It is a form of medicine based on the Law of Similars and was developed by Samuel Hahnemann; homeopathy stresses self-healing which is stimulated by giving very minute doses of substances that could actually lead to symptoms of disease if administered in higher doses or to a healthy person. Homeopathy aims to instill homeostasis or balance in the body by making the immune system work in a better manner. Since the end of the 18th century, this form of medicine has enjoyed a fair rate of success as an alternative form of medicine. Homeopathy pharmacies research actively to add to their bank of medicines.
