An ingredient name needs context. When reading botanical research, ask where the material appears: during extraction, in the dry extract, in the capsule contents, or in the shell. Those are different parts of the preparation.
Watch: four places a material can appear
Accessible transcript
00–06 seconds: Read the preparation. Where does each material appear? A historical kanna study example.
06–12 seconds: Extraction inputs. The paper describes water and ethanol for extraction. This does not give residual solvent in the capsule.
12–18 seconds: Dry extract. The paper separately reports extract-stage excipients. Keep each material attached to its reported stage.
18–24 seconds: Capsule contents. Capsule-stage excipients are another part of the description. Do not invent quantities that were not reported.
24–30 seconds: Capsule shell. The historical study describes a gelatin shell. A study preparation is not a current retail label.
30–36 seconds: Keep the source attached. Check the exact preparation, date and source. This example does not establish Kiody product ingredients.

A historical kanna example
The investigational-product section of a 2013 Zembrin study describes a specific manufactured kanna extract and capsule preparation. It is not a description of ordinary kanna plant material, isolated mesembrine-type alkaloids, every kanna extract, or products sold today. Read Nell and colleagues’ original study.
What the study placed at each stage
- Extraction inputs: purified water and ethanol were reported as the extraction-solvent system.
- Dry-extract stage: the paper reported lactose monohydrate and colloidal anhydrous silica as excipients used with the spray-dried extract.
- Capsule contents: lactose monohydrate, sodium starch glycolate and magnesium stearate were reported as capsule-stage excipients used to reach the final capsule weight.
- Capsule shell: the paper described a size 1 hard-shell gelatin capsule.
These are source-reported roles for the identified historical investigational product. The extraction-solvent description does not by itself measure residual solvent in the final capsule.
Four questions to keep the evidence clear
- Which stage? Keep extraction inputs separate from materials reported in the dosage form.
- Which measurement? A solvent mixture description does not tell you the measured residual solvent in a finished capsule.
- Which preparation? Record the study material and its date before comparing it with another product.
- Which source? A study methods section, a patent example and a current product label answer different questions.
This distinction does not rate an ingredient as beneficial or harmful. It helps prevent a manufacturing description from becoming an unsupported product claim. The historical kanna example also does not establish the composition of Kiody products.
