Andres Koch, Barlean’s, noted olive leaf is also useful for customers already fighting a cold or flu, as it can help cut the duration of illness. Acknowledging the growing awareness of this lesser-known botanical remedy, Koch said, “It’s just a matter of time before the olive leaf benefits will be understood in the mainstream population."
According to Koch, medicinal use of olive leaves dates back to ancient Egypt and is referenced by Hippocrates and now in modern medical texts. “The olive tree has an impressive longevity history," he said, noting many trees are recorded to live longer than 1,000 years. “Why? Because the miracle tree possesses unusually high antibacterial, anti-viral and anti-fungal properties to help defend itself against any environmental threats." Also, olive leaf is also highly antioxidant, equal to or greater than many well-known superfruits.
He suggested a tablespoon a day of Barlean’s Olive Leaf Complex to support the immune system, while for those in the midst of fighting bacteria, virus or fungi, double or triple daily doses are recommended.
Given the mounting research linking the Mediterranean diet with health and longevity, it is no surprise more olive-based products are hitting the immune-health market. “There’s no doubt consumers have been swayed by the mounting studies linking a lower incidence of heart disease and cancer to a Mediterranean dietary guideline," said Robert Crea, Creagri, which makes an olive water-based product called Olivenol®. He explained olive water—olives are 50-percent water and 15-percent to 20-percent oil—is rich in polyphenols, including the highly antioxidant and protective hydroxytyrosol. “Olive polyphenols provide antioxidant, free-radical fighting capabilities that help consumers maintain more optimal health, and provide an immune-boosting ingredient to ward off colds and flu," he said. A dose of two to four tablets daily is recommended to deter any immune system compromise that could lead to a cold or flu.
