This study examines the role of herbal medicines in public health, addressing aspects of safety, efficacy, and health regulation, and highlighting the challenges and prospects for their safe integration into the health system. The use of herbal medicines has expanded in recent decades, driven by the appreciation of integrative and complementary practices and the recognition of the therapeutic potential of medicinal plants. In Brazil, the inclusion of these products in the Unified Health System (SUS) is achieved through specific public policies aimed at guaranteeing qualified, safe, and evidence-based access. This is a narrative literature review, covering the last ten years, based on national and international scientific articles, as well as official documents from the Ministry of Health and the National Health Surveillance Agency. The findings demonstrate that, while herbal medicines offer relevant clinical and socioeconomic benefits, their inappropriate use can lead to health risks, such as adverse reactions, drug interactions, and variations in product quality. Furthermore, the efficacy of many herbal medicines still lacks robust scientific evidence. It is concluded that promoting the rational use of herbal medicines requires strengthening health regulations, training health professionals, and expanding clinical research.
