R. A. Hope Bücher

I swear by Apollo, Asclepius, Hygieia, and all deities, to fulfill this oath and covenant to the best of my ability. I will honor my teacher as my parents, sharing my resources if needed, and regard his children as my own, teaching them this art without charge if they wish to learn. I will impart knowledge through various means to my own sons and those of my teacher, as well as to students bound by our covenant, but not to others. My practices will prioritize the well-being of patients, avoiding harm or wrongful intent. I will not administer deadly drugs or assist in abortions, and I will maintain purity and holiness in my life and practice. I will refrain from surgery, leaving it to skilled practitioners. In every home I enter, it will be for the benefit of the sick, avoiding all wrongdoing and corruption, particularly in matters of seduction, whether of free or enslaved individuals.
