What is elderberry?

Elderberries come from different varieties of the Adoxaceae Sambucus tree. The most common of these is the European elderberry, also called black elder and Sambucus nigra. As the name suggests, the tree is native to Europe but grows across the world. 

Other varieties of this tree include American elder, dwarf elder, blue elderberry, danewort, red-fruited elder, and antelope brush. 

The tree can grow to be 30 feet tall. It flowers with small clusters of white or cream-colored flowers that are called elderflowers. The berries are found in bunches and are small and a dark blue hue. The raw berries are relatively sour and should be cooked before consumption. The flowers are delicate and can be eaten raw or cooked. Many people choose to make elderflower cordial using them. 

What have elderberries been used for historically?

All different parts of the plant have been used throughout history for many different purposes. The flowers and leaves have long been consumed as a form of pain relief. They are believed to reduce swelling and inflammation, helping with injuries. As well as this, the leaves are a diuretic, meaning that they help to stimulate the production of urine and sweating. 

The bark has been used as an emetic, diuretic, and laxative. This means that consuming the bark triggers vomiting, urination, and can help to relieve the symptoms of constipation.

The berries are either juiced or dried. The resultant product is then consumed as a treatment for infections, flu, headaches, and dental pain. The juice is also believed to help with sciatica, cardiovascular pain, and nerve pain. As with the other parts of the plant, the juice and berries can be consumed as a diuretic and laxative. 

Elderberries are also commonly cooked and turned into jelly, chutneys, wine, and pies. As we have already mentioned, the flowers can be cooked into a sugar syrup to make a cordial to mix with water or into tea.

Elderberries are full of antioxidants. These are compounds that help to protect your body’s cells against the damaging effects of free radicals.

Elderberries are particularly high in phenolic acid which has strong anti-oxidative effects.

Other antioxidants in elderberries are the flavonols quercetin, kaempferol, and isorhamnetin. These are found in 10 times the quantities in the elderflowers. 

The berries also contain anthocyanins, bioflavonoid compounds that give the dark blue hue. These have been reported to lower blood pressure, protect your cells against cancer, and reduce your diabetes risk.

While there are many clear benefits to consuming elderberries, there are also some dangers. The raw berries, bark, and seeds of the tree all contain compounds that are known as lectins. If these are consumed in too high quantities you are likely to experience stomach and digestive problems. 

The tree also contains cyanogenic glycosides. These are compounds that have the potential to release cyanide, like almonds and apricot seeds. In order to ingest a fatal dose, you would need to eat more than 3 kilos of leaves or berries. The cyanide in the berries and leaves will be removed during the cooking process.
