Passion flower is commonly recommended by doctors as a mild sedative for those suffering from insomnia or nervous exhaustion. Combining valerian root with other mildly sedating herbs like passionflower is quite common.
Nonprescription sleep aids are typically considered natural. They encourage relaxation, ease anxiety, and promote sleep. Many natural sleep aids are also linked to other health-promoting behaviours like improved digestion and pain relief.
Some researchers believe that passionflower supplements may help treat anxiety, insomnia, and certain forms of pain because it may increase levels of gamma-aminobutyric acid (GABA), a chemical the brain makes to help regulate mood. Valerian is often called natures Vallium, it can help reduce stress and acts as a natural sedative.
