Borage(/ˈbʌrɪdʒ/ⓘ[1]or/ˈbɒrɪdʒ/;[2]Borago officinalis), also known asstarflower,is an annualherbin theflowering plantfamilyBoraginaceaenative to theMediterranean region.Although the plant contains small amounts ofpyrrolizidine alkaloids,some parts are edible andits seeds provide oil.

Borage stem

Description[edit]

B. officinalisflower

B. officinalisgrows to a height of60–100 centimetres (2–3+1⁄2feet), and is bristly or hairy all over the stems andleaves;the leaves arealternate,simple,and 5–15 cm (2–6 inches) long.

The flowers arecomplete,perfectwith five narrow, triangular-pointedpetals.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.[3]

The flowers arise alongscorpioid cymesto form large floral displays with multiple flowers blooming simultaneously, suggesting that borage has a high degree ofgeitonogamy(intraplant pollination).[3]

It has an indeterminate growth habit, which may lead to prolific spreading. 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.

Chemistry[edit]

The seeds consist of 26–38%borage seed oil,of which 17–28% isgamma-linolenic acid(GLA, an Omega-6 oil), the richest-known source.[4]

The oil also contains thefatty acidspalmitic 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%), andnervonic acid(1.5%).

The oil is often marketed as "starflower oil" or "borage oil" for use as a GLA supplement, although healthy adults typically produce ample GLA from dietarylinoleic acid.

The leaves contain small amounts (2–10 ppm of dried herb) of theliver-toxicpyrrolizidine alkaloids(PA)intermedine,lycopsamine,amabiline,andsupinineand the nontoxicsaturatedPAthesinine.[5]PAs are also present in borage seed oil, but may be removed by processing.[6][7][8][9][10][11]

Distribution and habitat[edit]

It is native to theMediterranean region,and has naturalized in many other locales.[12]It grows satisfactorily in gardens in most of Europe, such as Denmark, France, Germany, the United Kingdom, and Ireland, remaining in the garden from year to year by self-seeding.

Toxicity[edit]

In addition to the liver-toxic pyrrolizidine alkaloids found in the leaves and seed oil, the GermanFederal Institute for Risk Assessmenthas advised that honey from borage contains 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.[13]

Uses[edit]

A white-flowercultivar
Two blossoms: the younger one is pink, the older blue.

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 acucumber-like taste, is often used in salads or as a garnish.[14]

The flower has a sweet, honey-like taste and is often used to decoratedessertsand cocktails,[14]sometimes frozen in ice cubes.[15]

Vegetable use of borage is common in Germany, in the Spanish regions ofAragónandNavarre,on the Greek island ofCrete,and in the northern Italian region ofLiguria.

Although often used in soups, one of the better known German borage recipes is theFrankfurtspecialitygrüne Soße( "green sauce" ).

In Liguria, Italy, borage (in Italian,borragine) is commonly used as a filling of the traditional pastaravioliandpansoti.[16]

It is used to flavour pickledgherkinsinPoland[17]and Russia.[18]

The flowers produce copious nectar[19]which is used by honeybees to make a light and delicate honey.[20]

InAragonese cuisine,borage boiled and sautéed withgarlicis served withpotatoes.

Beverage[edit]

Borage is traditionally used as agarnishin thePimms Cupcocktail,[14]but is nowadays often replaced by a long sliver of cucumber peel or bymint.It is also one of the key botanicals inGilpin's Westmorland Extra Dry Gin.

InPersiancuisine, borage tea (using the dried purple flowers) is called گل گاوزبان:gol gâvzabân,"cow's-tongue-flower".[21]

Herbal medicine[edit]

Traditionally,Borago officinalishas been used inhyperactivegastrointestinal,respiratoryandcardiovasculardisorders,[22]such as gastrointestinal (colic,cramps,diarrhea), airways (asthma,bronchitis), cardiovascular, (cardiotonic,antihypertensiveand blood purifier),urinary(diuretic and kidney/bladder disorders).[23]

One case ofstatus epilepticushas been reported that was associated with borage oil ingestion.[24]

Amethanolextract of borage has shown strongamoebicidalactivityin vitro.The 50% inhibitory concentration (LD50) of the extract againstEntamoeba histolyticawas 33 μg/mLl.[25]

Companion planting[edit]

Borage is used incompanion planting.[26]It is said to protect or nurselegumes,spinach,brassicas,and evenstrawberries.[27]It is also said to be a good companion plant totomatoesbecause it confuses the mother moths oftomato hornwormsormanducalooking for a place to lay their eggs.[28]Claims that it improves tomato growth[29]and makes them taste better[28]remain unsubstantiated.

In culture[edit]

Pliny the ElderandDioscoridessaid that borage was thenepenthe(νηπενθές: nēpenthés) mentioned inHomer,which caused forgetfulness when mixed with wine.[30]

KingHenry VIII'slast wife,Catherine Parr,used borage in a concoction to treat melancholy.[31]

Francis Baconthought that borage had "an excellent spirit to repress the fuliginous vapour of dusky melancholie".[30]

John Gerard'sHerballmentions an old verse concerning the plant: "Ego Borago, Gaudia semper ago(I, Borage, bring always joys) ". He asserts:

Those of our time do use the flowers in salads to exhilerate 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.[30]
