Olive oil is used to prevent heart attack and stroke (cardiovascular disease), breast cancer, colorectal cancer, rheumatoid arthritis, and migraine headache.
Some people use olive oil to treat constipation, high cholesterol, high blood pressure, blood vessel problems associated with diabetes, and pain associated ear infections, arthritis, and gallbladder disease. Olive oil is also used to treat jaundice, intestinal gas, and meteorism (swelling of the abdomen due to gas).
Some people also use olive oil to boost bacteria in the gut and as a “cleanser” or “purifier.”
Olive oil is applied to the skin (used topically) for earwax, ringing ears (tinnitus), pain in the ears, lice, wounds, minor burns, psoriasis, stretch marks due to pregnancy, and for protecting the skin from ultraviolet (UV) damage after sun exposure.
In foods, olive oil is used as a cooking and salad oil.
In manufacturing, olive oil is used to make soaps, commercial plasters and liniments; and to delay setting in dental cements.
Olive oil that is mixed with a gas called ozone (ozonated olive oil) is promoted for everything from bee stings and insect bites to bacterial and fungal skin infections to cancer. The Food and Drug Administration (FDA) allows the use of ozone to fight bacteria on food, including meat and poultry, but the food industry has been slow to adopt it. Ozone is extremely unstable and must be produced on site. Topical olive oil products that are claimed to contain ozone are unlikely to remain stable during shipping. There are no clinically proven medical uses of ozone or ozonated olive oil. Antibacterial agents that are applied to the skin are a better choice.
