"Valerian has been used as a medicinal herb since at least the time of ancient Greece and Rome. Its therapeutic uses were described by Hippocrates, and in the 2nd century, Galen prescribed valerian for insomnia... In addition to sleep disorders, valerian has been used for gastrointestinal spasms and distress, epileptic seizures, and attention deficit hyperactivity disorder. However, scientific evidence is not sufficient to support the use of valerian for these conditions." \\ | "Valerian has been used as a medicinal herb since at least the time of ancient Greece and Rome.

| Among the many sesquiterpenoid compounds present in V.officinalis root oil, (-)-maaliol sticks out: The higher the content, the finer the character of the scent of the oil. The actual scent carrier proved to be the ester of isovaleric acid with (-)-myrtenol. In addition, the acetates of (-)-myrtenol and (-)-borneol play an olfactory role. \\ |

The flower scent of living V.officinalis does not contain the unpleasant smelling valeric acid or isovaleric acid which are major components of the hydrodistilled flower oil. Headspace samples from unpicked valerian flowers contained lavandulyl isovalarate (15.0%), lavandulyl 2-methylbutyrate (0.6%), and lavandulol (1.6%), (E,E)-alpha-farnesene (7.6%), 3,4-dimethoxytoluene (4.7%), (Z)-3-hexenyl acteate (4.5%), p-methylanisol (3.6%) and methyl eugenol (2.1%). \\ | The flower scent of living V.officinalis does not contain the unpleasant smelling valeric acid or isovaleric acid which are major components of the hydrodistilled flower oil.

"Twenty compounds were identified which accounted for 88.11% of the total oil of V. officinalis... The most abundant compounds were patchoulol (16.75%), α-pinene (14.81%), β-humulene (8.19%) and α-bulnesene (7.10%)... The chemical profiles of the V. officinalis essential oil in this study was different from those of previous reports (i.e., the content of bornyl acetate was analyzed as 11.3% by Pavlovic et al., and the patchoulol | "Twenty compounds were identified which accounted for 88.11% of the total oil of V. officinalis...
