Homeopathy is a form of complementary medicine which relies heavily on
observation and experience. The three distinguishing characteristics
of homeopathy are that remedies are prescribed on the totality of a pe
rson's symptoms, that the remedy likely to cure a person is a dilution
of that substance which would cause the same symptoms in a healthy pe
rson, and that remedies are prepared using microdoses of substances wh
ich are diluted and then vigorously shaken. Mainstream medicine critic
izes homeopathy by saying that its gentleness has outlived its usefuln
ess and treatment successes are probably no more than placebo action.
In addition, its critics charge that homeopathy is unscientific, runs
counter to the ''laws of nature'' and will not stand up to scientific
scrutiny. Homeopaths reply that mainstream medicine is dangerous, that
homeopathy works in children and animals (usually thought resistant t
o placebo), and that several good controlled clinical trials have show
n positive results. There is a difference between showing that homeopa
thy works and adequately accounting for its mechanism of action. Clini
cal trials have concentrated on the former and remain unexplained in t
he latter.
