Ingredient names

How to read a botanical ingredient name

Last updated October 12, 2026Who wrote and checked this page

An ingredient name is a specification, and most of them are incomplete. A good one tells you which species, which part of the plant, how concentrated the extract is and what it was measured to carry. A poor one gives you a word. This guide takes a botanical row apart element by element, then scores all nine rows of one real panel against it.

Five elements: the common name, the binomial, the plant part, the extract ratio and the standardised constituent. The common name is the least informative and the only one always printed. The product this site documents scores unusually well on the first three — six common names, five binomials, five plant parts across six botanical rows — and poorly on the last two: no extract ratio anywhere, and a standardisation on two rows of six.

The five elements of a botanical row

A botanical row on a Supplement Facts panel can carry five identifying elements, plus the amount. Nothing requires any of the five except the name. Each one that is present makes the row checkable; each one that is absent makes it looser, and the looseness compounds.

01

The common name

Saw palmetto, nettle, pygeum, pumpkin seed. A common name is a word people recognise, and it is the least informative element a row can carry. One common name can cover several species on several continents, and species differ in their constituents. A common name is where a search starts; it is not where a reading ends.

02

The binomial

The genus and species in Latin, conventionally italicised: Serenoa repens, Vitis vinifera, Cucurbita moschata. This is the difference between a row you can look up and a row you can only guess at. Where a genus has several commercially used species, as Cucurbita does, naming the species tells you which material was extracted.

03

The plant part

Root, rhizome, leaf, bark, fruit, seed, aerial parts. Different parts of one plant are studied separately and are not interchangeable: a root extract and a leaf extract of the same species are two materials. A row naming the part has told you which published work applies. A row naming only the plant has left you to assume, and the assumption is often wrong.

04

The extract ratio

A figure such as 4:1 or 10:1, meaning that many parts of raw material produced one part of extract. It says how concentrated a material is, and roughly by how much. It describes the process rather than the result, so it is weaker than a standardisation and much better than nothing. Without it, a milligram of extract and a milligram of raw powder look identical on a label.

05

The standardised constituent

A statement that the extract was manufactured to a fixed proportion of something measurable: 3% phytosterols, 5% lycopene, a stated fatty-acid content. This is the single most informative element a botanical row can carry, because it is what published trials report and therefore the only basis on which a product can be compared with one. It is also the element most often left off.

Those five are not of equal value. The binomial and the plant part tell you which published record applies. The extract ratio and the standardisation tell you what the material is. The amount, printed in the right-hand column, tells you how much of it you are taking. A row carrying all five plus an amount can be compared with a trial; a row carrying the common name alone cannot be compared with anything.

All nine rows, scored element by element

Every row of this panel as the label prints it, with each of the five elements either quoted or marked as absent, and a score out of five for the six botanical rows. The second line of each name is the row exactly as the panel prints it, brackets and all.

Three of five. The missing one that matters is the standardisation: trial extracts are lipidosterolic preparations standardised to a stated fatty-acid content, and this is the largest botanical row on the panel.

Four of five, the best-specified row on the label. The percentage is what turns the 200 mg into 6 mg of phytosterols.
Grape Seed Extract
Grape Seed Extract (Vitis vinifera) (seed)

Three of five. Grape seed extracts are commonly standardised to a proanthocyanidin content, and this row prints none.
Pumpkin Seed Extract

Three of five, and the species is worth noticing: Cucurbita has several commercially used members, so naming moschata tells you which one.
Nettle Extract
Nettle Extract (leaf)
Not publishedLeafNot publishedNot published2 of 550 mg · leaf
Two of five, the weakest row on the panel. No binomial, and the part that is declared is the wrong one for the indication: the prostate literature is on the root.
Boron
Boron (as boron amino acid chelate)
Not a botanical row——Chemical form named: boron amino acid chelateNot scored10 mg · half the adult upper limit
A nutrient rather than a plant. For a vitamin or a mineral the equivalent element is the chemical form, and this row names it.
Lycopene 5%
Lycopene 5% (Lycopersicum esculentum) (tomato)
Lycopersicum esculentumNamed as tomato, which is the plant rather than a partNot published5% lycopene3 of 510 mg at 5% → 0.5 mg lycopene
Three of five. The percentage is printed, which is what shows that 10 mg of preparation is 0.5 mg of lycopene.

Three of the nine rows are nutrients rather than plants and are not scored on the five elements, because the equivalent for a vitamin or a mineral is the chemical form. All three name it: dl-alpha tocopheryl acetate, pyridoxine hydrochloride and boron amino acid chelate. That is the same kind of disclosure as a standardisation, and it is why the vitamin E correction on this site is possible at all.

Prostacyl — 60 capsules, two a dayNine ingredients, each with a printed amount and no proprietary blend — the most transparent panel in this series. 60 or 90 days — the page prints both. From $49 a bottle on the six-pack.

Good at naming, poor at standardising

Add the six botanical rows up and the shape of this label becomes a single sentence. Thirty element slots, six rows times five elements, and eighteen of them are filled.

Read the first three figures and the last two as two different stories. On identification this label is unusually good: it tells you which plant and which part on nearly every row, which is more than most of this category manages and is what makes every finding on this site possible. On measurement it is poor: no extract ratio anywhere, and a standardised constituent on a third of the botanical rows. Identification tells you which literature applies. Measurement tells you whether the capsule is in the same range as that literature.

The third column read as one line is the shape of a complete botanical row: a common name, a binomial, a plant part, a ratio or a standardisation, and an amount. This panel supplies four of those five on its best row and two on its weakest. Each row is taken individually on the ingredients page.

The test that takes five seconds

Count the bracketed phrases in a botanical row. A row with none is almost always a bare name. A row with two is usually carrying a part and a standardisation, which means somebody decided to tell you what is in the capsule. The best-specified row on this panel reads Pygeum africanum Extract (bark) (std. to 3% phytosterols): a Latin name in the open, and two bracketed specifications after it.

What a standardisation buys a reader

Three things, and they are the three you most want. The first is comparability with published work, because trials report the standardisation and not just a name. The second is comparability between products, because two labels printing the same percentage describe materials measured the same way. The third is reproducibility: a standardised material is specified, so next year’s bottle is meant to match this year’s.

The constituent usually quoted for each botanical row here, and whether a figure for it is printed.
RowThe constituent usually quotedPrinted on this label?
Saw Palmetto ExtractA stated fatty-acid content; trial extracts are lipidosterolic preparationsNot published
Pygeum africanum ExtractTotal sterols or phytosterols; trials use 13%Yes — 3% phytosterols
Grape Seed ExtractProanthocyanidins or total polyphenolsNot published
Pumpkin Seed ExtractNo single constituent in common use; the relevant specification is oil against seed against extractNot published
Nettle ExtractVaries by part; the root literature specifies the extraction solventNot published
LycopeneLycopene itself, as a percentage of the preparationYes — 5%

The middle column is useful even where the right-hand column says nothing, because it is the vocabulary to use when asking a seller a question. Not “how much saw palmetto” but “what fatty-acid content is the extract standardised to”. A question in the trade’s own units is much harder to answer with a reassurance. The contact page writes all of them out in order.

Extract ratios, and why a weight is not enough

An extract ratio is the element most readers have never heard of and the one that most often explains a surprising milligram figure. It is written as two numbers with a colon, and it says how much raw material produced the extract in the capsule.

  • 1:1 is not concentrated. One part of raw material produced one part of the named material, so the figure on the label is close to a weight of plant.
  • 4:1 means four parts of raw material produced one part of extract. A milligram of it stands in for roughly four milligrams of the raw plant, by that measure.
  • 10:1 and above are concentrates. The same milligram figure now represents an order of magnitude more raw material, which is why a label omitting the ratio makes two products look alike when they are not.
  • No ratio at all is the commonest case, and it is the case on all six botanical rows here. A row reading Pumpkin Seed Extract (seed) 100 mg could be a lightly concentrated powder or a strong concentrate, and those are not interchangeable at any weight.

A ratio matters most where no standardisation is printed, because then it is the only thing left that describes concentration. Of the three unstandardised botanical rows on this panel — saw palmetto, pumpkin seed and grape seed — not one carries a ratio either. Those rows give you a plant, a part and a weight, and nothing at all about what the weight contains.

Where a standardisation is printed, the ratio becomes a nicety rather than a necessity: a percentage of a measured constituent already tells you what the material carries. That is why the pygeum and lycopene rows can be set against trial doses and the other three cannot. The mechanism page sets each row against the research on it.

The plant part, and the row that proves it

One word, and it decides which published work applies to a row. This panel declares a part on five of its six botanical rows, which is good practice. On one of those five the declared part is the wrong one for the indication, and that is only visible because it was declared.

The part is stated, which is good practice. It is also the wrong part for the indication.

Nettle Extract, as the detail pane on this site puts it

The arithmetic underneath that is short. The panel prints 50 mg of nettle leaf. The root trials used 360 mg a day for six months of aqueous root extract, and up to 1,200 mg a day of methanol root extract. So the row is the wrong part, and about seven times too little even if the part had matched. Two gaps, one word apart.

Hold that against the saw palmetto row, where the part is right. Serenoa repens fruit is the part the clinical literature uses, so naming the fruit is naming the correct material. The difficulty on that row is the missing standardisation rather than the part. Different elements go wrong on different rows, which is why scoring a row element by element is more useful than scoring a label as a whole.

Never guess a species

This is a rule rather than a technique, and it is one of the standing editorial rules of this site. A plant species is not identified from a photograph here, ever.

On this product the rule has one row to apply to. The nettle row prints a plant part and no binomial, and the prostate literature on nettle is specifically on Urtica dioica. It would be easy to write that species into the row and tidy the table up. It is not printed on the label, so it is not printed in the binomial column, and the column says Not published instead. The species named in the discussion of the research is the species the research used, which is a different statement from what is in the capsule.

The same restraint applies to marketing pictures. Flowering plants within one genus can be very difficult to separate from a single image, the image on a graphic was chosen by a designer rather than by a botanist, and nothing published states that the plant in the photograph is the plant in the capsule. An identification made from artwork would be a guess wearing the clothes of a finding.

The same rule, in the other direction

This desk also makes no claim about how any supplied photograph was produced. What can be shown about a set of images is shown — a checksum is a fact anyone can reproduce — and how any individual image came to exist is not something this desk can check, so it is never asserted. The rules for handling photographs and testimonials are published in full on the about page.

Common questions about ingredient names

Six questions about reading a row rather than about this product. Type in the box to filter them.

what does the latin name on a supplement label mean

It is the binomial: the genus and the species, which identify the plant precisely. A common name can cover several species across several continents, and species differ in the constituents they carry, so the binomial is the difference between a row you can look up and a row you can only guess at. Nothing requires a label to print one. On the product this site documents, five of the six botanical rows carry a binomial and the nettle row does not.

why does a label need to say which part of the plant

Because different parts of one plant are different materials and are studied separately. The clearest case in this category is nettle: the benign prostatic hyperplasia literature is on Urtica dioica root, at 360 mg a day for six months and up, while nettle leaf has a separate literature about rheumatic complaints, osteoarthritis pain and allergic rhinitis. A row declaring the leaf has declared a material the prostate trials never used.

what does standardised to a percentage mean

It means the extract was manufactured to hit a fixed proportion of a constituent somebody assayed. It is the most informative thing a label can print about a botanical, because trials report standardisations and a product cannot otherwise be compared with one. Multiply it out: 200 mg standardised to 3% phytosterols is 6 mg of phytosterols, and 10 mg of a 5% lycopene preparation is 0.5 mg of lycopene. Two printed numbers, one multiplication.

what does 4 to 1 extract mean on a supplement

It means four parts of raw material produced one part of the extract in the capsule, so the material is concentrated roughly fourfold against the raw plant. A ratio describes the process rather than the result, which is why it is weaker than a standardisation: two 4:1 extracts made with different solvents from different plant parts need not carry the same constituents. It is still worth having. No extract ratio appears anywhere on the panel this page audits.

what is lycopene 5 percent 10 mg

A preparation, not a constituent. The percentage describes the extract: the material was manufactured to contain 5% lycopene by weight. The milligram figure is the weight of that material in the serving. So 10 mg at 5% delivers 0.5 mg of lycopene rather than 10. Reading it the other way round is the commonest mistake on this kind of row, and it is the reason a standardisation percentage is the element to look for first.

does naming the species mean a supplement is good

No, and the product this site documents is the clearest demonstration of why. It names species on five of six botanical rows and plant parts on five of six, which is unusually good, and four of its nine rows still sit well below the doses the published work used. Naming and dosing are separate judgements. Good naming is what lets you make the second judgement at all, which is why it is worth crediting and why it is not the same thing as a good formula.
