1. European elderberry is packed with polyphenols, particularly anthocyanins, which make up about 80% of its total polyphenol content.

2. Research indicates that elderberry extracts might benefit various aspects of health, from heart and brain function to inflammation management and metabolic health. Scientists are also exploring its possible antiviral properties and effects on immune function.

3. The berries boast a diverse array of bioactive compounds. This chemical complexity is believed to underpin elderberry's broad spectrum of potential health effects.

4. Elderberry's use in traditional medicine, especially for respiratory issues, has a long history. Today, it's gaining attention in scientific circles, particularly for its potential role in supporting immune health against various infections.

5. The beneficial compounds in elderberries can vary significantly. A study of 11 cultivars over three years found total polyphenol content ranging from 852.6 to 2541.6 mg per 100 grams of fresh weight.
