https://en.wikipedia.org/wiki/Quackery

Quackery is the practice of fraudulent medicine.

Common elements of general quackery include fraudulent diagnoses using fraudulent diagnostic tests, as well as untested or refuted treatments, especially for serious diseases such as cancer.

Unproven, usually ineffective, and sometimes dangerous medicines and treatments have been peddled throughout human history. Theatrical performances were sometimes given to enhance the credibility of purported medicines.

The evidence-based medicine community has criticized the infiltration of quackery into mainstream academic medicine, education, and publications, accusing institutions of "diverting research time, money, and other resources from more fruitful lines of investigation in order to pursue a theory that has no basis in biology."

The term psychiatry was first coined by the German physician Johann Christian Reil in 1808 and literally means the 'medical treatment of the soul' (psych- 'soul' from Ancient Greek psykhē 'soul'; -iatry 'medical treatment' from Gk. iātrikos 'medical' from iāsthai 'to heal').

https://en.wikipedia.org/wiki/Anti-psychiatry

Anti-psychiatry is a movement based on the view that psychiatry is more damaging than helpful to patients.

Objections to psychiatry include the unreliability of psychiatric diagnosis, the definite harm associated with psychiatric medications, the failure of psychiatry to demonstrate any disease treatment mechanism for psychiatric medications, and legal concerns about human rights and civil freedom being nullified by the presence of psychiatric diagnosis.

The definitions of psychiatric diagnoses consist of combinations of phenomenological criteria, such as symptoms and signs. Psychiatric diagnostic categories are called disorders and are not validated by biological criteria, as medical diseases are; although they purport to represent medical diseases and take the form of medical diagnoses.

The influence of pharmaceutical companies is another major issue for the anti-psychiatry movement. As many critics from within and outside of psychiatry have argued, there are many financial and professional links between psychiatry, regulators, and pharmaceutical companies. Drug companies routinely fund much of the research conducted by psychiatrists, advertise medication in psychiatric journals and conferences, fund psychiatric and healthcare organizations and health promotion campaigns, and send representatives to lobby general physicians and politicians.

Psychiatric practices were introduced and framed as "treatments" for mental disorders, including inducing seizures (by electroshock, insulin or other drugs) or psychosurgery (lobotomy). In the US, beginning in 1939 through 1951, over 50,000 lobotomy operations were performed in mental hospitals.

The number of psychiatric drug prescriptions have been increasing at an extremely high rate since the 1950s. In the United States, antidepressants and tranquilizers are now the top selling class of prescription drugs, and antipsychotics and other psychiatric drugs also rank near the top, all with expanding sales.
