Homeopathy is a system of medicine developed in the 18th century by Dr Samuel Hahnemann, which approaches good health in a holistic way – taking account of the whole person and not just the symptoms or ‘disease’. The fundamental principle is that ‘like cures like’ – i.e. the Dr will select a homeopathic remedy made from a natural substance which would usually produce the very symptoms being shown, but in a tiny dose which has been ‘potentised’ to be effective. A simple example might be that a homeopathic dose of Allium cepa (made from onions) could help someone who has watering eyes and a streaming nose – exactly the symptoms we experience when we chop an onion.
