HelloPharmacist Scorecard of Camphor Tree 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: Camphor Tree Resin Extract, Dry. It's made from the resin of the camphor tree and comes as a liquid.

The formula also includes alcohol, water, and glycerin as inactive ingredients.

Does it work?

Strong evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Camphor's overall clinical evidence instead.

Strong

Strong clinical evidence supports Camphor for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Cough — rated "Likely Effective" (Natural Medicines).
  • On file: Pain (acute) — rated "Likely Effective" (Natural Medicines).
  • On file: Pruritus — rated "Likely Effective" (Natural Medicines).

Camphor is likely effective for cough, acute pain, and itching (pruritus). The evidence supports its use for these purposes, though it's best used topically or by inhalation rather than swallowed—oral camphor carries serious safety risks.

The evidence, ingredient by ingredient Camphor

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.

Here's the critical point: camphor is unsafe if swallowed or overused, and can cause serious toxicity if taken by mouth. Topical and inhaled use in regulated amounts is generally well tolerated, but you should avoid applying it to your chest or breast area and talk with your doctor before use.

When used topically, the most common side effect is skin irritation or dermatitis. Inhalation can irritate your nose and sinuses.

Camphor is unsafe in pregnancy and lactation—do not use if you're pregnant or breastfeeding.

Side effects, ingredient by ingredient Camphor

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 — Camphor.
  • The most serious interaction on file is rated Moderate.
  • For scale: 371 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.

Before using this product, check with your doctor or pharmacist if you take any hepatotoxic drugs—medications that can stress your liver. These interactions are moderate in severity, meaning the risk of liver damage could increase if you combine them with camphor.
