The bottom line No known interaction

We found no known interaction between Indian Cassia and Ivabradine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Ivabradine states a food rule worth keeping to.

Interaction report

Indian Cassia and Ivabradine

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 Ivabradine and Indian 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.

Indian Cassia overall Use caution Generally safe as a food spice, but concentrated supplements and oils are not well studied.

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

How we checked

Why No Interaction Is Listed for Ivabradine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ivabradine is filed under 3 classifications — including cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Indian Cassia has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and diuretic drugs (moderate) — and none of Ivabradine’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 Ivabradine’s Own FDA Label Lists

This is not an interaction — none of it involves Indian Cassia. These are the most notable effects listed in the ADVERSE REACTIONS section of Ivabradine’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 7 of them are worth acting on rather than waiting out — marked below.

  • A slow heartbeat Worth acting on
  • Heart failure Worth acting on
  • Fainting Worth acting on
  • An irregular heartbeat Worth acting on
  • Raised blood pressure Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on
  • Blurred vision
  • A fast or pounding heartbeat
  • Low blood pressure

From the ADVERSE REACTIONS section of the FDA label for Ivabradine. Read the label on DailyMed › Indian Cassia’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Indian Cassia side to compare — that is a limit of the record, not a statement that Indian Cassia has no side effects.

How to take them

Some Ivabradine Products Have a Food Rule — Indian Cassia Should Not Break It

At least one FDA label for a product containing Ivabradine says to take it with food. If you take Indian Cassia on an empty stomach out of habit, keep them separate — and take Ivabradine with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Ivabradine products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

DOSAGE AND ADMINIST R ATION Adult and pediatric patients greater than 40 kg Starting dose is 2.5 (pediatrics and vulnerable adults) or 5 mg twice daily with food.

From the Dosage and Administration section of the FDA label we read for Ivabradine — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

About Indian Cassia

What is Indian Cassia?

  • Flavoring food
  • Digestive upset
  • Blood sugar support
  • Cold and cough relief
  • Antimicrobial

Indian Cassia (Cinnamomum tamala), also known as Indian bay leaf or tejpat, is an aromatic leaf used widely as a cooking spice and in traditional medicine across South Asia. Human evidence for its health benefits is very limited, so it is best enjoyed as a culinary spice rather than relied on to treat any condition. Used as food it is generally well tolerated, but talk to your pharmacist or doctor before using concentrated supplements or oils.

Cinnamomum tamala · Lauraceae · Leaves (often called tejpat or Indian bay leaf) and bark · Whole dried leaves used in cooking, powder, tea, and essential oil

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

Indian Cassia: dosing

There is no established standardized medicinal dose for Indian Cassia. As a spice, people use small amounts of the dried leaf to flavor cooking, which is the most common and best-understood use.For capsules, powders, teas, or oils, follow the directions on the product label, since strength varies between products.

About Ivabradine

What Is Ivabradine Used For?

Brand names: Procoralan, Coralan, Corlentor, Corlanor

Ivabradine (including the brand Corlanor) is used in adults with stable, symptomatic chronic heart failure with reduced pumping function to reduce the risk of being hospitalized for worsening heart failure. It is prescribed when the heart is beating too fast at rest and the patient is either already on the highest tolerated dose of a beta-blocker or cannot take one.

Corlanor is also approved to treat stable, symptomatic heart failure caused by dilated cardiomyopathy (an enlarged, weakened heart muscle) in children ages 6 months and older who have an elevated heart rate.

Taking Indian Cassia and Ivabradine Together: Common Questions

Is it safe to take Indian Cassia with Ivabradine?

At least one FDA label for a product containing Ivabradine says to take it with food. If you take Indian Cassia on an empty stomach out of habit, keep them separate and take Ivabradine with a meal where the label says to.

Ivabradine is filed under 3 classifications, and Indian Cassia has documented interactions with 2 drug classes — none of Ivabradine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
