Deontological values to which the 2006 renewed doctors’ code adheres are not changed toward the so-called complementary or non-conventional medicines, toward the therapies that find their roots in the popular traditions and toward whichever practise not previewed from official medicine. The doctor must carefully inform the patient of what he proposes and about the alternative existing therapies. He must see that the patient is not subtracted to the more effective therapies, when these exist, and he must remember that he always operates only under its own and not delegable responsibility. The doctor cannot use secret therapies and he must always propose therapeutic practises that have some methodological foundation and that must not be imaginative or just of its personal experience. Inside of these borders the doctor has the maximum freedom of action and he must have in fact a good knowledge of the most common complementary therapies to the official medicine, in order to avoid damages for pharmacological incompatibility and to be able to integrate, in the patient’s interest, several therapeutic proposals.
