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

No Health Canada licensed natural health product in the snapshot names this species as a medicinal ingredient under this exact binomial. Absence here means absence from this one register under this one name, not absence from trade, and not a safety verdict.

Recorded constituents

What analytical work has found in this species, at which plant part and preparation. A measured constituent is a fact about material, not about effect.

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.
