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 liquid contains one active ingredient: Jamaican Dogwood Bark Extract, Dry. It's prepared as a concentrated extract in a base of alcohol, water, and glycerin.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Sleep support and relaxation.
  • We looked for evidence on: Insomnia, Sleep quality, Nervous tension.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The data we hold does not include effectiveness ratings for Jamaican Dogwood. We can't tell you from our records how well it works or for what conditions the evidence supports it.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Jamaican Dogwood comes with significant cautions. It can be toxic in higher doses and has limited safety data in humans, so dosing should be careful and conservative.

It's not safe in pregnancy — there's a traditional link to uterine effects and no solid safety data — and it's not safe while breastfeeding either, because we don't know if it passes into breast milk or what effects it might have on an infant.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

This is a product you'll want to discuss with your pharmacist or doctor before starting, especially if you take any sedating medications. The interaction potential is broad, safety data is thin, and dosing matters.

If you're pregnant or breastfeeding, this product should be avoided.

Jamaican Dogwood by Hawaii Pharm: Common Questions

Does Jamaican Dogwood by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Jamaican Dogwood has a known interaction with 248 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Jamaican Dogwood 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.
Can I take this while pregnant?
No. Jamaican Dogwood is rated likely unsafe in pregnancy because it's been traditionally linked to effects on the uterus and there's not enough safety data to know it's okay. Skip it and talk with your OB or midwife about alternatives.
Is it safe to breastfeed while taking Jamaican Dogwood?
No. It's rated likely unsafe while breastfeeding because we don't have enough data to know if it passes into breast milk or what it might do to your baby. Avoid it and ask your pharmacist about safer options.
What's in this liquid besides the active ingredient?
The liquid base contains alcohol, water, and glycerin. Those are excipients — they help deliver the extract. If you need to avoid alcohol, check the label for exact concentration before using it.
Why is there a warning about toxicity?
Jamaican Dogwood can be toxic at higher doses and doesn't have much safety testing in people. That's why sticking to the recommended dose and checking with your pharmacist beforehand is important.
Can I take this with my sleep medication?
You need to check with your pharmacist first. Jamaican Dogwood may boost the sedative effects of sleep aids and similar CNS depressants, which could make you too drowsy or uncoordinated. Use the medication checker on this page or ask us before you combine them.
