Public health covers public activities linked with cure, prevention and health promotion directed to positively influence the health of populations. As far as these criteria are met, health policies are public health. Public health holds many ethical implications. Resources and health opportunities are redistributed, ends and means of public health as well as rights and duties have to be discussed, and conflicts exist between targets. Ethical policy counselling is an important complement to natural and social scientific policy counselling. However, ethical counselling cannot solve conflicts about values and norms nor does it claim to do so. There are different theories and approaches, recommended principles differ and are in conflict with each other. It must not be expected that a generally accepted frame for public health ethical policy counselling will be developed. Public health ethics can develop an ordering effect and enforce more clarity for actors about their values and norms, but in case of unresolvable dissent between experts it can also be misused to give support to the legitimation of political decisions. Orientation of consulting activities towards the "pragmatistic model" (Habermas) and a counselling of the civil society is promising to prevent such exploitation.
