then classified as good medicines or bogus medicines. Hopefully, in the future, the good medicines will be embraced within conventional medicine and the bogus medicines will be abandoned. In an article entitled "Should We Maintain an Open Mind about Homeopathy?" published in the American Journal of Medicine, Michael Baum and Edzard Ernst—writing to other physicians—wrote some strong criticisms of homeopathy:Homeopathy is among the worst examples of faith-based medicine. ... These axioms [of homeopathy] are not only out of line with scientific facts but also directly opposed to them. If homeopathy is correct, much of physics, chemistry, and pharmacology must be incorrect.... To have an open mind about homeopathy or similarly implausible forms of alternative medicine (e.g., Bach flower remedies, spiritual healing, crystal therapy) is therefore not an option. More Harm Than Good? In a review of More Harm Than Good? The Moral Maze of Complementary and Alternative Medicine doctor Harriet Hall calls Ernst the "world's foremost expert on the claims and the evidence (or lack thereof) for Complementary and Alternative Medicine (CAM)." In this 2018 book by Springer Publishing, Ernst and co-author and medical ethicist, Kevin Smith take a different approach from Trick or Treatment which is to speak not to the "practitioners and patients" (of CAM) but to ethicists and the scientific community. "It was written to inform, not to entertain. It is not a easy or 'fun' read, but it is an important one".

The authors have written out the most common excuses that CAM practitioners will make when "confronted with evidence that their CAM modality is not as effective or safe as they claim", then answered the top 10 with rebuttals. The argument that CAM helps even as a placebo is addressed in full. Early retirement from Exeter Ernst was accused by Prince Charles' private secretary of having breached a confidentiality agreement regarding the 2005 Smallwood report. After being subjected to a "very unpleasant" investigation by the University of Exeter, the university "accepted his innocence but continued, in his view, to treat him as 'persona non grata'. All fundraising for his unit ceased, forcing him to use up its core funding and allow its 15 staff to drift away." Writing in 2022, after Charles' accession to the throne, Ernst said, "There never
