Sceletium tortuosum is the botanical name of the plant often called kanna. That name identifies a source, but it does not tell you how a finished extract was prepared or how much of it is in a tablet. Those details belong on the product label and supporting records.
Plant, extract and tablet
Whole plant material and a concentrated extract are different ingredients. A tablet can also include flavoring, sweeteners, binders and other actives. When comparing listings, first confirm that both name the same plant, then note the form actually used.
What does a percentage mean?
Some extracts specify a percentage of mesembrine or a group of mesembrine-type alkaloids. That figure is not the same as the extract weight in milligrams. It may be a target specification rather than a result measured in the particular batch. Read the wording and the certificate of analysis before multiplying numbers or comparing products.
A consistent reading order
Find the serving size, the extract amount per serving, the stated standardization, and the full list of ingredients. Check the warnings and whether the available laboratory document matches the product batch. This order prevents a tablet's total weight or a marketing phrase from being confused with a measured active amount.
Human research on Sceletium is still small, and product compositions vary. Botanical identity alone does not establish a predictable effect. The label is most useful as a precise description of what the seller claims is in that specific formula.
