Olive Leaf (Olea europea)

Olive Leaf Overview:

Olives are a well known food item enjoyed all over the world. Many people are unaware however, that the leaves of the olive tree have usefulness as a medicinal agent.

In modern times, olive leaves are mostly marketed as antibacterial agents. This is true, but they are not the best antibacterials out there, and the fad of using olive leaf religiously to prevent colds and flus is likely jsut a transient trend.

What olive leaf is very good for however, is cardiovascular health. Oleorupin, as well as some of the other iridoid glycosides present in the leaf have been found to produce mild ACE inhibition, dilate the coronary arteries, and lower blood pressure.
