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.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

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
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Olive product and its label doesn't state a use — see Olive's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

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.

The evidence, ingredient by ingredient Olive

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

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.

Olive Leaf by Woodstock Herbal Products: Common Questions

Does Olive Leaf by Woodstock Herbal Products interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Olive Leaf. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Olive Leaf contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What are the most common side effects?
Headache and stomach discomfort are the most common ones reported in trials. One person reported acne or skin issues. Overall, olive leaf extract seems well tolerated, but keep an eye on how you feel when you start.
Is this safe during pregnancy or while breastfeeding?
We don't have safety data on file for pregnancy or breastfeeding. Because concentrated olive leaf supplements are less well studied than olive oil and olives as food, talk with your doctor or pharmacist before taking this if you're pregnant or nursing.
Does olive leaf extract actually work for colds or flu?
The evidence isn't strong enough to say. We have insufficient reliable data to know whether it helps prevent or treat influenza. If you're interested in it, talk with your healthcare provider about what might work best for you.
What's the difference between this and olive oil I cook with?
Olive oil and whole olives as food are very safe and well studied. This supplement is a concentrated extract, and the safety of concentrated supplements is less well known, so it deserves more caution. Always check with your doctor before starting a concentrated supplement.
Does this contain alcohol?
Yes, this liquid form contains alcohol as an inactive ingredient. That's worth knowing if you avoid alcohol for any reason.
