HelloPharmacist Scorecard of Cang Zhu 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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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.

Cang Zhu contains one active ingredient: atractylodes root extract (the dried form). Atractylodes is a traditional herb used in Asian medicine.

The liquid also contains alcohol, water, and glycerin as inactive ingredients.

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 we hold doesn't establish that atractylodes works for any condition. The data rates it as having insufficient reliable evidence for anorexia nervosa, cachexia (wasting), lung cancer, common cold, and diarrhea — meaning human studies either don't exist, are too small or poorly designed, or conflict.

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 it cautiously and ideally under guidance. The most common side effects reported with oral use are allergic reaction, dry mouth, and nausea; an isolated constituent can also cause bad taste.

Because safety data in pregnancy are not reliable enough, atractylodes is best avoided during pregnancy. Safety while breastfeeding is unknown, so avoid it during that time too.

Side effects, ingredient by ingredient Atractylodes

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 — 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.

Before taking Cang Zhu, check whether you're on blood thinners or antiplatelet drugs (moderate risk), aromatase inhibitors or hexobarbital (moderate risk), or drugs processed through CYP1A2 or CYP3A4 liver pathways (minor risk). Your pharmacist can search your exact medications using the tool on this page.

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.

Atractylis lancea Root Extract, Dry5 drug types · 801 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, atractylodes might increase the risk of bleeding when used concomitantly with anticoagulant and antiplatelet drugs.
Laboratory research suggests that atractylenolides II and III, constituents of atractylodes, reduce platelet activation. So far, this has not been shown in humans.

Likelihood Possible Evidence D
Aromatase Inhibitors

Theoretically, atractylodes may have an additive effect when used with other aromatase inhibitors.
Laboratory research suggests that atractylodes and its constituents exhibit aromatase inhibitor effects.

Likelihood Possible Evidence D
Hexobarbital

Theoretically, taking atractylodes may prolong the therapeutic and adverse effects of hexobarbital.
In animals, atractylodes has been shown to prolong the effects of hexobarbital. These effects have not been shown in humans.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, atractylodes might decrease the levels of CYP1A2 substrates.
In animals, atractylodes administered at high doses has been shown to induce CYP1A2 activity. This effect has not been shown in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, atractylodes might increase the levels of CYP3A4 substrates.
In animals, atractylodes administered at high doses has been shown to inhibit CYP3A1 activity, which is a homolog to the human CYP3A4 enzyme. This effect has not been shown in humans.

Cang Zhu by Hawaii Pharm: Common Questions

Does Cang Zhu by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Cang Zhu has a known interaction with 801 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cang Zhu 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.
What is Cang Zhu used for?
Cang Zhu contains atractylodes, a traditional herb. However, the evidence we hold doesn't establish that it works for anorexia nervosa, cachexia, lung cancer, common cold, diarrhea, or other conditions — the data on human effectiveness simply isn't there yet.
Can I take this while pregnant or breastfeeding?
No. Atractylodes safety data in pregnancy aren't reliable enough, so it's best avoided. Safety while breastfeeding is also unknown, so avoid it then too. Talk with your doctor if you have questions.
What are the side effects?
The most common ones reported with oral use are allergic reaction, dry mouth, and nausea. An isolated component can also cause bad taste. Human safety data are limited, though, so a thorough safety evaluation hasn't been done.
Does atractylodes interact with blood thinners like warfarin?
Yes — it's a moderate-severity interaction. Atractylodes may theoretically increase bleeding risk when used with blood thinners or antiplatelet drugs like aspirin. This hasn't been proven in humans, but animal research suggests it affects how platelets work. Check with your pharmacist before starting.
Why is there an alcohol content in a liquid extract?
The product uses alcohol, water, and glycerin as inactive ingredients — they're the base that carries and preserves the atractylodes extract in liquid form. If you need to avoid alcohol, check the label for the exact percentage or ask your pharmacist.
