It’s that time of year again! It seemed like one day there was hardly anything green and the next the lane was covered in fresh young nettles, assuring me that, despite some cold evenings this week, spring has well and truly sprung.
I have written a few posts on nettles in the past and do excuse me if I repeat myself a little, but this time I wanted to go into a bit more detail on why nettle is so fantastic, as both food and medicine.
This is the time of year when we are both a bit deficient and a bit stagnant as we reach the end of the long winter months. Our bodies slow down during the cold weather, fluids thicken and we are generally less active as well as tending to eat more rich or stodgy meals and less fresh foods. I wrote in my post on January detox recently that often the foods we think of as either ‘cleansing’ or ‘nourishing’ can be just the same thing- and there is no finer example of this than the lovely nettle herself.
For a start nettle is one of the most nutrient dense wild foods that we have readily available to us. High in calcium, chromium, magnesium, zinc, iron, selenium, potassium, trace minerals, protein and many vitamins including A and C, nettle is a very good all round nourishing tonic herb. Nettle has a good reputation as an iron tonic, not just because it contains relatively high levels but because it also contains amino acids and vitamin C which are both required as co-factors for iron absorption. This is the beauty of our nutritive herbs, unlike the average vitamin and mineral supplement, the constituents are presented in a balanced way which allows for greater assimilation and absorption but also prevents excessive build-up. Nettle contains tannins which will tone the mucus membranes of the digestive tract and also prevent too much iron absorption. Nature is so much cleverer than we are.
Nettle is also high in flavonoids, including quercetin and rutin, as well as chlorophyll, both of which help to improve the health of the blood and circulatory system. All this and more has led to nettles reputation as a blood tonic. In traditional Western herbal medicine nettle was considered specific for pale, tired, anaemic people and has been used by practitioners of Chinese medicine to treat what is called blood deficiency. This is not just what we think of as anaemia but a more complex picture of the health of the blood as a whole. If, like me, you are vegetarian or vegan then nettle is one of the best things you can include in your diet to ensure your blood stays healthy and vital. Nettle has long been used as a hair tonic as it feeds the follicles through increasing the health and nutrient content of the blood and I always notice how quickly and strongly my hair and nails grow when taking it regularly.
Through its nutritive action on the blood and body fluids, its cleansing action via the organs of elimination and its tonifying action on the mucus membranes, nettle will have an effect on the whole body and this is one of the reasons that, like so many of our herbs, it is hard to put into rigid categories. The effects of having well nourished blood will include more energy, better circulation, improved mental clarity and better sleep. Effects on the mucus membranes might include improved digestion, increased kidney function or relief from chronic lung symptoms such as coughing wheezing and phlegm. It can be very tempting in today’s climate to look for a more reductionist explanation of how herbs work – the ‘this chemical constituent has this action’- approach to treatment, but herbs are, by their very nature, holistic in the way the act and that is part of their wonder.
Nettle is a prime remedy for treating fatigue and blood sugar balancing. Nettle can help to regulate body metabolism and has been used for the entire endocrine system, from balancing the thyroid, strengthening adrenal function and restoring the reproductive organs. According to Chinese herbalist Peter Holmes, ” Nettle herb provides excellent support for complex metabolic disorders, especially when they involve the connective tissue and/or endocrine glands and metabolic toxicosis – insufficient breakdown of metabolic wastes.” I think it works on blood sugar levels both directly and also indirectly as, by energising us and increasing vitality, it reduces cravings for artificially stimuating foods like sugar and caffieine.
Nettle has astringent, toning and cleansing properties that enable the liver, kidneys, skin and lungs to all work more effectively, thus increasing natural detoxification. It helps to drain damp, or excessive and stagnant fluids in the body, and has been used to help oedema, resolve problems of chronic phlegm and reduce accumulations in conditions such as arthritis and gout. It is a herb we commonly turn to for atopic conditions such as eczema, asthma, allergies and hayfever. Though it is useful for most people with these conditions, in a very few others it can actually cause allergies. Because of its astringent nature it is considered a haemostatic and can help to check excessive bleeding in the body when taken internally.
The energetics of nettles have been somewhat disputed over the centuries. Because of it’s stimulating and moving qualities it was once considered hot, notably by Culpepper who considered it a herb of Mars- hot and dry. Most modern herbalists however consider it cooling and drying. At the risk of being a non-committal fence sitter, I tend to think of it as fairly neutral in temperature, mostly because of it’s nutritive and balancing properties. Being astringent, it is certainly towards the drier end of things but again, how much so will depend on numerous other factors such as environment and climate. In Ayurvedic medicine nettle is considered to increase Vata, because it is cooling and drying, and decrease pitta and kapha. However in the Western tradition it would have been considered mostly quite specific for Vata type people who are often thin, pale, emotionally scattered and dreamy, though it would have been used with more moistening herbs if the person was overly dry. I often think that these kinds of discrepancies are to do with the climate in different areas. For example in northern Europe the climate tends to be very damp so the drying aspects of nettle would not be so problematic but some parts of India may be much drier so people with dry conditions would be more easily aggravated.
There are many ways to include nettle in your diet and here are just a few ideas:
- Raw from the hedgerow – just like this.
- Juiced – mixed with other fruits and veggies such as apples, celery, fennel. ginger, lemon or other greens.
- Tea – One teaspoon of dried nettle herb or two teaspoons of fresh per cup of boiling water makes a nice refreshing and nutrient rich tea.
- Nourishing infusion- Like a very strong tea, this utilises 25g of herb to about a pint of boiling water. Allow it to steep over night in a cafetierre then strain out in the morning and drink throughout the day, providing an abundance of vitamins and minerals. Teas made in this way used to be known as ‘standard infusions’ and were considered both more nutritive and more therapeutic than normal teas. In recent years they have been popularised by Susun Weed as ‘nourishing infusions’ which I think is a lovely way to describe them. After drinking I always use the spent plant material from my nettle infusions as a mulch around my roses.
- Infused vinegar- Loosely fill a jar with fresh nettle tops, cover in apple cider vinegar, cap with a plastic lid and leave to infuse for a month to six weeks. Strain and bottle then add to salads and other dishes. We add a few mls of nettle infused cider vinegar to our hens drinking water to increase their nutrient intake.
- Soup- See my recipes for nettle soup here and here. You can also add powdered nettle or nettle infusions to the stocks of other soups.
- Stir fries, bakes and curries – Slice the nettle tops finely and cook them up just like you would spinach.
- Hair washes and baths- make a strong tea as above and use as a final hair rinse after washing or add to bath water.
Here’s a photo of the nourishing infusion, looks pretty packed with nutrients doesn’t it!
“Our doctors and pharmacists are ashamed of fetching such a common weed from behind the fences to include in their formulas, even though in both cookery and medicine it has proven its mightily impressive effects.” Hieronymus Bock, 1532.
“Nettle is one of the most widely applicable plants in the materia medica. The herb strengthens and supports the whole body.” David Hoffman, 2003.
