Salix pentandra
The EFSA Compendium of Botanicals holds 7 constituent measurements for Salix pentandra. This page reports what those source records contain and how to reach them. It carries no effect estimate, no dose and no recommendation.
Accepted name in source: Salix pentandra L.
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.
