Abstract
The growing interest in the good state of health and the effort to maintain it leads to the abuse of this trend by manufacturers of various medical preparations. Consumers should be wary of products, the producers of which do not register them as drugs, emphasize their natural origin regardless of risks, declare the absence of side effects, promise to cure a wide range of diseases, do not present mechanisms of action, rely on case reports of celebrities instead of clinical studies, and on traditional systems of medicine without scientific verification. Products recommended by individuals without relevant expertise are often being sold outside the pharmacies and retail chains. Their application without critical assessment can lead to neglecting the treatment, health complications, or financial losses.
