HelloPharmacist Scorecard of Aspen Flower Essence by Flower Essence Services

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 16, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.

Aspen Flower Essence contains one active ingredient: an infusion of Populus tremula (aspen). The product is prepared at a 1:6000 dilution and delivered in a liquid form that includes water and brandy as inactive ingredients.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Aspen product and its label doesn't state a use — see Aspen's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

We have no documented effectiveness ratings in our data for aspen. The evidence supporting its use has not been established in the information we hold.

The evidence, ingredient by ingredient Aspen

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Aspen contains aspirin-like compounds called salicylates and should be used carefully because it may cause similar side effects to aspirin. The safety data advises against use during pregnancy because of its aspirin-like activity and the lack of safety information.

Avoid it while breastfeeding as well — salicylates can pass into breast milk and there isn't enough data to confirm safety. Adverse effects related to aspen are not well documented in the literature.

However, because it contains salicin (a plant salicylate), it could theoretically cause side effects similar to aspirin if taken by mouth. Topically, aspen has been linked to allergic skin reactions, including cases of contact dermatitis in people handling aspen leaves and bark.

Side effects, ingredient by ingredient Aspen

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Aspen.
  • The most serious interaction on file is rated Moderate.
  • For scale: 39 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Aspen Flower Essence, check with your doctor or pharmacist if you take aspirin, choline magnesium trisalicylate (Trilisate), or salsalate (Disalcid) — these are Moderate severity interactions due to aspen's salicylate content, which could theoretically add to theirs. Review your full medication list on this page's checker to see if any other drugs are flagged.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Aspen Flower Essence is a single-ingredient liquid supplement containing aspen infusion. Because it carries aspirin-like compounds, it's not suitable during pregnancy or breastfeeding, and it should not be combined with aspirin or similar salicylate-containing medications without your doctor or pharmacist's clearance.

If you take any prescription or over-the-counter drugs, talk with your healthcare provider before starting this product.

Aspen Flower Essence by Flower Essence Services: Common Questions

Does Aspen Flower Essence by Flower Essence Services interact with any medications?
Yes. Based on its ingredients, Aspen Flower Essence has a known interaction with 39 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Aspen Flower Essence contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is aspen safe to use while I'm pregnant or breastfeeding?
No. The safety data advises against use during pregnancy because of aspen's aspirin-like activity and lack of safety information. Avoid it while breastfeeding too — salicylates from aspen can pass into breast milk. Talk with your doctor or pharmacist about whether this product is right for you.
What is salicin, and why should I care?
Salicin is a plant compound in aspen that's chemically similar to aspirin. Because of that, aspen can potentially add to the effects of aspirin and other salicylate-containing medications, which is why it matters if you take those drugs.
Can aspen cause skin reactions?
Yes, topically (on the skin). Cases of allergic contact dermatitis have been reported in people who handled aspen leaves and bark directly. Oral use side effects aren't well documented, but aspen could theoretically cause aspirin-like effects if taken by mouth.
What is this product actually used for?
The effectiveness ratings we hold do not establish evidence supporting its use. You may want to ask your doctor or pharmacist about the intended purpose and whether the evidence supports it.
Can I take aspen with my blood thinner or NSAID?
You'll need to check with your doctor or pharmacist first. Aspen contains salicylates, which can interact with aspirin and aspirin-like drugs. Use the medication checker on this page to see if any of your medications are flagged, and bring those results to your healthcare provider.
