- High in vitamin C. There are 52 mg of vitamin C per cup of fruit, which accounts for 57% of the daily value (3, 4).
- High in dietary fiber. Elderberries contain 10 grams of fiber per cup of fresh berries, about 36% of the daily value (5).
- A good source of phenolic acids. These compounds are potent antioxidants that can help reduce damage from oxidative stress in the body (4, 6).
- A good source of flavonols. Elderberry contains the antioxidant flavonols quercetin, kaempferol, and isorhamnetin. The flowers contain up to 10 times more flavonols than the berries (4).
- Rich in anthocyanins. These compounds give the fruit its characteristic dark black-purple color and are a strong antioxidant with anti-inflammatory effects (4, 7).

Antioxidants are natural components of foods, including some vitamins, phenolic resin acids, and flavonoids, that are able to help remove these reactive molecules. Research suggests that diets high in antioxidants may help prevent chronic disease ( 8, 14, 15 ). The flowers, fruits, and leaves of the elderberry plant are excellent sources of antioxidants. For exercise, one of the anthocyanins found in the berries has 3.5 times the antioxidant ability of vitamin E ( 4, 15, 16, 17 ). One study comparing 15 different varieties of berries and another study comparing types of wine found that bourtree is one of the most effective antioxidants ( 18, 19 ). additionally, one survey found that antioxidant condition improved in people 1 hour after drinking 400 milliliter of bourtree juice. Another report in rats found that bourtree educe helped reduce inflammation and oxidative tissue wrong ( 20, 21 ).

Elevated uric acerb is linked to increased rake press and damaging effects on heart health ( 4, 26 ). What ’ s more, elderberry can increase insulin secretion and improve blood carbohydrate levels. Given that type 2 diabetes is a major risk component for heart and vascular disease, blood sugar management is authoritative in preventing these conditions ( 4, 9 ). A study found that bourtree flowers inhibit the enzyme alpha-glucosidase ( α-glucosidase ), which may help lower blood boodle levels. besides, inquiry on rats with diabetes given elderberry showed improved blood carbohydrate master ( 4, 16, 29 ). Despite these promise results, a direct reduction in kernel attacks or other symptoms of heart disease has not yet been demonstrated, and far studies in humans are needed .

This is a toxin besides found in apricot seeds and almonds ( 1, 3 4 ). There are 3 mg of cyanide per 100 grams of fresh berries and 3–17 mg per 100 grams of fresh leaves. This is fair 3 % of the estimated fatal drug for a 130-pound ( 60-kg ) person ( 2, 35 ). however, commercial preparations and cook berries do not contain cyanide, so there are no reports of fatalities from eating these. Symptoms of eating uncooked berries, leaves, bark, or roots of the bourtree include nausea, vomit, and diarrhea ( 2 ). There is one report of eight people falling ill after drinking the juice from impertinently nibble berries, including the leaves and branches, from the S. mexicana elder diverseness. They experienced nausea, vomiting, weakness, dizziness, numbness, and daze ( 36 ). fortunately, toxic substances found in the berries can be safely removed by cooking. however, the branches, bark, or leaves should not be used in fudge or juicing ( 2 ).
