Queen's Delight + Cefaclor
Cefaclor brand names: Ceclor CD, Ceclor.
We found no known interaction between Queen's Delight and Cefaclor in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Cefaclor states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Queen's Delight and Cefaclor
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Cefaclor and Queen's Delight in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Queen's Delight at all — not against Cefaclor, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Some Cefaclor Products Have a Food Rule — Queen's Delight Should Not Break It
At least one FDA label for a product containing Cefaclor says to take it with food. If you take Queen's Delight on an empty stomach out of habit, keep them separate — and take Cefaclor with a meal where the label says to.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Cefaclor products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.
DOSAGE AND ADMINISTRATION The absorption of cefaclor extended-release tablets is enhanced when it is administered with food.
From the Dosage and Administration section of the FDA label we read for Cefaclor — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›
A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.
What Cefaclor Is Prescribed For, and What Queen's Delight Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Cefaclor is a prescription medicine with approved uses on its FDA label. Queen's Delight is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Cefaclor is prescribed for: Cefaclor treats a range of bacterial infections. The capsule and oral suspension forms are used for ear infections (otitis media), lower respiratory tract infections including pneumonia, strep throat and tonsillitis, urinary tract infections (including kidney infections and bladder infections), and skin and skin structure infections. The extended-release tablet form of Cefaclor is approved for a narrower set of uses: acute bacterial flare-ups of chronic bronchitis, strep throat and tonsillitis, and uncomplicated skin infections. Not all infections approved for the capsule or suspension are approved for the extended-release tablet — your prescriber will choose the right form for your infection.

Bronchitis studied, not established Queen's Delight has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Queen's Delight for bronchitis
Although there has been interest in using oral queen's delight for bronchitis, there is insufficient reliable information about the clinical effects of queen's delight for this condition.
Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Cefaclor on your own; if you are taking Queen's Delight for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Cefaclor page
“The entries worth understanding before any others on this cefaclor (Ceclor) page are the kidney risks and charcoal. Cefaclor is a cephalosporin antibiotic, typically a short course for ear, sinus, throat, or skin infections, and two herbs here, Siberian cocklebur and asarabacca, can damage the kidneys on their own, so pairing either wi…”

About Queen's Delight
What is Queen's Delight?
- Skin conditions and 'blood purifying'
- Chronic skin eruptions (eczema, psoriasis)
- Syphilis and other infections (historical use)
- Sore throat and respiratory complaints
- Constipation (as a laxative)
Queen's Delight (Stillingia sylvatica) is a traditional North American herb once used as a 'blood purifier' and for skin and throat problems. There is very little modern scientific evidence to support these uses, and the plant contains irritating compounds that can cause significant side effects. Talk with a pharmacist or doctor before trying it.
Stillingia sylvatica · Euphorbiaceae · Root and dried root (sometimes the root resin/oil) · Dried root, tincture, fluid extract, capsules, and as part of traditional herbal blends
An interaction check asks whether these two react with each other — it does not ask whether Queen's Delight is a good idea for someone in your situation. Here is what our Queen's Delight record says about it on its own.
Queen's Delight: dosing
There is no well-established, standardized dose for Queen's Delight. Traditional herbalists used small amounts of the dried root, tincture, or fluid extract, but these doses were not tested in modern clinical studies.If you choose to use a product, follow the directions on the label and do not exceed them. Because the herb can be irritating, starting low and using it only briefly is wise.

Cefaclor Is Linked to Lower Levels of 7 Nutrients
Natural Medicines records Cefaclor as a medicine that can lower these. This is not an interaction with Queen's Delight — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
