Olive Leaf Ingredients & Drug Interactions

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 Woodstock Herbal Products
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 liquid contains a single active ingredient: olive leaf extract. Olive leaf has been used traditionally for various purposes, though the evidence behind most of those uses remains limited.
The product also contains alcohol as an inactive ingredient.
Does it work?
Couldn't assess
The evidence for olive leaf extract is insufficient to establish whether it works for osteoporosis, indigestion (dyspepsia), exercise-induced respiratory infections, shingles (herpes zoster), flu (influenza), or osteoarthritis. We simply don't have reliable clinical data on file to say one way or the other for any of these conditions.
How safe is it?
Well-documented data
Olive leaf extract appears to be well tolerated overall. The most common side effects in trials were headache and stomach discomfort; one person in a trial reported skin issues and acne.
If you have seasonal allergies to olive tree pollen, that's something to be aware of. The main caution here is that while olives and olive oil as everyday foods are very safe, concentrated supplements like this one are less well studied, so check with your doctor before starting if you have health concerns.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check in this product.
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 curious about olive leaf extract and have no major health conditions or medication conflicts, this product is generally well tolerated. That said, the evidence for what it actually does isn't established.
Talk to your pharmacist or doctor before you start, especially if you're pregnant, nursing, or take regular medications.
