Borage

life science Maturity 5-7 Next article →

Borage, known scientifically as Borago officinalis, is a versatile annual herb. It belongs to the Boraginaceae plant family. This plant is native to the Mediterranean region. However, it has become naturalized in many other parts of the world. Today, it grows well in European gardens in countries like France, Germany, and the United Kingdom.

Many people call it the starflower because of its unique appearance. It is valued for its culinary, medicinal, and industrial uses.

The physical structure of borage is very distinct. The plant can grow to a height of 1 meter. Its stems and leaves are covered in bristly hairs. These hairs make the plant feel rough to the touch.

The leaves are long, simple, and grow in an alternate pattern along the stem. The flowers are complete and perfect, meaning they have both male and female parts. They feature five narrow, triangular-pointed petals. Most flowers are blue, but pink and white varieties also exist. The blue color is genetically dominant over the white color.

Interestingly, younger blossoms may appear pink while older ones turn blue.

Borage follows a specific growth and flowering pattern. The flowers grow along scorpioid cymes. These are curved clusters that allow many flowers to bloom at once. This arrangement suggests a high degree of geitonogamy, which is pollination within the same plant. The plant has an indeterminate growth habit. This means it continues to grow and produce flowers over time. In temperate climates like the UK, the flowering season lasts from June to September. In milder climates, borage may bloom continuously throughout most of the year.

History shows that humans have long been fascinated by borage. Ancient writers like Pliny the Elder and Dioscorides linked it to the "nepenthe" mentioned by Homer. This was a substance that caused forgetfulness when mixed with wine. During the Tudor period, Queen Catherine Parr used borage to treat melancholy. The thinker Francis Bacon also believed borage had a spirit that could repress dark moods. Even the herbalist John Gerard wrote verses about the plant bringing joy. These accounts show how deeply the plant was woven into human culture.

One of the most significant aspects of borage is its chemical makeup. The seeds contain between 26% and 38% borage seed oil. This oil is the richest known source of gamma-linolenic acid, or GLA. GLA is an omega-6 fatty acid. The oil also contains several other fatty acids. These include palmitic acid (10–11%), oleic acid (16–20%), and linoleic acid (35–38%). It also contains smaller amounts of stearic, eicosenoic, erucic, and nervonic acids. Because of this high GLA content, the oil is often sold as a supplement under names like "starflower oil."

While useful, borage contains substances that require careful handling. The leaves and oil contain pyrrolizidine alkaloids, or PAs. These are natural chemicals like intermedine, lycopsamine, amabiline, and supinine. Some of these, such as the others mentioned, can be toxic to the liver. These PAs can even be transferred to honey through the pollen collected by bees. Because of this, experts recommend that commercial honey producers monitor PA levels. Processing can sometimes remove these alkaloids from the seed oil.

Borage has many practical applications in modern life. In cooking, the leaves have a cucumber-like taste and are used in salads. In Germany, it is a key ingredient in "grüne Soße," or green sauce. In Italy, it is often cooked to fill ravioli. The flowers have a sweet, honey-like taste and decorate desserts. In gardens, borage acts as a companion plant. It can protect strawberries, spinach, and legumes. It also serves as a trap crop for tomatoes. It confuses moths so they do not lay eggs on the tomato plants. This makes borage a helpful tool for many gardeners.
