ABC's Blumenthal added that ABC and some of its nonprofit herb expert associates have taken leadership in the United States in the past three years in helping to bring to the herb and dietary supplement industry's attention the problem of accidental and intentional adulteration of herbal raw materials. ABC is the managing partner in an international consortium of independent analytical laboratories, nonprofit organizations, industry companies, trade associations, and others who are supporting the ABC-AHP-NCNPR Botanical Adulterants Program, which ABC is conducting with the nonprofit American Herbal Pharmacopoeia (AHP) and the NCNPR at the University of Mississippi. The NCNPR is a Center of Excellence with the US Food and Drug Administration. It analyzes botanical ingredients on contract for the FDA and develops laboratory analytical methods for determining proper identity and the possible presence of contaminants and/or adulterants in botanical raw materials and extracts.

Dr. Gafner, lead author of the ABC critique, is the technical manager of the Botanical Adulterants Program. Botanist Steven Foster, another critique co-author, is Chair of the ABC Board of Trustees and the author or co-author of four of the five extensive, highly peer-reviewed papers on adulteration of herbs published in HerbalGram by the Botanical Adulterants Program.

The ABC paper ends with the following statement, calling for revision of the DNA paper:


"[I]n our view, and in the opinion of expert reviewers of this critique, and with all due respect to the authors and BMC Medicine, the journal should retract this paper, and require that the authors address various errors and ambiguities by appropriately rewriting, correcting, and resubmitting it to the journal.
