This law is also called as SIMILIA SIMILIBUS CURANTUR, which means 'Let likes be treated by likes' (like cures like).

In order to execute a cure and heal an ailing person, a homoeopathic physician needs to administer a drug that produces symptoms that are similar to the diseased symptoms

Hahnemann states in aphorisms 272-274,

'Only one, single, simple remedy should be administered to the patient at one time'.

The curative effect of the medicine does not depend only on the selection of a similar remedy but also on the quantity of the medicine.

Since the homoeopathic medicines act at a dynamic level, only a minute quantity of the medicine is enough to stimulate the dynamically deranged vital force to bring about the necessary curative change in a patient.

Drug proving is a systemic investigation and evaluation of the disease producing power of a substance on healthy human beings of both sexes, different age groups and people from different demography.

Vital force is the invisible vital energy that animates each organism and is the most intimate spark, the essence of the individual.

It derives all sensations and performs all the functions of life solely by means of the immaterial being (vital force), which animates the material organism in health and in disease.

We call this as ‘Immunity” of an individual

All the medicinal properties, which are latent in a substance, are extracted from their crude form for the curative purpose .
