Sambucus australis (Viburnaceae) is a wild and native species from South America used in traditional medicine. The objective of this review is to collect information on geographic distribution, systematics and phylogeny, morphological and anatomical characteristics, biochemical composition, and biological and ethnobotanical activity for its valorization as a wild food plant with edible and medicinal properties. S. australis grows naturally in Brazil, Paraguay, Bolivia, Uruguay, and Argentina. It is a shrub or small dioecious tree. Leaves are imparipinnate, generally with 11 opposite leaflets. Flowers with a 1 cm diameter are presented in inflorescences as terminal corymbs, with an inferior, pentacarpellate and pentalocular ovary. Leaves and flowers have a high content of total phenols. The following secondary metabolites were found: quercetin, isoquercetrin, quercetin, Kaempferol, hyperoside, rutin, and di-O-caffeoylquinic, chlorogenic, gallic, caffeic, and ellagic acids. Its biological activity was described as anti-inflammatory, antioxidant, allelopathic, antiproliferative, antigenotoxic, antiparasitic, hypoglycemic, lipid-lowering, antibacterial and synergizing. Ethnobotanical studies have shown that its flowers, leaves, fruits, bark and roots are used to treat asthma, colds, flu, diabetes, measles, etc. Knowledge about the characteristics, properties, and uses of S. australis is an important contribution for its valorization, conservation, sustainable use and domestication.
