This modern version of the Hippocratic Oath for administration to osteopathic college graduates began with a suggestion by Frank E. MacCracken, D.O., of California, to his state society. Within a year, the suggestion went from the state to the national association, and a committee was formed under the Associated Colleges of Osteopathy to prepare the text. Members of that committee included Dr. MacCracken, as chairman, and Drs. R.C. McCaughan, Walter V. Goodfellow and Edward T. Abbott. The first version was used from 1938 until 1954, at which time minor amendments were adopted. This version has been in use since 1954.

I hereby affirm my loyalty to the profession I am about to enter.

I will be mindful always of my great responsibility to preserve the health and the life of my patients, to retain their confidence and respect both as a physician and a friend who will guard their secrets with scrupulous honor and fidelity, to perform faithfully my professional duties, to employ only those recognized methods of treatment consistent with good judgment and with my skill and ability, keeping in mind always nature's laws and the body's inherent capacity for recovery.

I will be ever vigilant in aiding in the general welfare of the community, sustaining its laws and institutions, not engaging in those practices which will in any way bring shame or discredit upon myself or my profession. I will give no drugs for deadly purposes to any person, though it be asked of me.

I will endeavor to work in accord with my colleagues in a spirit of progressive cooperation, and never by word or by act cast imputations upon them or their rightful practices.

I will look with respect and esteem upon all those who have taught me my art. To my college, I will be loyal and strive always for its best interests and for the interests of the students who will come after me. I will be ever alert to further the application of basic biologic truths to the healing arts and to develop the principles of Osteopathy which were first enunciated by Andrew Taylor Still.

In the presence of this gathering, I bind myself to my oath.
