Blood sugar relates to the amount of glucose present in the bloodstream. Symptoms of low blood glucose, or hypoglycemia, include paleness, sweating, headache, trembling, confusion and seizure. At the other end of the spectrum is high blood glucose, or hyperglycemia, which may produce increased thirst and frequent urination, according to the American Diabetes Association. Elderberry supplements may affect blood glucose levels, but scientific evidence of the effect is lacking. Herbal remedies cannot replace professional medical advice, so talk to your doctor about your blood sugar, and ask whether elderberry supplements are safe for you.
Elderberry
The berries of the Sambucus nigra bush, better known as elderberries, contain anthocyanins, which are natural pigments that give the berries their deep blue-black coloring. Anthocyanins are glycosides, or components that bind to sugar molecules. The glycoside units in elderberry might affect metabolism and blood glucose levels, but clinical studies are necessary to confirm these actions.
Blood Sugar Effects
Taking elderberry might lower blood sugar levels, according to the University of Maryland Medical Center. For diabetics already taking medication to control glucose levels, using elderberry supplements might result in hypoglycemia. Elderberry supplements, however, are usually taken as a natural treatment for viral infections and sinusitis, and are not considered a remedy for high blood sugar.
Administration
The "Gale Encyclopedia of Alternative Medicine," recommends following dosage instructions on the package of elderberry supplements, but limiting daily intake to no more than 15 g of the herb. In addition to supplements, elderberry is available in standardized liquid extract and herbal tea.
Considerations
Elderberry supplements are generally safe for most adults when taken as recommended. Due to a lack of safety research, do not take the supplements if you're diabetic, pregnant, breastfeeding or if you have kidney or liver disease. Do not give elderberry to children, unless directed to do so by a doctor. Side effects are rare, according to the "Gale Encyclopedia," but include mild abdominal upset and allergic reaction. Elderberry may interfere with medications you're taking.
Blood sugar disorders are serious conditions. See your doctor for regular blood glucose screening and use elderberry as part of a doctor-recommended treatment plan.
