Olive Leaves: A Natural Remedy with Powerful Health Benefits
What Are Olive Leaves?
Olive leaves come from the olive tree (Olea europaea), a plant native to the Mediterranean region. While olives and olive oil are well-known for their health benefits, the leaves of the olive tree have also been used for centuries in traditional medicine across Europe, North Africa, and the Middle East.
Key Compounds in Olive Leaves
The health-promoting effects of olive leaves are primarily due to their rich concentration of bioactive compounds, especially:
- Oleuropein – a powerful antioxidant and anti-inflammatory compound unique to olive trees.
- Hydroxytyrosol – another strong antioxidant known for heart and brain protection.
- Flavonoids – such as luteolin and apigenin, which help reduce oxidative stress.
- Triterpenes – with antimicrobial and anti-cancer properties.
