What types of quackery are there?

Quackery encompasses a range of fraudulent or unproven medical practices and treatments. Common types include alternative medicine claims, such as homeopathy and herbal remedies, which lack scientific support; pseudoscientific diets that promise rapid weight loss without evidence; and unverified devices or procedures that claim to cure diseases. Additionally, quackery can involve misleading information about vaccines or other public health interventions. Overall, it exploits vulnerable individuals seeking relief or solutions to health problems.
