The bottom line No known interaction

We found no known interaction between European Buckthorn and Amphetamine 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.

European Buckthorn and Amphetamine

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 Amphetamine and European Buckthorn 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.

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.

How we checked

Why No Interaction Is Listed for Amphetamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Amphetamine is filed under 6 classifications — including monoamine oxidase inhibitors (maois), amphetamines, stimulant drugs. European Buckthorn has documented interactions with 4 drug classes — the most serious being digoxin (lanoxin) (major), diuretic drugs (moderate) and stimulant laxatives (moderate) — and none of Amphetamine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What European Buckthorn Itself Has Been Linked To

This is not an interaction — nothing below involves Amphetamine. It is the side-effect record for European Buckthorn on its own, from the licensed Natural Medicines monograph. If something new turns up after you add European Buckthorn, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Muscle weakness / Low potassium Worth acting on Additional detail

    “Orally, European buckthorn seems to be well tolerated, short term. It can cause abdominal pain, cramps, or watery diarrhea (12). Chronic use or abuse of the berry can lead to potassium depletion, albuminuria, and hematuria. Potassium depletion can lead to disturbed heart function and muscle weakness (2).”

  • Stomach pain / Diarrhea Additional detail

    “Orally, European buckthorn can cause abdominal pain, cramps, or watery diarrhea (12). Chronic use can cause pseudomelanosis coli (pigment spots in intestinal mucosa) which is harmless, usually reverses with discontinuation (2), and is not associated with an increased risk of developing colorectal adenoma or carcinoma.”

We haven’t matched Amphetamine to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Amphetamine.

About European Buckthorn

What is European Buckthorn?

  • Constipation
  • Occasional laxative use
  • Digestive complaints
  • Traditional 'detox' remedies

European Buckthorn is a shrub whose bark and berries contain compounds that act as a strong, irritant-type laxative. Because it can cause cramping, fluid and electrolyte loss, and the berries can be toxic if eaten raw, it is rarely recommended today and safer constipation options are usually preferred. Talk to a pharmacist or doctor before using it.

Rhamnus cathartica · Rhamnaceae · Bark and berries (fruit) · Dried bark, tinctures, teas, and liquid extracts (rarely sold as a modern standardized supplement)

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

European Buckthorn: dosing

There is no well-established, standardized dose for European Buckthorn supplements, and the strength of homemade preparations can vary widely. This is one reason it is hard to use safely.If a product is used at all, it should be a properly labeled commercial preparation, taken exactly as directed and only for short-term use.
