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 Galphimia Glauca and Chloroquine 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.

Galphimia Glauca and Chloroquine

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 Chloroquine and Galphimia Glauca 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 Chloroquine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Chloroquine is filed under 4 classifications — including cytochrome p450 2d6 (cyp2d6) inhibitors, seizure threshold lowering drugs, oral drugs. Galphimia Glauca has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Chloroquine’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

No Interaction Found — But Data Suggests Galphimia Glauca and Chloroquine 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.

  • Anxiety or restlessness Additional detail

    Galphimia Glauca

    “Orally, Galphimia glauca extract 7-14 mg daily has been associated with sedation and headache. Rarely, restlessness, nervousness, weakness, and other side effects have been reported; but it is unclear if Galphimia glauca was the causal factor.”

From our pharmacist’s overview on the Chloroquine page

“Chloroquine treats and prevents malaria, and that is precisely why its interaction list earns genuine caution, because if a supplement keeps the drug from being fully absorbed, the infection itself can win. Of the 29 supplements and herbs on file, the dominant theme is reduced absorption, and both major-rated entries, activated charcoa…”

About Galphimia Glauca

What is Galphimia Glauca?

Galphimia Glauca
  • Anxiety and stress
  • Insomnia
  • Allergic rhinitis and hay fever
  • Respiratory complaints
  • Traditionally used as an anticonvulsant

Galphimia glauca is a shrub from Mexico and Central America that has been studied mainly for anxiety, with some small clinical trials suggesting possible benefit. Overall the evidence is still limited and its long-term safety is not well established, so talk with your pharmacist or doctor before using it.

Galphimia glauca · Malpighiaceae · Leaves and aerial parts · Capsules, standardized extracts, tinctures, homeopathic preparations, tea

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

Galphimia Glauca: dosing

There is no well-established standard dose of Galphimia glauca. Clinical studies have used standardized extracts, but products on the market vary widely in their strength and how they are made.Because of this, follow the directions on the product label and do not exceed the recommended amount.

About Chloroquine

What Is Chloroquine Used For?

Brand names: Aralen Phosphate, Aralen Phosphate Injection, Aralen HCL, Avloclor, Malarivon, Nivaquine

Chloroquine Phosphate tablets are used to treat uncomplicated malaria caused by susceptible strains of P. falciparum, P. malariae, P. ovale, and P. vivax. They are also used to prevent malaria when traveling to areas where chloroquine-resistant strains are not present.

Chloroquine Phosphate tablets are also approved for extraintestinal amebiasis — an infection with Entamoeba histolytica that has spread outside the intestines, such as to the liver. Important limitations apply: these tablets are not for complicated malaria, not for use in regions where chloroquine resistance is widespread, and they do not prevent malaria relapses caused by P. vivax or P. ovale without an additional medicine.

Taking Galphimia Glauca and Chloroquine Together: Common Questions

Is it safe to take Galphimia Glauca with Chloroquine?
We do not list a known interaction between Galphimia Glauca and Chloroquine. 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 Galphimia Glauca and Chloroquine have any of the same side effects?
Yes — our sources link each of them separately to 3 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.
How was the Galphimia Glauca and Chloroquine combination checked?
Interactions in our licensed database are recorded against drug classes. Chloroquine is filed under 4 classifications, and Galphimia Glauca has documented interactions with 1 drug class — none of Chloroquine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Galphimia Glauca interact with any other medications?
Yes. Galphimia Glauca has 248 documented drug interactions in our database — Chloroquine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Chloroquine interact with any supplements?
Yes. Chloroquine has documented interactions with 29 supplements in our database — Galphimia Glauca is not one of them. The Chloroquine interaction page linked on this page lists every one, ranked by severity.
