Quick Answer
Melissa Sleep Quality Randomized Trial has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: Elevated or blunted cortisol levels have been associated with impaired sleep quality, heightened emotional distress, and reduced mental well-being in both clinical populations and non-clinical models (,,).
Key Takeaways
- 01Elevated or blunted cortisol levels have been associated with impaired sleep quality, heightened emotional distress, and reduced mental well-being in both clinical populations and non-clinical models (,,). [Mazzola Giuseppe (2026)]
- 02Experimental models suggest that rosmarinic acid, the main bioactive compound of, can reduce stress-induced corticosterone elevations, which may translate into improved sleep architecture and psychological outcomes (,). [Mazzola Giuseppe (2026)]
- 0314 16 16 17 In a recent clinical study, 3 weeks of daily supplementation with Melissa extract formulated in phospholipids (Melissa Phytosome™, as Relissa™) was associated with significant improvements in sleep quality, depression, stress, affective states, and quality of life in adults with emotional distress at the daily dose of 400 mg (–).

- Historical use of medicinal plants was a result of cumulative trial and error experience and the transmission of traditional knowledge between generations, which later inspired systematic efforts to turn empirical claims into evidence-based arguments []. [Cîmpeanu Ioan-Alexandru (2026); evidence level 4]
Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
