Corvalol

Corvalol is a tranquilizer based on the barbiturate phenobarbital and containing various natural components, such as herb valerian root, as well as peppermint oil Mentha piperita and hop extract Humulus lupulus, popular in Eastern Europe and the former Soviet Union as a heart medication. It is available as a transparent liquid with a characteristic strong aroma, and as white bi-concave scored tablets. In Russia it is sold without prescription, despite the fact that ordinary phenobarbital tablets are sold strictly by doctor's prescription. While not available for sale in all of the Western countries, Corvalol is sometimes brought over from Eastern Europe for self-administration to other countries of residence. Corvalol contains documented amounts of psychoactive chemicals, and may interact with other prescription medications that a person is taking.
