HelloPharmacist Scorecard of Calamus Root Powder by Bixa Botanical

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: Acorus calamus powder, a traditional herbal material. There are no inactive ingredients listed.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Calamus's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: supports stomach spasm relaxation.
  • We looked for evidence on: Dyspepsia, Flatulence, Gastritis, Colic, abdominal cramping, intestinal spasm.
  • The closest evidence on file: Calamus is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia (Natural Medicines).
  • Also on file: Calamus is rated "Insufficient Reliable Evidence To Rate" for Flatulence, Colic, Gastritis.

The evidence for calamus in conditions like bronchitis, asthma, and anorexia nervosa is insufficient—we don't have reliable data to say whether it works for these uses. The facts we have don't establish effectiveness for any condition.

The evidence, ingredient by ingredient Calamus

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.

Calamus carries serious safety concerns. Some forms contain beta-asarone, a compound the FDA has banned from food because it's a possible cancer risk, and calamus itself is considered likely unsafe because of cancer risk.

Common side effects from taking it by mouth include nausea and vomiting. Rare but serious effects—intestinal paralysis and accelerated heartbeat (tachycardia)—have been reported.

Because of potential toxic compounds and cancer risk, calamus is not recommended during pregnancy or while breastfeeding.

Side effects, ingredient by ingredient Calamus

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 — Calamus.
  • The most serious interaction on file is rated Moderate.
  • For scale: 1,118 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 calamus, double-check with your doctor or pharmacist if you take any CNS depressants (sedatives, sleep aids, anti-anxiety medications), blood pressure medications, antidepressants (especially MAOIs), heart or psychiatric drugs metabolized by your liver, anticholinergic or cholinergic medications, or acid-reflux medications. The interaction list is extensive—use the search tool on this page for your specific drugs.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Calamus Root Powder is not widely recommended by pharmacists due to cancer risk and a large number of medication interactions. If you're taking any blood pressure, psychiatric, heart, or pain medications—or sedatives of any kind—you need to talk with your doctor or pharmacist before considering this product.

The safety data suggests it's wise to avoid it altogether, especially during pregnancy or while nursing.

How can one product interact with so many drugs?
Calamus Root Powder 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.
Is calamus safe to use?
No. Calamus is considered likely unsafe because it may increase cancer risk, and some forms contain beta-asarone, a compound the FDA banned from food. It's not recommended.
Can I take calamus while pregnant or breastfeeding?
No. The safety data rates calamus as likely unsafe in both pregnancy and lactation. It may affect the uterus and contains potentially toxic compounds. Talk with your doctor or pharmacist before considering any herbal product during pregnancy or nursing.
What are the side effects of calamus?
The most common side effects are nausea and vomiting. Rare but serious effects include intestinal paralysis and a rapid heartbeat (tachycardia). There's limited data overall, but the cancer risk is the biggest concern.
Does calamus actually work for bronchitis or asthma?
We don't have reliable evidence to say it does. The data available isn't strong enough to rate whether it's effective for these or other conditions.
How does calamus interact with so many medications?
Calamus acts as a depressant in your central nervous system and can inhibit enzymes in your liver that break down many common drugs. It also affects your body's use of acetylcholine, a chemical messenger involved in many drug actions. That's why it touches so many medication types.
