Spring is nettle season. That’s when the young stinging leaves are richest in vitamins, and that’s when people start harvesting them, steeping them, adding them to food, and using them for hair care. A plant that has “stood up for itself” for centuries is actually one of the most nutritious and accessible medicinal herbs in temperate climates.
Why nettles sting
The Latin name for nettle is Urtica, from urere — “to burn.” That’s not just poetic. The leaves are covered in stinging hairs: when touched, the tips break off, the sharp edges pierce the skin, and they inject formic acid into the skin — almost like a microscopic syringe.
In most cases, that sting goes away on its own and isn’t dangerous. It can even mildly irritate the skin and boost circulation, which is why people historically used nettle stings to treat rheumatism. Modern medicine, however, does not consider that method therapeutic.
What’s inside nettles: vitamins, minerals, and more
Nettle is one of the leaders among plants for the number of beneficial compounds in its leaves. It contains:
- Vitamins — vitamin C, vitamin K, vitamin A, vitamin E, and the B complex. Vitamin K helps blood clot and reduce inflammation; beta-carotene supports visual sharpness; vitamin C supports immune defense.
- Minerals — iron, calcium (mostly as carbonate, which is easier on the kidneys), magnesium, zinc, selenium, copper, and phosphorus.
- Other compounds — chlorophyll, flavonoids, tannins, phytoncides, quercetin, and organic acids (formic, caffeic, and ferulic acids).
For comparison: 100 g of nettle contains more iron than the same amount of spinach and about as much calcium as a glass of milk.
How nettles benefit your body
Because of that composition, people have used nettle for centuries both as a medicinal raw material and as food. Hippocrates and Dioscorides wrote about its properties — nettle’s ability to stop bleeding, reduce inflammation, and act as a diuretic has been known for over two thousand years. Pliny the Elder and Avicenna used nettle for bleeding, inflammation, skin diseases, and rheumatism.
Today nettle is an officially recognized medicinal plant. Its dry extract is an ingredient in the pharmaceutical drug Allochol, which doctors prescribe for liver and biliary tract disorders.
Main proven effects of nettle include:
- Nettle increases hemoglobin levels and raises red blood cell counts.
- Nettle strengthens the immune system thanks to vitamin C and other biologically active compounds.
- Nettle improves the metabolism of carbohydrates and proteins.
- Nettle has anti-inflammatory, astringent, diuretic, and hemostatic (blood-stopping) effects.
- Nettle helps remove toxins thanks to its cellulose and lignin content.
- Nettle aids treatment of gallbladder and liver conditions and helps with chronic constipation.
- Nettle can contribute to lowering blood sugar levels.
When nettles can do more harm than good
Despite its benefits, nettle is not a universal remedy. There are conditions in which people should avoid it or use it with caution.
Nettle is not recommended for people with:
- increased blood clotting (hypercoagulability) or those taking anticoagulant medications
- thrombophlebitis, varicose veins, or atherosclerosis (because of the risk of clot formation)
- kidney disease
- bleeding caused by cysts, polyps, or tumors
- pregnancy, since nettle can cause uterine contractions
- children under 3 years old
In older adults, nettle can lower blood pressure, so people with hypertension should use it cautiously. Consult a doctor before using nettle regularly, especially for therapeutic purposes.
How to use nettles
People use nettle in several forms depending on the intended purpose.
The simplest and most common method is nettle tea or decoction: Steep dried leaves in boiling water for 10–15 minutes and drink in courses of 2–3 weeks. This drink supports the immune system, helps with post-winter fatigue, and provides a gentle tonic effect.
In cooking, add young leaves to soups, salads, mashed potatoes, and pies — but always blanch the leaves with boiling water first, or they will still sting. In spring, this is one of the easiest ways to boost your diet with iron and vitamins.
For hair care, make decoctions and infusions for rinses. Use these rinses as a simple home ritual to help strengthen hair and reduce dandruff. The recipes are straightforward but require regular use to be effective.
Finally — if you want to harvest nettles yourself, learn when to pick them, where not to collect them, and how to store them so they retain their properties.
