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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Supports a healthy respiratory system.
  • We looked for evidence on: Cough, Bronchitis, Respiratory health.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

We hold no effectiveness ratings for Black Cherry Bark Extract in our data, so we can't tell you whether evidence supports its use for any particular purpose.

The evidence, ingredient by ingredient Wild Cherry

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.

Wild cherry bark is generally considered safe in the small amounts found in over-the-counter cough products. However, the plant contains compounds that can break down into cyanide, especially in large doses — and this is a genuine concern.

Taking large amounts can cause cyanide poisoning, which can be fatal. A documented case involved a woman who drank roughly 300 grams of wild cherries steeped in alcohol; she developed headache, nausea, vomiting, confusion, severe difficulty breathing, and went into a coma before recovering.

The safety data advises against using this product while pregnant or breastfeeding because there isn't enough information to know it's safe. Because of the cyanide risk, avoid large amounts of this extract altogether.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Wild Cherry.
  • The most serious interaction on file is rated Moderate.
  • For scale: 644 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Black Cherry Bark Extract may slow how your liver clears drugs metabolized by the CYP3A4 enzyme (Moderate severity). This hasn't been reported in actual patients yet, but if you take statins, antifungals, or any other medication your doctor has warned about mixing with grapefruit, check it here before you start.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This is a single-ingredient liquid, so it's straightforward — but the real question is dose. Tiny amounts in a cough drop are one thing; larger amounts of this extract carry a genuine cyanide toxicity risk.

Talk with your pharmacist about how much you're planning to take and whether it's right for you. Pregnant people and nursing parents should skip it.

Black Cherry Bark Extract1 drug type · 643 drugs

Cytochrome P450 3A4 (Cyp3A4) Substrates

In vitro research suggests that wild cherry can inhibit cytochrome P450 3A4 (CYP3A4) enzymes. Theoretically, wild cherry might increase levels of drugs metabolized by CYP3A4. However, so far, this interaction has not been reported in humans.
Some drugs metabolized by CYP3A4 include lovastatin (Mevacor), ketoconazole (Nizoral), itraconazole (Sporanox), fexofenadine (Allegra), triazolam (Halcion), and others.

Wild Cherry Bark by Pure Herbs: Common Questions

Does Wild Cherry Bark by Pure Herbs interact with any medications?
Yes. Based on its ingredients, Wild Cherry Bark has a known interaction with 643 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Wild Cherry Bark 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.
How much of this extract is safe to take?
The safety data says wild cherry bark is generally okay in small amounts — like what you'd find in commercial cough products. Avoid large amounts because the plant contains compounds that can produce cyanide, and we don't have good information on exactly what dose crosses that line. Your pharmacist can help you figure out a safe amount for what you're trying to do.
Can I take this while I'm pregnant or breastfeeding?
The safety data advises against it while breastfeeding. For pregnancy, there isn't enough safety information on file, so you'd need to talk with your doctor or pharmacist about whether it's right for you personally.
What are the side effects?
In large amounts, wild cherry can cause cyanide poisoning — the serious kind. Symptoms include headache, nausea, vomiting, confusion, and severe difficulty breathing. This is rare with tiny doses but a real risk with larger amounts. That's why the safety notes warn against using large amounts of this extract.
Does this actually work for what I want to use it for?
We don't have effectiveness ratings for Black Cherry Bark Extract in our data, so I can't tell you from our records whether the evidence supports its use. That's a good question to bring to your pharmacist along with the dose question.
