Valerian prepn. consists of a Valerianaceae total extract, obtd. with a low-boiling lipophilic solvent (pref. hexane, ethyl acetate or CH2Cl2), in a polyhydric alcohol, a fatty oil and/or an essential oil (pref. glycerol, propanediol, olive oil and/or valerian oil). The prepn. is stable, and retains good sedative and strong spasmolytic activity after prolonged storage. Valerian prepns. are useful as mild sedatives which can be repeatedly administered without causing addiction or side-effects. |
