A pilot study of herbal medicine use in a Midwest Latino population.

Background: Herbal medicine use is common in the United States, especially in immigrant populations. Understanding of this plant use is incomplete, with significant gaps in the literature for people living in the Midwest, about the plant species used, and about how home herbal medicine use interacts with allopathic medicine.

Methods: This pilot project used a qualitative research approach (interviews and focus groups, convenience sampling) to explore this topic for Latin America immigrants living in Madison, Wisconsin.

Results: Eight interviews and focus groups consisting of 42 people yielded 199 minutes of audio recordings and the mention of 57 medicinal plants. These plants were obtained from gardens, relatives and friends (abroad and local), mail order, and local retail establishments. Retail sites sold fresh plants, dried plants, spices, foods, and packaged products, ranging from 20 to over 150 plant products per site. A preponderance of plants, especially in Latino-focused stores, was food that also served a medicinal purpose. Participants mentioned 35 distinct health and disease categories for which herbal medicines were used, and sometimes, but not always, discussed plant use with their health care provider. When compared with likely Latin binomial taxonomic names, clinically relevant confusions with the use of common plant names also were identified.

Discussion: Overall, the findings presented illustrate the complexities surrounding herbal medicine use and create a case for future work to involve other demographics, and focus on botanical identification, the quantification of disclosure rates, and the development of educational interventions for physicians and patients.
