Five levels to keep separate
- Traditional use can guide questions but is not modern clinical proof.
- Composition varies by variety, origin, milling, plant part, and extraction method.
- Laboratory studies explore mechanisms; they do not demonstrate an effect in people.
- Animal doses and conditions may differ greatly from ordinary food intake.
- A human study on one defined material cannot be generalized to every yulmu product.
How the Lab communicates findings
We name the tested material and study design. For example, we write “a laboratory study of an ethanol extract of Coix bran” instead of “yulmu is good for skin.”
- We do not turn cell or animal findings into human health claims.
- We do not use disease-prevention or treatment language for ordinary foods or cosmetics.
- Product claims require evidence for that product and compliance with applicable law.
The long-term evidence archive
The separate Coix 555 project records bibliographic data, material, study type, outcomes, limitations, safety signals, and communication risk. Progress is reported in ten-percentage-point milestones.
