Botanical Overview
Giant Reed (Arundo donax) belongs to the Poaceae family. While not among the most extensively documented medicinal plants, this species has recorded uses that warrant attention from researchers and practitioners. The grass family (Poaceae) includes annual and perennial herbs with hollow, jointed stems and narrow leaves with parallel venation. The flowers are reduced and arranged in spikelets, and the fruits are grains (caryopses). This family provides the majority of the world’s food calories through cereals.
