In most countries, it is a legal requirement for a medical doctor to be licensed or registered.
In general, this entails a medical degree from a university and accreditation by a medical board or an equivalent national organization, which may ask the applicant to pass exams.
This restricts the considerable legal authority of the medical profession to physicians that are trained and qualified by national standards.
It is also intended as an assurance to patients and as a safeguard against charlatans that practice inadequate medicine for personal gain.
While the laws generally require medical doctors to be trained in "evidence based", Western, or Hippocratic Medicine, they are not intended to discourage different paradigms of health.

Section 22 enshrines freedom of trade occupation and profession.
This set of rights is unique among human rights instruments.
The Section states “Every citizen has the right to choose their trade, occupation or profession freely.
The practice of a trade, occupation or profession may be regulated by law.” 
Regulation of a profession defines the practice of the profession and describes the boundaries within which it operates, including the requirements and qualifications to practise the profession.
The primary mandate of any regulatory college is to protect the public interest from unqualified, incompetent or unfit practitioners.
Regulation brings credibility to the profession.
Practitioners of a regulated profession are subject to a code of ethics and standards of practice.
Self-regulation allows a profession to act as an agent of the government in regulating its members because the government acknowledges that the profession has the special knowledge required to set standards and judge the conduct of its members through peer review. 
Hamilton states that a well regulated militia composed of the people will be more uniform and beneficial to the "public defense" of Americans.
He argues that an excessively regulated militia can harm a nation's work force, as not everyone can leave their profession to go through military exercises.
Thus, a smaller, but still well-regulated militia, is the answer.
This force will be further complemented by the "people at large," who can "stand ready with arms to defend their rights and those of their fellow-citizens."
In the end, Hamilton concludes that the militia, as it is constituted directly of the people and managed by the states, is not a danger to liberty when called into use by other states to do things such as quell insurrections.
The precis is incorrect in its inference that "people at large" means the general populace which stands ready with arms.
Hamilton argues "This will not only lessen the call for military establishments, but if circumstances should at any time oblige the government to form an army of any magnitude that army can never be formidable to the liberties of the people while there is a large body of citizens, little, if at all, inferior to them in discipline and the use of arms, who stand ready to defend their own rights and those of their fellow-citizens."
Hamilton's reference to a large body of citizens is not the "people at large" which may be armed, but is not disciplined, trained, organized, or regulated.
He is instead supporting his argument that an organized and regulated body of citizens, trained, and led by experienced officers known as "the militia" is the proper means to protect the citizenry against the potential harm that could be posed by a national army and would also be well-prepared to be the basis for a national army if that need arises.
