Notes for this study:
||Milford Epworth scale. Mean and SD. Control: before 8.21 (3.57), after 8.04 (4.78). Rhodiola: before 7.05 (3.59), after 6.41 (3.69).
|Number of Subjects
In a randomized, unblinded trial, 80 participants with mild anxiety were allocated to take 200 mg of Rhodiola Rosea twice per day, or no treatment for 14 days.
Funding issues for this study:
The primary outcomes were anxiety as measured by STAI and stress as measured by the perceived stress scale, and there was a small, statistically significant greater reduction in both compared with the placebo group. Additionally, there was a statistically significantly greater reduction for Rhodiola for anger, confusion, and total negative mood, and no statistically significant difference for sleep quality, sleepiness, vigor, tension, fatigue, and depression, though fatigue, tension, depression, sleepiness, and sleep quality saw small, nonsignificant improvements compared with placebo.
Reaction time didn't see a statistically significant improvement.
