HelloPharmacist Scorecard of Olive Leaf by Oregon's Wild Harvest

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: organic olive and olive leaf powdered extract. Both come from the olive plant and are included in the same supplement to give you the benefits of different parts of the tree.

The capsules also contain pullulan and maltodextrin as inactive ingredients—these are common fillers and binders that help hold the product together.

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 effectiveness of olive and olive leaf extract hasn't been established in reliable studies for any of the conditions this product may target—osteoporosis, upset stomach (dyspepsia), shingles, flu, exercise-related respiratory infections, or osteoarthritis. Right now the evidence is insufficient to say whether it works for these uses.

If you're thinking about using it for a specific health concern, talk it over with your doctor or pharmacist first.

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 seems to be well tolerated overall. The most common side effects from trials were headache and stomach discomfort.

One person reported skin and acne issues. Olive tree pollen can trigger seasonal respiratory allergies if you're sensitive.

The caution here is that olives and olive oil are very safe as foods, but concentrated supplements are less well studied than whole foods. There's no safety data on file for pregnancy and lactation.

If you're pregnant, nursing, or thinking about starting this while either applies to you, talk with your doctor or pharmacist first to see if it's right for you.

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the ingredients we checked in this product. That said, run your specific medications through the interaction checker on this page or ask your pharmacist to confirm there's nothing between them and olive leaf before you start.

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.

This product may appeal to you if you're looking for an olive-based supplement and want something with no documented drug interactions. If you're pregnant, nursing, or have a respiratory allergy to olive tree pollen, check with your doctor or pharmacist first.

Because the evidence for its effectiveness isn't established yet, have that conversation with your doctor or pharmacist about whether it makes sense for your situation.

Olive Leaf by Oregon's Wild Harvest: Common Questions

Does Olive Leaf by Oregon's Wild Harvest 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 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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. Olive leaf extract seems well tolerated overall, though one person reported skin and acne. If you're allergic to olive tree pollen, this could trigger seasonal allergy symptoms.
Is it safe to take while pregnant or breastfeeding?
There's no safety data on file for pregnancy or lactation. Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant, planning to get pregnant, or nursing.
Does this actually work for arthritis, flu, or other conditions?
The evidence isn't there yet—all the conditions this product is marketed for show insufficient reliable evidence to say whether olive or olive leaf actually works. If you're considering it for a specific health reason, talk with your doctor or pharmacist first.
How is this different from eating olives or cooking with olive oil?
Olives and olive oil as foods are very safe, but this is a concentrated supplement—and concentrated supplements aren't studied as well as whole foods. If your doctor approves, the supplement form may let you get a higher dose than food alone.
