Borage
Template:Short description {{#invoke:Hatnote|hatnote}} Template:Speciesbox
Borage (Template:IPAc-en<ref>Template:OED</ref> or Template:IPAc-en;<ref>Le Robert et Collins English-French Dictionary and the American Heritage Dictionary</ref> Borago officinalis), also known as starflower, is an annual herb in the flowering plant family Boraginaceae native to the Mediterranean region. Although the plant contains small amounts of pyrrolizidine alkaloids, some parts are edible and its seeds provide oil.
DescriptionEdit
B. officinalis grows to a height of Template:Convert,<ref name="tfb">Template:Cite book</ref> and is bristly or hairy all over the stems and leaves; the leaves are alternate, simple, and Template:Convert long.
The flowers are complete, perfect with five narrow, triangular-pointed petals.<ref name="tfb" /> Flowers are most often blue, although pink flowers are sometimes observed. White-flowered types are also cultivated. The blue flower is genetically dominant over the white flower.<ref name="springerlink.com">Template:Cite journal</ref>
The flowers arise along scorpioid cymes to form large floral displays with multiple flowers blooming simultaneously, suggesting that borage has a high degree of geitonogamy (intraplant pollination).<ref name="springerlink.com"/>
It has an indeterminate growth habit. In temperate climates such as in the UK, its flowering season is relatively long, from June to September. In milder climates, borage blooms continuously for most of the year. It can be invasive.
ChemistryEdit
The seeds consist of 26–38% borage seed oil, of which 17–28% is gamma-linolenic acid (GLA, an omega-6 fatty acid), making borage seed oil the richest known source of GLA.<ref>National Non-Food Crops Centre. NNFCC Crop Factsheet: Borage, Retrieved on 16 Feb 2011</ref> The oil also contains the fatty acids palmitic acid (10–11%), stearic acid (3.5–4.5%), oleic acid (16–20%), linoleic acid (35–38%), eicosenoic acid (3.5–5.5%), erucic acid (1.5–3.5%), and nervonic acid (1.5%). Healthy adults typically produce ample GLA from dietary linoleic acid, but borage seed oil is often marketed as a GLA supplement, under the names "starflower oil" or "borage oil".
The leaves contain small amounts (2–10 ppm in the dried herb) of the liver-toxic pyrrolizidine alkaloids (PA) intermedine, lycopsamine, amabiline, and supinine and the nontoxic saturated PA thesinine.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> PAs are also present in borage seed oil, but may be removed by processing.<ref name="SK">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite journal</ref><ref>Template:Cite journal</ref><ref>Template:Cite journal</ref><ref>Template:Cite book</ref><ref>Template:Cite journal</ref>
Distribution and habitatEdit
It is native to the Mediterranean region, and has naturalized in many other locales.<ref>Altervista Flora Italiana, Borragine comune, gurkört, Borago officinalis L. includes photos, drawings, and European distribution map</ref> It grows satisfactorily in gardens in most of Europe, such as Denmark, France, Germany, the United Kingdom, and Ireland. It is not a perennial, but it remains in the garden from year to year by self-seeding.
ToxicityEdit
In addition to the liver-toxic pyrrolizidine alkaloids found in the leaves and seed oil, the German Federal Institute for Risk Assessment has advised that honey from borage contains pyrrolizidine alkaloids (PAs), transferred to the honey through pollen collected at borage plants, and advise that commercial honey production could select for raw honey with limited PA content to prevent contamination.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
UsesEdit
Traditionally, borage was cultivated for culinary and medicinal uses, although today, commercial cultivation is mainly as an oilseed.
Borage is used as either a fresh vegetable or a dried herb. As a fresh vegetable, borage, with a cucumber-like taste, is often used in salads or as a garnish.<ref name="encyclopedia-of-spices">Template:Cite encyclopedia</ref>
The flower has a sweet, honey-like taste and is often used to decorate desserts and cocktails,<ref name="encyclopedia-of-spices"/> sometimes frozen in ice cubes.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Vegetable use of borage is common in Germany, in the Spanish regions of Aragón and Navarre, on the Greek island of Crete, and in the northern Italian region of Liguria.
Although often used in soups, one of the better known German borage recipes is the Frankfurt speciality grüne Soße ("green sauce").
In Liguria, Italy, borage (in Italian, borragine) is commonly used as a filling of the traditional pasta ravioli and pansoti.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
It is used to flavour pickled gherkins in Poland<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and Russia.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The flowers produce copious nectar<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> which is used by honeybees to make a light and delicate honey.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
BeverageEdit
Borage is traditionally used as a garnish in the Pimms Cup cocktail,<ref name="encyclopedia-of-spices"/> but is nowadays often replaced by a long sliver of cucumber peel or by mint. It is also one of the key botanicals in Gilpin's Westmorland Extra Dry Gin. The author of Cups and their Customs notes that a sprig or two of borage "communicates a peculiar refreshing flavour" to any cool drink.<ref>Template:Cite book</ref>
In Persian cuisine, borage tea (using the dried purple flowers) is called گل گاوزبان : gol gâvzabân, "cow's-tongue-flower".<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Herbal medicineEdit
Traditionally, Borago officinalis has been used in hyperactive gastrointestinal, respiratory and cardiovascular disorders,<ref>Gilani A.H., Bashir S., Khan A.-u. "Pharmacological basis for the use of Borago officinalis in gastrointestinal, respiratory and cardiovascular disorders", Journal of Ethnopharmacology 114 (3), pp 393–399, 2007.</ref> such as gastrointestinal (colic, cramps, diarrhea), airways (asthma, bronchitis), cardiovascular, (cardiotonic, antihypertensive and blood purifier), urinary (diuretic and kidney/bladder disorders).<ref>Gilani A.H. "Focused Conference Group: P16 - Natural products: Past and future? Pharmacological use of borago officinalis", Basic and Clinical Pharmacology and Toxicology. Conference: 16th World Congress of Basic and Clinical Pharmacology. WorldPharma 2010 Copenhagen Denmark. Publication: (var. pagings). 107 (pp. 301), 2010. Date of Publication: July 2010.</ref>
One case of status epilepticus has been reported that was associated with borage oil ingestion.<ref>Template:Cite journal After taking 1.5 to 3 g of borage oil daily for a week; level of GLA in blood was high.</ref>
A methanol extract of borage has shown strong amoebicidal activity in vitro. The 50% inhibitory concentration (Template:LD50) of the extract against Entamoeba histolytica was 33 μg/mLl.<ref>Template:Cite journal</ref>
Companion plantingEdit
Borage is used in companion planting.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It is said to protect or nurse legumes, spinach, brassicas, and strawberries.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It is also said to be a good companion plant to tomatoes because it confuses the mother moths of tomato hornworms or manduca looking for a place to lay their eggs.<ref name="GG">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Claims that it improves tomato growth<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and makes them taste better<ref name="GG" /> remain unsubstantiated.
In cultureEdit
Pliny the Elder and Dioscorides said that borage was the nepenthe (νηπενθές : nēpenthés) mentioned in Homer, which caused forgetfulness when mixed with wine.<ref name="Grieve">Template:Cite book</ref>
King Henry VIII's last wife, Catherine Parr, used borage in a concoction to treat melancholy.<ref>Susan James. Catherine Parr: Henry VIII's Last Love, 2010</ref>
Francis Bacon thought that borage had "an excellent spirit to repress the fuliginous vapour of dusky melancholie".<ref name="Grieve" />
John Gerard's Herball mentions an old verse concerning the plant: "Ego Borago, Gaudia semper ago (I, Borage, bring always joys)". He asserts:
<templatestyles src="Template:Blockquote/styles.css" />
Those of our time do use the flowers in salads to Template:Not a typo and make the mind glad. There be also many things made of these used everywhere for the comfort of the heart, for the driving away of sorrow and increasing the joy of the mind. The leaves and flowers of Borage put into wine make men and women glad and merry and drive away all sadness, dullness and melancholy, as Dioscorides and Pliny affirm. Syrup made of the flowers of Borage comfort the heart, purge melancholy and quiet the frantic and lunatic person. The leaves eaten raw engender good blood, especially in those that have been lately sick.<ref name="Grieve" />{{#if:|{{#if:|}}
