The 5 Best Olive Leaf Teas for Immunity & Heart Health (2025 Guide)

Important Safety Note

Olive Leaf Tea can lower blood pressure naturally. If you are already taking medication for hypertension or blood thinners, consult your doctor before adding this to your daily routine.

Long before it was a health trend, Mediterranean cultures brewed the leaves of the olive tree to fight fever and infection. Today, science backs up the tradition: Olive Leaf is packed with Oleuropein, a powerful antioxidant that supports heart health and immune function.

However, pure Olive Leaf is naturally bitter. We have tested the top brands to find the ones that balance potency with drinkability, from pure organic cuts to refreshing mint blends.
