Botanical Overview
Sea Wormwood (Artemisia maritima) belongs to the Asteraceae family. While not among the most extensively documented medicinal plants, this species has recorded uses that warrant attention from researchers and practitioners. The daisy family (Asteraceae) is one of the largest plant families, characterized by composite flower heads (capitula) that contain many small florets surrounded by bracts. Plants range from tiny alpine herbs to large tropical trees. The family includes many medicinally important species with bitter compounds and essential oils.
