HelloPharmacist Scorecard of Forsythia Alcohol Free by Herbal Terra

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 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: forsythia fruit extract (dry form). Forsythia is used in herbal traditions, particularly for respiratory support.

The liquid is made with glycerin and water as inactive ingredients.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Forsythia's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Colds, flu symptoms, sore throat support.
  • We looked for evidence on: Bronchiolitis, Upper respiratory infection, Acute cough, Common cold.
  • The closest evidence on file: Forsythia is rated "Insufficient Reliable Evidence To Rate" for Bronchiolitis (Natural Medicines).

The evidence supporting forsythia for bronchiolitis—the condition most commonly studied for this ingredient—is insufficient. We don't have enough reliable data in our monograph to say whether it works for this purpose or others.

The evidence, ingredient by ingredient Forsythia

How safe is it?

Limited data
Safety Information · database check
Limited information

Little studied safety information is available for these ingredients — that is not the same as being safe.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 0 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.

Forsythia has been used short-term in traditional medicine, but human safety data are limited. The ingredient carries caution for that reason.

There isn't enough safety data to support use during pregnancy or while breastfeeding—talk with your doctor or pharmacist about whether this product is right for you if you're pregnant, trying to conceive, or nursing.

Side effects, ingredient by ingredient Forsythia

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 — Forsythia.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 123 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.

Check before using if you take any blood thinner or antiplatelet drug—aspirin, warfarin, clopidogrel (Plavix), enoxaparin (Lovenox), heparin, and similar drugs (Moderate severity). Also double-check if you're on azithromycin (Zithromax) or other macrolide antibiotics (Minor severity).

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is limited.

If you're not on blood thinners, antiplatelet drugs, or azithromycin, forsythia is generally well tolerated in the short term, though long-term human data are sparse. If you take any of those medications, check with us first.

And if you're pregnant or breastfeeding, there isn't enough safety information to guide a decision—your pharmacist or doctor can help you weigh your options.

Forsythia Fruit Extract, Dry2 drug types · 123 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking forsythia with anticoagulant or antiplatelet drugs might increase the risk of bleeding due to decreased platelet aggregation. Forsythia might reduce platelet aggregation by inhibiting platelet activating factor. Some of these drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

Likelihood Unlikely Evidence D
Azithromycin (Zithromax)

Theoretically, taking forsythia with azithromycin might increase the risk of adverse effects. Animal research in rats shows that taking a single dose of forsythia with azithromycin decreases the clearance and increases the area under the curve of both forsythiaside, a constituent of forsythia, and azithromycin. The mechanism of this interaction is not well understood.
