Olea Europaea has anti-thrombophilic and anti-viscous properties that aid in regulating the circulation of blood by making it less viscous. Its prescription is restricted to sclerotic patients whose intellectual functions have diminished considerably. This remedy will have some therapeutic value only when prescribed exclusively according to biological data. As opposed to Rosmarinus Officinalis, Olea Europaeas action on cholesterol metabolism dysfunction is not as clear. However, Olea Europaea s action on blood viscosity and its antisclerotic action is superior to that of Rosmarinus Officinalis. Olea Europaea and Rosmarinus Officinalis are equally effective for cholesterol and thrombosis.
