Isovaleramide is an amide found in Valerian root. In humans, it acts as a mild anxiolytic at lower doses and as a mild sedative at higher dosages. Isovaleramide has been shown to be non-cytotoxic and does not act as a CNS stimulant. It inhibits the liver alcohol dehydrogenases and has a reported LD50 of greater than 400 mg/kg when administered intraperitoneally in mice.
