Olive Leaf Olivir may be a true antiviral since it selectively blocks an entire virus-specific system. It has been shown to directly stimulate phagocytosis, an immune system response in which cells ingest microorganisms and foreign matter and it has no impact on the friendly intestinal microorganisms. In 1993, when a weaker form of Olivir was tested on six herpes patients with active herpes lesions, all six subjects reported significantly better results than they had previously using the medication Acyclovir. One of the components of olive leaf, oleuropein, is reported to be useful for lowering blood pressure, increasing blood flow in the coronary arteries, relieving arrhythmia and preventing intestinal spasms.

A hydroethanolic processing method using selected extracts of the olive plant, has been developed to produce Olivir, a natural supplement proven useful for combating a wide range of viral and bacterial infections.
