Padang Cassia and Phenylbutazone

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Phenylbutazone and Padang Cassia in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Padang Cassia safety at a glance

Padang Cassia overall Use caution Generally safe as a food spice, but cassia cinnamons contain coumarin that may harm the liver in large or long-term supplement doses.
Pregnancy Use caution Food amounts are likely fine, but avoid concentrated supplement doses during pregnancy without medical advice.
Breastfeeding Use caution Food amounts are likely fine, but there is little safety data on supplement-level doses while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Phenylbutazone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Phenylbutazone is filed under 5 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates. Padang Cassia has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), cytochrome p450 3a4 (cyp3a4) substrates (moderate) and hepatotoxic drugs (moderate) — and none of Phenylbutazone’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Padang Cassia Itself Has Been Linked To

This is not an interaction — nothing below involves Phenylbutazone. It is the side-effect record for Padang Cassia on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Padang Cassia, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Liver problems Worth acting on Additional detail

    “Orally, Padang cassia appears to be well tolerated. No adverse effects have been reported in clinical trials when Padang cassia is used alone. When Padang cassia extract is used with banaba leaf extract in a specific combination product (Inlacin, Dexa Medica), adverse effects reported in clinical trials have included dizziness, headache, tremor, palpitations, weakness, diaphoresis, and stomach upset.”

    “Padang cassia contains coumarin. There is some concern that ingesting large amounts of Padang cassia might cause hepatotoxicity in some people due to its coumarin content. In otherwise healthy humans, very high doses of coumarin, from 50-7000 mg daily, can result in hepatotoxicity that resolves when coumarin use is discontinued.”

About Padang Cassia

What is Padang Cassia?

  • Adding flavor to food
  • Digestive upset
  • Blood sugar support
  • Antimicrobial purposes
  • Antioxidant support

Padang Cassia is a type of cinnamon (Indonesian or Korintje cinnamon) grown mainly in Indonesia and used widely as a kitchen spice. As a supplement, evidence for health benefits like blood sugar control is limited and mixed, and like other cassia cinnamons it naturally contains coumarin, which can be harmful to the liver in large amounts. Use food amounts freely, but talk to a pharmacist or doctor before taking concentrated cinnamon supplements.

Cinnamomum burmannii · Lauraceae · Inner bark (and bark-derived essential oil) · Ground spice, dried bark sticks (quills), capsules, powder, extract, essential oil, tea

An interaction check asks whether these two react with each other — it does not ask whether Padang Cassia is a good idea for someone in your situation. Here is what our Padang Cassia record says about it on its own.

Padang Cassia: dosing

There is no official, standardized dose of Padang Cassia for any health condition. Amounts used in studies vary widely and are not specific to this species.If you choose to use a cinnamon supplement, follow the directions on the product label and do not exceed the recommended amount. Because cassia cinnamons are higher in coumarin, it is wise to keep concentrated supplement doses low and to avoid taking them every day for long periods.Using Padang Cassia as a normal cooking spice is a low-risk way to enjoy it.
