Abstract
Valerian root contains two substances of special pharmacological interest–valepotriates and sesquiterpenes. The former, which has been used for standardization of the drug, is cytotoxic. The latter has no such effect. Both have sedative effects. A double blind test has been carried out on a preparation (VALERINA NATT) containing primarily sesquiterpenes. When compared with placebo it showed a good and significant effect on poor sleep (p less than 0.001). Forty-four percent reported perfect sleep and 89% reported improved sleep from the preparation. No side effects were observed.
