Put two kanna products side by side and the labels can look like they were written in different languages. One says 10:1. Another says "standardized to 3% total alkaloids." A third prints 500 mg on the front and leaves you to work out what the 500 mg refers to. All three may be accurate, and you still can't compare them until you know what each number measures.
This guide covers how potency appears on kanna extracts, how extracts differ from gummies, what many people report about onset, and how to read a third-party lab report. It doesn't cover how much to take. That question belongs to the label on the specific product in your hand, and labels differ more than you might expect.

What are kanna extracts?
From plant to extract
Kanna is the common name for Sceletium tortuosum, a low-growing succulent native to South Africa. The San and Khoikhoi peoples of southern Africa have a long history of using it, traditionally by chewing the prepared plant. European written accounts date to the 1600s, and the practice is older than those accounts.
An extract is a concentrated preparation of that plant. A maker processes a larger amount of dried kanna into a smaller amount of material, which changes how much of the plant's active compounds sit in each milligram. Label reading matters more with an extract than with plain dried herb for that reason. A small difference on paper can be a large difference on the scale.
The alkaloids behind the label
The compounds in question are alkaloids. Mesembrine is the one named most often, alongside mesembrenone, mesembrenol and mesembranol. When a label or lab report mentions potency, it almost always means these alkaloids, either one at a time or added together as "total alkaloids."
Research on them is still early. Laboratory studies have looked at how mesembrine and its relatives interact with the body's signaling systems, and a handful of small, short human studies have tested one standardized extract. Nobody has settled how the alkaloids work together, whether the balance between them matters, or how well findings from one extract carry over to another. That's worth remembering when a product implies its particular alkaloid profile does something specific.
How to read potency labels on kanna extracts
Extract ratios (10:1, 20:1, and so on)
A ratio tells you roughly how much plant material went into the extract. In a 10:1 extract, about ten parts of dried kanna were used to make one part of extract. A 20:1 used about twenty.
A ratio does not tell you alkaloid content. Kanna plants vary with growing conditions, harvest and preparation, so the starting herb behind one 10:1 can carry much more or much less mesembrine than the herb behind another. The ratio describes the process. Two extracts with the same ratio can be quite different products, and a 20:1 is not automatically twice a 10:1.
Standardized alkaloid percentages
"Standardized" means the maker has adjusted the extract to contain a stated amount of a specific compound, batch after batch. A label might read "standardized to 3% total alkaloids" or "5% mesembrine." The math is simple: 100 mg of a 3% extract contains about 3 mg of alkaloids.
This is usually the more comparable number, with one catch. Total alkaloids and mesembrine are different measurements. A 3% mesembrine extract and a 3% total alkaloid extract are not equivalent, because mesembrine is only one part of the total. Compare like with like.
Milligrams per serving vs. per package
Two questions clear up most milligram confusion.
The first is "milligrams of what?" A label that says 50 mg kanna extract is giving you the weight of the extract, and the alkaloids are a fraction of that. A label that says 5 mg mesembrine is giving you the weight of the alkaloid itself.
The second is "per what?" Front-of-pack numbers often describe the whole container. A pack that says 300 mg and holds 10 gummies works out to 30 mg per gummy. The per-serving figure is on the supplement facts panel on the back.
Terms without a standard definition
"Full spectrum," "high potency," "extra strength" and similar phrases have no agreed meaning across kanna makers. One company's full spectrum may mean the extract keeps a range of the plant's alkaloids. Another may use the phrase loosely. These terms aren't necessarily misleading, but you can't compare them until you find the numbers behind them.
| Label term | What it tells you | What it doesn't |
|---|---|---|
| Extract ratio (10:1) | How much plant material was concentrated into the extract | How much alkaloid is in each serving |
| Standardized to X% total alkaloids | The share of the extract's weight made up of all measured alkaloids | The balance between mesembrine and the others |
| Standardized to X% mesembrine | The share of the extract's weight that is mesembrine | The amounts of the other alkaloids |
| mg per serving | The weight of extract or alkaloid in one serving | Which of the two it means, unless the label says |
| "Full spectrum," "high potency" | How the maker chooses to describe the product | A measurable amount |
Kanna extracts vs. kanna gummies
Extracts and gummies are different experiences, in the way a kava tea and a kava extract are. (We compare those formats in our guide to kava powder, gummies and extract.)
Kanna extracts are concentrated and often sold in formats you measure yourself, so the label's serving directions do a lot of work. The extracts we carry from Kanna Extract Co. include Lift, Lift XR, Bliss and Rest. Each has its own label, and a shared brand name is no reason to assume a shared serving size.
Kanna gummies are pre-portioned. The measuring has been done for you, and in exchange you get extra ingredients: sweeteners, flavoring, sometimes other botanicals. The SOHI kanna gummies in our shop come in four flavors (Electric Blue Razz, Mango Dream, Peach Glow and Watermelon Wave). Gummies look and taste like candy, so keep them in locked storage, out of reach of children and pets.
| Kanna extracts | Kanna gummies | |
|---|---|---|
| Measuring | You measure each serving, following the label | Each piece is pre-portioned |
| Reading the label | Ratio or standardization, plus serving size by weight | Extract or alkaloid amount per gummy and per pack |
| Other ingredients | Usually few | Sweeteners, flavors, sometimes other botanicals |
| Convenience | More steps, more flexibility | Simple to carry and portion |
Kanna also comes as capsules, tinctures and beverages. The same label questions apply to all of them.
Onset: what many people report
Why format matters
Many people report that kanna held in the mouth, as some extracts and tinctures are meant to be, comes on sooner than kanna that is swallowed and digested, like a gummy or capsule. Kanna-specific timing data is thin, though, and published research hasn't mapped onset by format in any detail. Treat an exact number of minutes you read online as one person's experience.
Check the label for how the product is meant to be taken. The directions vary by product, and the format alone won't tell you.
Why your experience may differ
What you've eaten, your own body, the setting and the concentration of the product all shift how and when people notice kanna. Two people can report very different things from the same product, and some report noticing very little the first time.
Slower formats call for patience. A common misstep with edibles of any kind is taking more because nothing seems to have happened yet. Start gently, stay with the serving and timing guidance on the label, and pay attention to your own experience instead of someone else's timeline. If you ever take more than you intended, effects vary and pass with time, and anyone who is worried should contact a medical professional or Poison Control.
How to read kanna lab results
What a certificate of analysis is
A certificate of analysis, or COA, is a report from a laboratory describing what it found in a specific batch of a product. "Third-party" means the lab is independent of the company that made or sells the product. A COA is the closest you can get to checking a label's claims yourself. The method is the same across botanicals, and our guide to reading the label and COA on muscimol gummies applies it to a different product.
Step 1: match the batch
Find the batch or lot number on your package and look for the same number on the report. A COA for a different batch describes a different product.
While you're at the top of the page, note the lab's name and the test date. An accredited lab usually lists its accreditation (ISO/IEC 17025 is the common standard for testing labs), and a named lab is one you can look up.
Step 2: check the potency panel
The potency section lists the alkaloids the lab measured, usually mesembrine and often mesembrenone, mesembrenol and mesembranol. Results appear as a percentage or in milligrams per gram. The two convert easily: 1% equals 10 mg per gram.
Compare the result to the label. If the label says 3% total alkaloids and the lab found something close, the claim holds up. Small differences are normal because plants vary and so do measurements. A large gap in either direction is worth a question to the seller. Testing methods for kanna alkaloids are also less standardized than those for better-studied botanicals, so two labs may not land on identical figures for the same material.
Step 3: check the contaminant panels
Potency is half the report. The other half covers things that shouldn't be in the product:
- Heavy metals such as lead, arsenic, cadmium and mercury, which plants can take up from soil
- Microbials, including salmonella, E. coli, yeast and mold
- Pesticide residues from cultivation
- Residual solvents left over from extraction, which matter more for an extract than for dried herb
"Pass" means the result fell under the limit the lab tested against. "ND" stands for not detected: the lab's method didn't find the substance. You may also see "<LOQ," which means below the limit of quantitation. A trace may be present, but at a level too low for the lab to measure reliably.
Signs a report deserves a second look
- No batch or lot number, or one that doesn't match your package
- No lab name or contact details
- A test date far older than the product could plausibly be
- A potency-only report with no contaminant panels
- Alkaloid results that sit well away from the label claim
- A cropped image or a summary with the full pages missing
None of these proves a problem. Each is a reason to ask before you buy.
A quick checklist before you buy
- Find out what the main number measures: a ratio, a standardized percentage, or milligrams of extract or alkaloid.
- Check whether milligram figures are per serving or per package.
- Look for the numbers behind phrases like "full spectrum" and "high potency."
- Ask for the COA and match its batch number to the package.
- Confirm the report includes contaminant panels as well as potency.
- Read the label's serving and timing directions before you open the product, and start gently.
- Plan for locked storage, out of reach of children and pets.
FAQs
What does a ratio like 10:1 mean on a kanna extract?
A ratio describes roughly how much dried plant went into the extract. A 10:1 used about ten parts kanna to make one part extract. It says nothing about alkaloid content, so two 10:1 kanna extracts can differ. Look for a standardized percentage or a lab report alongside the ratio.
Are kanna extracts stronger than kanna gummies?
It depends on the specific products. An extract is concentrated, but a gummy contains extract too, and the amount per piece varies by maker. Compare the alkaloid content per serving on each label or COA instead of assuming one format outranks the other.
How soon do people report noticing kanna extracts?
Many people report that kanna held in the mouth comes on sooner than kanna that is swallowed, but reports vary widely and published research hasn't mapped onset by format in detail. Check how your product is meant to be taken and follow the timing guidance on its label.
How do I know a lab report matches my product?
Match the batch or lot number printed on your package to the number on the COA. Then check that the product name, the lab's name and a reasonably recent test date all appear. If the numbers don't match, the report describes a different batch.
Does a higher number mean a better kanna extract?
No. A higher ratio or percentage means a more concentrated extract, which changes how it should be measured. Whether that suits you is a separate question. A clearly labeled product with a matching lab report tells you more than a large number on the front.
Take your time with the label
