9 Proven Olive Leaf Benefits listed by AgroWeb

1. Lowers Blood Pressure

A 2011 study evaluated the effectiveness of olive leaf extract in comparison to Captopril, a medication that is given to patients with hypertension or high blood pressure. Five hundred milligrams of olive leaf extract, taken twice daily for eight weeks, significantly reduced systolic and diastolic blood pressure.

While both olive leaf extracts and Captopril were able to prevent high blood pressure levels, the olive leaf treatment also resulted in a reduction of triglyceride levels (reducing bad cholesterol); plus, there are a number of possible side effects when taking Captopril, including dizziness, loss of taste and dry cough.

2. Improves Cardiovascular Health

Olive leaves have been used as an herbal tonic to support cardiovascular function for thousands of years. High doses of olive leaf extract have been shown to help reduce elevated LDL-cholesterol levels and assist in the maintenance of normal blood pressure. The principal products of oleuropein that is present in olives and olive leafs, have both been linked to reduction of coronary heart disease and certain cancers.

3. Diabetes
Olive leaf extracts have hyperglycemic effects, meaning they reduce blood sugar levels in the body. The olive leaf also controls blood glucose levels in the body. The polyphenols in the olive leaf plays a vital role in delaying the production of sugar, which causes inflammatory diseases like diabetes. One study proved this when olive leaves suppressed the elevation of blood glucose in volunteers after they were consumed starch.

4. Reduces the Risk of Cancer

Olive leaves show an important role as a natural cancer treatment because of its ability to stop the angiogenic process, which stimulates the growth of tumors.

Using olive leaf infusions or extracts is a safe and effective way to treat Alzheimer’s disease naturally.
