Olive leaf tea, especially powdered olive leaf tea may have several potential health benefits, such as helping to lower blood pressure, lower cholesterol, help prevent weight gain, protect against heart disease, help protect against some cancers and decrease someone’s risk of developing type 2 diabetes.
The olive leaves contain high amounts of polyphenols, most importantly oleacein, oleuropein and hydroxytyrosol.
See the Research page for more specific information on the mechanisms for these potential health benefits.
