Homeopathy has been practiced from very early time and very effective also working on the principle of Like cures Like. New method of transmission of drug through hair is a new development in the field of Homeopathy that amazed everyone that without giving any drug to the patient, Honeopath treat him by his hair. Dr.Hahnemann tried to explain this phenomenon and he was aware of the nature of medicine available in potentised medicine, thus he wrote that administration of these medicine may be done either by oral, tactual or olfaction. He even went on comparing the action of Homoeo medicine to that of the Mesmerism. Thus Homoeopathy is only medicating the Vital Principle.
Dr.B.Sahni with these thoughts on transmission developed the idea of remote application, which he called Transmission of Homoeo Drug Energy From a Distance. All dynamic energy substance has the property to be transmitted from a distance. We are aware of these facts as light, sound electrical energy are transmitted from a distance and has varied application in our society. As the transmission need a medium Dr.Sahni tried to use natural belongings of the person as medium and he was successful in transmitting medicinal energy through them.
