Drug & supplement interaction

Queen's Delight + Raltegravir

Raltegravir brand name: Isentress.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Queen's Delight and Raltegravir 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 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 Raltegravir

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 Raltegravir 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 Raltegravir, 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.

What to actually watch for

No Interaction Found — But Data Suggests Queen's Delight and Raltegravir May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • Low mood Worth acting on reported in 10.5% of FDA reports for Raltegravir Additional detail

Reported for Queen's Delight but not commonly for Raltegravir: sweating, a skin rash, swelling and itching.

Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

From our pharmacist’s overview on the Raltegravir page

“For someone taking raltegravir (Isentress) to keep HIV suppressed, a steady drug level is what blocks rebound and resistance, and this list deserves genuine vigilance. The lone major-rated entry is activated charcoal, which can soak up the medicine in the gut and cut what reaches your blood.”

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.
