Valerian (Valeriana Officinalis L.) is a herbaceous plant and its root has traditionally been used for medicinal purposes. It is included in the European Pharmacopoeia for its relaxing properties in situations of stress or for sleep disorders.
The root contains essential oil with terpenic compounds. It also provides flavonoids and amino acids such as glutamine, arginine and GABA, which contribute to its sedative and sleep-inducing action by increasing GABAergic transmission. It provides spasmolytic action on smooth muscles, i.e. it helps to relax them.
Valerian relieves episodes of mild nervous tension, tension headaches, nervous spasms, and insomnia due to mental stress, taken as a dietary supplement or as a herbal tea. It is not a medicine and is not addictive. It is often combined with other relaxing plant extracts such as hop, lemon balm and passionflower.
If you are looking for a sleep-inducing effect, taking the valerian supplement an hour or two before going to bed is advisable. Because of its sedative effect, it should be avoided just before driving or operating heavy machinery. The residual sedative effect on the next day is significantly minimised if taken the night before.
Valerian essential oil can also be used diluted on the skin for massage, thanks to its relaxing and antispasmodic effect. However, it should not be ingested or inhaled and is not suitable for use by children under the age of 12, during pregnancy or breastfeeding. Always use each product according to the instructions on the label.
Remember that dietary supplements are not a substitute for a balanced diet. When in doubt about the use and dosage of a product containing valerian extract, always consult a healthcare professional.
