Valerian is a flowering perennial plant with a long history of use a medical herb. Its use in traditional medicine dates back to Ancient Greece where it was used as a treatment for insomnia. Throughout the ages it has been used in a variety of European and Asian cultures as a treatment for colds and flus, and was believed to prevent the black plague in the 13th century. Today, Valerian root extract is produced for uses in the modern medicinal industry, traditional medicine and herbal teas.

plant name


Valerian, catnip


International Latin denomination


Valeriana officinalis L.


botanical family


ex- Valerianaceae

  • Caprifoliaceae according to the APG IV phylogenetic classification


Description and habitat


  • Robust herbaceous plant of damp places
  • Stems hollow, grooved, sometimes reaching 2 m, much branched at the top
  • Basal or cauline leaves, pinnatisect and with toothed lobes
  • Umbelliform terminal cymes of white or pink flowers
  • Common throughout temperate Europe


History and tradition


  • Its name comes from the Latin "valere" = "to be well" (which gave "validity" and "convalescence"), it is present in many traditions (the genus has 200 species)
  • Before the advent of synthetic tranquilizers, valerian root was considered the most effective tranquilizer. In Greek Antiquity, Hippocrates and Dioscorides recommended it to treat insomnia. The Romans used it to combat palpitations and arrhythmia. In the Middle Ages, valerian was recommended as a tranquilizer and sleep aid. From the end of the 16th century, Europeans began to use it to treat epilepsy. Native Americans used it in powder form to calm epileptic seizures. During the First World War, the use of valerian developed to treat nervous shock caused by bombardments. Today, it is cultivated in many countries to meet the demand of the pharmaceutical industry [1]
  • The smell of the root is identical to that of feline urine, hence its name catnip .


Parts used


  • Underground part becoming very fragrant by desiccation, with unpleasant smell: rhizome, root and stolons, carefully dried at a temperature below 40° C
    • "dried underground organs, whole or fragmented, of Valeriana officinalis L. sl, comprising the rhizome surrounded by the roots and the stolons"


Dosage forms available



Usual dosages


  • At 100 mg the dry extract is thymoanaleptic and at 400 mg it is soporific
  • Indication in nervousness, dosage for an adult: 2 capsules of 270 mg morning and evening
  • Maximum dosage: 800 mg of dry extract, corresponding to approximately 4 to 5 g of root powder




Main components of the plant



Main components of buds or young shoots


Main components of essential oil





Plant properties


  • Sleep aid [2] , improves sleep structure and quality [3]
  • Anxiolytic [4] , [5] , by valerenic acid [6] , [7] , [8] , anxiolytic effect accentuated in combination with lemon balm [9] , spasmolytic, sedative, tranquilliser, muscle relaxant and nervous system depressant
  • Valerian extracts show partial agonist activity at the adenosine A receptor (playing a role in neurotransmitter release) [15]
  • Valerian exhibits GABAergic effects through various molecular synergies [16] , [17]  :
    • Low concentrations of valerian extracts enhance the binding of benzodiazepines to the GABA-A receptor, and valerenic acid inhibits the enzymatic degradation of GABA [18] , [19]
    • Valerenic acid also interacts with glutamatergic receptors [20]
  • Other suspected synergies:
  • Decreases induced stress by decreasing the level of monoaminergic neurotransmitters [26]
  • Agonist of 5-HT5a receptors, role in the serotonergic regulation of the circadian cycle [27] , increases the level of 5-hydroxytryptamine (serotonin) and causes proliferation of hippocampal cells in depressed rats [28]
  • Sedative, anticonvulsant [29] , antiepileptic in animal models [30]
  • Aqueous root extracts contain appreciable amounts of GABA which could directly cause sedation, but there is some controversy surrounding the bioavailability of this compound.
  • Valepotriates , antidepressants , are found very little in galenic preparations, but the degradation products ( baldrinals and other derivatives) are active
  • Valeranone is hypotensive at 5 mg/kg
  • Valerian overdose can lead to asthenia, hypotension, heavy-headedness, mydriasis, and abdominal pain.
  • Actinidin is an attractor for cats (found in Nepeta cataria )
  • It 's isovalerenic acid that "smells like feet"


Bud properties


Properties of essential oil




Indications of the whole plant (phytotherapy)


  • Excitement, insomnia, palpitations of nervous origin
  • Neurotonic states and neuro-vegetative dystonias in adults and children, alpha sympathetic hyperfunction of prolonged stress
  • Insufficient pituitary-adrenal response
  • Sleep disorders, especially sleep onset insomnia, associated with extracts of hops [31] , even after a single administration [32] , and lemon balm
  • Valerian improves sleep quality in postmenopausal women with insomnia [33]
    • A literature review of studies published between 1950 and 2009 showed that the use of valerian, alone or in combination with hops , is associated with an improvement in certain sleep parameters, but the authors call for further trials. randomized, double-blind, placebo-controlled [34]
  • Anxiolytic and slightly anti-depressive, anxious ruminations, chronic exposure to stress, postural stress contractures (patient who loses footing), prevents memory loss in depressed patients
  • Adjuvant in smoking cessation and in epilepsy (petit mal des enfants)
  • Homeopathic indications: [35]
    • hysterical neuropathy, hyperesthesia, emotional exasperation, mood swings, decreased pain threshold, spasms, myoclonus, cramps, spasmophilia


Indications of the bud (gemmotherapy)


Specific indications of essential oil (aromatherapy)


Known or suspected mode of action



Usual formulations





Possible side effects and precautions for use


  • A review of the literature concludes that there is no element allowing to question the safety, even in cancer patients [36].
  • Interactions with cytochromes P450 [37] , [38]
  • Possible interactions with benzodiazepines [39]
  • Rare cases of hepatotoxicity (?) Following administration of a herbal mixture containing valerian , three cases of hepatotoxicity have also been reported where hepatomegaly associated with acute hepatitis with centrilobular necrosis has been observed . The damage regressed, and liver function tests returned to normal three months after stopping treatment
  • Avoid children and pregnant women
  • Toxicity of valepotriates at 400 mg/kg
