Summary

Valerian (Valeriana officinalis, Caprifoliaceae) is a perennial flowering plant native to Europe and Asia. In the summer when the mature plant may have a height of 1.5 metres (5 ft), it bears sweetly scented pink or white flowers that attract many fly species, especially hoverflies of the genus Eristalis. It is consumed as food by the larvae of some Lepidoptera (butterfly and moth) species, including the grey pug. Crude extract of Valerian root may have sedative and anxiolytic effects, and is commonly sold in dietary supplement capsules to promote sleep. (Source: Wiki)

Hepatotoxicity Description

Valerian has been implicated in a small number of cases of clinically apparent liver injury, but usually in combination with other botanicals such as skullcap or black cohosh. In view of its wide scale use, valerian has to be considered a very rare cause of hepatic injury. In published cases, the latency to onset ranged from 3 to 12 weeks and the pattern of enzyme elevations was usually hepatocellular or mixed hepatocellular-cholestatic. The liver injury was usually mild-to-moderate in severity with recovery within 2 to 4 months of stopping. Immunoallergic and autoimmune features were not present. Severe cases with features of hepatic failure have been described, but usually in association with other potentially hepatotoxic herbals. (Source: LiverTox)
