Generic Name: Olives


Herbs & Supplements


Olea europae, Oleaceae (family).


Olive leaves come from the olive tree (Olea europae), a native of the Mediterranean. Although olives and olive oil are used as foods, olive leaf is primarily used medicinally or as a tea.

Laboratory studies indicate that olive leaf may be beneficial as an antibacterial, antifungal, antiviral, or antioxidant. However, there is insufficient evidence in humans to support the use of olive leaf for any indication.

In the Middle East, olive leaf tea has been used for centuries to treat sore throat, coughs, fevers, high blood pressure, cystitis (bladder infection), and gout (foot inflammation), and to improve general health. Olive leaf poultices have been applied to the skin to treat dermatological conditions, such as boils, rashes, and warts.

However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.


Avoid in individuals with a known allergy or hypersensitivity to olive, olive leaf (Olea europaea), its constituents, or related members of the Oleaceae family.

Side Effects and Warnings

There are very few reports of olive leaf and its adverse effects. There are currently no high quality studies available on the medicinal applications of olive leaf. Use cautiously in patients taking antiviral medications as olive leaf may have antiviral properties.

Pregnancy and Breastfeeding

Olive leaf is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.
