Calea Zacatechichi and Atorvastatin

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 Atorvastatin 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.

Calea Zacatechichi safety at a glance

Calea Zacatechichi overall Use caution It has a long folk-use history but little modern safety data, and it can cause nausea and vomiting.
Pregnancy Avoid There is no reliable safety data, so it is best avoided during pregnancy.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Atorvastatin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Atorvastatin is filed under 7 classifications — including hmg-coa reductase inhibitors ("statins"), organic anion-transporting polypeptide substrates (oatp), glucuronidated drugs. Calea Zacatechichi has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (minor) and cns depressants (minor) — and none of Atorvastatin’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.

See Every Supplement That Interacts With Atorvastatin

This page covers Calea Zacatechichi only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Atorvastatin page lists 181 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Apple (major), Beer (major), Grapefruit (major) and Green Tea (major).

By severity: 9 major · 136 moderate · 36 minor.

From our pharmacist’s overview on the Atorvastatin page

“Grapefruit is the entry to understand first. Atorvastatin (Atorvaliq) is cleared by an enzyme called CYP3A4, and grapefruit blocks that enzyme, letting statin levels climb along with the risk of side effects like muscle pain.”

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.
