People, generally, have been heard saying that the Homoeopathic medicines are slow acting, but the fact is contrary. Experience has shown that the infinitely small doses of the indicated Homoeopathic medicine when used singly in proper dose as explained by Hahnemann in his ?Organon? act like charm, especially in acute diseases of various kinds (it can be said that in all cases of acute diseases of various kinds). Often the results are simply astonishing. The results confirm the proposition as related by Hahnemann in Aphorism 149 of his fifth edition of Organon. Some so called Homoeopaths who use combinations or practice polypharmacy, put forward the lame excuse that everything has greatly changed since the time of Hahnemann. No doubt, lot of changes has taken place during past two centuries, since the time of Hahnemann. When Hahnemann discovered Homoeopathy, even the microscope was not used in the field of medicine, today there are very sophisticated electronic gadgets in use to locate minutest changes in the physiology and pathology of an individual. But, the laws of nature, which came into being in the beginning of life, not to say during the past two centuries, is there any change in these laws of nature?
