Homeopathy is among the worst examples of faith-based medicine... These axioms (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 (eg, Bach Flower remedies, spiritual healing, crystal therapy) is therefore not an option. We think that a belief in homeopathy exceeds the tolerance of an open mind. We should start from the premise that homeopathy cannot work and that positive evidence reflects publication bias or design flaws until proved otherwise... We wonder whether any kind of evidence would persuade homeopathic physicians of their self-delusion and challenge them to design a methodologically sound trial, which if negative would finally persuade them to shut up shop... Homeopathy is based on an absurd concept that denies progress in physics and chemistry. Some 160 years after ''Homeopathy and Its Kindred Delusions'', an essay by Oliver Wendell Holmes, we are still debating whether homeopathy is a placebo or not... Homeopathic principles are bold conjectures. There has been no spectacular corroboration of any of its founding principles... After more than 200 years, we are still waiting for homeopathy "heretics" to be proved right, during which time the advances in our understanding of disease, progress in therapeutics and surgery, and prolongation of the length and quality of life by so-called allopaths have been breathtaking. The true skeptic therefore takes pride in closed mindedness when presented with absurd assertions that contravene the laws of thermodynamics or deny progress in all branches of physics, chemistry, physiology, and medicine.

Anti-alternative: The emeritus professor of surgery at University College London wants alternative medicine banned in the NHS. Claim to fame: He described homoeopathy as a "cruel deception" in an open letter to health authority bosses. Lasting legacy: Has given a spur to the NHS to be more consistent in what it provides free and what it doesn't.〔

Re Use of ‘alternative’ medicine in the NHS. We are a group of physicians and scientists who are concerned about ways in which unproven or disproved treatments are being encouraged for general use in the NHS.... While medical practice must remain open to new discoveries for which there is convincing evidence, including any branded as ‘alternative’, it would be highly irresponsible to embrace any medicine as though it were a matter of principle.... These are not trivial matters. We urge you to take an early opportunity to review practice in your own trust with a view to ensuring that patients do not receive misleading information about the effectiveness of alternative medicines. We would also ask you to write to the Department of Health requesting evidence-based information for trusts and for patients with respect to alternative medicine.〔Michael Baum, ''et al''.
