Latin Name: Olea europaea
Herb Class/Action:

Medicinal Properties:
Antimicrobial and Immune Support: Olive leaf is highly effective against a range of pathogens including bacteria, viruses, and fungi. It is often used in formulas for colds, flu, Epstein-Barr virus (EBV), and chronic infections.
Cardiovascular and Blood Pressure Support: Olive leaf supports healthy blood pressure and circulation by relaxing blood vessels and reducing arterial stiffness. It may also help reduce LDL cholesterol and improve overall heart function.
Antioxidant and Anti-inflammatory: Rich in polyphenols like oleuropein, olive leaf combats oxidative stress and systemic inflammation, protecting tissues and supporting cellular health.
Blood Sugar and Metabolic Health: Olive leaf may help regulate blood sugar levels and insulin sensitivity, making it a supportive herb for individuals with prediabetes, type 2 diabetes, or metabolic syndrome.
Liver and Detoxification Support: Olive leaf supports gentle detoxification and liver health by reducing inflammation and aiding in the elimination of pathogens and toxins from the body.
In the Garden:
Olive trees are evergreen and native to the Mediterranean region. They thrive in full sun and well-drained, sandy or rocky soils with low humidity. Mature trees are drought-tolerant and long-lived. Leaves can be harvested year-round but are most potent in the spring and early summer. Prune regularly to encourage airflow and healthy growth.
Culinary Uses:
While not commonly used in culinary dishes, olive leaf is prepared as a bitter herbal tea or decoction and is sometimes infused into vinegars or tinctures. It pairs well with lemon balm, rosemary, or mint to balance its bitterness.
Precautions:
Olive leaf is generally safe when used appropriately. It may lower blood pressure and blood sugar, so individuals on related medications should monitor closely and consult a healthcare provider before use. Occasionally, a "die-off" or Herxheimer reaction may occur in sensitive individuals due to its strong antimicrobial action—start with low doses and increase gradually. Not recommended during pregnancy without professional supervision.
