Elderberry flowers contain a variety of compounds, including flavonoids, essential oils, triterpenes, tannins, and vitamins/minerals. Flavonoids act as antioxidants, providing anti-inflammatory and immune-boosting properties. Essential oils contribute to the flower’s aroma and may have antimicrobial effects. Triterpenes have potential anti-inflammatory and antiviral effects, supporting immune function. Tannins give elderflowers a slightly bitter taste and have astringent properties. Elderflowers also contain vitamins C and A, potassium, and calcium, contributing to overall health.
