Our objective was to investigate the use of and attitudes about herbal medicines in a variety of groups. One hundred twenty-five surveys were collected from people of varying professional, ethnic, age, and economic groups from the Lehigh Valley, PA and Orange County, NY. Surveys were constructed based on the Theory of Planned Behavior. Attitudes toward use of herbal medicines, subjective norm (looking at the views of the subjects' family and friends), and control over access to herbal medicines were quantified to compare how gender, profession, and ethnicity affect past and future intent of use of herbal medicines. Data were analyzed using regression and path analyses. There were significant differences among ethnic groups and between the health versus non-health professionals, but not between gender groups, in their attitudes toward and use of herbal medicines. A Northern Pennsylvania Latino sample compared to a non-Hispanic sample had a more positive attitude towards herbal medicines as well as a different definition of what substances they consider to be herbal medicines. Attitudes predicted herbal medicine use in both of these ethnic groups; however, correlates of a positive attitude were different in the two groups.
