Synonyms are carried from the source compendium. A species may be traded and studied under more than one name, which is exactly how a safety record gets lost.

Regulatory presence

Health Canada's Licensed Natural Health Products Database holds 1,776 licensed products naming Lepidium meyenii as a medicinal ingredient, matched on the exact Latin binomial. A licence records that a product met the regulator's requirements for sale in Canada. It is not evidence that the product works.

Boundary

A constituent measurement is a fact about material at a stated preparation, not a statement about what that material does in a person. An adverse-effect or genotoxicity record is an observation reported in a source, most often in an animal or laboratory model. Neither is a Metatron Health conclusion about causality, human risk or benefit, and the absence of a record is not proof that a preparation is safe. Nothing here is diagnosis, prescribing or individual medical care.
