3 health benefits of olive leaf extract you never knew about
It has been widely reported that of olive leaf extract can fight anti-cancer, lower cholesterol and boost immunity. But, these 3 other health benefits of olive leaf extract, you never knew about will surprise you.
The secret of olive leaf extract's many health benefits, is in its phenolic compounds, hydroxytyrosol and oleuropein. These compounds have been reported to prevent cold and flu, reduce blood pressure, inhibit leukemia cancer cells and help ease inflammatory bowel disease. But, there are many other health benefits of olive leaf extract, and here they are:
The first health benefit of olive leaf extract is that it acts as a natural anti – ageing remedy. This is because, maintenance of cellular homeostasis influences ageing and it is determined by several factors, including efficient proteolysis of damaged proteins. The ubiquitin-proteasome system is the major protein degradation pathway in the cell. Oleuropein has been observed to enhance proteasome activities in vitro more effectively than other known chemical activators, possibly through conformational changes of the proteasome. Moreover, continuous treatment of early passage human embryonic fibroblasts with oleuropein decreases the intracellular levels of reactive oxygen species (ROS), reduces the amount of oxidized proteins through increased proteasome-mediated degradation rates and retains proteasome function during replicative senescence.
The second health benefit of olive leaf extract is that it protects the brain. Animal studies have demonstrated that olive leaf extract improves blood-brain barrier permeability and brain edema in rat with experimental focal cerebral ischemia. Other studies have pointed out the positive impact of natural extracted polyphenols on the incidence of age-related disorders, such as dementia.
Phenol components from olives have been reported to have a direct antioxidant action on skin, especially oleuropein, which acts as a free radical scavenger at the skin level. Recently, a study suggested that the preventative effects of olive leaf extracts and oleuropein on chronic UVB-induced skin damage and carcinogenesis and tumor growth may be due to inhibition of the expression of VEGF, MMP-2, MMP-9, and MMP-13 through a reduction in COX-2 levels.
