Borage

B. officinalis

B. officinalis grows to a height of 60–100 cm (2 ft 0 in – 3 ft 3 in), and is bristly or hairy all over the stems and leaves; the leaves are alternate, simple, and 5–15 cm (2–6 in) long.

The flowers are complete, perfect with five narrow, triangular-pointed petals. 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.[4]

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).[4]

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.

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 a cucumber-like taste, is often used in salads or as a garnish.[5]

The flower has a sweet, honey-like taste and is often used to decorate desserts and cocktails,[5] most commonly, frozen in ice cubes.[6]

Food

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.[7]

It is used to flavour pickled gherkins in Poland[8] and Russia.[9]

The flowers produce copious nectar[10] which is used by honeybees to make a light and delicate honey.[11]

In Aragonese cuisine, borage boiled and sautéed with garlic is served with potatoes.

The seeds contain 26–38% of borage seed oil, of which 17–28% is gamma-linolenic acid (GLA, an Omega-6 oil), the richest known source.[13]

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%).

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 dietary linoleic acid.

The leaves contain small amounts (2–10 ppm of dried herb) of the liver-toxic pyrrolizidine alkaloids (PA) intermedine, lycopsamine, amabiline, and supinine and the nontoxic saturated PA thesinine.[14] PAs are also present in borage seed oil, but may be removed by processing.[15][16][17][18][19][20]

The German Federal Institute for Risk Assessment has 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.[21]

Traditionally, Borago officinalis has been used in hyperactive gastrointestinal, respiratory and cardiovascular disorders,[22] such as gastrointestinal (colic, cramps, diarrhea), airways (asthma, bronchitis), cardiovascular, (cardiotonic, antihypertensive and blood purifier), urinary (diuretic and kidney/bladder disorders).[23]

One case of status epilepticus has been reported that was associated with borage oil ingestion.[24]

A methanol extract of borage has shown strong amoebicidal activity in vitro. The 50% inhibitory concentration (LD₅₀) of the extract against Entamoeba histolytica was 33 µg/mLl.[25]

Pliny the Elder and Dioscorides said that borage was the nepenthe (νηπενθές : nēpenthés) mentioned in Homer, which caused forgetfulness when mixed with wine.[26]

Francis Bacon thought that borage had "an excellent spirit to repress the fuliginous vapour of dusky melancholie."[26]

John Gerard's Herball mentions 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.[26]

Borage is used in companion planting.[27] It is said to protect or nurse legumes, spinach, brassicas, and even strawberries.[28] 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.[29] Claims that it improves tomato growth[30] and makes them taste better[29] remain unsubstantiated.
