What is this page for?

First and foremost: checking Stillingia 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 Stillingia 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
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 product contains one active ingredient: stillingia root extract, also known as Queen's Delight. It's a botanical extract from the root of the stillingia plant, traditionally used to support various body functions.

The product comes as a liquid for oral use.

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 Queen's Delight's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: supports healthy lymphatic system and digestion.
  • We looked for evidence on: Constipation, lymphatic function, digestive health.
  • The closest evidence on file: Queen's Delight is rated "Insufficient Reliable Evidence To Rate" for Constipation (Natural Medicines).

The evidence we hold on stillingia doesn't support a strong claim for any of its traditional uses. For bronchitis, constipation, gallbladder disease, and hemorrhoids, the safety and reliability of the evidence are insufficient to rate whether it works.

In plain terms: we don't have solid proof it helps with these conditions, and you shouldn't count on it as a primary treatment.

The evidence, ingredient by ingredient Queen's Delight

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.

Here's what matters: stillingia contains compounds that irritate your mouth, throat, and digestive tract, and there's very little modern safety data on it. Taking it by mouth can cause nausea, vomiting, and diarrhea at common doses.

In large amounts, it may also cause a burning sensation in your mouth and throat, painful urination, muscle aches, fatigue, sweating, skin rashes, cough, and low mood. Applied to the skin, it can trigger contact dermatitis, swelling, and inflammation.

Because of these irritant effects and the lack of safety information, the data advises against use during pregnancy and while breastfeeding. If you're pregnant, planning to become pregnant, or nursing, do not use this product.

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 ingredient we could check. Nonetheless, always confirm with your own doctor or pharmacist before starting any new supplement alongside your current medications.

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.

Stillingia is a traditional herbal remedy, but the evidence doesn't establish that it works for bronchitis, constipation, gallbladder disease, or hemorrhoids, and it carries real risks of stomach upset and skin irritation at recommended and higher doses. It's not safe in pregnancy or while breastfeeding.

If you're considering this supplement, talk with your doctor or pharmacist first to weigh whether it's right for your situation.

Stillingia by Pure Herbs: Common Questions

Does Stillingia by Pure Herbs interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Stillingia. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Stillingia 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.
Can I take this while I'm pregnant or breastfeeding?
No. The safety data advises against stillingia during pregnancy because of its irritant effects and lack of safety information—it's rated Possibly Unsafe to Likely Unsafe. It's also rated Possibly Unsafe while breastfeeding. If you're pregnant, planning pregnancy, or nursing, don't use this product. Talk with your doctor or pharmacist about safe alternatives.
What are the most common side effects?
When taken by mouth, the most frequent side effects are diarrhea, nausea, and vomiting. In larger doses, you might also experience a burning sensation in your mouth or throat, painful urination, fatigue, sweating, skin rashes, cough, and muscle aches. If applied to skin, it can cause contact dermatitis, swelling, and inflammation.
Does this actually work for bronchitis or constipation?
The evidence we hold is insufficient to say whether it works for bronchitis, constipation, gallbladder disease, or hemorrhoids. There's not enough reliable research to support those uses, so you shouldn't rely on it as a primary treatment for any of these conditions.
Why does the label warn to use it under professional guidance?
Stillingia contains compounds that irritate your digestive tract and skin, and there's very little modern safety data available. The caution is there because we don't have a lot of information on long-term use or safety in different people, so a pharmacist or doctor should be involved in deciding whether it's appropriate for you.
Is there any ingredient in this I should avoid if I take medications?
No interactions are documented in our data. However, that doesn't mean they can't happen—it just means formal studies haven't been done. Before you start, run this product and your current medications through the interaction checker on this page, and confirm with your doctor or pharmacist.
