A study looked at 20 sets of identical twins with “borderline” hypertension — blood pressure that is above the optimal level of 120/80, but below the cutoff of 140/90 used to diagnose high blood pressure. One member of each twin pair was given tablets containing olive leaf extract, while the other received no supplements but did get lifestyle advice on lowering blood pressure.
After eight weeks, supplement users taking 1,000 mg of olive leaf extract per day showed a substantial dip in their blood pressure overall, and lowered levels of LDL or “bad” cholesterol. The twins who received no supplements showed no significant change in their blood pressure and a smaller improvement in cholesterol.
Habitat : Barberry is native to central and southern Europe, northwest Africa and western Asia; it is also naturalised in northern Europe, including the British Isles and Scandinavia, and North America. In the United States and Canada, it has become established in the wild over an area from Nova Scotia to Nebraska, with additional populations in Colorado, Idaho, Washington State, Montana, and British Columbia. Although not naturalised, in rural New Zealand it has been widely cultivated as a hedge on farms. It is cultivated for its fruits in many countries.
