In Ernst's book "More Good Than Harm? The Moral Maze of Complementary and Alternative Medicine", he and ethicist Kevin Smith call Charles "foolish and immoral", and "conclude that it is not possible to practice alternative medicine ethically". Ernst further claims that the private secretary of the Prince contacted the vice chancellor of Exeter University to investigate Ernst's complaints against the "Smallwood Report", which the Prince had commissioned in 2005. While Ernst was "found not to be guilty of any wrong-doing, all local support at Exeter stopped, which eventually led to my early retirement."
