Lemon balm is said to soothe symptoms of stress, help you to relax, and boost your mood.

Studies found that taking lemon balm eased the negative mood effects of laboratory-induced psychological stress. Participants who took lemon balm self-reported an increased sense of calmness and reduced feelings of alertness.

Although this was a double-blind, placebo-controlled study, it had a small sample size of 18 people. Further research is needed to elaborate on these findings.
