Mapping the Technological and Pharmacological Landscape of Casearia sylvestris: An Evidence-Based Prospection for Wound Healing and Pain Management.

Casearia sylvestris Sw. (Salicaceae) is a South American medicinal plant traditionally used for the treatment of inflammatory conditions, pain, and wound healing, with its biological activity mainly attributed to clerodane diterpenes and flavonoids. This study assessed its therapeutic potential in wound repair and pain modulation by integrating patent landscaping with scientific evidence. A systematic search was conducted in the Orbit-Questel database to identify relevant patent families, complemented by a literature review in PubMed, Scopus, and Web of Science. Patents and studies reporting analgesic, anti-inflammatory, or wound-healing activities were included. Of the 41 patent documents retrieved, eight met the inclusion criteria and were classified into three main technological strategies: (i) nanostructured sprays and biofilms containing glycolic extracts of C. sylvestris; (ii) synergistic herbal combinations; and (iii) innovative formulations for oral mucositis. Some patents also described the isolation of clerodane diterpenes with cytomodulatory and antitumor properties. Among 51 screened scientific articles, seven were included, providing generally supportive but heterogeneous evidence. Despite its promising potential, limitations related to chemical standardization, methodological variability, and the lack of clinical and mechanistic studies remain, highlighting the need for further research to enable safe and effective therapeutic applications.
