The research on elderberry is constantly evolving. We’ve categorized and curated 50 scientific papers on the berries and flowers of the sambucus nigra plant as well as their chemical constituents that contribute to the nutritional density of the common elderberry tree.

We’ve hired Dr. Cathy Stein to help us understand these articles by creating easy-to-understand summaries. Dr. Cathy Stein has a PhD in epidemiology and her research focuses on infectious disease susceptibility.  She currently holds a tenured faculty position.

Processed elderberry (Sambucus nigra L.) products: A beneficial or harmful food alternative?

The study

    • Thermal processing, time and type of extraction solution greatly affected phenolics and cyanogenic glycosides in different elder-berry product

    • Processing significantly decreases the content of harmful cyanogenic glycosides but also affects beneficial anthocyanins.

    • Preparation of elderberry products, which include processing at high temperatures, does not always contribute to their inferior quality, as high temperature can effectively reduce the levels of harmful components and make elderberry products safer to consume.


The higher the better? Differences in phenolics and cyanogenic glycosides in Sambucus nigra leaves, flowers and berries from different altitudes













The study



















    • Elder leaves: there was a significant difference within chemical constituents (ie: cafeic acid higher in higher altitudes but ferulic acid higher in lower altitudes) based on different altitudes, but the altitude-location interaction wasn’t significant.

    • Elder flowers: there was a significant difference for flavonols and HCAs at higher elevations but a decrease in flavanone content.

    • Elder berries: in all cases, phenols increased when grown in higher elevations






































Sambucus nigra extracts inhibit infectious bronchitis virus at an early point during replication



















The study:



















These results demonstrate that S. nigra extract can inhibit IBV ( a coronavirus) at an early point in infection, probably by rendering the virus non-infectious.






































Advanced research on the antioxidant and health benefit of elderberry (Sambucus nigra) in food–a review



















The study:



















 • Elderberry bioactive compounds provide therapy for a number of diseases.•  Elderberry medicinal properties are associated with counteracting oxidative stress.•  Elderberry helps to prevent incidence of cardiovascular diseases and diabetes.



















How elderberry syrup activates the immune system.



















The Study:



















We conclude that (elderberry juice) had a beneficial effect by the stimulating immune response and preventing viral infection.






































Elderberry flavonoids prevent the flu.



















The Study:



















The elderberry extract inhibited Human Influenza A (H1N1) infection in vitro



















Further more…



















The H1N1 inhibition activities of the elderberry flavonoids compare favorably to the known anti-influenza activities of Oseltamivir (Tamiflu; 0.32 microM) and Amantadine (27 microM).






































Elderberry syrup benefits the immune system & inflammatory process.



















The Study:



















Sambucol was shown to be effective in vitro against 10 strains of influenza virus. In a double-blind, placebo-controlled, randomized study, Sambucol reduced the duration of flu symptoms to 3-4 days.

Sambucol Elderberry Extract and its formulations activate the healthy immune system by increasing inflammatory cytokine production. Sambucol might therefore be beneficial to the immune system activation and in the inflammatory process in healthy individuals or in patients with various diseases.
