HelloPharmacist Scorecard of Camphor Tree by Herbal Terra

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.

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.

Camphor Tree contains one active ingredient: a dried resin liquid extract from the camphor tree (Cinnamomum camphora). It also includes menstruum as an inactive ingredient — a solvent used to extract and preserve the herb.

Camphor has a long history in topical and inhalation products for cough, pain, and itching. This is a liquid extract, so it's meant to be used as directed — not swallowed straight from the bottle.

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).

The evidence supports camphor for three main uses. It's likely effective for cough, for acute pain relief, and for itching.

These ratings come from clinical data in our monograph. Keep in mind that this is a liquid extract, so how you use it — topically, inhaled, or as directed — matters for whether you'll see the benefit.

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 part: camphor is unsafe if you swallow it. Oral ingestion can cause serious toxicity, including stomach symptoms, eye problems, and neurological effects — especially at high doses.

If you ingest more than small amounts (over 50 mg/kg), you risk serious harm including heart rhythm problems and breathing trouble. For topical use in limited amounts, camphor is generally well tolerated, though skin irritation or dermatitis can happen.

If you inhale it, nose and sinus irritation is common. Avoid putting it on your chest or breast, and talk with your doctor before you use it.

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

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 you start, double-check your medications against any that are hard on the liver (hepatotoxic drugs). This product has a documented Moderate-severity interaction with that drug class, and there's a chance of liver enzyme changes or, rarely, liver damage.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Camphor works well for cough, acute pain, and itching when used topically or inhaled in small amounts — but it's dangerous if swallowed. If you take any medication that affects your liver, check with your pharmacist or doctor before adding this product.

Pregnant or breastfeeding? This one is not for you.

Talk it over with your own doctor or pharmacist about whether it fits your situation.
