Peppermint

• In a study by the USDA, peppermint tea was shown to have anesthetic effects on the body, as well as acting as an an analgesic, or pain killer. Since aches and pains can often be disruptions to relaxation and sleep, peppermint tea might help induce calm and slow down the central nervous system. It may also have a calming effect for stress and help relax muscles. Since some peppermint teas contain other herbs with caffeine, it's best to check labels to ensure store-bought tea is made purely from peppermint.
  
  

Kava Kava

• Kava kava tea has long been used as an herbal remedy for insomnia. It may help to promote a deep sense of relaxation and act as a powerful sedative. Kava kava is a sweet tea with a slightly bitter after taste. Although legal in the United States, it has been a topic of controversy since its sedative effects are known to be extremely powerful. It's best to exercise caution when drinking kava kava tea and not drive after consumption.
  
  

Passion Flower

• Passion flower tea has been traditionally used as a sleep aid. In one Australian study, researchers found that participants who consumed passion flower tea had higher-quality sleep than those who did not consume the tea. The tea may help to relieve feelings of restlessness and may also be good for managing symptoms of general anxiety or nervousness. The tea may also help lower blood pressure and act as an an analgesic.
  
  

Valerian Root

• According to Dr. Jennifer Ashton, Valerian root tea can promote sleep and may be a safer alternative than prescription-based sleeping pills. This natural herb is known for its powerful sedative qualities and is often an ingredient in many "bedtime" or "relaxation" tea blends. As a mild tranquilizer, it may be a good option for those with extreme cases of insomnia or chronic sleep disorders. It is known for its pungent smell, which can be offensive or unappetizing for some.
