From Physician's First Watch. I expect that the Alliance for Natural Health will comment on this at some point, but it made me wonder - what supplements actually should contain DNA? Don't processing methods often kill/inactivate/remove DNA but still preserve active ingredients? I would agree broadly that DNA from plants not listed on the label is worrying, but might this not sometimes be very minor contamination in carrier substances like oils, gums, resins, etc.? I also note that one of the unlisted herbs was daisy. Echinacea is in the daisy family, so could the DNA evidence be wrong?
