| The effects of Rhodiola rosea extract on serotonin level, cell proliferation, and quantity of neurons in the brain hippocampus. | The results showed that Rhodiola rosea extract can improve the level of 5-HT in the hippocampus of depressed guinea pigs, and that a low dosage of Rhodiola rosea can induce the proliferation of neural stem cells in the hippocampus to return to the normal level, repairing damaged neurons in the hippocampus. | Q.

| Effects of Rhodiola rosea L. extract on behavioral and physiological changes induced by chronic mild stress. | The effects of the extract are comparable to those of fluoxetine (antidepressant). Interestingly, neither Rhodiola nor fluoxetine affects the behavioral and physiological parameters tested in non-stressed animals. These results showed that chronic administration of Rhodiola results in potent inhibition of behavioral and physiological changes induced by chronic exposure to mild stressors. | L. Mattioli, C.
