Senecio scandens Buch. - Ham.: A comprehensive review of botany, phytochemistry, biological activity, toxicity,...

Senecio scandens Buch.-Ham., a medicinal herb from the Asteraceae family, contains flavonoids, terpenoids, and alkaloids as its primary bioactive compounds. It is commonly used in the treatment of ocular diseases and dermatological conditions. However, with its expanding applications across various fields, growing attention has been directed toward the potential safety concerns associated with its use.

This article systematically reviews existing literature on S. scandens, examining its botany, phytochemistry, biological activity, toxicity, applications, and development utilization, to provide a theoretical basis for in-depth exploration of its pharmacological mechanisms and resource development.

This study conducted a systematic review of literature on S. scandens published from 1972 to 2025, based on databases including PubMed and Web of Science. Plants names are provided in accordance with "The Plant List" (https://wfoplantlist.org/).

Over 200 chemical constituents, primarily flavonoids, terpenoids, and alkaloids, have been isolated and identified from S. scandens, endowing it with diverse biological activities such as anti-inflammatory, antibacterial, antioxidant, and anti-tumor effects. To address potential hepatorenal toxicity from its pyrrolizidine alkaloids, relevant safety guidelines have been gradually established alongside various clinical dosage forms. It is also widely used in fields including medicine, animal husbandry, agriculture, and cosmetics.

By systematically reviewing the botany, phytochemistry, biological activity, toxicity, application, and development and utilization of S. scandens, this paper identifies key utilization obstacles, proposes future research directions, and provides a theoretical framework for its further development.
