How Elderberries Can Boost Immunity and Help Fight Viruses
Since ancient times, herbs and natural remedies have been trusted allies against a wide range of illnesses—including viral infections. Thanks to their rich concentration of powerful plant compounds, many herbs offer significant support when fighting viruses.
This is why natural health practitioners often favor plants for healing. However, it’s important to note that not all herbal remedies are backed by extensive human studies, so a balanced and informed approach is always best.
Today, let’s spotlight one remarkable and nutritious berry that stands out for its immune-boosting properties: the elderberry.
Elderberry: The Delicious Berry with Powerful Benefits
Elderberries are best known for their tart, refreshing flavor, often featured in jams, syrups, wines, and desserts. But beyond their taste, elderberries are celebrated for their impressive ability to support immunity, particularly when it comes to protecting against viruses.
New Research: Elderberries Can Help Defend Against Viruses and the Flu
The black elder shrub, native to Europe and North America, produces flowers and fruit traditionally used in seasonal treats.
Harvesting happens in late summer or early autumn, once the berries are ripe—a crucial detail because unripe or uncooked elderberries can be toxic.
The fresh leaves, bark, roots, flowers, and young buds contain bitter alkaloids and glucosides that can produce hydrocyanic acid under certain conditions, making careful preparation essential.
Despite these precautions, elderberry-based foods and remedies have remained popular worldwide, praised for strengthening the immune system and helping to ward off illnesses.
Why Are Elderberries So Good for Your Immunity?
A study conducted by researchers at the University of Sydney revealed that elderberries possess powerful antiviral properties that can help fight against infections.
Co-author Golnoosh Torabian, Ph.D., explains that elderberry extract can block key viral proteins involved in the early stages of flu virus infection—preventing the virus from attaching to and entering healthy cells.
What the Research Found
In the study, researchers processed commercially grown elderberries into a serum and administered it at different stages of the influenza cycle:
-
Before infection: The elderberry serum had a mild effect, helping to prevent viruses from attaching to cells.
-
During infection: The serum had a stronger effect, actively stopping the virus from replicating within the infected cells.
This dual-action surprised researchers. As noted by co-author Peter Valtchev, Ph.D., blocking the virus at multiple stages offers a greater chance of stopping the infection.
Additionally, elderberry extract was found to stimulate the immune system, prompting cells to release cytokines—chemical messengers that coordinate a stronger defense against pathogens.
The Power of Anthocyanidins
The study concluded that elderberries’ antiviral abilities are largely thanks to anthocyanidins, the natural plant pigments found in the berries.
Other research has also shown that anthocyanidins offer antioxidant benefits, helping protect cells from damage and supporting overall health.
Final Thoughts
While elderberries should always be prepared properly to avoid toxicity, their potential as a natural tool for boosting immunity and fighting viruses is incredibly promising.
With ongoing research supporting their benefits, elderberries continue to earn their reputation as one of nature’s most powerful allies for health and wellness.
