No Known Interaction

The bottom line No known interaction

We found no known interaction between Calea Zacatechichi and Salsalate 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.

Calea Zacatechichi and Salsalate

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 Salsalate and Calea Zacatechichi 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 Salsalate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Salsalate is filed under 6 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates. Calea Zacatechichi has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (minor) and cns depressants (minor) — and none of Salsalate’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.

No Interaction Found — But Data Suggests Calea Zacatechichi and Salsalate 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.

    Salsalate

    Listed in the ADVERSE REACTIONS section of the FDA label for Salsalate, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Calea Zacatechichi but not commonly for Salsalate: drowsiness and vomiting.

Effects for Salsalate come from the ADVERSE REACTIONS section of its FDA label; effects for Calea Zacatechichi come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 934 voluntary FDA FAERS reports for Salsalate 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 Salsalate

This page covers Calea Zacatechichi only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Salsalate page lists 37 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Beer (major), Siberian Cocklebur (major) and Wine (major).

By severity: 5 major · 20 moderate · 12 minor.

From our pharmacist’s overview on the Salsalate page

“Beer and wine top my worry list for anyone taking salsalate (Disalcid), an aspirin-like salicylate used for arthritis pain, since alcohol alongside it raises the risk of stomach and intestinal bleeding. Those drinks account for two of the five major-rated interactions among the 37 ingredients on file, and this list deserves real caution.”

About Calea Zacatechichi

What is Calea Zacatechichi?

  • Promoting vivid or lucid dreams
  • Sleep and relaxation
  • Digestive upset
  • Fever
  • Traditional ritual use

Calea zacatechichi, often called 'dream herb,' is a Mexican plant traditionally used to encourage vivid dreams and to treat digestive complaints and fever. Human research is very limited, so its benefits are not well proven, and its safety has not been carefully studied. It tastes very bitter, can cause nausea, and should be avoided during pregnancy and breastfeeding.

Calea ternifolia · Asteraceae · Leaves and flowering tops (dried) · Dried leaf tea, capsules, tincture/liquid extract, and smoked dried leaf

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

Do Calea Zacatechichi and Salsalate 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.

Salsalate is filed under 6 classifications, and Calea Zacatechichi has documented interactions with 2 drug classes — none of Salsalate'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.
