It would be difficult, if not impossible, to ascertain the action of multiple homeopathic remedies given all at once. The response of the vital force would be unpredictable and ambiguous. Though Hahnemann experimented with this approach he abandoned it as unsatisfactory. The third principle of homeopathy is The Minimum Dose. This refers to the infinitesimal doses of medicine given as well as to the repetition of dose only when necessary.
Drugs given to individuals in material doses frequently cause side effects or adverse reactions.
To curtail this problem, the homeopath administers the smallest possible dose so as to maximize beneficial effects and minimize side effects. Repetition of dose is determined by the individual's response to the remedy. Unnecessary repetition may lessen the response, even to the correct remedy. In homeopathy, less is better. The fourth principle of homeopathy is The Potentized Remedy.
