Homeopathy is an alternative medical practice in which extremely dilute amounts of certain natural substances are used to treat various ailments.
Although homeopathic medicines are sold in health food stores and at high-end groceries, homeopathy is largely considered quackery. No scientific evidence supports its use; the theory of how homeopathy could work is beyond the realm of known physics; and governments worldwide are increasingly denying insurance payments to cover homeopathic treatment.
History of homeopathy
Homeopathy was developed in the late 18th century by Samuel Hahnemann, a respected doctor in Germany. Hahnemann believed that "like cures like" and that minute concentrations of a particular toxin could cure the very same symptoms it would cause in larger doses. Think poison ivy to treat rashes. This notion of "like cures like" was similar to the emerging science of inoculation and vaccination. And Hahnemann's treatments in their dilute forms were far safer than most medical practices during his time, such as bloodletting. Nevertheless, doctors — and chemists, in particular — soon came to understand that homeopathy could not work because the dilutions are implausible, diluted to the point that there is no longer any medicine in the medicine.
