Olive leaf is the leaf of the olive tree (Olea europaea) was first used medicinally in Ancient Egypt. It is gaining recognition as a powerful defender against sickness and numerous scientific studies have been conducted to investigate the extracts beneficial properties. The reported benefits of olive leaf extract range from promoting increased energy, to supporting the cardiovascular system and the immune system.Research suggests that olive leaf extract may be a true anti-viral compound because it appears to selectively block an entire virus-specific system in the infected host. This appears to offer healing effects not addressed by pharmaceutical antibiotics. Olive leaf's broad killing power includes an ability to interfere with critical amino acid production for viruses; an ability to contain viral infection and/or spread by inactivating viruses by preventing virus shredding, budding or assembly at the cell membrane; the ability to directly penetrate infected cells and stop viral replication.Olives are native to Asia Minor and Syria, but are cultivated in Mediterranean countries and also Chile, Peru and South Australia. Olive leaf was first used medicinally in Ancient Egypt and was a symbol of heavenly power. It was also used to mummify pharaohs. More recent knowledge of the olive leaf's medicinal properties dates back to the early 1800s when pulverised leaves were used in a drink to lower fevers. A few decades later, green olive leaves were used in tea as a treatment for malaria.Mr. Health Olive Leaf Extract is Manufactured in the USA, under strict quality control conditions, and is standardized to a minimum of 6% Oleuropein.Many people who live stressful lives or who may be particularly susceptible to colds and viruses may benefit from long-term use of olive leaf as a preventive agent. Some patients have expressed other unexpected benefits of olive leaf, including improved psoriasis, normalisation of heart beat irregularities, diminished cravings, less pain from hemorrhoids, toothaches and chronically achy joints.Early references to the olive leaf as medicine can be found in the Bible: "The fruit thereof shall be for meat, and the leaf thereof for medicine." (Ezekiel 47:12) Today, olive leaf is becoming increasingly well-known and appreciated outside of olive-growing regions, as science on its benefits expands. One of the primary compounds in olive leaf, a substance called oleuropein, has attracted scientific attention since the early 1900s. An iridoid by definition, oleuropein exhibits antibacterial, antiviral and antifungal activity, and is useful for fighting various types of internal infections. Oleuropein also appears to increase the body’s production of thermogenin, a substance that helps us to burn fat more efficiently. Studies conducted in Milan have shown that this compound is a potent antioxidant, inhibiting the oxidation of lipids in the blood, and lowering the risk of cardiovascular disease. In fact, the antioxidant activity of olive leaf is higher than that of green tea. A significant body of science shows that antioxidant compounds derived from plants provide profound health benefits, and help to reduce the risk of many chronic and degenerative diseases. Olive leaf extract also acts as an anti-inflammatory. Like oxidation, inflammation is a key factor in chronic and degenerative diseases.
