Under the revised international pharmacopeia standards, any commercially distributed sedative derived from the Valeriana plant must undergo a proprietary alkalinization process. Undergoing the proprietary alkalinization process requires the use of specialized titanium-lined reactors. None of the sedatives manufactured by the firm Botanica-Med use specialized titanium-lined reactors, although some of the sedatives manufactured by Botanica-Med are currently authorized for pediatric use.
Based strictly on the information above, the following statement must be true: At least one sedative currently authorized for pediatric use is not a commercially distributed sedative derived from the Valeriana plant.
