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
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.

Pure Herbs Tart Cherries contains one active ingredient: sour cherry fruit extract. This is a concentrated form of the whole fruit, designed to deliver the compounds present in tart cherries in a liquid format.

There are no inactive ingredients listed.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Sour Cherry's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: sleep support and heart health.
  • We looked for evidence on: Insomnia, Exercise-induced muscle soreness, Gout, Hypertension, Sleep quality, Arterial health — and 2 related terms.
  • The closest evidence on file: Sour Cherry is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness (Natural Medicines).
  • Also on file: Sour Cherry is rated "Insufficient Reliable Evidence To Rate" for Hypertension, Insomnia, Gout.

The evidence is mixed. Sour cherry extract is rated possibly effective for athletic performance — meaning there's some evidence it may help, though it's not conclusive.

For attention, thinking, muscle soreness after exercise, respiratory infections after exercise, and fibromyalgia, the evidence we hold is insufficient to say whether it works or doesn't. If you're interested in tart cherry for one of those later uses, talk to your pharmacist about what the current research landscape looks like.

The evidence, ingredient by ingredient Sour 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.

Tart cherry is generally well tolerated when you eat the whole fruit or drink its juice. Concentrated supplements like this liquid are less studied, so the facts recommend using caution.

The most common side effects in people who use concentrated products are abdominal pain, stomach upset, loose stools, and general tiredness. A small number of people reported skin reactions possibly tied to cherry allergy.

Because safety data for supplement doses is limited, it's wise to start with a small amount and see how you feel.

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 sour cherry fruit extract. That doesn't mean interactions can't occur — just that we hold no records of them.

Check your exact medications with the tool on this page or ask your pharmacist to be sure.

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.

If you're looking to try tart cherry for athletic performance, this concentrated liquid is worth considering — the evidence is suggestive, though not iron-clad. Start slowly to watch for stomach upset.

Pregnant or breastfeeding? The fruit itself is rated likely safe, so a conversation with your pharmacist or doctor about this particular product makes sense.

And do run your medications through the checker on this page before you start.

Tart Cherries by Pure Herbs: Common Questions

Does Tart Cherries by Pure Herbs interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Tart Cherries. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Tart Cherries 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.
Will this upset my stomach?
Tart cherry concentrate can cause abdominal pain, loose stools, and general stomach upset in some people — especially at higher doses. A clinical study found that about 29% of children taking concentrated tart cherry juice twice daily reported belly pain. Start with a small amount and see how you feel.
Can I take this if I'm pregnant or breastfeeding?
The fruit itself is rated likely safe in pregnancy and lactation. Since this is a concentrated supplement rather than whole fruit, though, the safety data is thinner. Talk with your doctor or pharmacist about whether it's right for you during pregnancy or while nursing.
What is sour cherry extract actually for?
Sour cherry is possibly effective for athletic performance — there's some evidence it may help, though it's not definitive. For muscle soreness, attention, thinking, respiratory infections after exercise, and fibromyalgia, we don't have enough evidence yet to say whether it works.
Is this ingredient safe in general?
Tart cherry as a whole fruit or juice is generally well tolerated. This is a concentrated supplement, though, and concentrated products are less studied. The facts advise caution because supplement-dose safety data is limited. If you notice side effects like stomach pain or loose stools, dial back the amount or stop and talk to a pharmacist.
Are there any fillers or other ingredients mixed in?
No — the product facts list no inactive ingredients, so you're getting the sour cherry fruit extract and nothing else.
