Elderberry is a shrub grown natively in Asia and cultivated in the United States. The plant's ripe fruit is the segment of the plant used for medical treatment. The unripe fruit, leaves, seeds and bark of the plant are toxic because they contain a compound chemically similar to cyanide, according to the University of Maryland Medical Center. Avoid toxic ingredients by purchasing elderberry supplements manufactured by a reputable company. Antioxidants may be the source of elderberry's beneficial effects. (See Reference 2)
Stimulates the Immune System
Elderberry may benefit the immune system, according to a 2001 study led by Vivian Barak from the Department of Oncology at Hadassah University Hospital and published in "European Cytokine Network." The study found that elderberry increases the production of chemical messengers that signal the brain to initiate an immune system response. This capability could prove useful for treating immuno-suppressive disorders such as AIDS or cancer, in conjunction with other therapies.
Reduces Symptoms of Sinus Infections
Elderberry may be beneficial as a treatment for bacterial sinus infections. According to the University of Maryland Medical Center, consuming elderberry along with an antibiotic and a decongestant can increase the rate of recovery from sinus infections. A sinus infection is a common disorder that occurs most often during allergy season.
Inhibits the HIV Virus
Elderberry may block the HIV virus from infecting healthy cells, according to a 2009 study led by Ryan Fink from University of Miami and published in "Antiviral Chemistry & Chemotherapy." The study's researchers reported that anti-viral drugs cause the HIV virus to mutate, preventing a cure. They studied the elderberry herb to find a treatment that would not alter the composition of the virus. The flavonoids and proanthocyanidins in the herb were the effective compounds.
Prevents Herpes Outbreaks
Elderberry may prevent herpes outbreaks, according to a 2006 study led by Julia Serkedjieva from the Bulgarian Institute of Microbiology, published in "Phytotherapy Research." The study found that when elderberry was combined with herbs St. John's wort and soapwort, the mixture prevented the propagation of the herpes virus. The medicinal compounds responsible for the herb's action include flavonoids, tannins and polysaccharides.
