Sambucus
Sambucus is a genus of flowering plants in the family Adoxaceae. The various species are commonly called elder or elderberry. The genus was formerly placed in the honeysuckle family, Caprifoliaceae, but was reclassified as Adoxaceae due to genetic and morphological comparisons to plants in the genus "Adoxa". Description. The oppositely arranged leaves are pinnate with 5–9 leaflets (or, rarely, 3 or 11). Each leaf is long, and the leaflets have serrated margins. They bear large clusters of small white or cream-colored flowers in late spring; these are followed by clusters of small black, blue-black, or red berries  (rarely yellow or white). Color. Sambucus fruit is rich in anthocyanidins that combine to give elderberry juice an intense blue-purple coloration that turns reddish on dilution with water. These pigments are used as colorants in various products, and "elderberry juice color" is listed by the US FDA as allowable in certified organic food products. In Japan, elderberry juice is listed as an approved "natural color additive" under the Food and Sanitation Law. Fibers can be dyed with elderberry juice (using alum as a mordant) to give . Toxicity. Although the cooked berries (pulp and skin) of most species of "Sambucus  are edible, 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 suddenly ill by ingesting elderberry juice pressed from fresh, uncooked "Sambucus mexicana" berries, leaves, and stems. The density of  cyanogenic glycosides is higher in tea made from flowers (or leaves) than from the berries. The seeds of "Sambucus callicarpa" are reported to be poisonous and may cause vomiting or diarrhea. Taxonomy. The taxonomy of the genus "Sambucus" , 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 name comes from the Greek word "sambuce", an ancient wind instrument, about the removal of pith from the twigs to make whistles. Species recognized in  this genus are: 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. Habitat. Elder commonly grows near farms and homesteads. It is a nitrogen-dependent plant and thus is generally 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 virtually grow anywhere sufficient sunlight is available. Ecology. In Northern California, elderberries are a food for 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. The pith of elder has been used by watchmakers for cleaning tools before intricate work. 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. nigra", "S. canadensis" and "S. racemosa". Uses. Nutrition. Raw elderberries are 80% water, 18% carbohydrates, and less than 1% each of protein and fat (table). In a amount, elderberries supply 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 B6 (18% DV) and iron (12% DV), with no other nutrients in significant content. 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 elderberry over centuries, there is no high-quality clinical evidence that such practices provide any benefit. Other. The flowers of "Sambucus 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. The fruit of "S. callicarpa" is eaten by birds and mammals. It is inedible to humans when raw but can be made into wine. 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. In popular 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. Made from the branch of an elder tree, the Elder Wand plays a pivotal role in the final book of the "Harry Potter" series, which was nearly named "Harry Potter and the Elder Wand" before author J. K. Rowling decided on "Harry Potter and the Deathly Hallows". Elton John's 1973 album "Don't Shoot  Me I'm Only the Piano Player" features a song titled "Elderberry Wine". In "Monty Python and the Holy Grail", John Cleese as the French Taunter tells the knights of Camelot, "Your mother was a hamster, and your father smelt of elderberries."
