We delved into how elderberry, specifically from the black elderberry fruit, impacts the flu virus, H1N1. Using an innovative technique called Direct Analysis in Real Time Mass Spectrometry (DART TOF-MS), we were able to identify the powerful anti-viral properties of elderberry extract without the need for complicated processes like separation or derivatization.
Our findings revealed that elderberry extract does indeed inhibit H1N1 infection in a lab setting, with an effective concentration (IC50) of 252 micrograms per milliliter. Interestingly, we discovered that flavonoids present in the elderberry bind to H1N1 virions—essentially blocking their ability to infect host cells.
Among the compounds, two key flavonoids emerged: the 5,7,3',4'-tetra-O-methylquercetin and dihydromyricetin. These compounds not only bound to the virus but also effectively prevented infection. Notably, the tetra-O-methylquercetin demonstrated an impressive IC50 of just 0.13 micrograms per milliliter, which is comparable to well-known antiviral medications like Oseltamivir and Amantadine.
In summary, elderberry shows promising potential as a natural remedy against the H1N1 flu, offering a fascinating area for further research and utilization in flu prevention strategies.

Elderberry effective against flu pathogens
We aimed to investigate the effectiveness of a standardized elderberry extract against influenza viruses and respiratory bacterial pathogens. The study utilized liquid cultures to examine how various concentrations of the elderberry extract—specifically 5%, 10%, 15%, and 20%—inhibited bacterial growth.
Our findings revealed that the elderberry extract is not just a potential ally against flu viruses, but also demonstrates activity against several harmful bacteria. We specifically tested its effects on both H5N1-type influenza A and influenza B viruses using reputable laboratory methods.
The results suggest that elderberry could offer additional strategies for combating infections, particularly during the flu season when complications often arise from bacterial super-infections following viral illnesses. These findings encourage the exploration of natural products like elderberry as a supportive treatment for respiratory infections.

We evaluated the effectiveness of elderberry juice, specifically concentrated juice (CJ-E), in combating the human influenza A virus (IFV). Our experiments involved administering CJ-E to mice infected with IFV to observe any potential antiviral effects. While we found that CJ-E had a strong impact on the mice, its antiviral action was less impressive when tested in a controlled cell culture environment.
To further assess its effects, we separated CJ-E into different fractions using ultrafiltration and anion-exchange chromatography. We concentrated on the high-molecular-weight fractions of CJ-E, which appeared to significantly suppress viral replication in the mice's bronchoalveolar lavage fluids (BALFs). Moreover, these fractions seemed to boost the production of IFV-specific neutralizing antibodies in the serum, along with increasing secretory IgA levels in BALFs and feces.
Particularly, one fraction, Fr. II from the high-molecular-weight group, which contained acidic polysaccharides, showed notable strength in defending against the flu infection. In conclusion, our findings suggest that CJ-E can stimulate the immune response and may play a preventative role against the influenza virus infection.

We explored how European black elderberry affects the immune response, particularly regarding flu infections. Through comparing its water extract and polysaccharide fractions to a traditional alcoholic extract, we focused on the role of dendritic cells (DCs), which are crucial for triggering strong T cell responses.
Our findings showed that the water extract and its polysaccharide components effectively matured DCs, enhancing their ability to stimulate T cells significantly. In contrast, the traditional alcoholic extract did not demonstrate any capacity to induce T cell stimulation.
We also observed that the water extracts promoted the production of key inflammatory cytokines like IL-6, TNF-α, and IFN-γ, contributing to a robust immune response, which may be beneficial in fighting off viruses like influenza. Thus, it appears that the polysaccharides from elderberry extracts can play a significant role in modulating the immune system, potentially equipping us to better combat viral threats.

We examined how elderberry might impact flu treatment based on several studies. From 1995 to 2013, three clinical trials looked specifically at different elderberry preparations, and all concluded that elderberry could be effective against influenza. However, it's important to note that these studies involved only 77 people, which is quite small for drawing definitive conclusions.
While the potential for elderberry's effectiveness seems promising, the limited sample size means we should be cautious in making broad claims about its benefits. There were no human or animal studies mentioned that specifically researched the safety of elderberry during pregnancy, presenting a gap in knowledge that is concerning for pregnant women considering herbal treatments for flu.
Overall, while elderberry appears effective against the flu based on the small trials, we need much more comprehensive research to better understand its efficacy and safety, particularly for vulnerable populations like pregnant women.

We explored the effectiveness of elderberry in treating and potentially preventing flu-related illness. This involved a systematic review of five randomized trials, which helped us examine whether elderberry could play a beneficial role in combatting viruses like the flu.
The findings suggest that while elderberry might not lower the risk of catching the common cold, it could potentially reduce the duration and severity of cold symptoms. We learned that elderberry may also shorten the duration of influenza, but the certainty of these benefits is still uncertain.
Interestingly, when comparing elderberry to oseltamivir, a common antiviral medication, elderberry appeared linked to a lower risk of influenza complications and side effects. However, we found no substantial evidence connecting elderberry to significant inflammatory outcomes. Some studies hinted that elderberry might influence certain inflammatory markers, but this effect may lessen with prolonged use.
Overall, we did not find strong, clear-cut benefits from elderberry in treating flu, stressing the need for more research to confirm these findings. Though it seems to be a safe option without overstimulating the immune system, the evidence remains inconclusive, and more studies are essential to draw firmer conclusions.

Elderberry's variable effectiveness against influenza
We investigated the effects of elderberry fruit on flu viruses, specifically how it interacts with the H9N2 influenza strain in human epithelial cell cultures. Our approach involved treating the virus and cells with various concentrations of elderberry extract before and after infection to see its influence on virus replication.
During our experiments, we noticed that at lower doses of elderberry extract, the viral activity actually increased. This indicated that the herb didn’t stop the virus from replicating. However, when we applied higher concentrations—specifically 40 and 80 μg/mL—we observed a significant reduction in both the amount of virus present and the production of viral proteins. This suggests elderberry may interfere with how viruses enter cells or how they release from them.
Importantly, the results hint that elderberry's effectiveness might stem from its interaction with lipid rafts in cell membranes. These rafts are crucial for the viruses' fusion and budding processes. Our findings underscore the importance of dosage and timing when using elderberry for treating influenza, highlighting the complexity of herbal treatments.
