inferred from antiviral action

Upper respiratory symptoms are often treated with over the counter drugs, antibiotics, and antiviral medications. Due to concerns about safety and efficacy, there is a demand for an alternative solution. Black elderberry (Sambucus nigra) has been used to treat cold and flu symptoms, but there are no large-scale studies or meta-analyses. This meta-analysis quantifies the effects of elderberry supplementation and evaluates moderators including vaccination status and the underlying pathology. This analysis included a total of 180 participants and evaluates moderators such as vaccination status and cause of the upper respiratory symptoms. Supplementation with elderberry was found to substantially reduce upper respiratory symptoms. The quantitative synthesis of the effects yielded a large mean effect size. These findings present an alternative to antibiotic misuse for upper respiratory symptoms due to viral infections, and a potentially safer alternative to prescription drugs for routine cases of the common cold and influenza.
Elderberry has been used in folk medicine for centuries to treat influenza, colds and sinusitis, and has been reported to have antiviral activity against influenza and herpes simplex. We investigated the efficacy and safety of oral elderberry syrup for treating influenza A and B infections. Sixty patients (aged 18-54 years) suffering from influenza-like symptoms for 48 h or less were enrolled in this randomized, double-blind, placebo-controlled study during the influenza season of 1999-2000 in Norway. Patients received 15 ml of elderberry or placebo syrup four times a day for 5 days, and recorded their symptoms using a visual analogue scale. Symptoms were relieved on average 4 days earlier and use of rescue medication was significantly less in those receiving elderberry extract compared with placebo. Elderberry extract seems to offer an efficient, safe and cost-effective treatment for influenza. These findings need to be confirmed in a larger study.

Mechanistic basis
This use is associated with the plant's antiviral action. Further evidence for that pharmacology:
Elderberry ( Sambucus nigra L.) is rich in many bioactive compounds and exhibits diverse health functions, of which an understanding can be helpful for its better utilization in the food industry. This review mainly summarizes recent studies about the bioactive compounds and health functions of elderberry, highlighting the potential mechanism of action. In addition, the applications of elderberry in foods are also discussed. Elderberry contains diversely bioactive ingredients, such as (poly)phenolic compounds and terpenoid compounds. Recent studies report that some food processing methods can affect the content of bioactive compounds in elderberry. Additionally, elderberry exhibits various health functions in vitro and in vivo , including antioxidant, anti-inflammatory, anticancer, anti-influenza, antimicrobial, antidiabetic, cardiovascular protective, and neuroprotective activities, and their potential molecular mechanisms are associated with regulating some key signaling pathways and molecular targets. Up to now, there have been limited clinical trials supporting the health benefits of elderberry. Overall, elderberry is a promising dietary source of bioactive ingredients and has the potential to be developed into functional foods or nutraceuticals for preventing and treating certain chronic diseases.
Background The novel severe acute respiratory syndrome coronavirus 2 emerged in 2019. Health-care systems around the world are looking for alternative prevention and treatment remedies. Herbal supplements are popular among consumers as a complementary method to prevent and treat illnesses. One of them is Sambucus nigra . Methods We searched for related articles in Scopus, Web of Science, PubMed, Google Scholar, and the Directory of Open Access Journals using the following keywords: elderberry, S. nigra , and COVID-19. Results Elderberry has antiviral properties due to its ability to modulate inflammatory cytokines. The current evidence suggests elderberry is appropriate for the prevention and initial treatment of viral disease. Concerns have been raised that elderberry may overstimulate the immune system, increasing the risk of a cytokine storm. There is not yet enough evidence to support this claim. Conclusions For COVID-19 patients, further research is required since elderberry may provoke a cytokine storm if administered therapeutically.
Purpose of review Black elderberry has come to the fore in recent years due to its health benefits. Black elderberry fruit (Sambucus nigra L.), collected from natural sources, has a rich content of protein, vitamins, antioxidants, unsaturated fatty acids, and minerals as it contains conjugated and free forms of amino acids. Recent findings Black elderberry can prevent oxidative stress and reduce blood pressure and prevent cardiovascular diseases, diabetes mellitus, neurodegenerative diseases thanks to the polyphenols it contains. It can prevent diseases, stimulate the immune system, show an antitumor effect, and be effective in the course of disease processes by rising the activity of antioxidant enzymes, including glutathione. Since black elderberry is a promising food in terms of bioactive components, it is considered as promising to treat and prevent many diseases. However, it is not correct to prove its beneficial effects on the prevention of chronic diseases and to make generalisations. Therefore, there is a need of more comprehensive evidence-based clinical studies and data. This review examined current evidence and discussions about the health-related effects of black elderberry, which contains many biologically active components such as polyphenols, phenolic acids, flavonols, proanthocyanidins and anthocyanins, as well as terpenes and lectins, and offered some suggestions on its use in the future.
