Olive
Olea europaea
Olea europaea is a widespread plant species central to Mediterranean and Middle Eastern traditional medicine. It has been historically utilized as an aperient, astringent, cholagogue, diuretic, emollient, sedative, and for managing fever, hypertension, infections, and scrofula. Scientific evidence regarding its therapeutic properties remains limited and varied; some studies on maslinic acid suggest a potential partial restoration of antioxidant defenses in specific animal models of injury, while other research focuses on genetic diversity and tree resilience. No major safety issues or notable drug interactions have been recorded in the available data.

What the science says
- Genetic and phenotypic analyses of 'Mehras' olive accessions revealed moderate to high genetic diversity with clear clustering and variation in fruit and leaf traits.
- Maslinic acid treatment showed a partial restoration of antioxidant defenses and reduction in reactive oxygen species levels following testicular ischemia-reperfusion injury in rats.
- Genetic diversity analysis revealed a north-south split with Dhofar populations forming a distinct lineage among wild olive accessions from Oman's mountains.
- MICOSAT F® microbial biostimulant treatment led to increased growth and altered carbon and nitrogen metabolism in olive trees, potentially enhancing their climate resilience.
- The study found that adjusting olive paste pH during malaxation influenced oil yield, phenolic content, and quality parameters of virgin olive oil.
- The study highlights that olive leaf extract exhibits multiple beneficial effects, including anti-inflammatory and anti-tumoral properties, though its role as an adjunct therapy in pediatric oncology remains to be fully elucidated.
- Cultivar-dependent responses to foliar fertilization varied in fruit size, quality indicators, and mineral composition across different olive cultivars.
- The study found that olive cultivars respond differently to Xylella fastidiosa infection, with resistant LECCINO showing targeted gene activation while susceptible OLIVA ROSSA exhibits widespread but ineffective reprogramming.
Frequently asked questions
