Validol is a mild sedative drug popular in Russia and other CIS countries. The active ingredient of Validol tablets is menthol and Menthyl isovalerate, which is an ester of isovaleric acid.
Validolum was patented in Germany in 1897. It was a 30% menthol solution in menthyl isovalerate, produced in small batches from natural ingredients – valerian root and peppermint. Its formulation hasn’t undergone significant changes since then. The mass-scale production started forty years later in the Soviet Union, where Validol found its wide usage and began to gain popularity. Despite the subtle effects and the fact that 120 years passed since its invention, it is still one of the most popular sedatives in Russia. The possible reasons for that are the safeness and the low price.
