Herbal/Plant Remedies and Supplements Used by Hispanics/Latinxs for Diabetes: Source of Functional Foods?

Abstract

Purpose The purpose of this study was to explore the use of herbal/plant remedies and supplements for type 2 diabetes (T2DM) among Hispanics/Latinxs in North Carolina and identify demographic and diabetes-related factors associated with use of these therapies. Methods Baseline data from a family-based diabetes intervention tailored for Hispanics/Latinxs were analyzed using descriptive statistics, bivariate analyses, and logistic regression. A convenience sample of 186 adults with T2DM and adult family members with and without T2DM was recruited from community-based settings and data obtained from face-to-face interviews conducted in Spanish. Results Most participants were female (73%) with an average age of 45 years old. Among this predominantly immigrant sample (96%), 78% of participants reported being from Mexico. Sixty percent had T2DM, and average A1C was 8.7% for persons with T2DM. Nearly a third reported using 51 different remedies for diabetes management. Most ingested them concurrently with prescribed medications; however, 11.3% reported altering the dose of medications when using herbal/plant remedies or supplements. Most common items were prickly pear cactus, pineapple, celery, aloe vera, parsley, and spinach. Using herbs/plants was positively correlated with age, A1C, and years with T2DM. The odds of using herbs/plants increased 28% for every 1% increase in A1C (adjusted odds ratio = 1.28, P = .003). Conclusions Asking about herbal/plant remedy and supplement use is important. Although there is limited efficacy and safety studies for some items, multiple reported remedies are functional foods with biologically active ingredients to promote health. Patient education is needed on safe and unsafe items and use with prescribed medications.
