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 in Zingiberaceae reaching 2–4 m, with leaf-shoots arising from a stout rhizome in clumps of up to about 20. Leaves alternate, two-ranked, linear-lanceolate (40–60 cm), dark green and paler beneath. Flowers white to lilac (one petal streaked violet) on a loose spike (30–60 cm) arising near ground level. Fruit a three-sided yellow-green capsule (1–2 cm) with 15–20 aromatic black-brown seeds; the aroma is warm and sweetly citrusy.

Possible mix-ups and risks

The most common lookalike (and deliberate substitute) is black cardamom (Amomum subulatum, syn. Lanxangia subulata), a non-toxic spice. It differs in its large, dark-brown capsules with a smoky, camphoraceous-resinous aroma, versus the small light-green capsules and sweet aroma of true cardamom.

Similar herbs

  • Ginger

    Cardamom and ginger belong to the same ginger family, but a different part is harvested: seed pods for cardamom, the rhizome for ginger. The scents are not confused; the two meet in masala chai.

Harvest

  • FruitOctober–February

    winter

    Region: India

    Notes: Green unripe pods before they open fully; dried in the shade.

Storage

  • Airtight storage(Fruit)

    Whole pods keep a year in an airtight jar; seeds shelled from the pods weeks, ground cardamom loses its scent within days — grind just before use.

    Light:
    Out of light; the green colour fades in light.
    Moisture:
    Protect from moisture; pods pick up foreign smells.

Processing methods on this herb card

  • Culinary use(Fruit)Suitability: High suitability

    Cooking, baking, seasoning as food — general category without therapeutic claims.

    Full method description (from the catalogue)

    Culinary use covers herbs as ingredients in dishes, drinks, or spice mixes. This overview does not evaluate medicinal effects — only reminds you about species intent, allergies, and heat treatment where needed (e.g. some fruits or plant parts).

    Combining with alcohol, sugar, or long cooking changes outcomes; verify culinary sources.

  • Herbal infusion (tea)(Fruit)Suitability: Medium suitability

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

    Full method description (from the catalogue)

    Here, herbal tea is prepared as an infusion: pour freshly boiling water over dried herbs or a herbal blend and steep for at least 5 minutes. BfR gives this as a hygiene rule, not a medicinal dose. Follow the specific product instructions, including a longer steeping time when stated. This rule for herbal infusions is not a general preparation guide for true tea (Camellia sinensis). 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: yes

  • Essential oil(Fruit)Suitability: Low suitability

    A concentrated aromatic plant product; use depends on the specific product.

    Full method description (from the catalogue)

    Essential oil is a concentrated plant product obtained, for example, by steam distillation or pressing. A general drop count or dilution ratio does not establish safe use.

    Choose a finished product intended for your purpose and follow its directions. Do not apply it to skin or swallow it unless the manufacturer explicitly allows that use. This overview is not a recipe for home dilution.

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

    The essential oil is steam-distilled from the seeds industrially; it is not made at home. Do not take internally; on the skin only diluted in a carrier oil.

  • Cardamom in coffee — a gesture of hospitality from Malabar to Arabia

    General

    Traditional useFolk useRitual

    From the Malabar Coast cardamom travelled the trade routes to Persia and Arabia, where it became part of hospitality coffee (gahwa): a crushed pod in the spout of the pot still signals that a guest is welcome. In India the pods are chewed after meals for fresh breath and added to temple sweets (prasad). A record of cultural tradition.

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.
