Drug & supplement interaction

Griffonia Simplicifolia + Infliximab

Infliximab brand name: Remicade.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Griffonia Simplicifolia and Infliximab 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.

Griffonia Simplicifolia and Infliximab

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 Infliximab and Griffonia Simplicifolia 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.

What to actually watch for

No Interaction Found — But Data Suggests Griffonia Simplicifolia and Infliximab 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.

  • Stomach pain Additional detail

Overlapping uses

What Infliximab Is Prescribed For, and What Griffonia Simplicifolia Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Infliximab is a prescription medicine with approved uses on its FDA label. Griffonia Simplicifolia is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Infliximab is prescribed for: Infliximab injection is used to treat several serious inflammatory conditions. It treats moderately to severely active Crohn's disease (including fistulizing disease) and ulcerative colitis in adults, and in children ages 6 and older. It also treats moderately to severely active rheumatoid arthritis (in combination with methotrexate), ankylosing spondylitis (a type of spinal arthritis), psoriatic arthritis, and chronic severe plaque psoriasis in adults. Infliximab is intended for patients whose disease has not responded well enough to conventional therapies.

It is available under the brand names INFLECTRA, Remicade, and Renflexis, all given by intravenous (IV) infusion.

Griffonia Simplicifolia has been studied for:

  • Diarrhea studied, not established Griffonia Simplicifolia has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Griffonia Simplicifolia for diarrhea

    Although there has been interest in using oral Griffonia simplicifolia seed for diarrhea, there is insufficient reliable information about the clinical effects of Griffonia simplicifolia for this purpose.

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 Infliximab on your own; if you are taking Griffonia Simplicifolia for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Griffonia Simplicifolia

What is Griffonia Simplicifolia?

Griffonia Simplicifolia
  • Low mood
  • Sleep problems
  • Anxiety
  • Appetite control
  • Headaches

Griffonia simplicifolia is a West African shrub whose seeds are a natural source of 5-HTP, a building block of the brain chemical serotonin. Some people use it for mood, sleep, and appetite, but high-quality human evidence is limited, and it should not replace prescribed treatment. Talk with your pharmacist or doctor before using it, especially if you take medicines that affect serotonin.

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

Griffonia Simplicifolia: dosing

There is no official, well-established dose for Griffonia simplicifolia. Products are usually standardized to a certain amount of 5-HTP, and the strength can differ a lot from one brand to another.The safest approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Griffonia Simplicifolia and Infliximab Together: Common Questions

Is it safe to take Griffonia Simplicifolia with Infliximab?
We do not list a known interaction between Griffonia Simplicifolia and Infliximab. 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 Griffonia Simplicifolia and Infliximab have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
Are Griffonia Simplicifolia and Infliximab used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Griffonia Simplicifolia in each. That is a conversation for your prescriber, especially if Infliximab is being adjusted to a target.
Does Griffonia Simplicifolia interact with any other medications?
Yes. Griffonia Simplicifolia has 317 documented drug interactions in our database — Infliximab is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
