Olive trees have been the life blood of the Mediterranean for hundreds years. Proven to have many life enhancing properties, Indigo Herbs presents Olive Leaf Tea, Olive Leaf Tincture and Olive Leaf Powder. Additionally, you can choose from an array of Olive Leaf guest products. In the early 1900’s scientists isolated a bitter compound, “oleuropein”, that was thought to give the olive tree its disease resistance. It is now known that this compound is responsible for the many benefits of the Olive Leaf.
