Homoeopathy has been practiced for over 200 years. It started with a German Doctor, Samuel Hahnemann who in 1796 re-discovered the principle of "like cures like" originally discovered by Hippocrates in ancient times. It means that a substance that causes symptoms of an illness in a healthy person may be used to cure those same symptoms in a sick person. For example red onion is often used for symptoms of streaming eyes as in hay fever, or coffea is given to cure symptoms of insomnia.
Homoeopathic remedies are all made from natural substances, usually plants or minerals, and are prepared by dilution many times so that none of the material substance is left in the higher dilutions, thus making them safe and free from side effects. This has led to the speculation that the remedy is a placebo, but interestingly enough, the remedy will work on tiny children and animals who don't understand the placebo effect. The remedy acts as trigger to heal one's body by its own natural ability.
This sort of medicine restores a patient to health quickly, safely and without any nasty side effects. Homoeopathy works synergistically with all other forms of therapies and also with conventional medicines. Today there are many GPs who will also treat their patients with homoeopathy if they so desire as they too feel it has a place in the healing spectrum. My own first brush with homoeopathy was experienced through a Dr, who I have to say did wonders for my children (when conventional medicine had failed us) before I could learn to treat them myself. Having been inspired by his cures I chose to follow this path to helping heal people.
