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 46 licensed products naming Handroanthus heptaphyllus 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.

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.
