Drug & supplement interaction

Lesser Celandine + Methamphetamine

Methamphetamine brand name: Desoxyn.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Lesser Celandine and Methamphetamine 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.

Interaction report

Lesser Celandine and Methamphetamine

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 Methamphetamine and Lesser Celandine 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 Lesser Celandine at all — not against Methamphetamine, 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 Lesser Celandine and Methamphetamine 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.

  • Diarrhea Additional detail

    “Orally, lesser celandine may cause severe gastrointestinal irritation, colic, diarrhea, and irritation of the urinary tract (18). One report associates the use of lesser celandine with a case of recurrent, acute hepatitis.

About Lesser Celandine

What is Lesser Celandine?

  • Hemorrhoids
  • Skin sores and itching
  • Scurvy (historically, as a spring green)
  • Minor wounds

Lesser Celandine is a small spring wildflower with a long folk reputation for treating hemorrhoids (one of its old names is 'pilewort'). There is very little modern scientific evidence that it works for any condition, and the fresh plant is irritating and can be toxic if used improperly. It is best avoided as an internal supplement, and you should talk to a pharmacist or doctor before using it.

Ficaria verna · Ranunculaceae · Aerial parts (leaves and flowers) and root · Traditional ointments, tinctures, and dried herb preparations

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

Lesser Celandine: dosing

There is no established or standardized dose for Lesser Celandine. It is not a common commercial supplement, and reliable dosing information from clinical research does not exist.If you are considering a traditional product that contains it, follow the product label exactly and do not use the fresh plant on your own.

Taking Lesser Celandine and Methamphetamine Together: Common Questions

Is it safe to take Lesser Celandine with Methamphetamine?
We do not list a known interaction between Lesser Celandine and Methamphetamine. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Lesser Celandine and Methamphetamine 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. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Methamphetamine interact with any supplements?
Yes. Methamphetamine has documented interactions with 126 supplements in our database — Lesser Celandine is not one of them. The Methamphetamine interaction page linked on this page lists every one, ranked by severity.
