Bee Is For Borage

"'Perhaps we'd best go down, Sassenach. It's getting a wee bit damp out.' 
We took a different way down, crossing the roof to an outer stairway that led down to the kitchen gardens, where I wanted to pull a bit of borage, if the downpour would let me. We sheltered under the wall of the Castle, one of the jutting window ledges diverting the rain above.  
'What do ye do wi' borage, Sassenach?' Jamie asked with interest, looking out at the straggly vines and plants, beaten to the earth by the rain.
'Well, when it's green, nothing. First you dry it, and then --' 
I was interrupted by a terrific noise of barking and shouting, coming from outside the garden wall."   
- From OUTLANDER, by Diana Gabaldon, chapter 24
We never get an answer to Jamie's question. It appears to have been forgotten as he leaps over the garden wall to rescue Father Bain from an attack by a pack of wild dogs.

But it is likely that an 18th century herbalist would make a tea from the dried leaves as a remedy for depression or to relieve menopausal discomforts. According to Mary Preus, author of the NORTHWEST HERB LOVER'S HANDBOOK, borage has a centuries-long reputation for elevating spirits and bringing comfort after long illness or hard work. As the ancient Greeks used to say, "I Borage bring always courage."

Botanical Information

Family: Boraginaceae
Genus: Borago
Species: Borago officinalis
Common names: Borage (rhymes with "garage," not "porridge"); bee bread; starflower

Borage is an annual herb, native to the Mediterranean region. It grows easily from seed, much like forget-me-nots, which belong to the same botanical family. Borage self-sows so freely that it can become weedy, so keep an eye on it. It can go from seed to seed in just 8 weeks.

Borage has great value in the garden because it is much loved by bees. Take a look.

Medicinal Uses

Borage seed oil has an anti-inflammatory effect on the cells of the body because of its high concentration of GLA (gamma-linoleic acid). It has been found to be effective in the treatment of autoimmune disorders, skin problems, PMS and diabetic neuropathy. This video explains how borage oil and other healthy fats benefit us.

Culinary Uses

Borage flowers are edible and are prized for their true blue color - few flowers in nature are actually blue.  Young borage leaves, which have a cucumber-like flavor, can be added to salads, soups and sauces. Borage is also used to flavor beverages, including cocktails, according to The Drunken Botanist.

It is important to keep in mind, however, that borage leaves contain small amounts of a liver-toxic alkaloid. It is therefore best not to overdo your consumption of this herb.

Claire and the Case for Cleanliness

"...she began digging in a painted wooden chest by the hearth, emerging finally with a pile of ratty cloths.
 'No, that won't do,' I said, fingering them gingerly. 'The wound needs to be disinfected first, then bandaged with a clean cloth, if there are no sterile bandages.' 
Eyebrows rose all around. 'Disinfected?' said the small man, carefully.
 'Yes, indeed,' I said firmly, thinking him a bit simpleminded, in spite of his educated accent. 'All dirt must be removed from the wound and it must be treated with a compound to discourage germs and promote healing.'"
- From OUTLANDER,  Chapter 3, "The Man In The Wood" by Diana Gabaldon
Discouraging "germs" is a bit off- topic for a plant blog. But we are talking here about the Outlander books and Claire Fraser's pragmatic approach to healing. She could use "Russian penicillin," also known as garlic, to treat infection, but why allow infection to take hold in the first place? An ounce of prevention is worth a pound of cure. I'm sure Claire would agree.

In Claire's time, dramatic improvements in human health had been achieved as a result of good hygiene and sanitation practices. But in the 18th century, no one understood that tiny, invisible-to-the-naked-eye organisms were responsible for a host of infectious and deadly diseases. Even though "germ theory" had been around a long time (Aristotle, in 350 BC, advised Alexander the great to "boil drinking water and bury feces, to prevent disease."), the idea didn't really begin to gain widespread attention until the mid-19th century.

In the 1850s, John Snow, a British obstetrician, became convinced that drinking water contaminated with sewage was responsible for outbreaks of cholera in London. His conclusion was met with derision from his contemporaries who "knew" that diseases like cholera were caused by "vapors" or "miasma." The Reverend Henry Whitehead sought to discredit Snow's conclusions, claiming that the disease was an act of God.

But Snow ignored his critics and continued observing and collecting data. In August of 1854, a particularly severe outbreak of cholera occurred in Soho, a London suburb. Determined to prove that contaminated water was the cause, he conducted a study of the victims and where they got their drinking water. Writer Kathleen Tuthill quotes Snow as saying, "Within 250 yards of the spot where Cambridge Street joins Broad Street there were upward of 500 fatal attacks of cholera in 10 days. As soon as I became acquainted with the situation and extent of this irruption (sic) of cholera, I suspected some contamination of the water of the much-frequented street-pump in Broad Street."

In spite of all the evidence he collected, connecting hundreds of cases of cholera with drinking water from the Broad Street pump, his conclusions were still met with skepticism. He finally convinced town officials to take the handle off the pump, at least temporarily, so that no one could draw water from it. The cholera epidemic came to an immediate halt.

Despite this dramatic proof, city officials still refused to clean up sewage systems and assure that drinking water was clean. But Snow's conclusions eventually won out.  In the 1880s, a German doctor, Robert Koch, identified the bacterium, Vibrio cholerae, that causes cholera. His work showed that cholera is spread by way of fecal contamination of food or water.

By the end of the 19th century, cities in Europe and the United States had improved sanitation systems, keeping drinking water separate from sewage. Outbreaks of cholera in those cities became a thing of the past.

Snow is considered a pioneer in public health research, but he was not alone. Louis Pasteur, for whom the process of pasteurization is named; Robert Koch, the founder of modern bateriology mentioned above; Charles Chamberland, whose filter was used in the discovery of viruses; Miles Berkeley, who discovered that potato blight was caused by fungal disease - all made significant discoveries in the last half of the 19th century.

As the chart below illustrates, the benefits of all this knowledge were profound. In the first half of the 20th century, improved sanitation systems, combined with public health education about the importance of cleanliness to prevent the spread of disease, reduced mortality rates from infectious diseases dramatically. The one notable spike in those years was the 1918 flu pandemic, nicknamed the Spanish flu. (Fans of Downton Abbey will remember the episode when Lavinia Swire, Matthew Crawley's fiance, died of the disease.)

By the time Claire was serving as an Army nurse during WWII, mortality rates from infectious diseases had declined by 75% since the turn of the century- and that was before penicillin was widely available. As you can see from the graph, antibiotics did have an effect, but nothing compared to the difference made by good sanitation and hygiene. Let's remember that. Three cheers for soap and clean water!
