Elder is a plant native to most of Europe, North America, and southwest Asia. Its flowers and berries have a long history of use in traditional European medicine. Our  elderberries naturally grow on our property in La Garrotxa.
 
Elderberries are an immune system booster, and are higher in flavonoids than blueberries, cranberries, goji berries and blackberries. They're also anti-inflammotory, which may help with sinus infection symptoms, as well as promote urination and bowel moments.
