As elderberry syrup becomes more mainstream, it’s important to call out a few scientific articles about elderberries.

Below are peer-to-peer research journals citing evidence of the efficacy and effectiveness of elderberry syrup. I will continue to update this list as more and more research is unveiled.

Anti-influenza activity of elderberry (Sambucus nigra)

The study:


  • Elderberry exhibits multiple modes of therapeutic action against influenza infection.
  • Elderberry showed a mild inhibitory effect at early stages of the influenza cycle.
  • Its impact on the post-infection phase is considerably stronger than the early stages.
  • Elderberry possesses immunomodulatory property through stimulation of cytokines.
  • Cyn 3-glu had direct effects on influenza but did not stimulate the immune system.


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.

Elderberry syrup inhibits the flu & reduces symptoms.

The Study:

A significant improvement of the symptoms, including fever, was seen in 93.3% of the cases in the SAM-treated group within 2 days, whereas in the control group 91.7% of the patients showed an improvement within 6 days (p < 0.001).

A complete cure was achieved within 2 to 3 days in nearly 90% of the SAM-treated group and within at least 6 days in the placebo group (p < 0.001). 


The safety and effectiveness of elderberry syrup used against the flu.

The Study:

The global evaluation scores for the elderberry group showed a pronounced improvement. This difference was significant.

None of the patients reported any adverse reactions related to the medication. One participant receiving elderberry syrup disliked the taste.

As sedation is a main side-effect of most anti-influenza medications, the participants were specifically asked if they had any problem with sedation during the study period; none of the patients reported having such problems.


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.

The effects of elderberry syrup on air travelers.

The Study:

Travelers using elderberry from 10 days before travel until 4–5 days after arriving overseas on average experienced a 2-day shorter duration of the cold and also noticed a reduction in cold symptoms.
