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.

Substance	Plant part	Preparation	Concentration	Analytical method	Source
Ngaione	Leaves	Essential oil	—	—	No resolvable identifier
Ngaione	Unspecified	—	—	Unspecified	No resolvable identifier

Recorded adverse effects

Adverse effects reported in the source literature, most often in animal or laboratory models at a stated preparation and dose.

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.
