Uses Of Olives
No plant has served humankind quite like the olive. Long before it was a health headline it was food, fuel, medicine, soap and light. Even today the tree wastes almost nothing — the fruit, the leaf, the pressing residue and the wood all earn their keep.
We think of the olive as oil and a bar snack, but the tree has always been a whole economy in itself. In the ancient Mediterranean its oil was food and cooking fat, yes, but also lamp fuel, machine lubricant, the base of soap, a cosmetic, a medicine and a sacred anointing oil. That breadth is the real reason the olive spread with every civilisation that touched the sea — it was not a luxury but an all-purpose staple. Most of those uses survive in some form, and the tree still gives far more than the bottle on your table suggests.
| Part of the tree | What it gives | How it’s used |
|---|---|---|
| The fruit (pressed) | Olive oil | Cooking, finishing, and historically soap, lamps, medicine |
| The fruit (whole) | Table olives | Brined, dry-cured, stuffed, on pizza and in stews |
| The leaf | Olive-leaf extract | A traditional remedy; sold today as capsules and teas |
| The pressing residue | Pomace | Solvent-extracted for low-grade oil, then burned as fuel |
| The wood | Olivewood | Turning, carving, inlay, kitchen ware — dense and figured |
Cooking: still the heart of it
Oil remains the olive’s great gift to the kitchen. Among cooking fats it is unusual in having enough flavour to stand in for butter, and it is largely monounsaturated — the more stable kind of fat. It is more heat-tolerant than people assume, too, so a good oil handles a sauté or a roast without drama, though its finest use is always raw, where the flavour survives. Table olives run a close second: thousands of tonnes vanish onto pizzas and into stews, salads, tapenades and, of course, a martini. If you are switching from butter, remember you generally need a little less oil by volume than the butter it replaces.
Leaf, pomace and the no-waste tree
Beyond the fruit, the olive keeps giving. Olive-leaf extract, rich in a compound called oleuropein, has a long folk history and a busy modern shelf in health shops; the evidence is thinner than the marketing, so treat the bolder claims with care. The pomace — the crushed skins, pulp and stones left after pressing — is squeezed for a last, low-grade oil and then dried and burned as an efficient fuel, often to heat the very mill that produced it. Little is thrown away.
Olivewood: the beautiful by-product
When an old tree finally comes down, its timber is treasure. Olivewood is dense and hard, with a fine, straight grain streaked in cream and warm brown — no two pieces alike. It turns and carves beautifully and takes a lovely polish, which is why it becomes bowls, boards, utensils and inlay rather than furniture; it is slow-grown, scarce and pricey compared with commercial timber, so it is used where its figure shows. A good olivewood board is, in a sense, the last gift of a tree that gave oil for a century first.
- Oil is the main event — flavourful, mostly monounsaturated, more heat-tolerant than people think, best raw.
- Table olives are the second great use — brined, cured, stuffed, everywhere from pizza to martini.
- Olive-leaf extract has a long folk history but modest evidence — be wary of big claims.
- Pomace becomes low-grade oil and then clean-burning fuel; olivewood becomes prized carved ware.
Uses of olives: common questions
What is olive oil used for besides cooking?
Historically it was lamp fuel, lubricant, soap base, cosmetic, medicine and anointing oil. Today cooking dominates, but olive oil still appears in soaps and skincare.
Can you fry with olive oil?
Yes. It is more heat-tolerant than many assume and handles sautéing and roasting well, though its flavour is best appreciated raw or in gentle cooking.
What is olive-leaf extract?
An extract from olive leaves, rich in oleuropein, with a long traditional-remedy history. It is sold as capsules and teas, but the scientific evidence is more limited than the marketing suggests.
What is olive pomace used for?
The residue left after pressing is solvent-extracted for a low-grade oil, then dried and burned as fuel — often to heat the mill itself.
Why is olivewood so prized?
It is dense and finely figured with cream-and-brown streaks, so it carves and polishes beautifully. Slow-grown and scarce, it is used for bowls, boards and utensils rather than bulk furniture.
People forget the olive was never just oil — it lit lamps, greased machines, made soap and medicine, and even now the tree wastes almost nothing. Cook with the oil for flavour and use it raw where it counts; enjoy the table fruit; but take the olive-leaf ‘cure’ shelf with a pinch of salt, because the marketing runs well ahead of the evidence. And if you ever get the chance to own an olivewood board, take it : that dense, streaked grain is the final gift of a tree that poured out oil for a hundred years first.
