It may also help to lose weight, improve skin health, manage arthritis, and avoid or heal herpes breakouts.

Olive leaf extract is derived from the leaves of the olive tree and has been used medicinally for thousands of years. The key ingredient in olive leaf extract (OLE) is oleuropein, along with other flavonoids and polyphenolic compounds, that deliver a host of health benefits for those who regularly consume this extract, regardless of what form it comes in. [1]

Olive trees, scientifically known as Olea europaea, are some of the oldest cultivated plants. Native to the Mediterranean region, olives have been naturalized in dozens of countries and are highly valued for the oil in its fruit. [2]

Unlike olive oil, the olive leaf extract is acquired from the leaves themselves and can be prepared at home, if you have the time and willingness. Otherwise, this extract is commonly available in supplement form. There are various other ways to benefit from the dense nutrient value of olive leaves, such as teas or tinctures, but they aren’t as efficient or potent when it comes to this extract’s health potential. You can also consume them in the form of olive leaf tea.

However, before we get started with the benefits, it is important to note that scientific research to ascertain them is limited and most of the studies available on olive leaf extract are based on animal models. Human studies are required to understand its health-promoting benefits better.

Benefits

Let’s take a look at the most important health benefits of olive leaf extract:

(Video) Olive Leaf Extract Benefits & Side Effects

May Lower Blood Pressure

Research has shown that olive leaf extract may help lower blood pressure and may reduce the risk of hypertension. A 2011 study published in the Phytomedicine Journal shows how when people with stage 1 hypertension were administered with 500 mg of olive leaf extract for 8 weeks, they showed a significant reduction in their blood pressure, similar to another group of people who were given 12.5–25 mg of captopril, a blood pressure medication, twice a day, for the same duration. This goes to show that olive leaf extract has the same impact on lowering stage 1 hypertension as captopril. These effects, in turn, may help reduce strain on the cardiovascular system and lower your risk of coronary heart diseases. [3] [4]

May Have Anti-Aging Properties

The potential antioxidant abilities of this extract can help to protect the skin and protect against UVB radiation that can speed up the aging process. Additionally, the antioxidants will help soothe oxidative stress in the upper layers of the skin, which can minimize the appearance of wrinkles, age spots, and other blemishes. Regular use can also inhibit the degradation of structures in the inner layer of the skin and speed up the proliferation of skin cells [5]

May Improve Cardiovascular Health

The compounds found in olive leaf extract can prevent the oxidation of LDL or bad cholesterol that causes deposition of plaque in arteries and leads to a higher risk of coronary heart diseases. These plaques may increase the risk of atherosclerosis and other cardiovascular conditions. As evidenced in the 2015 animal study, daily supplementation of olive leaf extract may help reduce triglyceride levels, further reducing risk factors in the development of heart diseases. [6] [7]

May Regulate Diabetes

Olive leaf extract has the potential to help reduce a person’s risk of developing type 2 diabetes. A study published in the Journal of Medicinal Foodindicates how effective olive leaf extract is in starch indigestion and absorption, which further results in better regulation of blood sugar levels. If you are at high risk for diabetes or have already been diagnosed, this extract may be helpful to maintain steady blood sugar levels. [8]

May Improve Cognitive Function

Olive leaf extract offers protection against neurodegenerative diseases such as Alzheimer’s and Parkinson’s diseases as per a study conducted by a team of Spanish researchers. Regular use of this supplement has also been prescribed for people who have suffered from strokes or other acute brain injuries, as it can reduce oxidative stress and potentially help improve cognitive performance. [9] [10]

May Have Analgesic Qualities

If you regularly suffer from pain, the potentially analgesic qualities of olive leaf extract may help to reduce that discomfort and inhibit the signaling of nerve receptors from the site of the injury. A study published in The Saudi Dental Journal showed how a mouth rinse containing olive leaf extract helped reduce oral inflammation in patients after chemotherapy. A 2012 in-vivo animal research also shows the possible effects of olive leaf extract in reducing the swelling and resultant pain in arthritis. [11] [12]

In terms of reducing inflammation in the body, people have been taking this extract for sore joints and muscles for generations. Hydroxytyrosol, a compound found in olive leaves, “has antioxidant, anti-bacterial and anti-inflammatory properties, ” says a study published in the Journalof Ethnopharmacology. Though more studies are needed, this likely makes it an effective remedy for chronic pain of other types as well, particularly those from old injuries. [13]

May Boost Immune System

The immunomodulatory effects of olive leaf extract along with a potentially high level of antioxidants help reduce oxidative stress and relieve any strain on the immune system. A study published in the Alternative Medicine Review shows that olive leaf extract has some potential activity against the influenza virus. It shows how gargling with olive leaf tea is likely to relieve us from symptoms of a sore throat by potentially reducing the viral infection and inflammation. [14] [15]

May Aid in Weight Loss

A different 2016 study showed that rats given this extract had lower body weight and improved metabolic profiles. Though more studies are needed, this research indicates that olive leaf extract shows promising results in the fight against obesity. [19]
