Evidence notes

Rhodiola crenulata has substantially less clinical research than Rhodiola rosea. Available studies are small, preliminary, or conducted in non-English journals. Salidroside standardization is rational but human efficacy data is limited. Grade C reflects moderate/preliminary evidence with promising signals but insufficient RCT evidence.

Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
