Walk into a supplement store and pick up an herbal product. On the label, you might see familiar ingredients such as ginseng, echinacea, plantain, hawthorn, garlic, or mint.
At first glance, that seems straightforward. You know what plant you're getting.
But do you?
One of the most important lessons in botanical medicine is also one of the easiest to overlook: a common plant name isn't necessarily enough to establish botanical identity.
Behind that familiar name is a scientific identity—and when you're evaluating the quality of an herbal supplement, that distinction matters.
Common Names vs. Latin Binomial Names
Plants are scientifically identified using a two-part botanical name known as a Latin binomial:
Genus species
For example, one of the plants I've recently worked with in my herbal studies is broadleaf plantain:
Plantain — Plantago major
The genus, Plantago, identifies a group of closely related plants. The species, major, narrows that identification further.
Why bother with a scientific name when “plantain” is much easier to read?
Because common names can be surprisingly imprecise.
The same common name may be used for different plants depending on geographic region, tradition, language, or industry. Conversely, one botanical species may have multiple common names.
That creates a problem when we're talking about something intended to be consumed.
In my herbal studies, using the complete Latin binomial is emphasized when first identifying an herb and when researching botanical information. Professional botanical databases are also commonly searched using the scientific name rather than relying solely on a common name.
The reason isn't to make herbalism sound more scientific.
It's about identity.
This Isn't Just an Herbal-School Convention
Botanical nomenclature also matters in the regulated dietary supplement industry.
There is an important distinction here, though.
FDA does not simply require every botanical ingredient on every Supplement Facts panel to be identified by its Latin binomial.
Under FDA's dietary supplement labeling framework, botanical ingredients generally use the standardized common name established in Herbs of Commerce. When no standardized common name is available in that reference, the Latin name must be used.
That distinction is important because it's easy to turn the reasonable statement:
“Latin binomials are important for botanical identification.”
into the inaccurate regulatory statement:
“Every botanical supplement label is required to display a Latin binomial.”
Those aren't the same thing.
FDA has even cited companies for using a Latin binomial where the standardized common name should have been used. However, FDA guidance also allows the Latin binomial to follow the standardized common name in parentheses.
That means manufacturers can follow the required naming convention while also providing consumers with additional botanical specificity.
Plant Part Matters, Too
Knowing the species is only part of botanical identification.
Suppose a supplement contains hawthorn.
The next question should be:
What part of the hawthorn plant?
Berry? Leaf? Flower? Bark?
Those aren't necessarily interchangeable botanical materials.
This came up repeatedly in my recent herbal coursework. Hawthorn was a particularly good example because different parts of the plant were discussed in connection with different constituents and herbal applications.
FDA labeling requirements recognize the importance of plant part as well. For botanical dietary ingredients, the Supplement Facts panel must identify the part of the plant from which the ingredient is derived.
FDA warning letters also show that this isn't merely theoretical. Companies have been cited for failing to identify whether botanical ingredients came from the root, leaves, or other plant parts.
So now our ingredient identity looks more like:
Common name → Latin binomial → plant part
But we're still not finished.
When Botanical Identity Becomes Even More Important
FDA's requirements for New Dietary Ingredient Notifications (NDINs) give us another glimpse into how important precise botanical identification can become.
For an herb or other botanical that is the subject of an NDI notification, FDA requires its name to include the Latin binomial, including the author citation.
FDA's guidance goes further.
Because different parts of the same botanical can have different chemical and physical properties, FDA recommends identifying the plant part—such as the leaf, bark, or root—and identifying unusual forms or specific growing conditions when relevant.
Think about what that tells us.
When botanical identity really matters, simply saying “hawthorn” or “ginseng” doesn't necessarily provide enough information to characterize the ingredient.
A Real-World Example: What Does “Ginseng” Mean?
Ginseng is a particularly interesting example because the familiar common name can obscure some important botanical distinctions.
Several plants within the genus Panax are associated with the name ginseng, including:
Asian ginseng — Panax ginseng
American ginseng — Panax quinquefolius
Then there is eleuthero — Eleutherococcus senticosus, a plant historically referred to as “Siberian ginseng” even though it does not belong to the genus Panax.
In fact, U.S. federal law restricts use of the term “ginseng” on an herb or herbal ingredient to plants classified within the genus Panax.
This is a perfect example of why scientific identity matters.
A consumer could encounter plant names that sound closely related while botanical taxonomy tells us they aren't even members of the same genus.
Common names help us communicate. Scientific names help us identify what we're actually talking about.
A COA Doesn't Replace Knowing the Plant
This subject has become particularly interesting to me because my professional work in dietary supplement Quality usually approaches botanical ingredients from another direction.
We look at things such as specifications, Certificates of Analysis (COAs), supplier documentation, identity testing, assays, microbiological results, and contaminant testing.
My herbal education is adding another layer: learning the actual plant material.
Recently, I conducted organoleptic evaluations of several dried botanicals, examining their:
appearance • color • texture • aroma • taste • behavior when prepared in hot water
The purpose isn't to replace analytical testing.
It's another form of familiarity with the material.
In my herbal coursework, we're working with authenticated botanical samples so we can develop detailed sensory descriptions and establish reference points for recognizing botanical materials in the future.
That distinction is important.
Organoleptic evaluation and laboratory identity testing aren't competitors. They provide different kinds of information.
And the deeper I get into botanicals, the clearer it becomes that quality rarely comes down to one document, one test, or one number.
The Ingredient Name Is Only the Beginning
Imagine two bags of botanical raw material arriving at a supplement manufacturer.
Both say the same thing on the outside.
Are they necessarily equivalent?
Not from the name alone.
A much more complete botanical-quality investigation might eventually ask:
Common name → Latin binomial → plant part → geographic origin → growing conditions → harvest timing → post-harvest handling → sensory characteristics → processing/extraction → specifications → identity testing → standardization
And even that doesn't answer every possible quality question.
That's why I've become increasingly interested in following supplement ingredients backward—not merely asking what's listed on the Supplement Facts panel, but understanding where the ingredient came from, what it actually is, how its identity was established, how it was processed, and what evidence supports its quality.
I call this approach Ingredient Intelligence.
What Should Consumers Look For?
You certainly don't need to become a botanist to purchase an herbal supplement.
But the next time you pick up a botanical product, look beyond the marketing on the front of the bottle and examine the Supplement Facts panel.
Instead of asking only:
“Does this contain hawthorn?”
Try asking:
Which species?
What plant part?
Is it whole botanical material or an extract?
If it's an extract, is it standardized to anything?
How does the company establish botanical identity?
Those questions tell you considerably more than a beautiful picture of a plant on the front of a bottle.
And there's an important lesson for supplement companies here, too:
Regulatory compliance and maximum botanical transparency aren't necessarily the same thing.
A company can meet the applicable naming requirements while still choosing to give consumers additional useful information about the botanical ingredients they're purchasing.
The Bottom Line
The Latin name of an herb isn't there just to make a supplement label look scientific.
It's an identity tool.
The common name helps us communicate.
The Latin binomial helps clarify which plant we're talking about.
The plant part tells us which botanical material we're using.
And from there, questions about sourcing, processing, testing, and standardization help us understand the ingredient even further.
So when you see an herbal supplement, don't stop at:
“What's the herb?”
Start asking:
“What plant is actually in this supplement?”
Because with botanical ingredients, the name on the bottle is only the beginning.
