olive leaf extract

High blood pressure raises the chance that a person will experience a stroke, a heart attack or kidney problems. It is no wonder, then, that many people are interested in controlling hypertension. Side effects from antihypertensive drugs can be troublesome for some individuals, though, and they search for alternatives. Can you lower your blood pressure with olive leaf extract?

Is Olive Leaf Extract Safe?

Q. Olive leaf extract seems to lower high blood pressure and have antibacterial and antifungal qualities. Is it safe to take?

A. Preliminary research in animals and humans suggests that olive leaf extract may indeed lower blood pressure (Nutricion Hospitalaria, July 2015; Journal of Medicinal Food, May 2016). In one study, researchers found that olive leaf extract (500 mg twice daily) was as effective as the blood pressure drug captopril at usually prescribed doses (Phytomedicine, Feb. 15, 2011). There has not been much research overall on the pros and cons of this dietary supplement, however.

As a result, it’s a bit difficult to determine if there are safety problems. One case report suggests that olive leaf extract might cause irritability and other psychological side effects (New Zealand Medical Journal, Apr. 1, 2016). Since the patient in the report was also taking other products, we are not completely certain that the olive leaf extract was responsible.

Lowering Blood Pressure Naturally:

There are a number of natural approaches that can help control hypertension, however. Many clinical trials have shown that the DASH diet (Dietary Approaches to Stop Hypertension) is effective for bringing blood pressure down (New England Journal of Medicine, April 17, 1997). The DASH diet emphasizes vegetables, fruit and low-fat dairy products and discourages excessive consumption of meats, processed foods, salt and sweets. If you would like more guidance on how to follow a DASH diet to control your blood pressure, you’ll find details in our book, The People’s Pharmacy Quick & Handy Home Remedies. You can also find information online at https://www.nhlbi.nih.gov/health/resources/heart/hbp-dash-week-dash-html

    Bottom Line. Been checking my Blood Pressure since Dec 1st. It’s the 19th today.

    I started on the 16th.

    It was 150 over 100 consistently within 5 of this up or down every time. I bought Olive leaf extract.

    In one day it was 130 over 80 and has been every day since.

    I don’t sell any olive leaf or make a dime off of anything.

    This is a fact.

    Well done, good article, thanks for sharing. I am studying the benefits of this plant, with focus on olive leaves and the surprise is that benefits are not only on blood pressure, but on cardiovascular health in general. Oleuropein and other polyphenols contained in olive leaves helps normal blood circulation, mantain a healthy level of lipids and sugars in the blood. Moreover they have antioxidant action and help to cleanse the liver. Some recent studies showed that there could be a connection bewteen psoriasis improvement and a treatment with olive leaves, it is really good news. Nature provides something incredible (that ancient people from Egypt and Greece knew very well) and that we forgot.

    I have read suggestions for lowering bp but is there something (other than activity) to raise heart rate and maintain it? Thanks.

    I have known people who have used olive leaf tisane for lowering things (nagalase) and bec. they have Lyme disease and other infections, it has hit them hard, while at the same time helping. So start slow and listen to your body.

    I was wondering what are the effects of brewing olive tree leaves as a tea: is it safe? If so, has it any health benefits?

    I have come to believe that the solutions are highly individualized and experimentation is required. I have used olive leaf extract 0.5g/day for other reasons for a long time but saw no change in BP when eliminating or doubling it. Chicken, turkey and beaf all have a large negative effect but salmon has none. After eliminating these, 2.5 mg Lisinopril is sufficient to reach a blood pressure of 125/80. Citrulline malate 0.75g elements a slight pounding sound of the pulse but no dose has much effect on my BP.

    If olive extract can lower your stress levels that are created by noxious chemicals so be it otherwise flush it.
