Olive extracts help protect the brain and central nervous system from the destruction brought on by strokes and age-related degenerative conditions such as Alzheimer’s and Parkinson’s diseases.50 They accomplish this by suppressing inflammation and reducing the damage done by oxidative stress. In acute brain injuries such as those caused by a stroke or trauma, damaging processes such as oxidative stress occur within minutes of the original event—and, ironically, are worsened by the return of normal blood flow to the area.50,51 Researchers found a number of positive effects in animals that were pre-treated with olive leaf extract and then induced with a stroke. Compared with untreated animals, the treated animals experienced a sharp reduction in markers of oxidation and an increase in normal cellular antioxidant systems.52,53 Microscopic examination of brain tissue revealed a similar decline in injury to brain cells and up to a 55% decrease in the volume of dying brain tissue.50 Similar results are shown in experimental spinal cord injury in animals pretreated with oleuropein.53 Olive leaf extracts offer similar protection for neurodegenerative diseases. Oxidative stress occurs more gradually in neurodegenerative diseases. However, the effects add up over a lifetime, producing inflammation and other changes that result in the accumulation of abnormal proteins that interfere with brain function and kill neurons. Olive leaf extracts help prevent these abnormal proteins from assembling into the neurofibrillary tangles seen in the brains of people with Alzheimer’s and similar diseases.54-56
Olive leaves and their extracts have long been used in the Mediterranean as folk remedies for arthritis. Now, scientific evidence has proven that olive leaf extracts can in fact interfere with the development of several different kinds of arthritis, including gout, rheumatoid arthritis, and osteoarthritis.
Gout is caused by the accumulation of uric acid crystals in joints, the byproducts of impaired recycling of DNA and RNA in cells. In a mechanism identical to that of allopurinol (the gold standard drug therapy for gout), oleuropein prevents the buildup of uric acid by inhibiting xanthine oxidase, the enzyme responsible for converting DNA and RNA into uric acid.57
Oleuropein has also been found to help prevent and treat symptoms of rheumatoid arthritis. When administered at the earliest sign of arthritis in animal models, oleuropein prevented symptoms from developing and also produced marked improvement in the microscopic appearance of joint tissue from affected animals. When administered after arthritis was fully developed, there was significant improvement in inflammatory changes to joints, compared with untreated animals.58
Oleuropein had similar benefits on osteoarthritis. In animal models of this degenerative joint disease, olive leaf extract improved joint swelling, improved the microscopic appearance of joint tissue, and prevented the production of inflammatory cytokines.59
