Quince Ingredients & Drug Interactions
by Pure Herbs
What is this page for?
First and foremost: checking Quince against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.
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 Quince by Pure Herbs
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 product contains one active ingredient: quince fruit extract from fresh quince. It's a liquid formulation designed to deliver the compounds naturally present in quince fruit.
Does it work?
Moderate evidence
The evidence for quince is limited. For gastroesophageal reflux disease (GERD) — that burning sensation when stomach acid backs up into your throat — quince is rated possibly effective, meaning there's some evidence it may help, but more research is needed.
For allergic rhinitis (hay fever), asthma, pregnancy-related nausea and vomiting, and peptic ulcers, there isn't enough reliable evidence in our data to say whether it works.
How safe is it?
Some data gaps
Quince as a whole food is generally well tolerated. The catch is that concentrated supplements like this one haven't been well studied, so we don't have a clear picture of how safe high-dose extracts are.
There's also not enough reliable data on quince supplements during breastfeeding, so caution is advised if you're nursing. If you're pregnant or breastfeeding, talk with your doctor or pharmacist before taking this.
Meds to double-check
No known interactions
No interactions are documented in our data for quince fruit extract. That said, run your specific medications through the search tool on this page or ask your pharmacist to be thorough.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.
If you're looking at quince for GERD, there's some evidence it may help — but the research is still thin. Since concentrated quince extracts haven't been thoroughly tested for safety, this is a 'talk it over first' supplement.
Check with your doctor or pharmacist before you start, especially if you're pregnant, nursing, or taking any medications.
