**Brief introduction:**
Elder is a deciduous shrub or small tree native to Europe and parts of North America, depending on species. The European black elder produces fragrant clusters of creamy white flowers followed by dark purple-black berries. Elder has an unusually rich place in European folklore, where the tree was associated with household spirits, protection, death, regeneration, and the boundary between the domestic world and the wild. Its flowers and properly prepared ripe berries have long been used as foods and medicines, while other portions of the plant require considerably greater caution.
**Traditional uses:**
* Elderflower preparations for feverish colds and seasonal respiratory complaints
* Elderberry preparations for colds and influenza-like illness
* Elderflower as a mild diaphoretic to encourage perspiration
* Elderflower preparations for irritated eyes and skin
* Elderberry as a nutritive and medicinal food during winter
**Historical use:**
* European folk medicine used elderflower for fevers, colds, and respiratory complaints
* Elderberries were cooked into syrups, wines, preserves, and medicinal preparations
* Elderflower water was historically used as a skin and cosmetic preparation
* Leaves and bark appeared in older European herbal medicine but are considerably less suitable for internal use because of their toxicity
* Elder was surrounded by extensive European folklore, including traditions that the tree should not be cut without permission from the spirit or supernatural guardian associated with it
**Parts used and method of use:**
* Flowers
* Fully ripe berries
Used as:
* Elderflower infusion
* Elderberry syrup or decoction
* Cooked elderberry preserves or wine
* Elderflower water or diluted topical preparation
**Use in healing (modern herbal practice):**
* Supportive treatment for uncomplicated upper-respiratory infections
* Symptomatic support during colds
* Traditional support for fever and perspiration
* Elderflower preparations for minor inflammatory skin conditions
* Elderberry preparations as a source of anthocyanins and other antioxidant compounds
**Pharmacology and biochemistry:**
* Anthocyanins, particularly cyanidin glycosides
* Flavonoids, including rutin and quercetin derivatives
* Phenolic acids and other polyphenols
Mechanisms:
* Anthocyanins and flavonoids provide antioxidant activity and may modulate inflammatory pathways
* Elderberry extracts demonstrate antiviral activity against some viruses in laboratory studies
* Elderflower constituents may influence inflammatory mediators and mucus secretion
Overall profile: Elderflower and properly prepared ripe elderberries are traditional medicinal foods with antioxidant and anti-inflammatory constituents. Evidence for elderberry in reducing the duration or severity of upper-respiratory illness is suggestive but not definitive. Elder should be distinguished carefully from its toxic unripe berries, leaves, stems, and bark.
**Common dosage:**
* Elderflower infusion: 2–5 g dried flowers per cup of hot water, up to 3 times daily
* Elderberry syrup: approximately 15 mL up to 4 times daily, depending on preparation
* Dried elderberry: Only after appropriate cooking; follow the preparation's labelled dose
* Elderflower tincture: 2–4 mL of a typical 1:5 tincture, up to 3 times daily
**Safety factors (including side effects):**
* Only fully ripe berries that have been properly cooked should be used internally
* Raw or unripe berries, leaves, stems, and bark can contain cyanogenic glycosides and may cause nausea, vomiting, diarrhea, dizziness, or more serious toxicity
* Do not consume homemade preparations containing leaves, stems, bark, or unripe fruit
* Allergic reactions to elderflower or elderberry are possible
* Long-term medicinal use has not been studied as extensively as culinary use; use standardized preparations when possible
**First aid / adverse reaction response:**
* Nausea, vomiting, or diarrhea after elderberry: Stop use, hydrate if able, and seek medical advice if symptoms are significant or persistent
* Suspected ingestion of raw/unripe berries, leaves, stems, or bark: Contact a poison centre promptly for individualized advice
* Difficulty breathing, facial swelling, or widespread hives: Seek emergency medical attention for possible anaphylaxis
* Severe dizziness, weakness, confusion, or persistent vomiting: Seek urgent medical evaluation
**Drug interactions:**
* Elderberry's effects on immune and inflammatory pathways could theoretically interact with immunosuppressive therapy
* Elderberry preparations may theoretically have additive effects with medications affecting blood glucose
* Diuretic effects are traditionally attributed to elderflower, creating a theoretical interaction with diuretic medications
* General interaction considerations: Evidence for clinically significant interactions is limited; people taking prescription medications should use concentrated elder preparations cautiously
**Horticultural requirements:**
* USDA / Canadian zone: Zones 3–9, depending on species
* Soil pH: 5.5–7.5
* Light requirements: Full sun / partial shade
* Moisture: Moist, fertile, well-drained soil; tolerates periodically wet conditions better than many shrubs
* Other notes (growth habit, harvest timing, etc.):
* Growth habit: Vigorous deciduous shrub or small multi-stemmed tree, commonly 2–6 m tall
* Flowering/fruiting: Creamy-white flower clusters appear in late spring or early summer, followed by berries in summer
* Harvest timing: Flowers are gathered when freshly opened; ripe berries are harvested when fully dark and mature
* Habitat: Woodland edges, hedgerows, stream margins, disturbed ground, and gardens
* Propagation/cultivation notes: Easily propagated from hardwood cuttings or seed; spreads readily under favorable conditions and can become a substantial shrub
**Sampling of clinical reports / studies:**
* Small randomized clinical trials of standardized elderberry preparations have investigated their effects on upper-respiratory symptoms, with some reporting reduced symptom duration or severity
* Pharmacological studies demonstrate antioxidant, anti-inflammatory, and antiviral activity in elderberry extracts
* Phytochemical studies identify anthocyanins, flavonoids, and phenolic acids as important constituents
* Ethnobotanical and historical evidence documents extensive European medicinal and food use of elder, together with a particularly rich body of folklore concerning the tree
* Overall assessment of evidence: Elderflower and properly prepared elderberry have substantial traditional use and promising pharmacological evidence, with limited but suggestive clinical evidence for respiratory illness. Toxicity from improperly prepared plant material is an important distinction in any medicinal use of elder.
