What is this page for?
First and foremost: checking Olive Leaf 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 Leaf by TerraVita
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 Glycerite Liquid Extract. It's a concentrated liquid form made from olive leaves.
The inactive ingredient is glycerin, which is used as a carrier and preservative.
Does it work?
Couldn't assess
The evidence we hold shows insufficient reliable data to rate olive leaf for any of the six conditions studied: osteoporosis, indigestion (dyspepsia), exercise-related respiratory infections, shingles (herpes zoster), flu, and osteoarthritis. That doesn't mean it doesn't work — it means the science isn't settled yet and we need more rigorous trials to know.
How safe is it?
Well-documented data
Olives and olive oil as food are very safe, but concentrated supplements like this one are less well studied. The safety data on concentrated olive leaf extract is limited, so talk with your doctor before starting it.
In trials, most people tolerated it well, though headache and stomach discomfort were reported by some. One person developed skin issues and acne.
If you have seasonal pollen allergies, be aware that olive tree pollen can trigger them.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. That's not a guarantee none exist — it just means concentrated olive leaf extract hasn't been studied for drug interactions yet.
If you take any prescription medications, run them through the checker on this page, and mention this supplement to your own doctor or pharmacist.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.
If you're interested in trying olive leaf for general wellness or one of the conditions mentioned, there's no documented interaction data to hold you back — but the evidence for its effectiveness isn't firm yet either. Since the safety profile of concentrated supplements is less known than whole olives or olive oil, clear it with your doctor or pharmacist first.
Check your specific medications against the interaction tool on this page before you start.
