Homeopathic medicine is based on the two principles that “like cures like” and that the potency of substances increases in proportion to their dilution. In November 2009 the UK Parliament’s Science and Technology Committee heard evidence on homeopathy, with several witnesses arguing that homeopathic practice is “unethical, unreliable, and pointless”. Although this increasing scepticism about the merits of homeopathy is to be welcomed, the unethical effects of funding homeopathy on the NHS are even further-reaching than has been acknowledged.
