For sample adults in 2000 who had taken herbal or botanical supplements (HERYR) for at least one month (HERYMONO) during the past 12 months, HERYDAYNO reports answers to the question, "During (the/those) month(s), about how many (days/days per month) did you take herbal supplements?" HERYDAYNO indicates the number of units--i.e., days--reported by the respondent. HERYDAYNO must be interpreted in conjunction with the complementary variable HERYDAYTP, which indicates whether the time unit used in the respondent's answer was days per week, days per month, or "other."

The National Center for Health Statistics recoded the data in HERYDAYTP and HERYDAYNO into two new variables with consistent time units across respondents: HERYDPW (Number of days per week took herbal supplements during past 12 months) and HERYDPM (Number of days per month took herbal supplements during past 12 months).


HERYDAYNO is only available for 2000.
