# Sambucus

Sambucus is a genus of between 20-30 species of flowering plants in the family Adoxaceae. The various species are commonly referred to as elder, with the flowers as elderflower, and the fruit as elderberry.

## Description

Elders are mostly fast-growing shrubs or small trees 3–10 m (9.8–32.8 ft) (rarely to 14 m (46 ft)) tall, with a few species being herbaceous plants 1–2 m (3 ft 3 in – 6 ft 7 in) tall. The oppositely arranged leaves are pinnate with 5–9 leaflets (or, rarely, 3 or 11). Each leaf is 5–30 centimetres (2–12 in) long, and the leaflets have serrated margins. They bear large clusters of small white or cream-coloured flowers in late spring or early summer; these are followed by clusters of small berries that are green when immature, ripening black, blue-black, or red (rarely yellow or white).

## Taxonomy

The taxonomy of the genus Sambucus L., originally described by Carl Linnaeus and hence its botanical authority, has been complicated by its wide geographical distribution and morphological diversity. This has led to overdescription of the species and infraspecific taxa (subspecies, varieties or forms).
The genus was formerly placed in the honeysuckle family Caprifoliaceae, but was reclassified in the moschatel family Adoxaceae due to genetic and morphological comparisons to plants in the genus Adoxa.
Species currently accepted by Plants of the World Online in this genus are:
* Sambucus adnata Wall. ex DC.
* Sambucus africana Standl.
* Sambucus australasica (Lindl.) Fritsch
* Sambucus australis Cham. & Schltdl.
* Sambucus canadensis L.
* Sambucus cerulea Raf.
* Sambucus ebulus L.
* Sambucus gaudichaudiana DC.
* Sambucus javanica Reinw. ex Blume
* Sambucus kamtschatica E.L.Wolf
* Sambucus lanceolata R.Br.
* Sambucus mexicana C.Presl ex DC.
* Sambucus nigra L.
* Sambucus palmensis Link
* Sambucus pendula Nakai
* Sambucus peruviana Kunth
* Sambucus racemosa L.
* Sambucus sibirica Nakai
* Sambucus sieboldiana (Miq.) Graebn.
* Sambucus × strumpfii Gutte
* Sambucus tigranii Troitsky

### Etymology

The name comes from the Ancient Greek word σαμβύκη ( ‹See RfD› sambū́kē), an ancient wind instrument, about the removal of pith from the twigs to make whistles.

## Distribution and habitat

The genus occurs in temperate to subtropical regions of the world. More widespread in the Northern Hemisphere, its Southern Hemisphere occurrence is restricted to parts of Australasia and South America. Many species are widely cultivated for their ornamental leaves, flowers, and fruit.
Elder commonly grows near farms and homesteads. It is a nitrogen-tolerant plant and thus is often found near places of organic waste disposal. Elders are often grown as a hedgerow plant in Britain since they take very fast, can be bent into shape easily, and grow quite profusely, thus having gained the reputation of being an "instant hedge". It is not generally affected by soil type or pH level and will grow virtually anywhere sufficient sunlight is available.

## Ecology

The berries are consumed by birds and mammals. In Northern California, elderberries are eaten by migrating band-tailed pigeons. Elders are used as food plants by the larvae of some Lepidoptera species including brown-tail, buff ermine, dot moth, emperor moth, engrailed moth, swallow-tailed moth and the V-pug. The crushed foliage and immature fruit have a strong fetid smell. Valley elderberry longhorn beetles in California are very often found around red or blue elderberry bushes. Females lay their eggs on the bark. Strong-scented flowers in wild populations of European elder (S. nigra) attract numerous, minute flower thrips which may contribute to the transfer of pollen between inflorescences.

## Cultivation

Traditional uses of Sambucus involved berries, seeds, leaves, and flowers or component extracts. Ornamental varieties of Sambucus are grown in gardens for their showy flowers, fruits and lacy foliage which support habitat for wildlife. Of the many native species, three are used as ornamentals: S. canadensis, S. nigra, and S. racemosa.

## Toxicity

The uncooked berries and other parts of plants from this genus are poisonous. Leaves, twigs, branches, seeds, roots, flowers, and berries of Sambucus plants produce cyanogenic glycosides, which have toxic properties. Ingesting a sufficient quantity of cyanogenic glycosides from berry juice, flower tea, or beverages made from fresh leaves, branches, and fruit has been shown to cause illness, including nausea, vomiting, abdominal cramps, diarrhea, and weakness. In August 1983, a group of 25 people in Monterey County, California, became ill after ingesting elderberry juice pressed from fresh, uncooked S. mexicana berries, leaves, and stems. The concentration of cyanogenic glycosides is higher in tea made from flowers (or leaves) than from the berries.
The seeds of Sambucus racemosa are reported to be poisonous and may cause vomiting or diarrhea.

## Uses

The cooked berries (pulp and skin) of most species of Sambucus are edible.

### Nutrition

Raw elderberries are 80% water, 18% carbohydrates, and less than 1% each of protein and fat. In a 100-gram (3+1⁄2 oz) amount, elderberries supply 305 kilojoules (73 kcal) of food energy and are a rich source of vitamin C, providing 43% of the Daily Value (DV). Elderberries also have moderate contents of vitamin B$_6$ (18% DV) and iron (12% DV), with no other nutrients in significant content.

### Chemistry

Sambucus fruit is rich in anthocyanidins that combine to give elderberry juice an intense blue-purple colour that turns reddish on dilution with water.

### Dietary supplement

Elderberry fruit or flowers are used as dietary supplements to prevent or provide relief from minor diseases, such as flu, colds, constipation, and other conditions, served as a tea, extract or in a capsule. The use of elderberry supplements increased early in the COVID-19 pandemic. There is insufficient research to establish its effectiveness for such uses, or its safety profile. The raw or unripe fruit of S. nigra or its extracts may contain a cyanogenic glycoside that is potentially toxic.

### Traditional medicine

Although practitioners of traditional medicine have used elderberries over centuries, there is little high-quality clinical evidence that such practices provide benefits.

### Pigments

The pigments are used as colourants in various products, and "elderberry juice color" is listed by the US Food and Drug Administration as allowable in certified organic food products. In Japan, elderberry juice is listed as an approved "natural colour additive" under the Food and Sanitation Law. Fibres can be dyed with elderberry juice (using alum as a mordant) to give a "muted purple" shade.

### Other

The berry of S. racemosa can be made into wine. The flowers of S. nigra are used to produce elderflower cordial. St-Germain, a French liqueur, is made from elderflowers. Hallands Fläder, a Swedish akvavit, is flavoured with elderflowers.
Hollowed elderberry twigs have traditionally been used as spiles to tap maple trees for syrup. Additionally, they have been hollowed out and used as flutes, blowguns, and syringes. In addition, the elderberry twigs and fruit are employed in creating dyes for basketry. These stems are dyed a very deep black by soaking them in a wash made from the berry stems of the elderberry.
The pith of elder has been used by watchmakers for cleaning tools before intricate work.

## In culture

Folklore related to elder trees is extensive and can vary according to region. In some traditions, the elder tree is thought to ward off evil and give protection from witches, while other beliefs say that witches often congregate under the plant, especially when it is full of fruit. If an elder tree was cut down, a spirit known as the Elder Mother would be released and take her revenge. The tree could only safely be cut while chanting a rhyme to the Elder Mother. Romani people believe burning elder wood brings bad luck.
A wand made from the branch of an elder tree plays a pivotal role in the final book of the Harry Potter series, which was almost named Harry Potter and the Elder Wand.
