Rhodiola is a plant from cold regions of Europe and Asia, traditionally used for fatigue and stress.
NCCIH states there isn't enough reliable evidence to rate Rhodiola for any specific use, though it's possibly safe for up to 12 weeks of use.
HorseFil's amount is not published. Rhodiola has a reported interaction with losartan, a blood-pressure drug, worth flagging to your doctor.
