Homeopathy has a very effective action on CHRONIC ailments as well as in ACUTE cases. First of all, Homeopathic medicines cures the patient in a very natural way, no operation or nothing any harm it used to cure patient. Doses are very minimal - There is no chance of side effects. The Founder of Homeopath Dr. Christian Friedrich Samuel Hahnemann, was a well known person at that time as a physician before Homeopathy in the copper-mining area of Mansfeld, Saxony.
Hahnemann was dissatisfied with the state of medicine in his time. He claimed that the medicine he had been taught to practice sometimes did the patient more harm than good. So he started to investigate the causes of medicine's alleged errors. While translating William Cullen's A Treatise on the Materia Medica, Hahnemann encountered the claim that cinchona, the bark of a Peruvian tree, was effective in treating malaria because of its astringency. Hahnemann believed that other astringent substances are not effective against malaria and began to research cinchona's effect on the human body by self-application. Noting that the drug induced malaria-like symptoms in himself, he concluded that it would do so in any healthy individual. This led him to postulate a healing principle: "that which can produce a set of symptoms in a healthy individual, can treat a sick individual who is manifesting a similar set of symptoms.
From that moments to now, A lot of medicines have been proved on this principle that "like cures like". Like cinchona, there are much more crud substances in the world have been proved on this principle LIKE CURES LIKE. And now, Homeopathy has maintained its level as the second largest method of treatment in the world.
