A single dose of Corvalol ( 1 ml ) contains:

• Phenobarbital - 16 mg
• Bromisovalum ( derivative of bromine and valeric acid ) - 20 mg
• Peppermint oil - 1.5 mg

as well as inactive ingredients:

• Sodium hydroxide ( to convert poorly soluble phenobarbital into phenobarbital sodium )
• Ethanol and water as solutes

Corvalol is nearly identical in both composition and effects to Valocordin, main difference being that Corvalolis manufactured in Eastern Europe, whereas Valocordin is manufactured in Germany. The word "Valocordin" itself is a registered trademark of the German pharmaceutical company Krewel Meuselbach GmbH.

In Eastern Europe, Corvalol is believed to be safe enough to use in recommended doses without prescription. However, both primary ingredients of Corvalol may be considered controlled substances in other countries. For example, it is illegal to import this drug into United States ( see Health Hazard with Unapproved Imported Drug from Russia ).

Phenobarbutal is not listed there, but is present. So, it is illegal for travelers to bring a flask or two when they go to Europe.
