Botanical Overview of the Olive Tree

Cultivation of the olive tree (Olea europaea) dates back to prehistoric times. It is a sturdy evergreen tree or shrub that can tolerate coastal climate conditions with sandy soil and lots of sunshine. The tree is native to the Mediterranean, Asia, and Africa.

It is slow-growing and often seen with a thick twisted trunk. It has silver-green oblong leaves and small white delicate flowers. The olive fruits it bears are one of the most extensively harvested crops on this planet.

Oleuropein, the plant's key medicinal ingredient that helps protect the tree from insects and microbes, was first researched in the 1960s for its healing properties.

Therapeutic Uses of Olive Leaves

In recent years Oleuropein’s benefits have attracted attention for a variety of benefits alleviating modern lifestyle diseases and contributing to a longer, healthier life. Scientific studies have evaluated its antioxidant, antimicrobial, anti-inflammatory qualities as well as its ability to help strengthen the cardiac and immune systems.

Its carotenoid and chlorophyll contents may be useful in improving skin health, reducing macular degeneration of the eye, and strengthening cognitive function.

Studies have researched the following benefits of olive leaf supplements and its constituents among others.

  1. Immune system support with antimicrobial, anti-fungal, anti-candida, and antiviral applications.
  2. Healthy cardiovascular and metabolic system functions, including blood pressure, cholesterol, and blood sugar levels.
  3. Antioxidant and detoxification effects for healthy cells.
  4. Skin strengthening, protective, and healing qualities to reduce the signs of aging and sun damage and to promote clear skin.
  5. Eye and vision support by protecting against age-related macular degeneration.
  6. Liver protective, gastroprotective, and endocrine system supporting activities.

The Historical Significance of Olive Leaves

Olive leaves are known to symbolize both victory and peace. In Greek mythology, there is a story about the gods Athena and Poseidon presenting gifts to the city of Athens in a contest.

Poseidon slammed his spear into the dry ground and created a spring. Athena planted an olive tree. It was determined that Athena’s gift was superior, and she won control of Athens.

Crowns of olive branches were also awarded to the winners of the ancient Olympic Games. Today’s universal peace symbol of a dove carrying an olive branch has roots in a biblical scene.

The story goes that after 40 days and 40 nights of storms, the dove returned to Noah bearing an olive branch and peace returned to the land. In 1949, Picasso’s now famous Dove of Peace was chosen for the poster of the first World Peace Congress.

In Summary…

The olive tree is ancient, and its leaves have been used as an herbal remedy for millennia. It offers a large span of wellness benefits related to its antioxidant, antimicrobial, and anti-aging potential.
