The aforementioned variables indicating which conditions respondents treated via a natural herb provide a "yes" or "no" response for each condition. Analysts interested in the conditions that natural herbs were used to treat may wish to consult the following variables, as well:

• Number of conditions treated with herbs, past 12 months (HERYCONNO)
