"In Juggankhan v. The State of Madhya Pradesh (1965) 1 SCR 14, the accused, a registered Homoeopath, administered 24 drops of stramonium and a leaf of dhatura to the patient suffering from guinea worm. The accused had not studied the effect of such substances being administered to a human being. The poisonous contents of the leaf of dhatura, were not satisfactorily established by the prosecution. This Court exonerated the accused of the charge under Section 302 IPC. However, on a finding that stramonium and dhatura leaves are poisonous and in no system of medicine, except perhaps Ayurvedic system, the dhatura leaf is given as cure for guinea worm, the act of the accused who prescribed poisonous material without studying their probable effect was held to be a rash and negligent act. It would be seen that the profession of a Homoeopath which the accused claimed to profess did not permit use of the substance administered to the patient. The accused had no knowledge of the effect of such substance being administered and yet he did so. In this background, the inference of the accused being guilty of rash and negligent act was drawn against him. In our opinion, the principle which emerges is that a doctor who administers a medicine known to or used in a particular branch of medical profession impliedly declares that he has knowledge of that branch of science and if he does not, in fact, possess that knowledge, he is prima facie acting with rashness or negligence.
