Olive leaf is a versatile, broad-spectrum pathogen-fighter. It can help the body fight many conditions related to viruses, retroviruses, bacteria or parasites, including candida, influenza and the common cold. People who are particularly susceptible to colds and viruses may benefit from long-term use of olive leaf on a daily basis, especially during times of increased risk, with a short break every month.
Olive leaf has been well researched. Numerous studies show that enenolic acid, a component of oleuropein, the main active compound found in olive leaf, effectively inhibits the growth of viruses, bacteria, fungi and parasites. The most current research shows that olive leaf may block viruses by selectively blocking an entire virus-specific system in the infected host. Olive leaf also appears to have the 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.
As an antioxidant, Olive leaf extract helps protect blood vessels, and may protect the heart from coronary occlusion. When taken over an extended period of time, it may help reverse arteriosclerosis. Studies back to the 1960's and 1970's, mostly in Europe, found that oleuropein can lower blood pressure by dilating the blood vessels, and that it can increase blood flow in the coronary arteries, relieve arrhythmia and prevent intestinal muscle spasms.
The safety of olive leaf has been studied as well. A 1970 safety study on elenolic
acid by the Upjohn
pharmaceutical company found no toxic or other adverse side effects, even at very high doses.
