ELDERBERRY

Well known as an anti-cold herb, studies suggest elderberry ( Sambucus nigra) relieves colds, flu, sinus problems, allergies, inflammation, nerve pain and chronic fatigue. When used within the first 48 hours of the onset of flu symptoms, studies found that elderberry reduced the duration of flu by an average of four days. As an immune booster, the berries contain chemical compounds called anthocyanidins, which are are known to have immunostimulant effects.

Both the flower and the berry have traditionally been used to treat diabetes. Studies show that extracts of elderflower stimulate glucose metabolism and the secretion of insulin, lowering blood sugar levels. You can make a syrup from the berries or an infusion from the flowers to treat the various ailments.

Note that elderberry is a pest pant in some parts of the country. They can thrive in terrible soil, and indeed often flower and fruit better under such conditions.

In the garden they are best given a sunny, dryish spot. Once established, feed infrequently and water only when very dry.
