Drug & supplement interaction

Stavesacre + Dacarbazine

Dacarbazine brand name: DTIC-Dome.

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 Stavesacre and Dacarbazine 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.

Stavesacre and Dacarbazine

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 Dacarbazine and Stavesacre 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 Stavesacre at all — not against Dacarbazine, 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 Stavesacre and Dacarbazine May Share a Side Effect

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.

Reported for Stavesacre but not commonly for Dacarbazine: itching.

Effects for Dacarbazine come from the ADVERSE REACTIONS section of its FDA label; effects for Stavesacre come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 7,411 voluntary FDA FAERS reports for Dacarbazine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Everything else you take

See Every Supplement That Interacts With Dacarbazine

This page covers Stavesacre only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Dacarbazine page lists 24 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Acerola (moderate), Alpha-lipoic Acid (moderate), Coenzyme Q10 (moderate) and Coffee Charcoal (moderate).

By severity: 1 major · 14 moderate · 9 minor.

From our pharmacist’s overview on the Dacarbazine page

“Activated charcoal carries the only major rating against dacarbazine (DTIC-Dome), and it matters even though this chemotherapy is usually given by IV. Charcoal can trap drugs that recirculate through the gut and lower the amount in your body, and for a medicine fighting melanoma or Hodgkin lymphoma, a weakened dose is a real problem.”

About Stavesacre

What is Stavesacre?

  • Head lice and body lice
  • Skin parasites and scabies
  • Toothache (traditional)
  • Homeopathic remedy for various complaints

Stavesacre is a flowering plant whose seeds were historically used to kill lice and other parasites because they contain toxic alkaloids. It is highly poisonous if swallowed, modern safety data are very limited, and far safer lice treatments now exist, so it is not recommended for internal use.

Delphinium staphisagria · Ranunculaceae · Seeds · Topical preparations, lotions, homeopathic remedies, historically powdered seeds

An interaction check asks whether these two react with each other — it does not ask whether Stavesacre is a good idea for someone in your situation. Here is what our Stavesacre record says about it on its own.

Stavesacre: dosing

There is no established safe or standardized dose for stavesacre, and it is not recommended for internal use because of its toxicity. Because of the poisoning risk, it should not be taken by mouth in any amount.If you come across a topical or homeopathic product containing stavesacre, follow the product label carefully and use it only as directed.

Do Stavesacre and Dacarbazine have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other.
