Olive Leaf Extract
Olive leaf extract is made by extracting the dried leaves of the olive tree, Olea europaea, with a solvent such as ethanol; it is produced both as a liquid extract and as a dry extract. Like the leaves, it contains oleuropein: in one studied dry extract, oleuropein made up 18–26% of the weight.[1]
Research and use
Olive leaf is traditionally used to promote the elimination of water by the kidneys in mild water retention. This traditional use covers only the leaves, as herbal tea or powder, not extracts made from them. Clinical studies are few, and results for one extract cannot be applied to other olive leaf preparations.[1]
Safety
No side effects have been reported with olive leaf preparations. Because data are lacking, olive leaf medicines are intended only for adults and are not recommended in pregnancy or while breastfeeding.[1]
