Olive Leaf Tea

Whole Dried Olive Leaves • From the Blessed Olive Tree • Simple Herbal Infusion

The Blessed Olive Tree

The olive tree has a remarkable place in the Qur’an.

In Surah An-Nur, Allah refers to it as a “blessed olive tree” — شَجَرَةٍ مُّبَارَكَةٍ.

Allah also swears by the olive in Surah At-Tin:

“By the fig and the olive...”
— Qur’an 95:1

The Prophet Muhammad ﷺ also said regarding the olive:

Our Olive Leaf Tea comes from that same olive tree, using the whole dried leaves rather than an extract, powder, flavoring, or tea blend.

Why Olive Leaves?

The leaves of the olive tree naturally contain plant polyphenols, including oleuropein, along with compounds such as hydroxytyrosol and luteolin derivatives.

These olive-leaf compounds have attracted considerable scientific interest, particularly for their relationship to cardiovascular health, antioxidant activity, blood pressure, inflammation, and metabolic health.

Human research is strongest in the area of cardiovascular health — especially blood pressure.

Oleuropein & Olive Polyphenols

Oleuropein is one of the primary naturally occurring phenolic compounds found in olive leaves.

Olive leaves also contain other phenolic compounds, including hydroxytyrosol and several flavonoids.

These compounds have demonstrated antioxidant activity in laboratory research and are a major reason the olive leaf continues to receive scientific attention.

The amount present in a brewed cup naturally varies with the leaves, harvest, quantity used, water temperature, and brewing method — another reason we prefer not to treat whole-leaf tea as though it were a standardized supplement capsule.

Beyond Blood Pressure

Researchers have investigated olive leaf in several other areas of health.

Cholesterol & triglycerides: Some controlled human trials have reported improvements in total cholesterol, LDL cholesterol, and triglycerides after olive-leaf extract supplementation.

Blood sugar & insulin: Human studies have produced mixed but interesting findings. Some trials have reported improved insulin sensitivity or glucose-related markers, while newer research has not consistently reproduced those effects.

Inflammation: Controlled human research has reported reductions in several inflammatory markers after olive-leaf extract supplementation.

Antioxidant activity: Olive leaves contain a range of phenolic compounds with demonstrated antioxidant activity.

There is also laboratory research exploring antimicrobial and other biological properties of olive-leaf compounds, but those findings should not be interpreted as evidence that drinking olive-leaf tea treats infections or disease.

How to Brew

Whole-Leaf Olive Tea

Add 8–12 dried olive leaves to 8 oz of water.

Simmer gently for 10 minutes.

Strain and enjoy warm or iced.

A Simple Daily Tea

Olive Leaf Tea does not need to be complicated.

Brew a cup in the morning or evening and enjoy it as part of your regular tea routine.

Because research suggests olive leaf may influence blood pressure and blood-sugar regulation, people taking medication for either should be especially mindful of regular use.

Also Studied by Modern Researchers

The olive leaf has become particularly interesting to researchers because it contains a concentrated range of olive polyphenols.

One of the strongest recent studies was a 2025 randomized, double-blind, placebo-controlled trial involving 621 adults with hypertension. Standardized olive-leaf extract reduced 24-hour systolic blood pressure and was also associated with improvements in several metabolic and inflammatory measures.

A separate randomized trial in adults with pre-hypertension found reductions in both systolic and diastolic blood pressure along with improvements in several blood-lipid measurements.

Research on olive-leaf infusion itself is newer, but a recent six-week study in adults with hypertension also found meaningful reductions in blood pressure among those regularly drinking the infusion.

The research is promising, especially for cardiovascular health, but extracts and brewed whole leaves are not interchangeable doses.

For Sunnah Garden, the research is valuable — but the olive tree held significance long before the modern laboratory. Allah called it a blessed tree.

Storage

Store in a cool, dry place away from sunlight.

Keep the pouch sealed between uses to protect the dried leaves from moisture.
