People have used elderberry for its health benefits for hundreds of years. Elderberry contains antioxidants, and many believe it can relieve colds, fight the flu, and boost the immune system.
There is little scientific research into the effects of elderberries on people’s health. The National Center for Complementary and Integrative Health (NCCIH) state that more research is needed to confirm the truth of these possible health benefits.
This article will evaluate the evidence for these claims. It will also look at the possible side effects of consuming raw elderberries and suggest methods of preparation.
Elderberries are the fruit of the Sambucus tree. The most common type is the Sambucus nigra.
The tree has clusters of small white or cream elderflowers and bunches of small blue or black elderberries.
Native Americans and European herbalists have long used elderberries for their supposed range of health benefits. These include boosting the immune system to help the body fight off colds, flu, and other respiratory infections.
The elderberry contains certain compounds and substances that might have a beneficial impact on health.
We take a look at the evidence behind some of the main reported health benefits of elderberries:
Fighting colds and flu
There is some evidence to support the claim that elderberry can help treat colds and flu, though the available studies are small.
In another study, 32 people with flu-like symptoms took lozenges containing 175 milligrams (mg) of elderberry extract four times a day for 2 days. After 24 hours, they reported an improvement in symptoms, such as fever, headache, muscle aches, and nasal congestion.
A double-blind, randomized control trial looked at whether elderberry extract could prevent people from experiencing cold-like symptoms after traveling on an airplane. People took lozenges containing 300 mg of elderberry extract and 150 mg of rice flour twice a day for 10 days before traveling.
Researchers found that the capsules did not prevent the symptoms, but people who took elderberry had less severe symptoms that lasted for a shorter time.
Elderberry fruit contains high levels of flavonoids, which means it might have anti-inflammatory and antioxidant properties. These help to protect healthy cells from harmful free radicals that play a role in skin problems.
Elderberries contain high levels of vitamin A. The ANA also say that elderberries may soothe the skin, help ease the appearance of age spots, and prevent or lessen wrinkles.
Elderberries contain many vitamins and nutrients that can benefit people’s health.
- 870 mg of vitamin A
- 406 mg of potassium
- 52.2 mg of vitamin C
- 9 mg of folate
- 55 mg of calcium
- 2.32 mg of iron
Elderberries are also an excellent source of fiber, containing 10.2 g of dietary fiber per cup. This makes up a large amount of the recommended daily intake, which according to Dietary Guidelines for Americans is 34 g for men and 28 g for women.
Meeting daily fiber recommendations can have the following health benefits:
- prevent constipation
- improve bowel function
- protect against colorectal cancer
- reduce blood pressure
- protect against cardiovascular disease
- lower blood cholesterol
People can eat elderflowers raw or cooked. However, raw elderberries, as well as the seeds, leaves, and bark of the tree, contain a toxic substance.
Eating or drinking raw elderberries or another toxic part of the plant can lead to nausea, vomiting, and diarrhea.
Several elderberry capsules, lozenges, and syrups are commercially available for treating a cold or the flu. Elderberry-based skin care products are also available in some stores.
Do not eat raw elderberries as they can be poisonous.
However, there are various ways to prepare elderberries.
To make elderberry syrup:
- remove the stalks
- cook the berries in water and sugar
- boil the liquid to reduce it until it takes on a syrup-like consistency
People can then drizzle the syrup over plain yogurt or add it to a smoothie.
People have used elderberries for their potential health-boosting properties for many years, most notably to fight colds and the flu.
While there are a few studies that appear to support these claims, they tend to feature small numbers of participants. This means that researchers need to investigate further before they are sure about the health benefits of elderberries for all consumers.
Elderberries contain high levels of fiber. Consuming elderberries as part of a healthful diet may lead to some health benefits, including protection from cardiovascular disease and colorectal cancer.
However, do not eat raw elderberries, as they can cause nausea, vomiting, and diarrhea. It is also worth noting that elderberry syrup often contains high levels of sugar.
