Description

For sample adults who had taken any mixed or single herbal or botanical supplement (2000) or had used natural herbs for their own health (2002 and 2012) during the past 12 months (HERYR) and sample children in 2012, HERYVAL indicates whether the person had taken valerian during the past 12 months.

Valerian was one of many alternative health treatment modalities included in the 2002 and 2012 Complementary and Alternative Health Supplements. If sample respondents gave a positive response to HERYVAL, they were asked a series of follow-up questions.

Related Variables

Additional information about use of valerian was collected for respondents who reported using valerian in the past 12 months, including variables on frequency of use. Please use the IPUMS NHIS drop-down menus and search function to learn more about these variables.
