History/Folklore: In the 1800’s the leaves were crushed and used in a drink to lower fevers. Olive leaf tea was used to treat malaria. There is no pharmaceutical or other plant better able to fight the incredible number (over 600 identified types) of viral infections that olive leaves. Olives and olive oil are also famous for their nutritional value and heart and immune enhancing properties.

The active ingredient in olive leaves is oleuropein. It is often extracted from olive oil and olives. It is highly bitter and has powerful anti-inflammatory and antioxidant properties. Oleuropein is showing signs in research for lowering blood pressure and increasing blood flow to coronary arteries. Oleuropein also contributes to the leaf’s ability to decrease the chance and effects of cardiovascular disease, type II diabetes, cancer, and Alzheimer’s and Parkinson’s diseases.

Olive oil is considered one of the “good” fats among plant oils. It is the highest in monounsaturated fat, which does not oxidize in the body and is therefore not carcinogenic. The oil has anti-inflammatory and antioxidant properties that help prevent strokes, cancer, and heart disease, and also promote bone health.

Typical dosing is 500 to 1,000 mg of olive leaf extract for daily use as a supplement. As a condensed form of the oil, the extract makes an excellent choice for maximizing the healing properties found in olive oil. Olive leaf is known to be one of the world’s best antiviral herbs available. Olive leaf extract is used to treat colds and flu, shingles, urinary tract infections, chronic fatigue syndrome, osteoarthritis, osteoporosis, HIV, allergies, diabetes, and diarrhea.

The most ancient evidence of olive cultivation has been found in Syria, Palestine, and Crete. Farmers in ancient times believed that olive trees would not grow well if planted too far away from the sea. First used in ancient Egypt as a medicine and as an ingredient in embalming, they were a symbol of heavenly power.

Olives have long been considered sacred. The olive branch is a symbol of abundance, glory, and peace. The leafy branches have been used as offerings to deities and as emblems of benediction and purification. They were used to crown the victors of games and even wars. Olive oil was burnt at the first Olympic Games to create the “Eternal Flame” and its leaves were used to crown the victors.

The ancient Greeks smeared olive oil on their skin and hair as a matter of good grooming and health. Olive woods were used to fashion the most primitive Greek cult figures, called “xoana”, referring to their wooden material; the olive wood preserved the figures for centuries.

In an Athenian foundation myth, Athena won the patronage of Attica and Poseidon with the gift of the olive. The olive was sacred to Athens and appeared on Athenian coins.

Theophrastus, the 4th-century father of botany, said olive trees attained an age of about 200 years, mentioning that the very olive tree of Athena still grew at the Acropolis. This tree was said to still be there in the 2nd century AD when Pausanias recorded seeing it.

In Islam the olive is praised as a precious fruit that the Quran notes as being a “Blessed Tree, that is neither eastern nor western and gives Light” Muhammad is reported as having said, “Take oil of olive and massage with it, it is a blessed tree” (Sunan al Darimi, 69:103). The olive tree, its olives, and oil also play an important role in the Bible as place names (for example, the Mount of Olives) and in ceremonies as a symbol of peace and purification.

Olives are often harvested in the green to purple stage (black is the fully ripe and mature stage). Ferrous sulfate is often added to artificially turn the green olives to purple, to black for canning.

In China, olives are also used for making an oil resin varnish known as “elemi” and for printing inks. Being green they symbolize life. In Traditional Chinese Medicine, olive oil is considered to be both sweet and sour at a neutral temperature.

A wine-like beverage can be brewed from green olives.
