  • Generally recognised as safe. Often a common herb with reasonable harvest and use; still read the specific warnings on the card.
  • Information. Primarily informational — details in the text and warnings below matter most.
  • Caution. Needs extra care (dose, duration, sensitive groups, interactions).
  • Risky. Significant risks — verify sources, contraindications and professional guidance.
  • Not for home experimentation. Not suitable to experiment with at home without knowledge and certainty.
  • High risk for internal use. Particular risk with internal use (e.g. alkaloids); avoid prolonged or irresponsible dosing.
  • Not specified. Level not filled in yet — rely on individual warnings and links below.

Processing methods on this herb card

  • Herbal infusion (tea)(Leaf)Suitability: High suitability

    Infusion or brief extraction in hot water; usually without long boiling.

    Full method description (from the catalogue)

    In the narrow sense, “tea” often means an infusion: you pour water just off the boil over the dried plant matter and let it steep for a few minutes. Temperature, steep time, and the herb-to-water ratio change both flavour and what dissolves into the liquid.

    Compared with a decoction, heat exposure is shorter and gentler; tender leaves and flowers are often better as an infusion than with prolonged simmering. For each herb, always follow the plant card for suitable plant part, preparation, and safety notes — general rules never replace species-level judgement.

    Traditional context for this method: yes·Scientific context for this method: no

    Procedure (recipe)

    White dead-nettle infusion

    About 10 min · Difficulty: Beginner

    1. Use 1–2 teaspoons of dried flowering tops with leaves per cup.
    2. Pour boiling water, cover, and steep 8–10 minutes.
    3. Strain — mild flavour; harvest only after confident ID.

    Do not confuse with other Lamium species — confident field identification is essential.

    Why this way (extraction / behaviour of constituents)

    Home preparation following this recipe is mainly educational and cultural in intent; it does not automatically match the extraction or safety profile of registered medicines or standardized extracts. Check specific effects, drug interactions, and contraindications on the herb card and with a clinician if you use medication.

    Extra literature for the recipe

  • Honey macerate(Leaf)Suitability: High suitability

    Macerating plant material in honey (a honey conserve).

    Full method description (from the catalogue)

    Honey as a maceration medium creates a viscous mixture with its own biochemistry: water activity, acidity, and enzymes influence shelf life and flavour. Traditionally it is used with delicate flowers or herbs when you want aroma bound into honey.

    Infant botulism guidance for honey and honey safety in general sit outside a single herb page; maceration time, ratios, and storage must follow a vetted recipe and source, not this general overview alone.

    Traditional context for this method: yes·Scientific context for this method: no

    Procedure (recipe)

    White dead-nettle honey

    About 30 min · Difficulty: Beginner

    1. Fill a jar about one third with dried leafy tops and pour honey over them.
    2. Press gently with a spoon, close, and macerate 2–3 weeks in a warm shady place.
    3. Strain through cloth; harvest only with confident species identification.

    Maceration takes weeks; do not confuse with other dead-nettles.

    Why this way (extraction / behaviour of constituents)

    Home preparation following this recipe is mainly educational and cultural; it should not be assumed to match the extractive or safety profile of registered medicines or standardized extracts. Check specific effects, drug interactions, and contraindications on the herb card and with your clinician if you use prescription drugs.

    Extra literature for the recipe

  • Syrup(Leaf)Suitability: Medium suitability

    Decoction or infusion with sweetener and reduction; shelf life depends on sugar and storage.

    Full method description (from the catalogue)

    Syrups combine a herbal base with sugar or honey and often a short boil to concentrate and improve hygiene. Preservation depends strongly on water content, sugar level, and bottling practice.

    Home syrups may fall under food rules; store in the fridge after opening per recipe.

    Traditional context for this method: yes·Scientific context for this method: no

    Procedure (recipe)

    White dead-nettle syrup

    About 45 min · Difficulty: Beginner

    1. Simmer 2–3 tsp dried leafy tops in 400 ml water for about 10 minutes, then strain.
    2. Stir in honey or sugar with gentle warming.
    3. Store chilled; harvest only with confident species identification.

    Traditional useFolk useHerbal lore

    White dead-nettle favours richer edges and gardens; white whorled flowers suggest insects and a summer day. The layer is landscape and garden aesthetics — any tea tradition still demands confident species ID.

Scientific notes

Each claim lists a study type and a source (URL or DOI) where available. Dose notes from the literature are informational only.

How to read evidence strength and study type labels

Labels summarise how the catalogue entry is tagged — they are not a medical verdict on efficacy. For every row, read the summary, limitations and source link.

Evidence strength

Evidence level not specified
The author did not grade the record; judge from the summary, limitations and source link.
Narrative / orientational literature
Descriptive or expert literature without controlled group comparison — context rather than proof of effect.
Weak evidence
Study or conclusion with major methodological limits; treat only as a pointer for further reading.
Preliminary findings
First or smaller studies — interesting direction, not the final word on efficacy or safety.
Moderate strength of evidence
Moderate strength by study design; sample and context limits still apply.
Stronger evidence
Stronger design or consistency of results within the study’s stated limits.
Review article
A review summarises multiple sources; quality depends on review method and field.

Study type

Narrative / expert text
Expert text or overview without a classical study design.
In vitro study
Cell culture or test-tube experiment — does not show an effect in the body.
Animal study
Animal model — transfer to humans is not automatic.
Observational study
Observing groups without random treatment assignment; confounding is possible.
Clinical trial
Human clinical trial; sample size and control group matter.
Randomised controlled trial
Randomised controlled trials are among the stronger designs when well conducted.
Review study
A review aggregates multiple papers — quality depends on selection rules.
Systematic review
Systematic review with explicit search and selection methodology.
Meta-analysis
Statistical pooling of studies; outcome depends on input data and heterogeneity.
Regulatory assessment / monograph (EMA, WHO…)
Regulatory body summary for a herbal product — different context from a single RCT; often about products, not home tea.
Expert monograph (herbal preparations)
Structured literature summary for a plant or drug — quality depends on author and edition year.

  • White dead-nettle is comparatively little represented in modern clinical series; traditional use overlaps with related Lamiaceae herbs and must be separated from firm efficacy claims.

    Evidence level not specifiedNarrative / expert text

    Limitations: Species identification matters; confusion with stinging nettle or other mints changes risk; robust RCT evidence for specific indications is limited.

Interactions / medicines
Possible effect on medicines or concurrent treatment — check sources and a professional.
Raw plant parts
Raw, unripe or poorly prepared plant parts can be dangerous.
Toxins and regulation
Toxic constituents or regulated compounds (e.g. in distillates).
Contact with the plant
Skin or mucosa irritation from contact with fresh plant or sap.
Allergy
Allergic reactions, often linked to family sensitisation.
Harvesting and contamination
Contamination, species mix-ups or harvesting from unsuitable places.
