Corvalol

thumb|Corvalol

Corvalol (Корвалол, Corvalolum, Korvalol) is a tranquilizer based on the herb valerian (Valeriana officinalis) root, as well as peppermint oil Mentha piperita, hop extract Humulus lupulus, and the barbiturate phenobarbital, 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. While not available for sale in 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.
