    • Species native to Syria and naturalized in southern France, Corsica and Algeria. It requires full light, looking for dry soils, with warm exposures; vigorous tree that can live for a very long time, with very compact and very homogeneous wood. The wild olive tree called Oleaster was spontaneous throughout the Mediterranean basin. The limits of the olive tree are above all the cold of the North or the excessive drought (Egypt) but its possible areas can be extended to California, South Africa and Australia

    Properties

     

    Plant properties

     

    • Leaf :
      • Hypotensive (modest action) [3] , but a study shows identical efficacy of 500 mg of standardized extract of olive leaves twice a day to that of 12.5 to 25 mg of Captopril twice a day [4] , average decrease of 5 to 13 mm Hg [5]
      • Coronaro-dilator, increases coronary flow, cardiac protector by combining antioxidant, antihypertensive, hypoglycemic, hypocholesterolemic [10] , antiatherogenic [11] , protector of myocardial function by an anti-inflammatory, antiatherosclerotic, anti-ischemic, hypolipidemic effect [12] , protection of myocardial cells (cardiomyocytes) [13] , protector of vascular function [14]
      • Bradycardic antiarrhythmic ( oleanolic acid ) by beta-adrenergic antagonist effect, negative chronotropic and positive inotropic effects [15]
      • Cardioprotective, the ethanolic extract of olive leaves, which contains oleuropein , hydroxytyrosol , verbascoside , luteolin and quercetin exerts a protective effect on cardiomyocyte viability greater than that of each of these phenolic compounds [16]
      • Inhibition of platelet aggregation [17]
      • Spasmolytic
      • Antioxidant [18] , [19]
      • Hypocholesterolemic, hypotriglyceridemic and anti-diabetic (especially the oleaster variety ) [20] , hypoglycemic in rats [21]
      • Antidiabetic by inhibition of alpha-amylase and alpha-glucosidase ( luteolin and its derivatives luteolin-7-O-β-glucoside and luteolin-4′-O-β-glucoside ) [22] , hypoglycemic by oleuropeoside at a dose of 16 mg/kg, resulting from two mechanisms: potentiation of glucose-induced insulin release and increased peripheral glucose absorption [23] , antidiabetic properties in rats (leaf extract with doses of 0.1, 0.25, 0.5 g/kg of body weight for 14 days) higher than those of glibenclamide (600 microg/kg) [24] , oleuropein and oleanolic acidare involved in the anti-diabetic effect of olive leaves [25]
      • Improves insulin sensitivity and lowers the risk of developing metabolic syndrome [26]
      • Antibacterial and antifungal [27] by phenolic derivatives
      • Nephroprotective [28]
      • Thyroid stimulant (?) pituitary-independent activity [29]
    • Olive oil :
      • Anti-inflammatory (similar to ibuprofen) [30]
      • Inhibition of platelet aggregation [31]
      • Decreases oophorectomy-induced osteoporosis in rats [32]

    Regulations

     

     

    Possible side effects and precautions for use
