HelloPharmacist Scorecard of Forsythia Alcohol Free by Hawaii Pharm

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

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 in a concentrated, dry form. Forsythia is a plant used in traditional herbal practice, and this liquid preparation includes glycerin and water as inactive ingredients to dissolve and preserve the extract.

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 Forsythia product and its label doesn't state a use — see Forsythia'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.

The data we hold shows insufficient reliable evidence to rate forsythia for bronchiolitis or other conditions. That doesn't mean it doesn't work—it means the clinical evidence isn't yet robust enough to make a confidence claim about its use.

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 is generally used short-term in traditional medicine, but human safety data are limited. We don't have enough data to know whether this product is safe during pregnancy or while breastfeeding, so the safety data advises against use in both cases.

There are no adverse effects reported in the data we hold, but the limited human study means rare or long-term effects may not yet be known.

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.

Double-check this product with your doctor or pharmacist if you take any blood thinners or antiplatelet drugs (like aspirin or clopidogrel), which carry a moderate risk of increased bleeding. Also confirm its safety if you take azithromycin (Zithromax) or any other prescription medications, since the interaction data span many drugs.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is limited.

Forsythia Alcohol Free is worth considering if you're interested in traditional herbal support and don't take blood thinners or azithromycin. If you do take either, check with your doctor or pharmacist before starting.

Because human safety data are limited, talk it over with your own healthcare provider before taking it, especially if you're pregnant, breastfeeding, or taking any regular medications.

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.

Forsythia Alcohol Free by Hawaii Pharm: Common Questions

Does Forsythia Alcohol Free by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Forsythia Alcohol Free has a known interaction with 123 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Forsythia Alcohol Free 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 Forsythia Alcohol Free safe to take while pregnant?
No, the safety data advises against use during pregnancy. There isn't enough information to know whether it's safe for an unborn baby. Talk with your doctor or pharmacist before taking it if you are or might become pregnant.
Can I take this while breastfeeding?
The safety data advises against it while breastfeeding. We don't have enough information to know if forsythia passes into breast milk or could affect a nursing baby. Check with your doctor or pharmacist for personalized advice.
Does this product actually work for bronchiolitis?
The evidence we hold is not strong enough to make a reliable claim about how well it works for bronchiolitis or any other condition. If you're considering it for a specific health issue, talk with your doctor about whether it's right for you.
Why does this have 'alcohol free' in the name?
Many herbal extracts are made with alcohol as a preservative. This version uses glycerin and water instead, making it alcohol-free for those who need or prefer to avoid alcohol.
What is forsythia fruit extract used for?
Forsythia is a plant used in traditional herbal medicine, especially for respiratory support. Our data don't show strong clinical evidence for any specific condition, but it's been used traditionally for short-term support.
