Background: Initially considered a primarily rural, White issue, opioid use and overdose rates have risen faster for Latinos (52.5%) than for White, non-Hispanics (45.8%) from 2014 to 2016. With an estimated 45% to 65% of Latino immigrant families using Mexican traditional medicine (MTM) practices before seeking Western medical services, these practices could be used as a method to increase access to care and improve outcomes. Practice Model: Although not well known, MTM is founded on a defined set of theoretical tenets that comprise a whole medical system as defined by the National Center for Complementary and Integrative Health. Whole medical systems are characterized as complete systems of theory and practice that develop independently and parallel allopathic medicine. Classifying MTM as a whole medical system to encourage further research and utilization of traditional and complementary medicine (T&CM) practices could help improve health outcomes for Latino patients. Specific T&CM practices that could be used in opioid treatment integration to decrease stigma and increase treatment utilization are then discussed. Conclusion: Incorporating T&CM practices will allow more effective, culturally competent and culturally sensitive health care provision for Latino immigrants in the United States to decrease stigma, improve health care outcomes, and address disparities in opioid use treatment.

Bursera microphylla (BM), one of the common elephant trees, is widely distributed in the Sonoran Desert in Mexico. The Seri ethnic group in the Sonoran Desert uses BM as an anti-inflammatory and painkiller drug for the treatment of sore throat, herpes labialis, abscessed tooth, and wound healing. Dried stems and leaves of BM are used in a tea to relieve painful urination and to stimulate bronchial secretion. Furthermore, BM is used for fighting venereal diseases. To investigate the effects of the hexane fraction of resin methanol extract (BM-H) on cell growth, the acute myeloid cell line (OCI-AML3) was treated with 250, 25, or 2.5 µg/mL of BM-H. The first 2 concentrations were able to significantly decrease OCI-AML3 cell number. This reduced cell number was associated with decreased S-phase, blockade of the G2/M phase of the cell cycle, and increased cell death. Similar results were obtained on all tested tumor cell lines of different origins. We found that blockade of the cell cycle was due to upregulation of p21 protein in a p53-independent way. Increase of p21 was possibly due to upstream upregulation of p-ERK (which stabilizes p21 protein) and downregulation of p-38 (which promotes its degradation). Regarding cell death, activation of caspase-3, but not of caspase-8 or -9, was detectable after BM-H treatment. In conclusion, these data suggest that the BM’s hexane fraction inhibited proliferation of cell lines mainly by a p21-dependent, p53-independent mechanism and promoted apoptosis through activation of caspase-3, but not caspase-8 or -9.
