The bottom line No known interaction

We found no known interaction between Yerba Mansa and Scopolamine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist.

Yerba Mansa and Scopolamine

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 Scopolamine and Yerba Mansa 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 Scopolamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Scopolamine is filed under 4 classifications — including anticholinergic drugs, topical drugs, oral drugs. Yerba Mansa has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Scopolamine’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 Scopolamine’s Own FDA Label Lists

This is not an interaction — none of it involves Yerba Mansa. These are the most notable effects listed in the ADVERSE REACTIONS section of Scopolamine’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 6 of them are worth acting on rather than waiting out — marked below.

  • Dependence or withdrawal symptoms Worth acting on
  • Pain or burning when passing urine Worth acting on
  • Memory problems Worth acting on
  • Hallucinations Worth acting on
  • Confusion Worth acting on
  • Seizures Worth acting on
  • Trouble concentrating
  • Dry eyes
  • Blurred vision
  • Sore throat

Showing the 10 most notable of 17 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Scopolamine. Read the label on DailyMed › Where a percentage is shown, it is the share of 6,682 voluntary FDA FAERS reports for Scopolamine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Yerba Mansa’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Yerba Mansa side to compare — that is a limit of the record, not a statement that Yerba Mansa has no side effects.

See Every Supplement That Interacts With Scopolamine

This page covers Yerba Mansa only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Scopolamine page lists 51 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), Henbane (major), Scopolia (major) and Angel's Trumpet (moderate).

By severity: 4 major · 34 moderate · 13 minor.

From our pharmacist’s overview on the Scopolamine page

“Scopolamine, the motion sickness medicine most people wear as the Transderm Scop patch, sits on the serious end of supplement interactions, so learn the four major entries first. Most of the 51 ingredients here, 30 of them, pile the same anticholinergic side effects on top of the drug: dry mouth, blurred vision, constipation, confusion.”

About Yerba Mansa

What is Yerba Mansa?

Yerba Mansa
  • Sore throat and respiratory congestion
  • Skin irritation and wounds
  • Mouth and gum inflammation
  • Urinary and digestive complaints
  • Antimicrobial support

Yerba mansa is a traditional Southwestern and Mexican medicinal plant used for sore throats, skin problems, and infections. Modern scientific evidence in humans is very limited, so its effectiveness is largely unproven. If you want to try it, talk to a pharmacist or doctor first, and avoid it during pregnancy and breastfeeding.

Anemopsis californica · Saururaceae · Root (rhizome) and leaves · Dried root, tea, tincture, capsules, powder, topical washes and salves

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

Yerba Mansa: dosing

There is no established, standardized dose for yerba mansa. Traditional use varied widely depending on whether it was prepared as a tea, tincture, or topical wash, and the strength of commercial products differs from brand to brand.If you choose to use a product, follow the directions on the label and do not exceed the suggested amount.
