Elderberry is a rich source of antioxidants and is now used, for example, in cough syrup and lozenges. But the use of elderberries is by no means new. Elderberry extract has been used in medicine for centuries to fight infections, clear the complexion and strengthen the immune system, experts at the Cleveland Clinic said in a recent edition Press release.

Shorter flu thanks to elderberry extract?
The results of the study so far have further increased the interest in elderberries. One study have shown, for example, that elderberry extracts reduce the duration of the flu by four days compared to a placebo. However, recent research suggests that elderberry isn’t effective at reducing the severity or duration of flu symptoms, the team said.
So last got one study from last year under the direction of Professor Dr. Michael Macknin of the Cleveland Clinic studies the usefulness of elderberry in treating people with influenza B. Influenza A and B are the two main types that cause seasonal flu epidemics.
The study looked at 87 people aged five and over who tested positive for influenza or flu between January 2018 and April 2019. Only 33 percent of those taking part in the study had received a flu shot. Participants had two or more of the following symptoms: body pain, chills, cough, fatigue, headache, nasal congestion, or sore throat.
All participants were randomly given either an elderberry extract or a placebo for five days. In addition, there was the option of taking the antiviral drug oseltamivir (Tamiflu). Participants aged five to twelve received a placebo or 15 ml (5.7 g) elderberry extract orally twice a day for five days. By contrast, people over the age of twelve received 15 ml of elderberry extract four times a day for five days.
Conflicting results with other studies
The results showed no difference in the severity or duration of flu symptoms between the elderberry and placebo groups. For the participants in the elderberry group who did not take oseltamivir, it took two days longer for the symptoms to subside compared to the placebo group.
This is in clear contradiction to previous studies. In these it was found that elderberries shortened the flu symptoms by four days, according to the experts. Here it becomes clear that there is an urgent need for further research on this topic.
Elderberries ineffective in protecting against COVID-19
Although some people have been suggested that elderberries can prevent COVID-19, there are no published studies examining the use of elderberries in COVID-19. The best prevention against COVID-19 remains a vaccination.
This also applies to the flu, as there are currently no effective drugs to treat the flu. In addition, a vaccination is crucial to curb the spread of the flu. (as)
