The dead nettle plant is the one that looks like a stinging nettle but can’t sting you. That’s the whole reason for the name — “dead” here means the stinging hairs are absent, not that the plant is dying. Herbalists have used the white-flowered species, Lamium album, for centuries, mostly for heavy periods, wounds, and coughs. What almost nobody mentions is how thin the human evidence behind those uses is.
So this page does two things. It tells you how to recognize dead nettle in the field and tell it apart from the plant it mimics. And it lays out, use by use, which claims have real support, which rest only on tradition, and which you should skip entirely.
What the dead nettle plant is
Lamium album — white dead nettle, white archangel, blind nettle — is a perennial in the mint family (Lamiaceae) that grows to roughly 20 to 24 inches. It has square, hollow stems, opposite pairs of heart-shaped serrated leaves, and whorls of white, two-lipped flowers arranged in rings around the stem [Southern Cross University monograph on Lamium album, 2008]. It is native to Europe and Asia, was introduced to North America, and turns up along roadsides, hedgerows, field edges, and disturbed ground.
The genus name traces to the Greek laimos, “throat,” a reference to the flower’s open, tube-like shape. The leaves and flowering tops are the parts used in herbal practice, with most traditional preparations calling specifically for the flowers.
Dead nettle vs. stinging nettle
This is the question most people arrive with, and it matters, because one of these plants will raise welts on your forearm.
| Dead nettle (Lamium album) | Stinging nettle (Urtica dioica) | |
| Family | Mint (Lamiaceae) | Nettle (Urticaceae) |
| Stem | Square, hollow | Square, bristly with stinging hairs |
| Stinging hairs | None | Yes — on stems and leaves |
| Flowers | Showy, white, two-lipped, in whorls | Tiny, greenish, in drooping strings |
| Touch test | Safe to handle | Causes a burning, hive-like rash |
Before it flowers, dead nettle is genuinely easy to mistake for stinging nettle — same rough leaf outline, same upright habit, and the two often grow side by side [Southern Cross University monograph on Lamium album, 2008]. Once the flowers open, there’s no confusion: dead nettle’s white hooded blooms look nothing like the stringy green tassels of a true nettle. If you want the sting-bearing plant instead, that’s a different herb with a different evidence base — see the guide to nettle tea and what the research supports.
The dead nettle in your yard is probably a different species
Here’s a distinction most articles skip. If you’re in the United States and you’ve found a low, sprawling “dead nettle” carpeting your lawn or garden bed in early spring with purple-tinged upper leaves and pink-purple flowers, that’s almost certainly purple deadnettle (Lamium purpureum) — a close cousin, not Lamium album.
Purple deadnettle is an annual, usually under a foot tall, with triangular hairy leaves on stalks and pink to purplish flowers in the upper leaf axils [Washington State University Hortsense fact sheet on purple deadnettle, 2026]. It’s frequently confused with henbit (Lamium amplexicaule), which grows in the same fields at the same time. The reliable tell: henbit’s upper leaves wrap directly around the stem with no stalk, while purple deadnettle’s leaves sit on short stalks and are more triangular with shallow lobes [Purdue University Plant & Pest Diagnostic Laboratory on henbit and purple deadnettle, 2021].
This matters for a practical reason: the traditional herbal literature, the European monographs, and nearly all of the laboratory research are about Lamium album. Findings about one species do not automatically transfer to another, and the two aren’t interchangeable in a tea.
What’s in the plant
Analyses of Lamium album consistently report tannins, mucilage, saponins, flavonoids including rutin, quercetin and kaempferol, and biogenic amines such as histamine, choline and tyramine [Southern Cross University monograph on Lamium album, 2008]. Reviews of the species also describe iridoid glycosides and phenolic acids as characteristic constituents [Journal of Herbmed Pharmacology review of Lamium album, 2019].
Those compounds are a reasonable explanation for why the plant behaves the way it does in a cup or on a cloth. Tannins are astringent, which is why a strong infusion tastes drying and why it was traditionally reached for to tighten tissue and slow oozing. Mucilage is soothing and film-forming. But identifying a plausible mechanism is not the same as demonstrating a clinical effect, and that gap is where most dead nettle content goes wrong.
Traditional uses, graded honestly
| Traditional use | What actually backs it | How to read it |
| Heavy or irregular menstrual bleeding | Long herbal tradition; no gynecological clinical trials have been conducted | Unproven. Abnormal bleeding needs a diagnosis, not a tea |
| Vaginal discharge (leukorrhea) | Traditional use; the flower is approved in Germany for this and for mild inflammation | Traditional-use approval, not trial evidence — and the traditional delivery method is unsafe (see below) |
| Coughs and upper-respiratory catarrh | German Commission E lists this among approved uses for the flowers | Weakest tier of “approved” — based on tradition and plausibility |
| Wounds, bruises, minor skin inflammation | Traditional topical use; some supporting lab work | Plausible, unproven in people |
| Diarrhea | Traditional use of the astringent tannins | Unproven; hydration and medical care matter more |
| Tired, aching feet (footbath) | Folk use only | Harmless and pleasant; expect comfort, not treatment |
Two points anchor this table. Germany’s Commission E — the expert body whose monographs shaped much of modern European herbal practice — approved the flowers of Lamium album while leaving the whole herb unapproved, and for the herb it recorded that the pharmacological properties, pharmacokinetics and toxicology are simply not known [Southern Cross University monograph citing the German Commission E Monographs, 2008]. And despite centuries of use for women’s health specifically, no gynecological trials of the plant have been carried out.
That’s an unusual thing to find at the bottom of a long tradition, and it’s worth saying plainly rather than dressing up.
What the research actually shows
Modern work on Lamium album exists, but almost all of it sits at the laboratory and animal stage. A 2019 review in the Journal of Herbmed Pharmacology surveyed the experimental literature and reported antimicrobial, anti-inflammatory, anticancer, and antidiabetic activity across various models — while framing the plant’s uses as traditional and the research as early [Pourmirzaee Sheikhali Kelayeh et al., Journal of Herbmed Pharmacology, 2019].
A representative example: researchers gave male Wistar rats a Lamium album extract at 100 mg/kg by intraperitoneal injection for a week before inducing a stroke, and found reduced infarct volume, lower neurological deficit scores, and decreased caspase-3 and COX-2 gene expression compared with untreated animals [Khanaki et al., Folia Medica, 2022]. That is a real, peer-reviewed finding. It is also injected extract, in rats, as a pretreatment, at a dose with no human equivalent — which is a long way from a person drinking tea. It tells us the plant is worth studying. It tells us nothing about what a cup of dead nettle tea does for you.
Read any “dead nettle fights cancer” or “dead nettle prevents stroke” headline with that distance in mind.
Eating and brewing dead nettle
Dead nettle leaves are edible and have been eaten cooked, much like spinach; the flowers are edible too [Southern Cross University monograph on Lamium album, 2008]. As a tea, traditional practice is roughly one to two teaspoons of dried flowering tops per cup of boiling water, steeped about 10 minutes. Commission E’s listed daily amount for the flowers is around 3 grams of dried material [Southern Cross University monograph citing the German Commission E Monographs, 2008].
Treat those numbers as tradition, not as a validated dose. Nobody has run the trials that would establish an effective or maximum intake.
If you forage it yourself, a few rules are non-negotiable. Be certain of the identification before anything goes in a pot. Skip roadsides, drainage ditches, dog-walking routes, and any lawn or field that may have been sprayed — the WSU fact sheet lists glyphosate, triclopyr, dicamba and others as standard control products for Lamium in turf and landscape beds [Washington State University Hortsense fact sheet on purple deadnettle, 2026]. Harvest the tender upper growth, rinse it well, and start with a small amount the first time.
Safety, interactions, and who should skip it
Dead nettle has a mild reputation, and the European monograph records no known contraindications, side effects, or drug interactions for the flowers [Southern Cross University monograph citing the German Commission E Monographs, 2008]. Read that carefully: “none known” reflects an absence of systematic study, not a clean bill of health from rigorous safety testing. Very few controlled human studies of this plant exist to detect problems in the first place.
The traditional use to skip entirely. Older herbal texts instruct readers to use a strained dead nettle decoction as a vaginal douche or irrigation for discharge. Do not do this. U.S. health authorities are unambiguous: doctors recommend against douching of any kind, because it disrupts the vagina’s protective bacteria and acidity and is linked to bacterial vaginosis, pelvic inflammatory disease, sexually transmitted infections, trouble getting pregnant, ectopic pregnancy, and preterm birth [Office on Women’s Health guidance on douching, 2025]. Douching also masks the very symptoms a doctor needs to see. Persistent or foul-smelling discharge, itching, burning, or pelvic pain should be evaluated, not rinsed away.
Pregnancy and breastfeeding. There is no reliable safety data for dead nettle in pregnancy or while nursing. Many dietary supplements have simply never been tested in pregnant women, nursing mothers, or children [NCCIH guidance on using dietary supplements wisely, 2019]. Treat dead nettle as off the table in both situations unless your doctor says otherwise.
Medications and medical conditions. No specific drug interactions have been documented, but that is because nobody has looked, not because the plant has been cleared. Talk to a doctor or pharmacist before adding it if you take prescription medication, have a bleeding disorder, or have surgery scheduled — supplements can interact with medications and affect surgical risk [NCCIH guidance on using dietary supplements wisely, 2019].
Product quality. Commercial “dead nettle” extracts, tinctures, and capsules are sold as dietary supplements, which the FDA does not review for safety or effectiveness before they reach shelves; the agency generally acts only after a problem surfaces, and “standardized” on a label does not guarantee consistency [NCCIH on federal regulation of dietary supplements, 2019]. The same caution applies here as to any herbal anti-inflammatory product: check what species and plant part the label actually names, since some products blur Lamium album, Lamium purpureum, and stinging nettle.
Skip it if you: are pregnant, trying to conceive, or breastfeeding; are giving it to a child; have a known allergy to mint-family plants; have unexplained bleeding or discharge that hasn’t been evaluated; or are managing a condition where a delay in proper treatment carries real cost. It is also not the right tool for herbs with documented toxicity risks — a plant being “gentle” is specific to that plant, and other traditional women’s herbs such as common rue carry serious cautions that dead nettle does not.
When to see a doctor instead
Some of the problems dead nettle was traditionally used for are exactly the problems that need a doctor’s eyes.
Make an appointment for bleeding between periods, periods that soak through a pad or tampon every hour, bleeding after sex, any bleeding after menopause, or a discharge that’s new, foul-smelling, green or gray, or comes with itching or pain. A blood-staunching herb should never be used to quiet unexplained bleeding before the cause is known.
Also see a doctor for a wound that’s red, warm, swollen, streaking, or oozing pus; a cough lasting more than three weeks or bringing up blood; and diarrhea that persists beyond a couple of days or comes with fever, blood, or signs of dehydration.
Go to an emergency room or call 911 for heavy bleeding you can’t control, severe abdominal or pelvic pain, fainting, a fever with confusion, or trouble breathing.

Frequently Asked Questions
Is the dead nettle plant safe to touch?
Yes. Dead nettle has no stinging hairs, which is where the name comes from. You can handle the leaves and flowers bare-handed without the burning rash a stinging nettle causes.
Is dead nettle the same as purple deadnettle?
No — they’re relatives, not the same plant. White dead nettle is Lamium album, a taller perennial with white flowers. Purple deadnettle is Lamium purpureum, a low-growing annual with purple-tinted upper leaves and pink-purple flowers, and it’s the one most Americans find in their lawns in early spring. Nearly all the herbal literature and research refers to Lamium album.
Can you eat dead nettle?
The leaves and flowers are edible, and the leaves have traditionally been cooked like spinach. Identify the plant with confidence first, and don’t harvest from roadsides or anywhere that may have been sprayed with herbicide.
Does dead nettle tea help with heavy periods?
There’s a long tradition of using it that way, but no clinical trials in women have tested it, so there’s no evidence it works. Heavy or irregular bleeding has many possible causes — fibroids, polyps, thyroid problems, bleeding disorders, hormonal changes — and it deserves a diagnosis rather than a home remedy.
Are there side effects?
No systematic side-effect profile has been established, largely because the plant hasn’t been studied that way in people. Allergic reactions are possible with any plant. The one clear harm is the traditional douching instruction, which health authorities advise against regardless of what’s in the liquid.
Is dead nettle the same as stinging nettle for supplements?
No, and this trips people up when shopping. Most products labeled “nettle” are stinging nettle (Urtica dioica), a different plant family with a different evidence base. Check the Latin name on the label.
