Maybe, although there is not much research in this area. One 2015 randomized clinical trial in 71 people in Iran with benign heart palpitations who took either a placebo or 1,000 mg of freeze-dried lemon balm extract for 14 days found that, in the 55 participants who completed the study, the participants who took lemon balm reported less-frequent palpitations than the participants who took the placebo. The number of participants in the lemon balm group with anxiety and insomnia also decreased more than in the placebo group.[1] However, this was a single study; more research is needed.
