Since ancient times, the benefits of olive oil and lemon have been known — lauded as both nutritious food and effective folk remedies. In 400 B.C.E., the renowned Greek physician and "Father of Medicine," Hippocrates, prescribed olive oil for more than 60 medical conditions, calling it the "Great Healer." He regarded citrus, such as lemon, to be a great energizer for the body, counteracting phlegm and lethargy. Together, these two powerhouse remedies bring time-tested benefits that also stand up to modern scientific research.
Healing Benefits of Olive Oil
Hippocrates wasn't the only ancient Greek singing the praises of olive oil; Homer, who authored great works, including "The Iliad" and "The Odyssey," called the substance "liquid gold," and today's scientists tend to agree.

Olive oil contains a host of health-building ingredients, including vitamin E, monounsaturated fat, oleic acid, bioavailable plant phenols, anti-inflammatories and antioxidants. The oil is a staple ingredient in the Mediterranean Diet, recommended by doctors for a host of chronic conditions, including heart disease, depression, dementia, fatty liver disease and more.
Recent studies confirm what Hippocrates knew long ago. A 2018 study review by the Sapienza University of Rome examined worldwide results that confirm olive oil's benefits as a vasodilatory nutrient, anti-inflammatory and antioxidant that reduces stress on the cardiovascular system.
Another 2018 study by the Center for Gender-Specific Medicine showed it plays a positive healing role in chronic inflammatory diseases such as rheumatoid arthritis, multiple sclerosis, lupus, inflammatory bowel disease and psoriasis.
Lemon's Anti-Disease Benefits
A 2017 study by the University of Pisa confirmed Hippocrates' theory from thousands of years ago: Citrus fruits, such as lemon, bergamot, lime and orange, are helpful in preventing and curing several aspects of cardiovascular disease due to their flavonoid content.
Lemon is also helpful for digestion and, when concentrated into its essential oil form, can kill off dangerous microbes such as Listeria monocytogenes according to a 2017 study published in BioMed Central. The Journal of Oral Hygiene and Health reports that a 30 percent solution of lemon juice in water is as effective as an oral rinse made with povidone iodine when it comes to antibacterial activity. But lemon juice went one step further by inhibiting bacteria from reproducing after the rinse.

It's been found helpful for conditions as diverse as kidney stones, cancer, liver disease and weight loss.
