Sambucus, commonly known as "elderberry," is a plant in the Adoxaceae family, which includes several species of shrubs and small trees. The most popular species used for medical and nutritional purposes is Sambucus nigra, or European elderberry.
Sambucus or elderberry is a berry plant with small, round, dark purple fruits. Its usage history dates back to the Neolithic period, with evidence found in areas of present-day Switzerland and Italy. Ancient Egyptians also used Sambucus or elderberry to treat burns.
In ancient Greek and Roman times, "Hippocrates," regarded as the father of medicine, dubbed the elderberry tree "nature's medicine chest." As a result, Sambucus or elderberry is increasingly used in medicine and health care today.
Immune System Enhancement: Research by Barak et al. in 2001 found that elderberry extract can stimulate the immune system, particularly increasing the production of cytokines, proteins crucial in immune response.
Antiviral Properties: A study by Zakay-Rones et al. in 2004 showed that elderberry extract can inhibit the multiplication of influenza and herpes viruses. Research also indicates that consuming elderberry products may help reduce the duration and severity of cold and flu symptoms.
Antioxidant Properties: A study by Młynarczyk et al. in 2018 found that elderberry is a rich source of anthocyanins, which have high antioxidant properties. These help protect cells from damage caused by oxidative stress and may help reduce the risk of certain chronic diseases, such as cardiovascular diseases.

Wastewater Treatment Capability: A study by Salazar et al. in 2014 showed that the elder (Sambucus) plant has potential for use in phytoremediation, able to absorb heavy metals from soil and water. This could lead to the development of natural methods for environmental restoration.
Ability to Enhance the Effectiveness of Modern Medicines: A preliminary study by Jędrejek in 2017 showed that key compounds in Sambucus may help increase the absorption of certain drugs, which could lead to the development of methods to enhance drug efficacy.
