What is White dead-nettle?

What is white dead-nettle?

White dead-nettle is a common European wild plant with soft, hooded white flowers. German speakers call it Weiße Taubnessel. It looks much like a stinging nettle, but it does not sting.

It is not related to the stinging nettle at all. It belongs to the mint family. Shops sometimes mix the two names up, so check the Latin name, Lamium album, on the pack.

The dried flowers are the usual part used, most often as a tea. European folk use pointed at coughs, light stomach upsets, period complaints and whitish vaginal discharge. The flowers were also laid on sore or inflamed skin.

Here is the honest verdict. Good human studies are almost absent, so any benefit stays unproven. Long use in tradition is not proof that a remedy works, and not proof that it is safe.

How does White dead-nettle work?

How is it thought to work?

No one has shown in people how white dead-nettle acts. What we have is lab work and a few animal studies.

In test tubes, extracts of the flowers mop up free radicals (unstable molecules that can damage cells). In cell and animal studies, some of its compounds appear to calm inflammation. Lab tests also show weak action against some bacteria.

Whether any of that happens in a person drinking tea is not established.

Two plain ideas sit behind the old uses. The flowers hold mucilage, a slimy fibre that coats the throat and may soothe it. They also hold tannins, which pull surface tissue tight and slightly dry it.

That drying action is the old reason for using the herb on skin and for washes. It is a reasonable idea, not a tested one.

What forms does White dead-nettle come in?

How is it sold?

Dried flowers are by far the most common form. You will also meet a few others.

- Loose dried flowers, brewed as a tea - Tea bags, often blended with other herbs for coughs or for women's health - Liquid tinctures in alcohol - Creams or ointments, usually as a minor ingredient - A cooled brew used as a skin wash or compress - Young leaves eaten as a cooked green in some regions

Quality varies. Flowers should still look pale and smell faintly sweet, not dusty or brown.

Buy from a seller who prints the Latin name. Lamium album is white dead-nettle. Urtica dioica is stinging nettle, a different plant with different uses.

Where it comes from:

What did tradition claim?

White dead-nettle has a long run in European folk practice. Herbalists wrote about it from the late Middle Ages onward.

The flowers were brewed for coughs and chest colds. Country use also covered light stomach upsets and painful periods. A long-standing use was for whitish vaginal discharge, which old texts called the whites.

Outside the body, the plant was used on sore skin, bruises and minor wounds. Cooled tea was used as a gargle and as a wash.

It also fed people. Young shoots were cooked as a spring green in lean seasons, which is one reason the plant was trusted.

In Germany, the official Commission E monograph of the 1980s listed the flowers for mild mucus in the nose and throat, for mild skin inflammation and for discharge. Those listings rested on tradition and on the plant's low risk, not on trials.

What does White dead-nettle help with?

• Mild cough and catarrh (mucus in the nose and throat): This is the most common modern use. The warm tea feels soothing, and mucilage may coat an irritated throat. The German Commission E listed the flowers for this. That listing came from long use, not from trials. No controlled human study shows it shortens a cough. Expect comfort at best.
• Sore throat and mouth irritation, as a gargle: Tradition used a cooled brew as a gargle. Tannins tighten surface tissue, which can feel briefly calming. There is no human trial for this use. Any gargle, including warm salt water, may feel similar. Swallow nothing you are unsure of, and see a doctor for a severe or one-sided sore throat.
• Whitish vaginal discharge, in traditional use: This is the plant's oldest named use in Europe. It survives in some German monographs for non-specific discharge. There is no good human evidence that it helps. More important, discharge has many causes, and some need treatment. New, smelly, green, bloody or painful discharge needs a doctor, not a tea.
• Period cramps and heavy periods, in traditional use: Folk texts recommended the tea for painful and heavy periods. The claim rests on the plant's supposed tightening action. No trial has tested this. Heavy bleeding can signal fibroids, hormone problems or iron loss. If your periods soak through pads hourly, or leave you dizzy, get checked.
• Mild stomach and bowel upset: Tannins and mucilage are the usual explanation for this old use. Both act in the gut, which makes the idea plausible. Plausible is not proven. There is no human trial for bloating, loose stools or stomach ache. Blood in the stool, black stools or lasting pain need medical care.
• Minor skin inflammation, used externally: Compresses of cooled tea were applied to red or sore skin. Lab work shows anti-inflammatory activity in cells. Whether that carries over to human skin has not been shown. Any benefit may come from the cool damp cloth itself. Do not use it on burns, deep cuts or weeping wounds.

Which foods are rich in White dead-nettle?

White dead-nettle is not a nutrient, so no food is rich in it. The plant itself is edible. Young shoots and leaves have been cooked as a spring green in parts of Europe. Pick only from clean ground, well away from roads, dog paths and sprayed fields.

What are the side effects of White dead-nettle?

• Mild stomach upset or nausea, mostly with strong brews
• Dry or puckered feeling in the mouth, from tannins
• Allergic rash, itch or swelling, rarely
• Skin irritation where a compress was applied
• Loose stools in some people

Good to know:

Reported side effects are few and mild. White dead-nettle is not a known toxic plant, and young shoots have been eaten as food.

That said, few people have been studied formally. Rare reactions could exist without being on record.

Allergy is the main thing to watch. Stop at once if you get a rash, itching, swelling of the lips or face, or trouble breathing, and get medical help.

How much White dead-nettle should you take?

• Recommended daily: What do labels usually say? European tea labels commonly give about 1 g of dried flowers per cup. The German Commission E set about 3 g of the dried flower a day. That figure is here to show what a pack carries. It is not a plan for you, and it is not a dose the evidence supports. Tinctures vary far too much to summarise. Follow the product label, and ask a pharmacist if the label is unclear.
• Best time of day: Timing does not matter much. No study has compared times of day. Many people take the tea warm in the evening for a night-time cough. That is about comfort, not about how the herb works. It is not a stimulant and it is not a sedative, so it should not affect sleep either way.
• With or without food: Either is fine. The tea is gentle, and most people drink it between meals. If it unsettles your stomach, try it with food. One practical point: tannins can bind iron. If you take iron tablets, leave about two hours between the tablet and the tea.
• Time to effect: If the tea soothes your throat, you will feel that while you drink it. That effect fades within an hour. For anything else, no honest timeline exists. There is no human trial to draw one from. It may do nothing at all. If a week passes with no change, stop and get advice.
• How long to take it: Traditional use was short. People drank it for a few days while a cold or an upset settled. There is no safety data for long daily use. Nothing says it is harmful, and nothing says it is fine either. A symptom that lasts more than about a week deserves a doctor's look, not a longer course of tea.
