Homoeopathy also know as Homœopathy was introduced by a German physician named Samuel Hahnemann in 1796.
Homeopathy is a system of therapy based on the concept that disease can be treated with heavily diluted preparations which are thought to cause effects in healthy people similar to the symptoms presented in an illness.
The idea of a homeopathic remedy is similar to taking a vaccine for an illness, which then activates the immune system to respond to an attack, relieving the symptoms of the illness or disease itself.
