The 2002 NHIS recognized 74 conditions (including an "other" category) that respondents could have treated with natural herbs. (See HERYTREAT for the full list.) To obtain responses to HERYCON1, HERYCON2, and HERYCON3, the interviewer first asked, "For what health problems or conditions did you use natural herbs?" After recording all answers, the interviewer displayed the list of conditions reported by the respondent and asked, "Which three of these are the most bothersome?"

Respondents were then asked, "How much do you think natural herbs helped your (display for each condition)? Would you say a great deal, some, only a little, or not at all?" Responses to this question are reported in HERYCON1HELP, HERYCON2HELP, and HERYCON3HELP.

Variables similar to HERYCON2HELP, which report the degree of help provided by other modalities of alternative medicine for the second of the three most bothersome conditions, include:

• Acupuncture (ACUCON2HELP)

• Ayurveda (AYUCON2HELP)

• Biofeedback (BIOCON2HELP)

• Chelation (CHECON2HELP)

• Chiropractic care (COMCON2HELP)
