Black elderberries have been studied most widely as a treatment for the viral flu. Scientists believe that the berry stimulates the immune system’s chemical responses, bringing relief from flu symptoms and possibly shortening its duration.
Elderberries might also help reduce symptoms of the common cold. A study conducted with air travelers suggested that taking black elderberry extract lessened the length and severity of a cold.
Black elderberries contain sterols. These substances are found in plants, and they help stop your body from absorbing cholesterol. Studies show that adding just 2 grams of sterol to your daily food intake can reduce your LDL cholesterol (or “bad” cholesterol) by 5% to 15%.
Lower Risk of Heart Disease
Black elderberries contain a type of antioxidant called flavonoids. If you take black elderberries regularly, these flavonoids might lessen your risk for developing heart disease.
Polyphenols are another type of antioxidants present in black elderberries. These compounds have been found to help control the blood’s glucose level. The polyphenols in black elderberries may also help lower the risk of developing type 2 diabetes.
