HelloPharmacist Scorecard of Eastern Red Cedar Non-Alcohol 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: Eastern Red Cedar Chip Extract, a dried extract made from cedar wood chips. The rest is glycerin and water, which help preserve and deliver the extract.

Eastern red cedar has been used traditionally for aroma and topical purposes, though human safety research is still limited.

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 Eastern Red Cedar product and its label doesn't state a use — see Eastern Red Cedar'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 don't have effectiveness data on file for Eastern Red Cedar in our monograph, so we can't tell you what it's meant to do or how well it works for any particular condition.

The evidence, ingredient by ingredient Eastern Red Cedar

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.

This is where you need to be careful. The safety notes flag that while topical cedar oil is generally well tolerated, swallowing the essential oil carries real risks — overdose can cause stomach burning, vomiting, convulsions, and in severe cases, coma or death.

The product label says non-alcohol, but it's still an extract meant for small doses. Eastern red cedar is not safe in pregnancy because cedar oils can irritate tissues and safety hasn't been established.

Breastfeeding is also advised against — there isn't enough data to know it's safe.

Side effects, ingredient by ingredient Eastern Red Cedar

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Eastern Red Cedar.
  • The most serious interaction on file is rated Minor.
  • For scale: 49 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.

Barbiturates (sedative drugs) are the main one to flag. Cedar extract can speed up how your body clears these drugs, potentially reducing their effect.

Check any sedatives or sleep aids you're on before you start.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Only minor medication interactions are documented, and safety information is well characterized.

If you're considering this for its traditional uses, talk with your pharmacist first about how to use it safely and whether it's right for you. Pregnant or breastfeeding?

Skip this one. If you take barbiturates or sedatives, check with us before starting — we need to make sure it won't interfere with how your medication works.

Barbiturates

In mice and rats given hexobarbital or pentobarbital, sleep time is reduced and metabolism of the drug is increased when they inhale essential oil vapor from Eastern red cedar wood chips in their bedding. Cedrol and cedrene in the essential oil are reported to induce liver microsomal enzymes. Theoretically, inhaling Eastern red cedar wood fragrance might reduce the efficacy of hexobarbital or pentobarbital in humans.
