Folk medicine has used elderberries for hundreds of years. Indigenous people have used them to treat rheumatism and fevers, and ancient Egyptians use them for burns and to improve their skin. Today, scientific research has examined elderberries for their effects on the immune system, which may help fight colds, the flu, and similar conditions. Elderberries can come in the form of capsules, lozenges, and syrups, but you can also make your own DIY elderberry syrup in an instant pot when the flu season comes in.

The Potential Health Benefits of Elderberry

Elderberry, also known as elder, is a family of flowering shrub species native to Europe and North America. The berries are dark in color, often black, blue, or purple. They have a tart flavor when they are used in wines, pies, jams, and sauces. In addition to syrups and lozenges, they can be sold as supplements, teas, and gummies.

Elderberries contain many nutrients and vitamins, including fiber, potassium, vitamin C, vitamin A, calcium, folate, iron, and antioxidants. Research has found that they may help treat colds and the flu; however, the studies are small and not entirely conclusive. A review from 2010 found that these berries can have antioxidant and antiviral properties although the authors added that more research is needed to verify these effects.

Another study found that 60 people who took 15 milliliters (ml) of elderberry syrup four times a day had their flu-like symptoms improve four days faster than those who took a placebo. Similarly, another study followed 32 people with similar symptoms who took lozenges with 175 milligrams (mg) of elderberry extract and reported an improvement in their symptoms. One study examined if elderberry extract could prevent people from having cold-like symptoms after air travel. People who took elderberry lozenges still experienced these symptoms but less severely and for less time than those who didn’t.

The Potential Risks

Although these studies are promising, they tend to use a small sample size and therefore require further research to verify these health benefits. So while elderberry syrups and the like could help with flu symptoms, they are not a substitute for a flu shot. Also, there has been no published research evaluating its potential effects against COVID-19; the U.S. Food and Drug Administration and Federal Trade Commission had taken action against companies who had marketed elderberry products as anti-coronavirus treatments.
