What to look for in an Olive leaf extract


The Olive tree is regarded as one of the oldest cultivated trees in the world and provides a valuable source of Olive leaves. Olive leaves were first thought to be used medicinally by the Ancient Egyptians and the Olive tree was called “The Tree of Life” in the Bible. Traditionally, Olive leaf is used in Western herbal medicine (WHM) to promote general health and wellbeing.

Active compounds of Olive Leaf
The primary active constituents of Olive leaf are the antioxidant compounds known as oleuropein and hydroxytyrosol, considered to be responsible for the majority of the leaf’s therapeutic activity. Antioxidant activity reduces free radical damage in the body. Olive leaf also contains other valuable compounds, including rutin, apigenin, luteolin and important nutrients, such as selenium, chromium, vitamin C, iron, zinc, beta-carotene and a broad variety of amino acids. These additional compounds, in conjunction with oleuropein and hydroxytyrosol, work synergistically to support the overall therapeutic effect of Olive leaf.

Olive leaf is traditionally used in WHM to:

  • Support immune system health and function
  • Relieve mild fevers and reduce body temperature
  • Support cardiovascular system health and function
  • Temporarily relieve mild fluid retention

    What to look for in an Olive leaf extract:

    1. Standardised oleuropein and hydroxytyrosol
    Look for an Olive leaf extract that has been standardised for both oleuropein and hydroxytyrosol. The higher the oleuropein and hydroxytyrosol content, the higher the therapeutic benefit. A standardised Olive leaf extract guarantees that each and every dose of Olive leaf contains the stated amount of oleuropein and hydroxytyrosol.

    2. Ethanol and water extraction process
    A water and glycerine extraction process allows a pure alcohol-free extraction, while maximising the active components of the Olive leaf. In the past, Olive leaf extracts typically used a water and ethanol extraction process but with the advent of new technology, a purified water and glycerine extraction is possible, leaving an alcohol-free extract high in oleuropein and hydroxytyrosol. An alcohol-free extract means that Olive leaf is suitable for the whole family, as well as for consumers looking to avoid alcohol extracts for personal reasons.
