|What is it?|
|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 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 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.”
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.
Olive leaf is used for treating viral, bacterial, and other infections including influenza, swine flu, the common cold, meningitis, Epstein-Barr Virus (EBV), encephalitis, herpes, shingles, HIV/ARC/AIDS, and hepatitis B. Olive leaf is also used for pneumonia; chronic fatigue: tuberculosis (TB); gonorrhea; fever; malaria; dengue; “blood poisoning” (bacterial infections in the bloodstream); severe diarrhea; and infections in the teeth, ears, and urinary tract, and infections following surgery. Other uses include high blood pressure, diabetes, hay fever, improving kidney and digestive function, and increasing urine flow.
Water extracts of olive fruit pulp are used for rheumatoid arthritis and osteoarthritis.
|Is it Effective?|
|Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.The effectiveness ratings for OLIVE are as follows:|
|Possibly Effective for…|
- Lowering cholesterol in people with high cholesterol levels. Using olive oil in the diet instead of saturated fat can significantly reduce total cholesterol levels. However, some research suggests other dietary oils such as sunflower and rapeseed (canola) might reduce “bad” low-density lipoprotein (LDL) cholesterol and another type of cholesterol called apolipoprotein B better than olive oil.
- Lowering blood pressure in people with high blood pressure. Adding generous amounts of extra virgin olive oil to the diet and continuing with the usual treatments for high blood pressure can significantly improve blood pressure over 6 months. In some cases, patients with mild to moderate high blood pressure can actually lower their dose of blood pressure medication or even stop taking medication altogether. However, don’t adjust your medications without your healthcare provider’s supervision. Taking olive leaf extract also seems to lower blood pressure in patients with high blood pressure.
- Reducing the risk of heart diseases and heart attack. Replacing saturated fats in the diet with olive oil can reduce risk factors for heart disease and stroke, including reducing blood pressure and cholesterol. Adding olive oil to the diet seems to help prevent a first heart attack. Some research shows a high dietary intake of olive oil (54 grams/day) can reduced the risk of first heart attack by 82% when compared with a low intake of 7 grams of olive oil or less per day.
The FDA now allows labels on olive oil and on food that contains olive oil to state that limited, but not conclusive evidence, suggests that consuming 23 grams/day (about 2 tablespoons) of olive oil instead of saturated fats may reduce the risk of heart disease.
- Decreasing the chance of getting breast cancer and colorectal cancer. However, there is no evidence olive oil can help treat these conditions.
|Possibly Ineffective for…|
- Softening earwax.
- Treating pain associated with ear infections.
|Insufficient Evidence to Rate Effectiveness for…|
- Diabetes. Compared to polyunsaturated oils such as sunflower oil, olive oil in a Mediterranean-type diet might reduce the risk of “hardening of the arteries” (atherosclerosis) in people with diabetes. But more research is needed.
- Osteoarthritis. Developing research shows that taking a freeze-dried water extract of olive fruit decreases pain and increases mobility in people with osteoarthritis.
- Rheumatoid arthritis. Some research suggests that people whose diet includes a high amount of olive oil have a lower risk of developing rheumatoid arthritis. However, early research shows that taking a water extract of olive fruit does not significantly improve symptoms of rheumatoid arthritis.
- Migraine headache.
More evidence is needed to rate olive for these uses.
|How does it work?|
|Fatty acids in olive oil seem to decrease cholesterol levels and have anti-inflammatory effects. Olive leaf and olive oil might lower blood pressure.|
|Are there safety concerns?|
|Olive oil is LIKELY SAFE when taken appropriately by mouth or applied to the skin. Olive oil can be used safely as 14% of total daily calories. This is about 2 tablespoons (28 grams) daily.Olive oil taken by mouth is well-tolerated. When applied to the skin, delayed allergic responses and contact dermatitis have been reported.|
There is insufficient reliable information available about the safety of olive leaf, although so far olive leaf and fruit pulp have not been associated with significant side effects in clinical studies.
Olive trees produce pollen that can cause seasonal respiratory allergy in some people.
Special Precautions & Warnings:
Pregnancy and breast-feeding: Not enough is known about the safety of using olive products during pregnancy and breast-feeding. Don’t use amounts greater than the amount commonly found in foods.
|Are there any interactions with medications?|
