Maintaining good cardiovascular health involves a combination of healthy lifestyle choices, including a balanced diet, regular physical activity, adequate sleep and not smoking. Alongside these habits, many people enjoy herbal teas such as Olive Leaf Tea as part of their everyday wellness routine.
Made from the leaves of the olive tree (Olea europaea), Olive Leaf Tea is naturally caffeine-free and contains naturally occurring plant compounds, including polyphenols such as oleuropein and hydroxytyrosol.
Naturally Occurring Plant Compounds
Olive leaves naturally contain several bioactive compounds that have attracted scientific interest over recent years. Among the most widely studied is oleuropein, a naturally occurring polyphenol that contributes to the unique composition of olive leaves. Researchers continue to investigate these compounds for their biological properties in laboratory and clinical settings.
What Does the Research Show?
A number of scientific studies have explored olive leaf extract and its naturally occurring compounds in relation to cardiovascular health.
Some clinical studies have investigated whether olive leaf extract may influence blood pressure or blood vessel function in certain groups of people. For example, a randomised controlled trial published in Phytotherapy Research reported that olive leaf extract supplementation was associated with reductions in blood pressure among individuals with borderline hypertension. Another clinical study published in the European Journal of Nutrition found that a phenolic-rich olive leaf extract supported healthy blood pressure in adults with elevated blood pressure.
Researchers have also explored the biological activity of oleuropein and hydroxytyrosol, with studies suggesting these naturally occurring compounds possess antioxidant properties that may help protect cells from oxidative stress. However, the overall body of evidence is still evolving, and scientists agree that further large-scale, high-quality human studies are needed before definitive conclusions can be drawn.
Importantly, these studies have generally examined concentrated olive leaf extracts rather than Olive Leaf Tea, and their findings should not be assumed to apply directly to tea consumed as a beverage.
Why People Enjoy Olive Leaf Tea
Many people choose Olive Leaf Tea because it is:
- Naturally caffeine-free
- Rich in naturally occurring polyphenols
- Smooth, refreshing and enjoyable throughout the day
- An easy addition to a varied and balanced diet
Enjoying Olive Leaf Tea
Whether enjoyed in the morning or as an evening herbal infusion, Olive Leaf Tea offers a refreshing alternative to caffeinated drinks and can be incorporated into a healthy lifestyle.
For the best flavour, steep one tea bag in freshly boiled water for 3–5 minutes and enjoy as desired.
Important Information
Although olive leaf compounds continue to be studied by researchers, there is currently insufficient evidence to conclude that drinking Olive Leaf Tea lowers blood pressure, improves cardiovascular health or prevents disease.
The scientific studies referenced primarily investigated olive leaf extract, which is more concentrated than Olive Leaf Tea and should not be considered equivalent.
Olive Leaf Tea should not be used as a substitute for prescribed medication, medical treatment or professional healthcare advice. If you have high blood pressure, cardiovascular disease, are pregnant or breastfeeding, or are taking prescription medicines (including medication for blood pressure, diabetes or blood thinning), consult your GP or another qualified healthcare professional before regularly consuming herbal products.

The scientific studies referenced relate primarily to olive leaf extract or individual compounds naturally found in olive leaves, rather than Olive Leaf Tea itself. Because extracts are significantly more concentrated than herbal tea infusions, the findings of these studies should not be assumed to apply directly to drinking Olive Leaf Tea.
Olive Leaf Tea should be enjoyed as part of a healthy, balanced diet and lifestyle. Individual results may vary. If you have an existing medical condition, are pregnant or breastfeeding, or are taking prescription medication, seek advice from your GP or another qualified healthcare professional before making significant changes to your diet or consuming herbal products regularly.
