20. Passion Flowers (Passiflora)
- Medicinal Use: Anxiety, Sleep Issues
Passion Flowers are part of a huge family of around 550 species. Since there are so many of these medicinal plants out there, you’ll likely see them pretty much anywhere. People can use these flowers as a small sedative. We can technically call dried extract from the plant a dietary supplement in some countries.

One can use this to help slightly with anxiety and hyperactivity issues due to their sedative effect. However, pregnant women need to be careful when using them because they apparently can induce contractions. Despite this, they can also cause some nausea, dizziness, and abnormal heart rhythms among other things.
