Lemon Balm (Melissa officinalis)
A bright, lemony mint with quiet but real calming and cognitive effects. Useful for daytime anxiety without sedation.
Moderate for anxiety, sleep quality, and mild cognitive support. Some evidence for hyperthyroid symptom relief (mild TSH reduction). Effects: 1–4 weeks.
Melissa officinalis is a member of the mint family used since the Middle Ages for nervousness and 'melancholy.' Its rosmarinic acid and triterpenes mildly inhibit GABA breakdown and modulate acetylcholine — producing calm focus rather than sedation. RCTs support reduced anxiety, improved mood, better sleep quality, and modest cognitive improvements. Pleasant taste; works well as a tea as well as extract.
