Overview
Red Elderberry is a fast-growing shrub or small tree found across North America, Europe, and Asia, producing large clusters of creamy-white flowers followed by bright red berries. It is closely related to the more commonly used Black Elderberry (Sambucus nigra) but is distinct in important ways — most notably, the raw red berries contain toxic cyanogenic glycosides and should never be eaten raw. However, the flowers and properly prepared bark have a long history of medicinal use in Native American and European herbal traditions. The flowers share many of the immune-supporting and anti-inflammatory properties of black elderflower, while the bark has been used as a powerful emetic and purgative. Red Elderberry requires careful preparation and respect for its toxicity profile.
Traditional Use
Red Elderberry was used extensively by Pacific Northwest and other North American Native American tribes, though with careful knowledge of its toxicity. The Quinault used the bark as a powerful purgative and emetic for serious illness. The Nlaka'pamux used the flowers for colds and respiratory infections. The Haida used bark preparations for venereal diseases and as a strong laxative. The Saanich used flower tea for fevers and colds. The Bella Coola used the bark for skin conditions. In European herbal traditions, red elderberry (Sambucus racemosa) was used similarly to black elder — the flowers for colds, fevers, and respiratory complaints, and the bark as a strong purgative. Traditional knowledge consistently emphasized that the raw berries must never be eaten and that bark preparations require careful dosing. Today, red elderberry is used primarily for its flowers (similar to black elderflower) for immune support and respiratory complaints, while bark use is reserved for experienced practitioners.
Key Active Compounds
Sambunigrin & Cyanogenic Glycosides (Berries — TOXIC RAW)
The raw red berries contain cyanogenic glycosides that release hydrogen cyanide when metabolized. These compounds are destroyed by thorough cooking. This is why raw red elderberries must never be consumed — cooking is essential to render them safe.
Flavonoids (Rutin, Quercetin, Kaempferol) — Flowers
The flowers are rich in antioxidant flavonoids that provide anti-inflammatory, antiviral, and immune-modulating effects. These are the same beneficial compounds found in black elderflower and contribute to the flowers' effectiveness for colds and respiratory infections.
Triterpenes (Alpha & Beta-Amyrin, Ursolic Acid) — Bark
Anti-inflammatory and antimicrobial triterpenes found in the bark that contribute to its therapeutic properties. Ursolic acid has documented anti-inflammatory, antiviral, and hepatoprotective effects.
Mucilage & Tannins — Flowers
Soothing mucilage and astringent tannins in the flowers that coat and protect irritated mucous membranes in the respiratory tract, contributing to the flowers' effectiveness for coughs and sore throats.
Sambucine & Alkaloids — Bark
Alkaloids in the bark responsible for its powerful emetic and purgative effects. These compounds require careful dosing and are the reason bark preparations should only be used under experienced guidance.
Evidence-Based Benefits
Immune Support & Cold/Flu Relief (Flowers)
Moderate evidenceRed elderberry flowers share the immune-supporting and antiviral properties of black elderflower. The flavonoids and mucilage support immune function, reduce inflammation in the respiratory tract, and have demonstrated antiviral activity in laboratory studies. Flower tea is a traditional remedy for colds, flu, and fever across multiple cultures.
Respiratory Support (Flowers)
Traditional useThe flowers act as a diaphoretic (promotes sweating to break fevers), expectorant (loosens mucus), and anti-inflammatory for the respiratory tract. Traditionally used for colds, bronchitis, sinusitis, and hay fever. The mucilage soothes irritated airways and the flavonoids reduce inflammation.
Fever Reduction (Flowers)
Traditional useRed elderberry flowers have been used across cultures as a diaphoretic to promote sweating and reduce fever. The flavonoids and volatile compounds support the body's natural fever-resolution process. Traditionally combined with peppermint and yarrow for fever management.
Skin Conditions (Topical — Flowers & Bark)
Traditional useTopical preparations of red elderberry flowers and bark have been used for skin conditions including eczema, rashes, and minor wounds. The tannins and anti-inflammatory compounds provide astringent and soothing effects on irritated skin.
Common Preparation Methods
Red Elderflower Tea
Add 1-2 teaspoons of dried red elderberry flowers to 8 oz of hot water (not boiling). Steep for 10 minutes, covered. Strain and drink. The tea has a pleasant, sweet, muscat-like flavor similar to black elderflower.

Red Elderflower Tincture
Use a 1:5 tincture of dried red elderberry flowers in 25% alcohol. Take 2-4 ml up to three times daily in water. Tincture preserves the flavonoids and volatile compounds effectively.
Dosage: 2-4 ml, 2-3 times daily.Flowers only — do not make tincture from raw berries or bark for home use. Effective for immune support and respiratory complaints.
Elderflower Infused Honey
Fill a jar with fresh or dried red elderberry flowers. Cover completely with raw honey. Seal and leave in a warm place for 2-4 weeks, stirring occasionally. Strain out flowers. Use infused honey in tea, on toast, or take by the teaspoon.
Dosage: 1-2 teaspoons daily for immune support or sore throat.Combines the benefits of elderflower and honey. Pleasant-tasting and easy to use. Store in a cool, dark place. Use within 6 months.
Topical Elderflower Wash
