In the fairy tale of "The Wild Swans" by Hans Christian Andersen, the heroine's brothers have been turned into swans by their evil stepmother. A kindly fairy instructs her to gather nettles in a graveyard by night, spin their fibers into a prickly green yarn, and then knit the yarn into a coat for each swan brother in order to break the spell -- all of which she must do without speaking a word or her brothers will die. The nettles sting and blister her hands, but she plucks and cards, spins and knits, until the nettle coats are almost done -- running out of time before she can finish the sleeve on the very last coat. She flings the coats onto her swan-brothers and they transform back into young men -- except for the youngest, with the incomplete coat, who is left with a wing in the place of one arm. (And there begins a whole other tale.)
This was one of my favorite stories as a child, for I too had brothers in harm's way, and I too was a silent sister who worked as best I could to keep them safe, and sometimes succeded, and sometimes failed, as the plot of our lives unfolded. The story confirmed that courage can be as painful as knitting coats from nettles, but that goodness can still win out in the end. Spells can broken, and gentle, loving persistence can be the strongest magic of them all.
I grew up with the story, but not with Urtica dioica: "common nettles" or "stinging nettles." I imagined them as dark, thorny, and witchy-looking -- and although they're actually green and ordinary, growing thickly in fields and hedges here in Devon, nettles emerge nonetheless from the loam of old stories and glow with a fairy glamour. It is a plant that heralds the return of spring, a tonic of vitamins and minerals; and also a plant redolent of swans and spells, of love and loss and loyalty, of ancient powers skillfully knotted into the most traditional of women's arts: carding, spinning, knitting, and sewing.
According to the Anglo-Saxon "Nine Herbs Charm," recorded in the 10th century, stiðe (nettles) were used as a protection against "elf-shot" (mysterious pains in humans or livestock caused by the arrows of the elvin folk) and"flying venom" (believed at the time to be one of the four primary causes of illness). In Norse myth, nettles are associated with Thor, the god of Thunder; and with Loki, the trickster god, whose magical fishing net is made from them. In Celtic lore, thick stands of nettles indicate that there are fairy dwellings close by, and the sting of the nettle protects against fairy mischief, black magic, and other forms of sorcery.
Nettles once rivaled flax and hemp (and later, cotton) as a staple fiber for thread and yarn, used to make everything from heavy sailcloth to fine table linen up to the 17th/18th centuries. Other fibers proved more economical as the making of cloth became more mechanized, but in some areas (such as the highlands of Scotland) nettle cloth is still made to this day. "In Scotland, I have eaten nettles," said the 18th century poet Thomas Campbell, "I have slept in nettle sheets, and I have dined off a nettle tablecloth. The young and tender nettle is an excellent potherb. The stalks of the old nettle are as good as flax for making cloth. I have heard my mother say that she thought nettle cloth more durable than any other linen."
"Nettles have numerous virtues," writes Margaret Baker in Discovering the Folklore of Plants. "Nettle oil preceded paraffin; the juice curdled milk and helped to make Cheshire cheese; nettle juice seals leaky barrels; nettles drive frogs from beehives and flies from larders; nettle compost encourages ailing plants; and fruits packed in nettle leaves retain their bloom and freshness.
"Mixing medicine and magic, a healer could cure fever by pulling up a nettle by its roots while speaking the patient's name and those of his parents. Roman soldiers in damp Britain found that rheumatic joints responded to a beating with nettles. Tyroleans threw nettles on the fire to avert thunderstorms, and gathered nettle before sunrise to protect their cattle from evil spirits."
The medicinal value of nettles is confirmed by Julie Bruton-Seal & Matthew Seal in their useful book Hedgerow Medicine:
"Nettle was the Anglo-Saxon sacred herb wergula, and in medieval times nettle beer was drunk for rheumatism. Nettle's high vitamin C content made it a valuable spring tonic for our ancestors after a winter of living on grain and salted meat, with hardly any green vegetables. Nettle soup and porridge were popular spring tonic purifiers, but a pasta or pesto from the leaves is a worthily nutritious modern alternative. Nettle soup is described by one modern writer as 'Springtime herbalism at one of its finest moments.' This soup is the Scottish kail. Tibetans believe that their sage and poet Milarepa (AD 1052-1135) lived solely on nettle soup for many years until he himself turned green: a literal green man.
"Nettles enhance natural immunity, helping protect us from infections. Nettle tea drunk often at the start of a feverish illness is beneficial. Nettles have long been considered a blood tonic and are a wonderful treatment for anaemia, as they are high in both iron and chlorophyll. The iron in nettles is very easily absorbed and assimilated. What cooks will tell you is that two minutes of boiling nettle leaves will neutralize both the silica 'syringes' of the stinging cells and the histamine or formic acid-like solution that is so painful."
Here's our family recipe for Bumblehill Nettle Soup, which is easy to make and delicious:
First, pick your nettles by pinching off the fresh leaves at the tip of the plant, leaving the plant itself intact. It's best to do this in the spring when the vitamin content is highest, before the flowers appear. Rinse your nettle tips in cold water, and cut off any woody bits or thick stems. You need to wear gloves while you handle them, but once the nettles are cooked you can safely eat them without any stinging.
Melt some butter in the bottom of the soup pot, add a chopped onion or two, and cook slowly until softened.
Add a litre or so of vegetable or chicken stock, with salt, pepper, and any herbs you fancy.
Add 2 large potatoes (chopped), a large carrot (chopped), and simmer until almost soft. If you like your soup thick, use more potatoes.
Throw in several large handfuls of fresh nettle leaves, and simmer gently for another 10 minutes.
Add some cream (to taste), and a pinch of nutmeg. Purée with a blender, and serve. (If you happen to have some truffle oil in your pantry, a light sprinkling on the soup tastes terrific.)
Use the left-over nettles for tea, sweetened with honey. Or try these two other good recipes: nettle pancakes and wild nettle bread.
Nettles, folk tales around the world agree, have long been associated with women's domestic magic: with inner strength and fortitude, with healing and also self-healing, with protection and also self-protection, with the ability to "enrich the soil" wherever we have been planted. Nettle magic is steeped in dualities: both fierce and soft, painful and restorative, common as weeds and priceless as jewels. Potent. Tenacious. Humble and often overlooked. Resilient.
And pretty tasty too.
