||The use of one remedy at a
time that has been selected according to the law of
similars is what is known as classical homoeopathy. It
takes training and skill for the classical homoeopath to
prescribe the correct remedy required in a person's case.
Using one remedy at a time does not mean only one remedy
ever is used in the patient's case. In a severe acute
illness the remedy may be changed more frequently than in
long standing chronic illness. A trained classical
homoeopath will know when to repeat the dose and when to
change the remedy. There are people who call themselves
homoeopaths who prescribe many different remedies in
combination. This is called polypharmacy and demonstrates
a lack of understanding of the law of similars.
