Valerian is a cerebral stimulant, and may be employed wherever a remedy of this character is indicated. It allays nervous irritability, modifies or arrests pain, promotes rest, and favors sleep, where these conditions result from an enfeebled cerebral circulation. It is very extensively used, and many times without benefit, as the condition of the nervous centers is very rarely taken into consideration.
