day.

Parsley is used as a garnish and to flavor foods. It is very common in Middle Eastern, European, and American cooking. Parsley is used for its leaf in much the same way as coriander (which is also known as Chinese parsley or cilantro), although it has a milder flavor.

In parts of Europe, and particularly in West Asia, many foods are served with chopped parsley sprinkled on top. The fresh flavor of parsley goes extremely well with fish. Parsley is a key ingredient in several West Asian salads, such as tabbouleh, which is the national dish of Lebanon. In Southern and Central Europe, parsley is part of bouquet garni, a bundle of fresh herbs used to flavor stocks, soups, and sauces. Parsley is often used as a garnish. Persillade is mixture of chopped garlic and chopped parsley. Gremolata is a mixture of parsley, garlic, and lemon zest.

Parsley is sold in bunches and can be refrigerated for up to a week (Herbst 2001). Dried parsley is sold as a spice, but is not similar to the fresh parsley in flavor (Herbst 2001).

Medicinal uses

The taproot, leaves, and seeds of parsley are used medicinally. Its essential oil, particularly that from the seed, contains the chemicals apiole and myristicin and these constituents are diuretic and act as uterine stimulates. The saponin content may help relieve coughs. An advisory panel on herbal medicines, German Commission E, has approved parsley for use in the prevention and treatment of kidney stones (Hanrahan and Frey 2005).

Other medicinal uses include:

  • Tea may be used as an enema. Chinese and German herbologists recommend parsley tea to help control high blood pressure, and the Cherokee Indians used it as a tonic to strengthen the bladder.
  • Parsley may used as an emmenagogue and can bring on delayed menstruation (Hanrahan and Frey 2005).
  • Parsley also appears to increase diuresis by inhibiting the Na+/K+-ATPase pump in the kidney, thereby enhancing sodium and water excretion while increasing potassium reabsorption (Kreydiyyeh and Usta 2002).
  • When crushed and rubbed on the skin, parsley, which inhibits the secretion of histamine, can reduce itching in mosquito bites; it is used in treating hives and other allergy symptoms (Hanrahan and Frey 2005).

Health risks

Parsley should not be consumed as a drug or supplement by pregnant women. Parsley as an oil, root, leaf, or seed could lead to uterine stimulation and preterm labor (WKH 2006). There is a chemical found in the seeds that has abortifacient properties (Hanrahan and Frey 2005). It also irritates the epithelial tissues of the kidney and should not be used by those with kidney disease without consultation with a physician (Hanrahan and Frey 2005). Parsley is high in oxalic acid, a compound involved in the formation of kidney stones and nutrient deficiencies. Parsley oil contains furanocoumarins and psoralens, which leads to extreme photosensitivity if used orally.

Companion plant

Parsley is widely used as a companion plant in gardens. Like many other umbellifers, it attracts predatory insects, including wasps and predatory flies to gardens, which then tend to protect plants nearby. They are especially useful for protecting tomato plants, for example, the wasps that kill tomato hornworms also eat nectar from parsley. While parsley is biennial, not blooming until its second year, even in its first year it is reputed to help cover up the strong scent of the tomato plant, reducing pest attraction.
