The aforementioned variables indicating which conditions respondents prevented via a second herbal supplement provide a "yes" or "no" response for each condition.

For sample adults who took a first herbal supplement in the past 30 days to prevent a specific condition (HER1PREV), parallel information was collected on the conditions respondents tried to prevent with that first herbal supplement. (See, for example, HER1PADD.)

These include:

• Condition for which 2nd herbal supplement was taken to prevent most (HER2PMOST)

• Condition count for 2nd herbal supplement used to prevent a condition (HER2PCONNO)
