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: Jamaica Dogwood Bark Extract, a liquid made from the bark of the Jamaica Dogwood plant. The extract is suspended in certified organic cane alcohol and distilled water.

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: nervous system support and minor pain relief.
  • We looked for evidence on: insomnia, anxiety, nerve pain, muscle tension.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

We hold no effectiveness ratings in our data for Jamaica Dogwood Bark Extract. The evidence for what this ingredient is used for isn't established in the information we have on file.

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.

Jamaica Dogwood carries important safety concerns. The safety notes flag that it can be toxic at higher doses and has very limited safety data in humans—so we don't know much about its long-term use or its effects at different amounts.

Because of traditional use patterns and lack of human safety data, it's advised against during pregnancy and while breastfeeding. If you're pregnant, planning to become pregnant, or nursing, talk with your pharmacist or doctor before considering this product.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Jamaican Dogwood.
  • The most serious interaction on file is rated Moderate.
  • For scale: 248 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 any sedatives, sleep aids, anti-anxiety medications, or opioids you're taking—Jamaica Dogwood may increase their sedative effects. Because 248 medications fall into this category, use the interaction checker on this page with your exact drug names and doses.

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.

Jamaica Dogwood is a single-ingredient herbal extract that interacts with a large number of sedating medications. If you take any central nervous system depressants—sleep aids, anti-anxiety drugs, sedatives, or opioids—check your specific medications before starting.

Pregnant people and those breastfeeding should avoid it. Run this by your pharmacist before you use it.

Jamaica Dogwood by Herb Pharm: Common Questions

Does Jamaica Dogwood by Herb Pharm interact with any medications?
Yes. Based on its ingredients, Jamaica 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?
Jamaica 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 Jamaica Dogwood if I'm pregnant or breastfeeding?
No. Jamaica Dogwood is rated likely unsafe in pregnancy because it's traditionally been linked to effects on the uterus and lacks safety data. It's also rated likely unsafe while breastfeeding. If you're pregnant, planning pregnancy, or nursing, talk with your doctor or pharmacist before taking any herbal products.
What are the side effects of Jamaica Dogwood?
We don't have adverse effects data on file for this ingredient. What we do know is that it can be toxic in higher doses and has limited safety information in humans—so the full picture of what side effects might occur isn't well established.
Is this safe to take long-term?
There's limited safety data in humans for Jamaica Dogwood, and it can be toxic at higher doses. Long-term use safety hasn't been well studied, so talk with your pharmacist about how long you plan to take it and whether that's appropriate for you.
Why does this product have alcohol in it?
This is a liquid herbal extract, and certified organic cane alcohol is used as the solvent to pull the active compounds from the Jamaica Dogwood bark. It's a common carrier for herbal tinctures.
