Valerian
Valerian is a perennial flowering herb native to both Europe and Asia. The usage of Valerian has been ongoing since ancient Greece, with ancient Greek physicians, such as Hippocrates and Galen, using it to help with insomnia.
It was also used in 16-17th Century England to help with croup and other severe coughs, along with being used to help with headaches. Finally, the plant was also described as an anticonvulsant. However, it is the use of Valerian for insomnia and other sleep related difficulties which has continued into modern day life.
