HelloPharmacist Scorecard of Cang Zhu 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.

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 liquid contains one active ingredient: atractylodes root extract (in dry form). Atractylodes is a plant used traditionally in herbal medicine, though what it actually does in the body isn't well established by research.

The product also contains alcohol, water, and glycerin as inactive ingredients that help deliver and preserve the extract.

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 Atractylodes product and its label doesn't state a use — see Atractylodes'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.

The evidence for what atractylodes does isn't established in our data. It's been studied traditionally for anorexia nervosa, cancer cachexia (wasting), lung cancer, common cold, and diarrhea, but in each case the reliable evidence is insufficient to rate whether it works.

If you're considering this for a specific condition, talk with your pharmacist or doctor about whether there's solid evidence behind it.

The evidence, ingredient by ingredient Atractylodes

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.

Human safety data for atractylodes are limited, so use this product cautiously and under guidance from a healthcare provider. The most common side effects reported orally are allergic reaction, dry mouth, and nausea.

The safety data advises against use during pregnancy, and safety while breastfeeding is unknown, so it's best avoided if you're pregnant or nursing. A thorough safety evaluation hasn't been completed, so unexpected effects are possible.

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 — Atractylodes.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 802 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 your medications against this product if you take blood thinners or antiplatelet drugs (like warfarin, clopidogrel, or aspirin), aromatase inhibitors for cancer, or any medication your liver breaks down — especially if it's a narrow-window drug where even small changes matter.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Cang Zhu is a traditional herbal product with limited human safety data and theoretical interactions with blood thinners and several other medication types — none proven in people yet, but worth checking. If you take any prescription medications, especially blood thinners or cancer drugs, run them through our checker before starting.

Talk with your pharmacist about whether the evidence supports what you're hoping it will do.
