NEW PATENT FOR ElderCraft®

Black Elderberry extract inhibits the replication of SARS-CoV2 in vitro

A new study of the researchers at the University Erlangen has shown ElderCraft® Black Elderberry Extract has a strong antiviral effect against SARS-CoV-2. Encouraged by the findings, IPRONA has filed to internationally patent ElderCraft® for use in the prevention and treatment of COVID-19.

The University of Erlangen, Institute for Virology under the direction of Prof. Schubert studied the effect of ElderCraft®, an extract made by IPRONA from Sambucus nigra, L. black elderberries (variety Haschberg) on the SARS-CoV-2 coronavirus that causes COVID-19. The tests found the extract inhibits the replication of the wildtype virus, as well as the variants of concern Alpha and Beta, at very low concentrations.

Ongoing, further studies will evaluate the efficacy versus other variants of concern and seek to identify the Mode of Action by using time of application studies. Interestingly, the proprietary production process IPT (IPRONA Polyphenol Technology) used to make ElderCraft® seems to capture the inhibitory properties more efficiently than standard concentration techniques.

IPT is an entirely mechanical, solvent-free separation and ultra-filtration process that IPRONA uses to extract an active blend of natural fruit anthocyanins, polysaccharides and berry micronutrients from elderberries grown in southeast Austria by a cooperative of 250 farmers.

While the current research is still ongoing, the use of ElderCraft® for the prevention and treatment of  COVID-19 has been filed as an international patent application. The study results will be published in international journals over the course of the year, adding to the large volume of evidence of the positive effects of elderberry.

“It is fascinating to see that IPRONA`s elderberry extract ElderCraft® is able to inhibit the replication of SarsCov viruses even at very low concentrations. It has been known for a while that black elderberry is active against common influenza viruses, but this is the first time that an activity against the coronavirus SARS-CoV-2 and its variants of concern has been found. This opens the door for us and our partners to develop innovative Nutraceuticals as well as therapeutic products for the prevention and treatment of COVID-19” Stephan Plattner, Scientific Director of IPRONA, said.

The scientific studies build on centuries of use of black elderberry (Sambucus nigra L.) to treat flu and flu-like symptoms. In recent years, several human studies have confirmed the efficacy of black elderberry by showing a significant reduction in the duration and intensity of symptoms during influenza infections (1,2). 
The most recent human clinical study showed that ElderCraft® is able to significantly reduce the duration and intensity of influenza infections in long-haul flight passengers (3). In vitro studies indicate direct inhibition of viral replication through the blockage of viral receptors and the inhibition of key enzymes involved in viral replication (4). Other in vitro studies show the immune system seems to be positively influenced by components such as the polysaccharides present in the fruit of black elderberry (5).

Interest in those effects has increased during the COVID-19 pandemic. Even though infection with SARS-CoV-2 induces mild flu-like symptoms in the majority of those affected, some patients develop a severe form of the disease, including a progressive pneumonia due to an overreacting immune system. Therapeutic options for patients with moderate-to-severe COVID-19 remain limited and escape variants represent an additional threat. Accordingly, the development of novel anti-viral treatment options is eagerly awaited.
