Olive Leaf Tea: How to Make It (and What It’s Good For)
The fruit gets all the glory, but the silvery leaf of the olive tree has its own long history as a Mediterranean folk remedy — and it makes a pleasant, caffeine-free herbal tea you can brew at home in minutes.
People have brewed olive leaves around the Mediterranean for a very long time, valuing the tree as a whole rather than just its oil. The leaf is the same part of the plant that keeps an olive tree alive for centuries in hard, dry ground, and it carries some of the same antioxidant compounds that make good olive oil interesting. As a drink it is mild, green and grassy with a gentle bitterness — closer to a light herbal infusion than to black tea.
How to brew it
Use dried olive leaves if you can — fresh work, but dried keep well and steep more cleanly. Roughly a tablespoon of dried leaves per cup: pour over just-boiled water, cover the cup to trap the aromatics, and steep five to ten minutes — longer for a stronger, more bitter brew. Strain and drink. It takes honey, lemon or a sprig of mint kindly, and because it is naturally caffeine-free it is as happy last thing at night as first thing in the morning.
What is actually in it
The leaf’s headline compound is oleuropein, the same bitter polyphenol family found in the raw olive and in fresh olive oil. These are genuine antioxidants, and it is why the leaf has been used as a traditional tonic. But brewing a tea extracts only some of what is in the leaf, and in modest amounts — a cup of olive leaf tea is a pleasant source of a few plant polyphenols, not a concentrated dose of anything.
| Part used | The leaf (dried or fresh) |
|---|---|
| Key compounds | Oleuropein & related polyphenols |
| Caffeine | None |
| Taste | Mild, green, grassy, gently bitter |
| Steep | 5–10 minutes in just-boiled water |
| Pairs with | Honey, lemon, mint |
The honest health word
Here is where to keep your feet on the ground. Olive leaf and its compounds are genuinely interesting, and there is some research suggesting modest effects on things like blood pressure and antioxidant levels — but it is not a proven medicine, and the internet wildly overstates it. Enjoy olive leaf tea as a pleasant, antioxidant-bearing herbal brew, not a cure for anything. If you have a real condition, or you take medication for blood pressure, see a doctor rather than a teapot — concentrated leaf extracts in particular can interact with drugs. This is general information, not medical advice.
Making the most of it
- Dry your own leaves from an unsprayed tree if you have one — rinse, air-dry, store airtight.
- Steep longer for strength, shorter for a softer, less bitter cup.
- Blend it with mint or lemon verbena to round off the grassy edge.
- Treat it as a drink, not a supplement — for anything therapeutic, talk to a professional.
Olive leaf tea: common questions
Does olive leaf tea contain caffeine?
No. It is naturally caffeine-free, which makes it suitable at any time of day, including the evening.
What does it taste like?
Mild, green and grassy with a gentle bitterness. Steep it longer for a stronger, more bitter cup; honey, lemon or mint soften it nicely.
Is olive leaf tea good for you?
It supplies some antioxidant polyphenols and is a pleasant, calorie-free drink. But claims that it cures or prevents disease go far beyond the evidence. Enjoy it as a tea, not a medicine. This is general information, not medical advice.
Can I make it from fresh leaves off my tree?
Yes, if the tree is unsprayed. Rinse the leaves, and either use them fresh or air-dry them first; dried leaves steep more cleanly and keep for months.
Is it the same as olive leaf extract?
No. Extract is a concentrated supplement made from the leaf and is stronger; the tea is a mild infusion. The concentrated form is more likely to interact with medication, so treat it with more caution.
I am fond of olive leaf tea precisely because it is honest and modest — a nice grassy cup that uses the part of the tree we usually throw away. What I would gently steer you away from is the breathless marketing that surrounds it, promising it will fix your blood pressure, your immune system and everything else. It will not. Brew it because you like it, dry your own from a clean tree if you can, and keep the medicine cabinet and the teapot in separate rooms.
