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 liquid contains one active ingredient: olive leaf extract. You're getting a concentrated form of compounds from olive leaves, which is different from the whole olives or olive oil you might cook with.
The product also contains cane alcohol as an inactive ingredient to preserve and extract the plant material.
Does it work?
Not established
The evidence for olive leaf extract isn't established yet for the conditions listed in the data we hold—osteoporosis, indigestion (dyspepsia), exercise-related respiratory infections, shingles (herpes zoster), flu, and osteoarthritis all show insufficient reliable evidence to rate. That doesn't mean it doesn't work; it means researchers haven't run enough rigorous trials to say either way.
If you're considering this for one of those reasons, talk it over with your doctor to weigh what little evidence exists against other options.
How safe is it?
Well-documented data
Olive fruit and olive oil as foods are very safe, but concentrated supplements like this one are less studied, so use caution and get your doctor's approval before starting. Most people tolerate olive leaf extract well.
In trials, the most common side effects were headache and stomach discomfort. One person reported skin and acne, and note that olive tree pollen can trigger seasonal respiratory allergies if you're sensitive.
Meds to double-check
No known interactions
No interactions are documented for the ingredients we could check. That said, confirm with your own doctor or pharmacist that it's right for you before starting.
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.
This is a single-ingredient liquid with no documented drug interactions. It's not yet proven effective for any condition in our data, and concentrated olive leaf extract safety is less clear than the whole food.
If you're interested in trying it, run it by your doctor first—especially if you're pregnant, breastfeeding, or have respiratory allergies.
