Identification and mix-ups
Shrub or small tree with corky, pale grey-brown bark and pithy branches. Leaves pinnate with 5-7 elliptic to ovate, serrate leaflets with a mildly unpleasant odour when crushed. Flowers white to cream, small, five-petalled, in flat-topped cymes (10-20 cm diameter) with a strong sweet scent. Fruits round, purple-black drupelets borne in pendant clusters.
Possible mix-ups and risks
The most serious confusion risk is with dwarf elder (Sambucus ebulus), which is a perennial herb (not a woody shrub) growing to about 1.5 m, bearing stipules at the leaf bases and similarly dark fruits but with reddish pedicels, and with more strongly malodorous leaves. Dwarf elder is toxic. A less dangerous confusion is with red elder (Sambucus racemosa), which has oval erect panicles (not flat-topped cymes), pale brownish pith, and red fruits.

Processing methods on this herb card
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
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
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
Microbial processing (fermentation) of plant material for drinks or foods.
Full method description (from the catalogue)
Fermentation changes sugars, flavour, and microbial composition (e.g. herbal ferments, oxymels combining honey and vinegar per tradition). Hygiene, temperature, and time are critical for a safe outcome.
Home ferments should not smell “rotten”; when in doubt, discard.
Traditional context for this method: yes·Scientific context for this method: no
Sweet alcoholic macerate with herbs; sugar and ethanol drive the outcome.
Full method description (from the catalogue)
A liqueur combines herbs, spirit, and sweetener into a strongly aromatic mixture. Home batches differ from commercial products in law and in how strength is controlled.
Follow the recipe for dosing and storage; maceration time changes colour and flavour.
Traditional context for this method: yes·Scientific context for this method: no

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.
Meta-analyses of randomised trials (roughly 180 participants overall) report elderberry extracts may shorten or ease upper respiratory symptoms versus placebo; products and dosing schedules differed between studies.
Moderate strength of evidenceMeta-analysisYear: 2019Limitations: Small pooled numbers; heterogeneous syrups and capsules; unripe fruit toxicity and drug interactions are not fully covered here; pregnancy and paediatric use need individual review.

A brief overview of five clinical studies (adults, short-term use of commercial berry preparations) suggests possible shortening or easing of symptoms in viral respiratory infections when started within 48 h; reliable data are lacking for COVID-19 and for pregnancy.
Preliminary findingsReview studyYear: 2020Limitations: A narrative synthesis without a new meta-analysis; study selection and commercial products limit the transfer from flower tea vs. berry extract; unripe parts of the plant remain a risk.
