Rosemary
Salvia rosmarinus
Salvia rosmarinus, commonly known as rosemary, is an aromatic evergreen shrub traditionally used in Mediterranean and European herbal medicine. While its use in traditional practices for medicinal purposes has not been extensively documented, it has shown potential in various scientific studies. Research indicates that the essential oil from Salvia rosmarinus 'Eretto Liguria' exhibits strong larvicidal activity against the tomato leaf miner, with an LC50 value below 1% at 72 hours. Additionally, chitosan treatment enhances physiological and metabolic responses in Salvia rosmarinus under combined drought and heat stress conditions, improving its resilience and phytochemical profile. Combined essential oils from multiple plants have shown enhanced efficacy against aphids compared to individual oils, though the specific role of rosemary is not highlighted in these studies. The hydrosols derived from Salvia rosmarinus contain a relatively higher presence of polar oxygenated compounds compared to its volatile oil. Safety concerns for Salvia rosmarinus are minimal; no major issues have been recorded. There are also no reported drug interactions, though further research is needed to fully understand the potential effects and applications in various contexts.
