The bottom line No known interaction

We found no known interaction between Ash 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. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Ash 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 Ash 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.

Ash safety at a glance

Ash overall Use caution Likely fine in food amounts, but medicinal use lacks strong safety data.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid No reliable safety data, so avoid while breastfeeding.

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

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. Ash has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and antihypertensive drugs (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.

Keep it in perspective

What to actually watch for

What Scopolamine’s Own FDA Label Lists

This is not an interaction — none of it involves Ash. 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. Ash’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Ash side to compare — that is a limit of the record, not a statement that Ash has no side effects.

Everything else you take

See Every Supplement That Interacts With Scopolamine

This page covers Ash 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 Ash

What is Ash?

Ash
  • Joint pain and arthritis
  • Fever
  • Constipation
  • Fluid retention (diuretic)
  • Bladder and urinary complaints
  • Weight management and blood sugar

Ash (Fraxinus excelsior and related species) is a tree whose leaves, bark, and seeds have a long history in folk medicine for arthritis, fever, and fluid retention. Solid human evidence is limited for nearly all of these uses, so it should not replace proven treatments. Talk with your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

Fraxinus excelsior · Oleaceae · Leaves, bark, and seeds · Tea, dried leaf, capsules, tinctures, extracts

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

Ash: dosing

There is no well-established standard dose for ash. Amounts vary widely between teas, tinctures, capsules, and extracts.If you choose to use an ash product, follow the directions on the label and do not exceed them.
