Olive is a tree. People use the oil from the fruit and seeds, water extracts of the fruit, and the leaves to make medicine.

Olive oil is most commonly used for heart disease, high cholesterol, and high blood pressure.

In foods, olive oil is used as a cooking and salad oil. Olive oil is classified, in part, according to acid content, measured as free oleic acid. Extra virgin olive oil contains a maximum of 1% free oleic acid, virgin olive oil contains 2%, and ordinary olive oil contains 3.3%. Unrefined olive oils with more than 3.3% free oleic acid are considered "unfit for human consumption."
