Quackery in MAPEH refers to the promotion of fraudulent or ignorant medical practices that lack scientific evidence and are not proven safe and effective. It is a form of health fraud that involves the advertisement, promotion, or sale of products and services that have not been scientifically proven safe and effective. Quackery is often associated with the promotion of false and unproven health schemes for profit. In the context of MAPEH, quackery is discussed to educate students about the importance of validating and ensuring that the products and services they use are legitimate and approved by different agencies.

Some common examples of quackery include questionable diagnoses using questionable diagnostic tests, as well as untested or refuted treatments, especially for serious diseases such as cancer. Quacks or charlatans who promote quackery often make exaggerated claims about their ability to heal diseases, generally for financial gain. People may yield to quackery in times of great stress, pain, or sorrow.

To avoid quackery, it is important to be aware of warning signs such as exaggerated claims, use of unusual terms, creation of fear, and a promise of secrecy and financial saving. It is also important to consult with licensed medical professionals and to seek treatments that have been scientifically proven safe and effective.
