Rhodiola rosea is an adaptogenic herb traditionally used in Eastern Europe and Asia to enhance resilience to stress and fatigue. More recently, it has been investigated for its potential effects on mood regulation, including mood swings. Several small clinical studies and preclinical research suggest that Rhodiola may have a positive influence on mood, particularly in cases of mild to moderate depression and stress-related symptoms. The proposed mechanisms include modulation of neurotransmitters such as serotonin, dopamine, and norepinephrine, as well as reduction of cortisol levels, which may help buffer the physiological impacts of stress.

However, direct evidence specifically targeting “mood swings” (as distinct from depression or anxiety) remains limited. Most clinical trials have focused on depressive symptoms, burnout, or generalized stress rather than mood instability or bipolar symptoms. The available human studies are generally small, short-term, and sometimes lack rigorous controls. A few randomized controlled trials (RCTs) have shown modest improvements in depressive symptoms and emotional stability compared to placebo, but these findings are not robust enough to be considered high-quality evidence for the treatment of mood swings specifically.

In summary, while there is some scientific rationale and preliminary evidence supporting Rhodiola’s use for mood regulation, the evidence base is not strong, and further research is needed to clarify its role in managing mood swings specifically. Its use for this purpose is best described as “promising but unproven.”
