    The practice of homeopathy was first developed by the German physician Samuel Hanuman. During research in the 1790s, Hahnemann began experimenting with quinine, an alkaloid derived from cinchona bark that was well known at the time to have a positive effect on fever. Hahnemann started dosing himself with quinine while in a state of good health, and reported in his journals that his extremities went cold, he experienced palpitations, an "infinite anxiety", a trembling and weakening of the limbs, reddening cheeks and thirst—" in short", he concluded,  "all  the  symptoms  of relapsing fever presented themselves successively..." Hahnemann’s main observation was that things which create problems for healthy people cure those problems in sick people, and this became his first principle of homeopathy: simila s/m/1/bus  (with help from the same). While diverging from the principle of apothecary practice at the time—which was contraria contraries (with help from the opposite)—the efficacy of simila similibus was reaffirmed by subsequent developments in the field of vaccinations.
    Hahnemann’s second principle was minimal dosing—treatments should be taken in the most diluted form at which they remain effective. This negated any possible toxic effects of simila similibus.
    In 1988 the French immunologist Jacques Benefits took minimal dosing to new extremes when he published a paper in the prestigious scientific journal Nature in which he suggested that very high dilutions of the anti-leg antibody could affect human basophile granulocytes, the least common of the granulocytes that make up about 0.01% to 0.3% of white blood cells. The point of controversy, however, was that the water in Benveniste’s test had been so diluted that any molecular evidence of the antibodies no longer existed. Water molecules, the researcher concluded, had a biologically active component that a journalist later termed "water memory". A number of efforts from scientists in Britain, France and the Netherlands to duplicate Benveniste’s research were unsuccessful, however, and to this day no peer-reviewed study under broadly accepted conditions has been able to confirm the validity of "water memory".
    The third principle of homeopathy is "the single remedy". Exponents of this principle believe that it would be too difficult, if not impossible, to ascertain the potential effects of multiple homeopathic remedies delivered simultaneously. If it did work, they suggest, one could not know quite why it worked, turning homeopathy into an ambiguous guessing game. If it did not work, neither patient nor practitioner would know whether the ingredients were all ineffective, or whether they were only ineffective in combination with one another. Combination remedies are gaining in popularity, but classical homeopaths who rely on the single remedy approach warn these are not more potent, nor do they provide more treatment options. The availability of combination remedies, these homeopaths suggest, has been led by consumers wanting more options, not from homeopathic research indicating their efficacy.
    Homeopathy is an extremely contentious form of medicine, with strong assertions coming from both critics and supporters of the practice.  "Homeopathy: There’s nothing in it" announces the tagline to 10:23, a major British anti-homeopathy campaign. At 10.23 a.m. on 30 January 2010, over 400 supporters of the 10:23 stood outside Boots pharmacies and swallowed an entire bottle each of homeopathic pills in an attempt to raise awareness about the fact that these remedies are made of sugar and water, with no active components. This, defenders of homeopathy say, is entirely the point. Homeopathic products do not rely on ingredients that become toxic at high doses, because the water retains the "memory" that allows the original treatment to function.
    Critics also point out the fact that homeopathic preparations have no systematic design to them, making it hard to monitor whether or not a particular treatment has been efficacious. Homeopaths embrace this uncertainty. While results may be less certain, they argue, the non-toxic nature of homeopathy means that practitioner and patient can experiment until they find something that works without concern for side effects. Traditional medicine, they argue, assaults the body with a cocktail of drugs that only tackles the symptoms of disease, while homeopathy has its sights aimed on the causes. Homeopaths suggest this approach leads to kinder, gentler, more effective treatment.
    Finally, critics allege that when homeopathy has produced good results, these are exceedingly dependent on the placebo effect, and cannot justify the resources, time and expense that the homeopathic tradition absorbs. The placebo effect is a term that describes beneficial outcomes from a treatment than can be attributed to the patient’s expectations concerning the treatment rather than from the treatment itself. Basically, the patient "thinks" himself into feeling better. Defenders suggest that homeopathy can go beyond this psychological level. They point to the successful results of homeopathy on patients who are unconscious at the time of treatment, as well as on animals.
