Cinnamomum zeylanicum vs Cinnamomum verum: Are They the Same?

If you have been comparing Ceylon cinnamon supplements or reading research papers, you may have seen two different botanical names: Cinnamomum verum and Cinnamomum zeylanicum.

That can make it look like they are two different types of cinnamon, but in modern botanical classification they refer to the same species.

Cinnamomum verum is the currently accepted scientific name for true Ceylon cinnamon, while Cinnamomum zeylanicum is an older botanical name that is still widely used in research, supplement labels, and older literature.

Is Cinnamomum zeylanicum the Same as Cinnamomum verum?

Yes.

The Royal Botanic Gardens, Kew currently recognizes Cinnamomum verum as the accepted name for the species commonly known as Ceylon cinnamon.

Kew lists Cinnamomum zeylanicum as a synonym of Cinnamomum verum.

So if one supplement lists Cinnamomum verum and another refers to Cinnamomum zeylanicum, the names alone do not indicate that they contain different cinnamon species.

Why Are There Two Scientific Names?

Plant names can change as botanical classification becomes more standardized.

Cinnamomum verum is now the accepted name used by major botanical databases, while Cinnamomum zeylanicum became deeply established in older scientific and commercial literature.

Because older names do not instantly disappear, both names can still be found today.

This is common in botany. A plant may have one currently accepted name while older scientific names remain as synonyms in books, research papers, databases, and ingredient descriptions.

What Does Cinnamomum verum Mean?

Cinnamomum is the botanical genus that includes a number of cinnamon species.

Verum comes from Latin and refers to something being true or genuine, which fits with Ceylon cinnamon's common nickname of "true cinnamon."

Cinnamomum verum is native to Sri Lanka according to Kew's Plants of the World Online.

This botanical identity is what separates genuine Ceylon cinnamon from other types of cinnamon that may look or taste similar.

What Does Cinnamomum zeylanicum Mean?

The word zeylanicum refers historically to Ceylon, the former name for Sri Lanka.

That is why Cinnamomum zeylanicum became such a recognizable name for Ceylon cinnamon.

You will still see it used frequently in research papers because many studies were published using that name.

This can be useful to know when searching scientific databases. Searching only for Cinnamomum verum may not always surface every older paper that used Cinnamomum zeylanicum instead.

Why Do Research Papers Still Use Cinnamomum zeylanicum?

Scientific terminology does not always change at the same speed across every field.

Botanical databases may adopt an accepted name while medical researchers, supplement manufacturers, and older reference materials continue using a familiar synonym.

That is why a paper about Cinnamomum zeylanicum should not automatically be treated as research on a different cinnamon species.

In most cases, the researchers are referring to the same Ceylon cinnamon now classified as Cinnamomum verum.

Does This Matter When Buying Ceylon Cinnamon?

It can.

If a supplement clearly lists Cinnamomum verum or Cinnamomum zeylanicum, that gives you more information than a label that simply says "cinnamon."

The word cinnamon can refer to several different species, including types commonly grouped under the name Cassia.

Those species are not identical to Ceylon cinnamon and can differ in flavor, appearance, and naturally occurring compounds such as coumarin.

For someone specifically looking for genuine Ceylon cinnamon, seeing the botanical species on the label is a useful sign of ingredient transparency.

Is Cinnamomum verum the Same as Cassia Cinnamon?

No.

Cinnamomum verum refers to Ceylon cinnamon. Cassia cinnamon generally refers to other Cinnamomum species.

Although both are sold as cinnamon, they are botanically different plants.

This distinction matters because Ceylon cinnamon is known for having a different natural chemical profile, including considerably lower levels of coumarin compared with many Cassia varieties.

So while Cinnamomum verum and Cinnamomum zeylanicum refer to the same species, neither should be treated as another name for Cassia cinnamon.

Which Name Should Be on a Supplement Label?

Cinnamomum verum is the most current botanical name, so that is the clearest name to look for.

However, seeing Cinnamomum zeylanicum does not necessarily indicate a problem. It is a recognized synonym and is still commonly used.

Some labels may even show both names to make the botanical identity clearer.

More important than choosing between these two names is making sure the product identifies the species at all.

A label that says only "cinnamon bark" gives you less information than one that clearly identifies genuine Ceylon cinnamon.

Why Botanical Names Matter With Cinnamon

Common names can be surprisingly broad.

Two products can both say cinnamon on the front while containing different cinnamon species.

Botanical names help remove some of that ambiguity.

When you see Cinnamomum verum or Cinnamomum zeylanicum, you know the ingredient is intended to be Ceylon cinnamon rather than a generic Cassia cinnamon ingredient.

This becomes especially useful when comparing concentrated extracts, powders, or supplements where you cannot identify the cinnamon by appearance.

What Should You Look for When Comparing Products?

Start with the botanical identity.

Look for Ceylon cinnamon, Cinnamomum verum, or Cinnamomum zeylanicum.

Then check whether the product uses ordinary cinnamon powder or a concentrated extract.

If it is an extract, look at the extract ratio, serving size, and any raw-herb equivalent shown on the label.

Ingredient transparency and third-party testing can also help when comparing products.

Metabolae Ceylon Cinnamon is one example of a product that uses genuine Ceylon cinnamon in a concentrated extract format.

Why Both Names Still Show Up

The simplest answer is history.

Cinnamomum zeylanicum became deeply established in scientific and commercial literature, while Cinnamomum verum is now the accepted botanical name.

Both may therefore appear when you research Ceylon cinnamon, and seeing one instead of the other does not mean you are looking at a completely different plant.

For practical purposes, the important distinction is not Cinnamomum verum versus Cinnamomum zeylanicum.

The important distinction is genuine Ceylon cinnamon versus other cinnamon species.
