What is this page for?
First and foremost: checking Olive against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.
Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Olive by Herb Pharm
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: olive leaf extract. Olive leaf has been used traditionally and studied for a range of purposes, though the evidence for most of them remains preliminary.
The liquid form also contains cane alcohol as an inactive ingredient.
Does it work?
Not established
The evidence for olive leaf extract is insufficient to rate its effectiveness for the conditions it's been studied in — osteoporosis, indigestion (dyspepsia), exercise-related respiratory infections, shingles, flu, and osteoarthritis. That means the data we hold doesn't support a clear claim that it works for any of these.
If you're considering it for a specific reason, talk with your pharmacist about what the current research actually shows.
How safe is it?
Well-documented data
Olive as a food and olive oil are very safe, but concentrated supplements like this one are less studied. The extract itself appears to be well tolerated in the trials we have data for.
The most common side effects reported were headache and stomach discomfort. One person reported acne, and people with seasonal allergies to olive tree pollen may react.
Because the long-term safety of concentrated olive leaf supplements isn't well known, your doctor should give the go-ahead before you start.
Meds to double-check
No known interactions
No interactions are documented in our data for olive leaf extract. That doesn't mean none exist, so it's still worth checking your exact medications with the search tool below or with your pharmacist before you start.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.
Olive leaf extract is generally well tolerated, but the evidence for what it actually does is weak across the board. If you're considering it, talk with your pharmacist first — especially since concentrated supplements are less studied than the food forms most of us eat.
It's a reasonable conversation to have, but it shouldn't replace proven treatments for the conditions you're managing.
