Double blind study of a valerian preparation.
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.
