- The dried aerial parts of passion flower (Passiflora incarnata) have historically been used as a sedative and hypnotic (for insomnia) and for "nervous" gastrointestinal complaints. However, clinical evidence supporting any therapeutic use in humans is lacking. Early evidence suggests that passion flower may have a benzodiazepine-like calming action.
- Evidence for significant side effects is also unclear, and is complicated by the variety of poorly classified, potentially active constituents in different Passiflora species.
- Passion fruit (Passiflora
edulis Sims), a related species, is used to flavor food.
