Olive Leaf Comparable to Captopril for Blood Pressure
Blood pressure readings decreased significantly in both the captopril and olive leaf extract groups
Keeping high blood pressure in check is an important foundation of health, as hypertension is related to several serious conditions, including coronary heart disease, heart failure, stroke, and kidney failure. Some people manage their condition effectively with a medications and dietary habits, but researchers are always exploring more options. Olive leaf(Olea europaea) extract is an herbal extract suspected of having beneficial effects on high blood pressure, and researchers designed a study to compare its effects to captopril, a blood pressure medication known as an ACE-inhibitor.
Comparing olive leaf to captopril
Researchers randomly selected 148 men and women to take either 500 mg of olive leaf extract or 12.5 to 25 mg of captopril twice daily for eight weeks. Participants were instructed to follow a low-fat, low-salt diet, getting no more than 2,400 mg of sodium per day.
Study participants were 25 to 60 years old and had Stage 1 high blood pressure, defined as having a systolic blood pressure (top number) of 140 to 159 mm Hg and a diastolic pressure of 90 to 99 mg Hg. Blood pressure measurements were taken weekly throughout the study and blood levels of cholesterol and fat in the blood (triglycerides) were measured at the start, at four weeks, and at the end. After eight weeks, the researchers noted that:
Holding the line against high blood pressure
This study suggests olive leaf extract may be as effective as captopril for treating Stage 1 high blood pressure, and may improve triglyceride and cholesterol levels as well. If you are managing hypertension, keep the following in mind before making a change to your self-care program:
Eat to relieve the pressure
Following a healthy diet is an essential part of an effective blood pressure management program--in some people it's enough to bring blood pressure under control all by itself. For most, the Dietary Approaches to Stop Hypertension (DASH) diet is a good place to start. To meet DASH diet guidelines, every day aim for:
