Black elderberry

Rich in antioxidants, elderberries can be used for a dizzying variety of applications. However, research on elderberries shines its light on its potential to remedy cold and flu symptoms.  
In a study conducted on air-travellers, participants who took an elderberry supplement standardised to 90mg OPC showed significantly reduced cold symptoms and cold duration compared to placebo. In another study on sufferers of cold symptoms, elderberry lozenges provided relief from coughing, nasal mucus and congestion. It is thought that the OPCs found in elderberries may improve immune function, contributing to cold-relief for sufferers.
