What the safety levels mean (expand legend)
  • 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.

Identification and mix-ups

Perennial herb with a basal rosette of broad, ovate to elliptic leaves bearing 5-9 prominent parallel veins, gradually or abruptly contracted at the base into a petiole, with entire or shallowly toothed margins. Scapes cylindrical, without conspicuous ridges. Spike slender and longer relative to the scape than in ribwort plantain, with small greenish-brown flowers and, at full anthesis, conspicuous purple stamens.

Possible mix-ups and risks

Most commonly confused with ribwort plantain (Plantago lanceolata), which has distinctly lanceolate (narrow, long) leaves with only 3-5 veins converging to a narrow tip, a strongly ridged scape, and a denser cylindrical spike with white stamens. Both species occupy similar habitats and are regularly confused in the field. The key distinguishing character is leaf blade shape: broadly ovate-elliptic with a distinct petiole (P. major) versus lanceolate without a distinct petiole (P. lanceolata).

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.

  • Salve / ointment(Leaf)Suitability: Medium suitability

    Solid base (wax, fat) with herbal extract or macerate; usually topical.

    Full method description (from the catalogue)

    Salves combine extracted or finely ground herb with fat and often beeswax. Consistency depends on ratios; protective or emollient salves aim for a skin film with slow release.

    Clean work reduces microbial contamination; refrigerated storage may extend life per recipe.

  • Poultice / compress(Leaf)Suitability: High suitability

    Liquid or paste on the skin, often through a thin cloth.

    Full method description (from the catalogue)

    A compress applies moist warm or cool material to the skin directly or through fabric. Duration and temperature are key — too hot can burn; too long can macerate the skin.

    Use clean textiles and watch skin reaction during the first minutes.

  • Balm(Leaf)Suitability: High suitability

    Thicker oily blend with more aromatic components; the term varies in practice.

    Full method description (from the catalogue)

    A balm is often perceived as thicker than a light salve, sometimes with richer scent or a firmer skin feel. Commercial and DIY meanings differ — always read ingredients and intended use (lips, elbows, massage).

    For DIY work, watch emulsion stability and preservation per recipe.

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.
