Olive Oil - Research
In one study, researchers were able to show that a diet rich in olive oil intake significantly correlated to a decrease in blood pressure in healthy adult volunteers.8 Another investigation indicated that a reduced fat diet high in extra virgin olive oil allowed for lower daily dosages of antihypertensive medications.9
Recently, externally applied olive oil combination products have been studied for the treatment of diaper rash.10
Olive oil has been used historically for relief of intestinal gas, for lubrication of the intestines, and as a mild laxative.5 Externally, olive oil has been applied to soothe minor burns and dry skin. In combination with other products, olive oil has been used in the treatment of stretch marks due to pregnancy, as well as for firming the breasts.5
