Synonym : - S. longifolia Schrad. ex DC. With good reason, many authors have taken a generic approach to Solidago. EFS aggregates S. odora and S. virgaurea. PH2 confesses that S. canadensis, C. gigantea, and S. virgaurea have been interchangeably mixed in the market. Few of the compilers, including yours truly, could positively identify which species is in the apothecary jar, and probably none of the chemical studies are vouchered. While I have maintained citations for several species, I think the identities are all suspect.
Dosages (Canadian Goldenrod) : - 6 - 12 g powdered herb (PH2). Also drink at least 2 liters water (PH2).

Irrigation therapy contraindicated in edema resulting from reduced cardiac and/or kidney function. Possibly allergenic (PH2). Hazards and/or side effects not known for proper therapeutic dosages (PH2).
