Lemon Balm and Passionflower: Herbal Calmers for Bedtime
These two herbs show up in nearly every 'calm' blend on the shelf. What the evidence says about lemon balm and passionflower for evening anxiety and sleep — and how they're best combined.
Key takeaways
- Lemon balm (melissa) reduces stress and improves mood in several trials, with mild sedative effects at higher doses.
- Passionflower shows modest sleep-quality improvements in studies, comparable to some low-dose sedatives in small trials.
- The two are frequently combined in teas and extracts; the combination may be more effective than either alone.
- Typical use: passionflower tea or 300–500 mg extract, lemon balm 300–600 mg, taken 30–60 minutes before bed.
- Both are generally safe short-term; avoid with thyroid conditions (lemon balm) and sedating medications without advice.
